Executive Summary

Phoenix Public Works is carrying a confirmed $20.8 million structural shortfall into FY2025–26, with enterprise fund reserves projected to approach zero by FY2027–28. Staff costs are up 32%, vehicle costs up 52%, and construction costs up 40% since 2020 — while residential rates have been frozen. The proposed 45% rate increase over three years will face sustained political resistance in a state where neighboring municipalities have already cancelled recycling programs and moved to biweekly collection to survive the same cost pressures.

Behind the fiscal crisis sits a larger structural problem: Phoenix manages approximately one million tons of manufacturing feedstock annually at a blended cost of ~$154 per ton, escalating at an estimated 5.9% per year, with no recovery mechanism, no Circular Royalty™, and no path to meeting the Reimagine Phoenix 50%-by-2030 diversion target under existing policy constraints. The city's total identifiable contingent liabilities — PFAS exposure, CCR obligations, legacy site remediation, and a $1.32 billion COPERS pension deficit — exceed $2 billion. None of these liabilities are resolved by a rate increase.

Carbotura Inc. is proposing to site an Advanced Circular Manufacturing (ACM) facility at the Resource Innovation Campus (RIC) on the 27th Avenue corridor — city-owned land already co-located with Phoenix's transfer station, MRF, and compost facility. Carbotura would finance, build, own, and operate the facility entirely at its own cost. Phoenix would contribute zero capital. In return, Phoenix would receive a Total Material Conversion (TMC) Fee of $150 per ton — $4 below its current blended disposal cost from Day 1 — and a Circular Royalty™ beginning in Year 2, permanently exceeding the TMC Fee at 120% of its value and escalating at 1% per year for 30 years. Under Arizona's SB 1156 (2021) advanced recycling statute, the facility would operate under a manufacturing permit — not a solid waste permit — representing one of the cleanest permitting paths in the country.

Five Findings This Document Addresses

The Disposal Cost Trap. Phoenix's blended disposal cost of ~$154/ton is escalating at an estimated 5.9%/year. Over 30 years at that trajectory, the status quo consumes an estimated $862M in disposal expenditure for the 400 TPD stream alone — with no return. The proposed TMC Fee of $150/ton reverses this from Day 1, and the Circular Royalty™ generates a positive return beginning Year 2.
The Liability Wall. Phoenix faces a combined contingent liability profile exceeding $2 billion: PFAS exposure ($50M–$200M+), CCR obligations ($50M–$500M+), WQARF/Superfund legacy sites ($500M–$1B+), and a $1.32B COPERS pension deficit at 74.65% funded. ACM title transfer arrests forward PFAS accrual, eliminates new closure obligations on converted feedstock streams, and removes Phoenix from the permit holder position for material conversion going forward.
The Capacity Gap. Phoenix generates approximately one million tons of manufacturing feedstock annually, growing 3–5% per year. The city's SR-85 Landfill closure timeline is not publicly disclosed, and the regional disposal market is controlled by two operators whose combined market share exceeds 83%. The proposed 2,000 TPD Tier 2 configuration would process approximately 730,000 tons per year — representing a transformative shift in Phoenix's diversion infrastructure without any new landfill siting.
The Diversion Target Gap. Phoenix's Reimagine Phoenix 50%-by-2030 diversion target has no identified programmatic pathway under current Arizona preemption law. Arizona's SB 1156 (2021) advanced recycling reclassification provides a legislative opening that no opt-in, voluntarist program can replicate: ACM feedstock is removed from the solid waste stream by statute at delivery, not at a landfill gate.
The Enterprise Fund Crisis. The $20.8M FY2025–26 shortfall is structural, not cyclical. It cannot be solved by a rate increase that faces political resistance and will still compound at 5.9%/year once enacted. The ACM TMC Fee permanently replaces a rising disposal cost with a fixed-plus-1%-per-year contractual rate, while the Circular Royalty™ provides a new revenue line beginning in Year 2 — directly improving the enterprise fund's structural balance.

How This Document Is Organized This report has three sections. Section I (Status Quo) documents Phoenix's current disposal cost profile, infrastructure constraints, and liability exposure based on the Phoenix Metro Waste Industry Intelligence Report 2025. Section II (Economic Impact Report) responds directly to each Status Quo finding with the ACM correction. Section III (Proposal) presents the full three-tier build plan, financial model, and community returns for the proposed partnership at the Resource Innovation Campus.

Source: Phoenix Metro Waste Industry Intelligence Report 2025, s12. Volume-weighted blended average across primary disposal streams. Equal-weighting applied where per-stream tonnage data is unavailable. Residential MSW collection at $240/ton represents the dominant cost driver at an estimated 55% of volume.

Phoenix Annual Cash Flow — Costs (Negative) vs. Circular Royalty™ & Net Community Benefit (Positive) — 400 TPD

Illustrative projection — 400 TPD configuration, annual dollar flows. Costs shown as negative (below zero): Status Quo disposal cost escalates at 5.9%/year; TMC Fee is near-flat at 1%/year. Circular Royalty™ is positive (above zero), starting Year 2 at +$16.4M. The Net Community Benefit (bold teal delta) compounds from +$0.4M in Year 1 to +$55.1M by Year 15, reflecting Circular Royalty™ received plus disposal cost avoided minus TMC Fee paid. Not a contractual commitment.

30-Year Projected Cumulative Disposal Expenditure — Status Quo

Illustrative projection — Status Quo trajectory only. FWDC $154/ton compounding at 5.9%/year with no community return. Staged annual tonnage used for all tier calculations. Not a contractual commitment.

⚠ The Escalation Trap Phoenix's blended disposal cost of approximately $154 per ton is not a stable floor — it is a starting point on a compounding cost curve driven by labor inflation (staff costs up 32% since 2020), vehicle replacement (up 52%), and construction (up 40%). At an estimated 5.9% annual escalation, the same ton of manufacturing feedstock that costs $154 to process today will cost $274 by Year 10 and $486 by Year 20. The city's enterprise fund is already in structural deficit at today's rates; every year without an alternative processing mechanism widens that deficit. The proposed TMC Fee of $150 per ton, escalating at only 1% per year, permanently decouples Phoenix from this compounding cost exposure — from Day 1.

Status Quo Assessment

SQ2 Capacity & Infrastructure

Source: Phoenix Metro Waste Industry Intelligence Report 2025, Section 8 — Regional Analysis. Phoenix's disposal infrastructure is characterized by a single city-owned landfill with an undisclosed closure timeline, an absence of Waste-to-Energy capacity, two city-operated transfer stations, and a population growth rate generating 20,000+ additional tons per year with no corresponding diversion infrastructure investment.

Population Growth vs. Disposal Infrastructure Capacity

Maricopa County Growth

+57,471 residents in 2023–24 — 3rd largest numeric county gain in the U.S. At current per-capita generation rates, this adds approximately 20,000+ tons per year of manufacturing feedstock requiring collection and disposal.

HIGH confidence · U.S. Census Bureau

Phoenix City Feedstock Volume

Approximately 1 million tons per year currently, growing at 3–5% per year without diversion improvements. By 2035, Phoenix city alone is projected to generate 1.3–1.4 million tons per year.

MED confidence · EPA factors + city data

Capital Investment Gap

The 5-year Phoenix Public Works capital improvement plan allocates $172 million — focused entirely on maintaining existing infrastructure, not adding new processing capacity to serve growth communities.

HIGH confidence · Phoenix CIP

Statewide Growth Horizon

Arizona's population is projected to grow from ~7.7 million (2025) to 9.8 million by 2060 (+26%). Pinal County, Phoenix MSA fringe, is projected to grow +118%. Disposal infrastructure planning is absent for this horizon.

HIGH confidence · AZ Office of Economic Opportunity

🚨 The Capacity Cliff — Undisclosed Timeline, Certain Endpoint Unlike many U.S. cities where landfill closure dates are published and planned for, Phoenix has not publicly disclosed the remaining capacity or projected closure date of its SR-85 Landfill. What is known: the facility opened in 2006, has a Cell 2 capital requirement of $9 million in the current 5-year plan, and carries an accruing closure and post-closure obligation that is embedded in the Public Works capital plan without separate disclosure. Maricopa County's landfill capacity data gap — a direct consequence of ADEQ's absence of mandatory reporting requirements — means the region is planning growth-driven waste volumes without confirmed knowledge of its own disposal runway. When SR-85 reaches capacity, Phoenix will have no city-owned alternative: no WTE facility, no backup landfill, and a private market controlled by two operators who set their own access terms.

Status Quo Assessment

SQ3 Liability Exposure

Source: Phoenix Metro Waste Industry Intelligence Report 2025, Section 13 — Financial Liabilities. The Phoenix metro public waste sector carries a multi-billion-dollar aggregate liability profile distributed across seven categories. Most figures are partially or fully off-balance-sheet. Under GASB standards, these contingent liabilities are not fully reflected in current operating budgets — but they are real obligations that will demand capital as regulatory and legal timelines converge.

HIGH High-confidence figure — named operator disclosure or statutory record MED Medium-confidence — estimated from benchmarks or partial data LOW Low-confidence — modeled estimate; data gap exists

Sub-A — PFAS / Biosolids

$50M–$200M+

Potential biosolids PFAS compliance exposure for Phoenix Water if EPA finalizes 40 CFR Part 503 PFAS limits. Includes treatment plant upgrades ($50–200M+), land application site investigation, and Class A conversion capital ($50–150M). Phoenix Water has no publicly disclosed PFAS-biosolids management plan. ADEQ 2022 screening confirmed PFAS presence in Arizona biosolids.

Off-balance-sheet / No plan disclosed LOW (Phoenix-specific)

Sub-B — CCR / Coal Ash

$50M–$500M+

Estimated CCR impoundment closure exposure for APS and SRP: APS Cholla 420-acre Fly Ash Pond + 80-acre Bottom Ash Pond (Oct 2028 target — 7 years behind original EPA deadline); Four Corners Upper Retention Sump (mandatory closure for location restriction failure); SRP Coronado ($DATA GAP — no SEC filing). Broad range reflects closure method and groundwater remediation uncertainty.

Partially accrued — APS disclosure range MED (APS) / LOW (SRP)

Sub-C — Landfill Closure (National)

$2.7B–$3.3B

Republic Services: $2,144M accrued closure + $2,703M total environmental liability nationally (208 active + 126 closed landfills, Dec 31 2024). Waste Management: $3,057M accrued closure + $3,279M total nationally. City of Phoenix SR-85 closure reserve: not separately disclosed; embedded in Public Works capital plan. Arizona-specific shares undisclosed.

Partially accrued — national disclosure only HIGH (national)

Sub-D — Tire Stockpile Remediation

$5M–$25M

Legacy orphan tire stockpile remediation liability in Maricopa County. ADEQ Waste Tire Fund allocates up to $250K/quarter ($1M/year) — consistently fully utilized, indicating demand meets or exceeds funding. Maricopa County has recycled 20M+ tires since 2003 but current orphan site inventory is unquantified.

Partially funded — ADEQ Tire Fund LOW

Sub-E — Superfund / WQARF Legacy Sites

$500M–$1B+

~7 federal NPL sites + 19 of Arizona's 37 WQARF sites in Maricopa County with waste industry connections. Aggregate remediation liability spread over multi-decade timelines; public/private split unresolved. Includes 19th Avenue Landfill (NPL-listed, removed — perpetual institutional controls at city expense). WQARF capped at $18M/yr statewide.

Multi-decade obligation — partially public MED

Sub-F — Financial Assurance Gap

Unknown gap

No ADEQ-published analysis compares required financial assurance against independently estimated actual closure costs for Arizona's major landfills. Construction cost inflation in Phoenix metro has consistently exceeded national averages since 2020. ADEQ's annual IPD adjustment mechanism may structurally lag actual closure cost increases — widening an unquantified gap.

Unquantified — no gap analysis published LOW — data gap

Sub-G — COPERS Pension Deficit

$1.32B

City of Phoenix Employees' Retirement System (COPERS) unfunded liability: $1.32 billion as of June 2025, funded ratio 74.65%. Reason Foundation estimates true deficit may be understated by $702M if assumed rates of return prove unrealistic. Phoenix Public Works' 626-person workforce is a material share of total city employees. Any workforce expansion to meet growth-driven service demands directly increases this obligation.

Accrued & tracked on balance sheet HIGH

TOTAL IDENTIFIABLE EXPOSURE

~$2B–$2.05B+

Quantifiable Phoenix-area liability components: COPERS $1.32B (accrued) + PFAS/biosolids $50–200M+ + tire stockpile $5–25M + WQARF partial public share. CCR and national landfill closure exposure are additional but undisclosed at the Phoenix-specific level. This figure is a floor, not a ceiling.

Composite MED confidence

⚠ The PFAS Disclosure Trap ADEQ's 2022 screening confirmed PFAS in Arizona biosolids. A peer-reviewed study (Scientific Reports, 2025) documented PFAS concentrations at depth in agricultural soils receiving decades of Class B land application — the same pathway used by Phoenix Water's Synagro contractor serving 2.6 million people. EPA's April 2024 CERCLA designation of PFOA and PFOS as hazardous substances creates current liability exposure without any finalized rule. Phoenix Water's NPDES permit (AZ0020524, expiring April 2028) contains no PFAS-specific biosolids conditions. Maine's complete ban on biosolids land application is a live precedent. Phoenix has no publicly disclosed management plan. When the rule is finalized — not if — the absence of a plan becomes an active credit event.

SQ4 Market & Operator Landscape

Source: Phoenix Metro Waste Industry Intelligence Report 2025, Sections 2, 3, 7, and 10. Phoenix's disposal market is one of the most concentrated in the United States: two private operators hold an estimated 83% of the private hauling market and effectively control all commercial disposal capacity, operating within a regulatory environment specifically structured by Arizona statute to limit municipal policy tools.

The Preemption Architecture — Structural Lock-In by Statute

Statute / Legislation	Year	Effect on Phoenix	Industry Beneficiary
ARS §9-500.38 / §11-269.16 (HB 2238 / SB 1241)	2015/2016	Preempts all municipal bans on auxiliary containers, deposit-return schemes, and recycling mandates. ALEC model bill.	Republic Services, WM, plastics industry, Arizona Chamber
SB 1487	2016	Authorizes state to withhold shared revenue from non-complying municipalities. Enforcement mechanism for §9-500.38.	Industry — eliminates local policy experimentation
SB 1156 (Advanced Recycling)	2021	Reclassifies pyrolysis/gasification as manufacturing — removes from ADEQ solid waste jurisdiction. Arizona was 12th state to adopt ALEC model language. ACM facility operates under manufacturing permit.	Advanced recycling / ACM operators — manufacturing permit, not solid waste permit
HB 2411 (CCR "not more stringent")	2022	Authorizes ADEQ CCR program but mandates it cannot exceed EPA federal standards. Prevents stricter state groundwater/closure requirements.	APS, SRP — limits Arizona's enforcement ambition
SB 1439 (proposed)	2026	Would prohibit cities from recommending items for recycling bins unless "actively recycled." Further restricts municipal communication on diversion.	Haulers — reduces public pressure on recycling improvement

ADEQ Annual Budget

~$6.1 million for the entire Arizona Department of Environmental Quality waste program — regulating a multi-billion-dollar industry. Chronically under-resourced.

Republic Federal Lobbying

~$585,000 in 2024; ~$300,000 in Q1–Q3 2025. Company states over 92% of political contributions made at local or state level — where Republic's primary regulators operate.

HHI Disposal Score

~3,954 — "Highly Concentrated" per DOJ/FTC guidelines (threshold: 2,500). Phoenix's disposal market is among the most concentrated in the U.S. for a major metro.

SB 1156 ACM Opening

Arizona is a manufacturing-permit state for ACM. No ADEQ solid waste facility plan required for pyrolysis/gasification-based processing. Shortest permitting path in the national ACM deployment landscape.

Structural Lock-In: What Phoenix Cannot Do Under Current Law Arizona's preemption architecture removes the core policy tools available in peer states: mandatory commercial recycling, organic waste diversion mandates, pay-as-you-throw pricing, deposit-return schemes, and municipal bag bans. Phoenix cannot mandate that residents or businesses reduce their disposal volumes, cannot penalize high-volume generators, and cannot offer financial incentives for diversion that would threaten the incumbent operators' revenue base. The result: diversion gains must come entirely from voluntary participation, which has plateaued at 36% for years. The one statutory opening that does exist — SB 1156's manufacturing reclassification of ACM — is precisely the legislative vehicle through which the proposed partnership would operate.

Status Quo Assessment

SQ5 Goals vs. Reality Gap

Source: Phoenix Metro Waste Industry Intelligence Report 2025, Section 11 — Goals vs. Reality. Phoenix has established some of the most ambitious waste diversion commitments of any Sun Belt city. The gap between those commitments and documented outcomes is not attributable to a lack of effort — it is structural, rooted in a state regulatory architecture that strips municipalities of the tools proven to close that gap in comparable cities.

Policy Targets vs. Current Performance — Reimagine Phoenix Assessment

Diversion Rate Benchmarking — Phoenix vs. Peer Cities

Reported Diversion / Recycling Rate — Peer City Comparison

Phoenix's current 36% diversion rate is 14 percentage points below its own 2030 target, exceeds only states with no recycling infrastructure, and sits well below peer cities with regulatory diversion tools. Los Angeles at 70%+ operates under SB 1383 organic waste mandates and CRV deposit-return — tools preempted by Arizona statute.

Active Structural Pain Points — Phoenix Waste Sector (s9 Summary)

🚨

Enterprise Fund Insolvency Risk

Confirmed $20.8M structural shortfall in FY2025–26. Reserves projected near-zero by FY2027–28. Staff costs up 32%, vehicles up 52%, construction up 40% since 2020. Proposed 45% rate increase faces political resistance in a state where Surprise cancelled recycling entirely.

CRITICAL

📉

Diversion Rate Stagnation

Plateaued at ~36% for years. 2020 target of 40% missed. 2030 target of 50% requires matching 11 years of prior gain in 4 years — widely viewed as unachievable under current preemption framework. An estimated 65% of what residents discard is recyclable or compostable.

HIGH

🌱

Organics Program Scale Failure

Phoenix generates 270,000 tons of food waste annually. Curbside organics participation is below 4% of 164,500 eligible households — capturing fewer than 10,000 tons/year. Proposed fee increase from $5 to $10.83/month (July 2026) projects to further suppress enrollment.

HIGH

🧪

PFAS / Biosolids — No Management Plan

ADEQ 2022 confirmed PFAS in Arizona biosolids. Peer-reviewed study (2025) found PFAS at depth in soils receiving Class B land application — the Phoenix Water / Synagro pathway. EPA CERCLA designation creates current liability without finalized rule. No Phoenix Water management plan publicly disclosed.

Growth Outpacing Infrastructure

Maricopa County added 57,471 residents in 2023–24 — 3rd largest numeric county gain in the U.S. New developments in Buckeye, Goodyear, Queen Creek, and Pinal County fringe are outpacing transfer station capacity planning and landfill access logistics.

Pension Obligation Growth

COPERS carries $1.32B unfunded liability at 74.65% funded ratio. Any workforce expansion to meet growth-driven collection demands directly increases the accrued pension obligation — creating structural tension between service delivery and long-term fiscal sustainability.

⚠ The Accountability Gap Of the eight goal domains assessed in the Phoenix Metro Waste Intelligence Report, one target was met (long-term tire recycling volume), one has no target and no mechanism to create one (statewide recycling rate), one lacks any public management plan (biosolids PFAS), two have been missed without correction (the 2020 diversion target and the 2021 CCR compliance deadline), and two are on trajectories that make their stated targets mathematically implausible under current law (50% diversion by 2030, organics program). The structural absence of mandatory reporting, binding targets, and enforcement mechanisms means there is no accountability framework that would compel corrective action even where failures are fully documented. The proposed ACM partnership operates entirely outside this accountability vacuum: it is a contractual manufacturing arrangement governed by the Circular Offtake Agreement, not a voluntary policy commitment subject to legislative preemption.

Economic Impact Report

EIR1 Cost Transformation

This section corrects SQ1 (Disposal Cost Profile). The status quo disposal cost trajectory for Phoenix is a compounding liability with no return mechanism. The proposed Advanced Circular Manufacturing partnership replaces that trajectory with a fixed-plus-1%-per-year TMC Fee and a Circular Royalty™ projected to exceed the TMC Fee from Year 2 onward under proposed COA terms.

Status Quo Finding — SQ1 ~$154/ton · $862M projected 30-yr spend

Phoenix's blended Full-Weighted Disposal Cost is approximately $154/ton, escalating at an estimated 5.9%/year. Over 30 years at current trajectory, the 400 TPD stream alone consumes an estimated $862 million in disposal expenditure — generating zero financial return to Phoenix. The enterprise fund is already in structural deficit at these rates.

→

ACM Correction $150/ton TMC Fee · $1.96B–$9.80B 30-yr return

The proposed TMC Fee of $150/ton is $4 below Phoenix's current blended disposal cost from Day 1. The Circular Royalty™ — 120% of TMC Fee, paid annually from Year 2 — generates $840M–$4.2B in projected royalty income over 30 years depending on tier. Combined with $1.12B–$5.6B in projected avoided disposal costs, the three configurations generate $1.96B, $6.86B, and $9.80B in combined 30-year community benefit respectively.

The Payment Flip — How the Economics Reverse

Under every existing disposal contract Phoenix has ever signed, money flows one direction: out. The TMC Fee paid to Carbotura is operationally identical to a disposal fee — an operating expenditure replacing an operating expenditure — with one structural difference. Beginning 13 months after the first manufacturing feedstock delivery, Carbotura pays Phoenix a Circular Royalty™ equal to 120% of every dollar Phoenix paid in TMC Fees during the prior year, escalating at 1% per year for the full 30-year term of the proposed Circular Offtake Agreement. This is not a rebate, a credit, or a discount. It is a separate cash payment — operating revenue recognized annually under GASB 33.

The crossover happens in Year 2: from that point forward, Phoenix receives more in Circular Royalty™ than it pays in TMC Fees every single year. Meanwhile, the disposal cost that Phoenix would otherwise be paying grows at 5.9%/year while the TMC Fee grows at only 1%/year — creating a widening gap that compounds for three decades. The proposed TMC Fee of $150/ton, escalating to $186/ton by Year 20, replaces a disposal cost projected to reach $486/ton by the same date.

Year-by-Year Community Financial Position — 400 TPD Minimum Configuration

★ Crossover Point: Year 2 — Phoenix Is Permanently Net Positive Beginning in Year 2, the Circular Royalty™ payment Phoenix receives from Carbotura exceeds the TMC Fee Phoenix pays to Carbotura. From that point forward, Phoenix never pays more than it receives in combined royalty and avoided-cost value. The gap widens every year: by Year 10, the 400 TPD configuration generates a projected net annual benefit of $42.3 million — on a stream that currently costs $22.5 million per year with no return. This is not a grant, a subsidy, or a government transfer. It is the structure of the proposed Circular Offtake Agreement.

For Council — The Payment Flip in Plain Language "We already pay to manage our manufacturing feedstock. Is this just another fee?" Not quite. The TMC Fee is $4 per ton less than what Phoenix currently pays — so Phoenix saves from Day 1. Then, starting in Year 2, Carbotura pays Phoenix back 120 cents for every dollar Phoenix paid in TMC Fees the previous year. Think of it like a refinery that uses your raw material input: you get paid for the feedstock, and you no longer have disposal costs. The same expenditure Phoenix has always made — restructured so that it returns revenue instead of disappearing into a landfill.

EIR2 Liability Elimination

This section corrects SQ3 (Liability Exposure). Phoenix faces a combined identifiable contingent liability profile exceeding $2 billion — most of it off-balance-sheet. Advanced Circular Manufacturing does not merely reduce these liabilities over time; it arrests their forward growth through a single legal mechanism: title transfer at feedstock receipt.

Status Quo Finding — SQ3 $2B+ identifiable contingent exposure

Phoenix's status quo liability profile: PFAS/biosolids $50M–$200M+ (no plan); CCR $50M–$500M+; landfill closure obligations (undisclosed Phoenix-specific share of $2.7B–$3.3B national); WQARF/Superfund $500M–$1B+; tire stockpile $5–$25M; COPERS pension $1.32B (74.65% funded). Most forward-accruing liabilities have no disclosed management strategy. Current trajectory: every year of status quo adds to these figures.

ACM Correction Forward accrual arrested at title transfer

Under the proposed Circular Offtake Agreement, title to manufacturing feedstock transfers to Carbotura at the moment of receipt at the ACM facility. From that point forward, Phoenix is no longer the responsible party for that material under RCRA Subtitle D, CERCLA, or ADEQ permitting — and generates no new landfill closure obligation, no new PFAS land-application exposure, and no new post-closure monitoring requirement from the ACM-processed stream. The proposed ACM facility holds manufacturing permits (NAICS 325xxx/331xxx), not solid waste facility permits.

Legacy obligations unaffected; new accumulation arrested.

Title Transfer Is the Key The legal mechanism underlying every liability correction in this section is title transfer. Under Arizona's SB 1156 (2021), thermochemical processing of recovered feedstocks is classified as manufacturing — removing it from ADEQ solid waste jurisdiction. Under the proposed Circular Offtake Agreement, title to manufacturing feedstock passes to Carbotura Inc. at the moment of receipt at the ACM facility. From that moment, the material is a manufacturing input, not a solid waste. Phoenix is no longer its custodian, its regulator, or its responsible party. GASB 49 (Pollution Remediation Obligations) provides that when the responsible party for contamination changes, the prior party's obligation to accrue for future remediation costs is arrested. The same legal principle — title-based transfer of environmental responsibility — applies to PFAS, to landfill closure, and to post-closure monitoring obligations for the ACM-diverted stream.

For Finance Officers — GASB Treatment of Liability Elimination GASB 49 (Pollution Remediation Obligations): Title transfer to Carbotura at feedstock receipt extinguishes Phoenix's obligation to recognize new PFAS-related or closure-related remediation provisions for the ACM stream under GASB 49 going forward. The obligation simply does not accrue because Phoenix is no longer the responsible party from that point. GASB 60 (Service Concession Arrangements): The proposed COA is a service concession arrangement under GASB 60 — Carbotura provides the capital, operates the facility, and returns revenue. No capital obligation appears on Phoenix's balance sheet. GASB 62/87: The 30-year TMC Fee commitment is an operating expenditure — not a lease, not a bond, not debt. It replaces current disposal contracts on the operating budget line. Community should confirm accounting treatment with its auditors prior to executing any agreement.

EIR3 Capacity Solution

This section corrects SQ2 (Capacity & Infrastructure). Phoenix has no published landfill closure timeline for SR-85, no WTE capacity, and no alternative processing infrastructure beyond a single organics facility operating at 4% of its potential throughput. The proposed ACM deployment at the Resource Innovation Campus resolves all three deficits — without a new landfill, without incineration, and without a solid waste facility permit.

Status Quo Finding — SQ2 SR-85 closure: undisclosed · zero WTE

Phoenix's SR-85 Landfill closure timeline is not publicly disclosed. No WTE or alternative thermal processing capacity exists anywhere in the Phoenix metro. The compost facility operates at <4% of capacity. Maricopa County is adding 57,000+ residents per year — generating 20,000+ additional tons of manufacturing feedstock annually with no corresponding processing infrastructure.

ACM Correction 400 / 1,400 / 2,000 TPD online by Q2 2027–2028

The proposed ACM facility at the Resource Innovation Campus (RIC), 27th Avenue corridor, would be online at 400 TPD as early as Q2 2027 — before any confirmed landfill closure date. The 1,000 TPD building shell is constructed once; modules are added at $55M/100 TPD with 6-month notice. The 2,000 TPD Tier 2 configuration processes 730,000 tons per year — approximately 73% of Phoenix city's entire annual manufacturing feedstock volume.

ACM Commissioning Timeline vs. Disposal Infrastructure Trajectory — Phoenix RIC

Construction begins ~18 months before Q2 2027 COD (approximately Q4 2025). The 1,000 TPD building shell is constructed once; additional modules are added at $55M/100 TPD. Tier 1 reaches full 1,400 TPD by Q3 2030; Tier 2 reaches 2,000 TPD by Q3 2032. SR-85 Landfill closure timeline is not publicly disclosed; all three tier configurations would be operating before any capacity cliff scenario.

The Manufacturing Permit Pathway — Arizona SB 1156 Advantage

SB 1156 (2021) Reclassification

Arizona reclassified pyrolysis, gasification, depolymerization, and similar thermochemical processes as manufacturing, removing them from ADEQ solid waste jurisdiction. The ACM facility requires an industrial manufacturing permit — not a solid waste facility plan. Arizona was the 12th state to adopt this framework. This is the cleanest ACM permitting path in the country.

Resource Innovation Campus (RIC)

The proposed site at the 27th Avenue RIC corridor is city-owned land already co-located with Phoenix's existing transfer station, MRF (Balcones Resources), and compost facility (WeCare Denali). Feedstock logistics are already established. No new siting, no new land acquisition, no new community impact assessment required for a brownfield industrial campus.

No New Landfill — Ever

The 1,000 TPD building shell is constructed once, in the first phase, regardless of which tier is selected. All future module additions — from 400 TPD to 2,000 TPD and beyond — require only module installation at $55M per 100 TPD, with 6-month notice. No new civil engineering, no new permitting, no new community siting for expansion.

Island Mode — No Utility Dependency

The Captive PEM hydrogen configuration uses internally generated renewable hydrogen to power the facility. Phoenix ACM operates in Island Mode — no utility grid dependency, no utility cost exposure. In a city where summer temperatures exceed 115°F and utility costs are among the highest in the Southwest, this is a material operational advantage.

No New Landfill Required — The Infrastructure Math At Tier 2 (2,000 TPD), the proposed ACM facility would process approximately 730,000 tons of manufacturing feedstock per year — 73% of Phoenix city's current total volume. The remaining 27% continues to SR-85. If Phoenix's volume grows at 4% per year, the 2,000 TPD ACM configuration absorbs the city's entire growth trajectory through 2035 without any new landfill siting. The capital cost to Phoenix for this infrastructure outcome: zero. The capital cost to Carbotura: $1.12 billion, 100% privately financed.

Economic Impact Report

EIR4 Jobs & Economic Impact

The proposed ACM facility creates a net new manufacturing employment base in Phoenix — not a repositioning of existing waste sector jobs, but a new category of industrial employment at manufacturing wages, funded entirely by Carbotura Inc.'s capital commitment.

ACM Economic Contribution — City of Phoenix 546 Direct Manufacturing Jobs — Tier 1 (1,400 TPD)

At the Tier 1 (1,400 TPD) configuration, the proposed ACM facility creates 546 full-time manufacturing positions at an estimated $110,000 average annual salary — generating $60.1M in direct annual payroll. Total Carbotura investment: $790M. Capital required from City of Phoenix: $0. The facility is classified under NAICS 325xxx/331xxx (manufacturing), not NAICS 562 (waste management), placing it in the highest-wage tier of industrial employment classifications.

Employment Structure & Local Hire Policy

Local Hire First

Carbotura's standard operating protocol prioritizes local hire from the host community for all manufacturing roles. Training provided in-house at no cost to employees or the municipality. No specialized prior qualifications required for entry-level positions.

Role Categories

Manufacturing operators (40%), process engineers (20%), logistics and feedstock management (15%), quality and laboratory (12%), maintenance and systems (10%), management (3%). All positions full-time with benefits.

Regional Wage Comparison

ACM average salary of $110,000/yr compares favorably to Phoenix metro median household income (~$72,000) and significantly exceeds average waste sector wages (~$45,000–$65,000). Represents a net wage uplift for any transitioning waste sector workers.

AZ State Incentive Programs

Arizona's Job Training Program (JTED) and Quality Jobs Tax Credit program provide potential upside for qualifying manufacturing employers. City of Phoenix Economic Development incentives available for qualifying industrial employers meeting local hire and wage thresholds. Labeled as upside — not in base case projections.

For Economic Development — Jobs Classification & Incentive Pathway 546 direct manufacturing jobs at $110,000 average salary = $60.1M annual payroll injection at Tier 1. The ACM facility is classified under NAICS 325xxx (chemical manufacturing) / 331xxx (primary metal manufacturing) — not NAICS 562 (waste management). This matters for economic development purposes: manufacturing incentives, enterprise zone programs, and state job creation grants available to NAICS 325/331 employers are not available to solid waste operations. Arizona's Quality Jobs Tax Credit (up to $9,000/qualified employee over 3 years for qualifying manufacturers) could represent $4.9M in state tax credit value at Tier 1 — labeled as potential upside only, subject to program eligibility confirmation.

ACM fiscal contribution is a net new addition, not a replacement of incumbent contributions.

For Economic Development — Why ACM Fiscal Impact Exceeds Legacy Operators $1.13B in projected 30-year fiscal contributions at Tier 2. Legacy disposal operators (Republic Services and WM) generate disposal revenue that flows to shareholders in Phoenix, Dallas, and national markets. The ACM facility generates manufacturing revenue — subject to Arizona Transaction Privilege Tax on manufactured goods sales, property tax on $1.12B of privately-financed capital improvements assessed to Carbotura, and payroll tax on 780 positions at above-median wages. None of these fiscal streams require Phoenix to contribute a dollar of capital. The NAICS 325/331 manufacturing classification also positions the facility for state economic development infrastructure programs unavailable to NAICS 562 waste operators.

Economic Impact Report

EIR6 Balance Sheet Transformation

This section corrects SQ3 (Liability Exposure) and SQ5 (Goals vs. Reality). The proposed Circular Offtake Agreement restructures Phoenix's relationship with its manufacturing feedstock from a cost center with growing liabilities into a revenue-generating partnership with arrested forward liabilities. This section applies GASB accounting standards applicable to U.S. municipalities.

Status Quo Finding — SQ3 & SQ5 Rising costs · growing liabilities · no royalty

Status quo: TMC Fee equivalent cost $154/ton escalating 5.9%/yr; PFAS, closure, and pension liabilities accruing with no forward management plan; zero royalty revenue from feedstock stream; enterprise fund in structural deficit. Unrestricted Net Position trajectory: deteriorating.

→

ACM Correction TMC Fee = operating cost · Royalty = operating revenue · UNP improves from Year 2

With proposed COA: TMC Fee ($150/ton) is an operating expenditure under GASB 62 — replaces disposal budget line, no new debt. Circular Royalty™ is operating revenue under GASB 33 — recognized annually from Year 2. PFAS forward accrual arrested under GASB 49. No capital on Phoenix's balance sheet (GASB 60 service concession). Unrestricted Net Position trajectory: improving from Year 2.

GASB Accounting Treatment — Each Standard, One Line

GASB Standard	Applies To	Treatment Under Proposed COA	Impact on Phoenix Balance Sheet / P&L
GASB 60	Circular Offtake Agreement as service concession arrangement	Carbotura provides capital, operates facility, returns revenue. COA = service concession. No Phoenix capital asset on books.	No capital obligation. No debt. No depreciation. Zero balance sheet impact from facility construction.
GASB 33	Circular Royalty™ receipts	Non-exchange revenue — recognized when earned (annually, from Year 2). Not conditional on Phoenix's actions.	Operating revenue — credited to General Revenues annually from Year 2. Improves operating surplus trajectory year-over-year.
GASB 49	PFAS and pollution remediation obligations	Title transfer at feedstock receipt: Phoenix is no longer responsible party for ACM-processed stream. New PFAS accrual obligation arrested.	Forward PFAS remediation provision does not accrue for ACM stream from date of COD. Eliminates one of the two largest off-balance-sheet risk items.
GASB 62 / 87	TMC Fee — 30-year commitment	TMC Fee is an operating expenditure — categorically equivalent to current disposal contracts. Not a lease. Not debt. Same budget line as current disposal costs.	Operating expenditure only. No new debt instruments, no long-term liability recognition, no lease obligation. Replaces existing disposal contract line.
GASB 34	Unrestricted Net Position (UNP)	Royalty revenue (inflow) + liability accrual arrest (reduced provision) + disposal cost reduction = net improvement to UNP from Year 2.	UNP trajectory reverses from deteriorating to improving beginning Year 2. Each subsequent year of operation improves the cumulative UNP position.

Key GASB Takeaway Under the proposed COA structure, the TMC Fee is an operating expenditure — categorically equivalent to current disposal contracts under GASB 62 and 87. The Circular Royalty™ is operating revenue recognized annually under GASB 33. The community's Unrestricted Net Position is projected to improve from Year 2 onward as legacy PFAS liability accrual is arrested and royalty revenue begins. City of Phoenix should confirm accounting treatment with its auditors prior to executing any agreement.

Balance Sheet Position Comparison — Status Quo vs. With Proposed COA

Balance Sheet / P&L Item	Status Quo Trajectory	With Proposed COA (Year 2+)
Disposal operating expenditure	$154/ton → $274/ton by Year 10 (+5.9%/yr)	$150/ton → $165/ton by Year 10 (+1%/yr only) under GASB 62 operating line
Royalty / revenue from feedstock	$0 — no return mechanism exists	$16.4M (Yr 2) → $28.4M (Yr 10) at 400 TPD under GASB 33 operating revenue
PFAS remediation provision (forward)	Growing annually — no management plan; $50–200M+ potential accrual when "likely and estimable" threshold triggered	Forward accrual arrested for ACM stream from COD date under GASB 49 title transfer
Capital obligation (facility)	N/A — existing infrastructure aging	$0 — Carbotura owns and finances the facility entirely under GASB 60 service concession
New long-term debt / lease	Risk: future capital spend to replace aging infrastructure	$0 — TMC Fee is operating expenditure, not debt under GASB 87
Unrestricted Net Position trajectory	Deteriorating: enterprise fund shortfall $20.8M in FY25–26; worsening absent rate increase	Improving from Year 2: royalty revenue + arrested liabilities + operating cost stabilization under GASB 34

Municipal Credit Quality — How the COA Affects Phoenix's Credit Position

The GASB accounting outcomes documented above do not remain on Phoenix's financial statements alone — they flow directly into the credit quality metrics used by Moody's Investors Service, S&P Global Ratings, and Fitch Ratings when assessing municipal creditworthiness. Every improvement in operating surplus, every arrested contingent liability, and every new revenue line described in this section is a direct input to the four dimensions these agencies evaluate when determining whether a municipality's credit rating should be upgraded, maintained, or downgraded. Phoenix's bond rating is not currently published in the available data for this document; the analysis below applies to Phoenix's current credit position regardless of its specific rating level, and the structural improvements described are applicable to any credit tier.

How Rating Agencies Assess U.S. Municipalities — The Four Dimensions Moody's, S&P, and Fitch evaluate municipal credit quality across four primary dimensions: (1) Operating financial performance — surplus or deficit trajectory, revenue diversity, expenditure control; (2) Debt burden — outstanding debt relative to assessed value and revenue base, new debt issuance; (3) Contingent liability exposure — unrecognized or off-balance-sheet obligations including environmental liabilities and pension deficits; (4) Revenue diversification — concentration risk, fee-based vs. tax-based revenue mix. Under the status quo trajectory, all four dimensions are deteriorating for Phoenix: the enterprise fund is in structural deficit, pension obligations are underfunded at 74.65%, PFAS liabilities are off-balance-sheet and growing, and revenue is concentrated in residential service fees facing political resistance. Under the proposed COA, all four dimensions reverse.

Credit Assessment Input Grid — Status Quo vs. With Proposed COA

Credit Assessment Input	Status Quo Trajectory	With Proposed COA	GASB Mechanism
Operating Surplus / Deficit	$20.8M structural shortfall FY25–26; growing absent 45% rate increase that faces political resistance. Enterprise fund near-zero reserves projected FY27–28.	Circular Royalty™ of $16.4M–$28.4M/yr (400 TPD) added to operating revenues from Year 2. TMC Fee replaces higher-escalating disposal line at $4/ton less from Day 1. Operating surplus trajectory improves each year.	GASB 33 (royalty as operating revenue) + GASB 62 (TMC Fee as operating cost, not escalating at 5.9%)
Debt Burden	Risk: future capital investment required to address aging infrastructure and SR-85 landfill closure. Any new landfill site would require bond financing — adding to debt burden metrics.	No new debt instruments. No bond issuance required for ACM infrastructure. $0 capital commitment from Phoenix. Carbotura's $240M–$1.12B investment appears on Carbotura's balance sheet only.	GASB 60 (service concession — no Phoenix capital asset) + GASB 87 (TMC Fee = operating, not lease/debt)
Contingent Liability Exposure	$2B+ identified off-balance-sheet exposure: PFAS $50–200M+ (no plan); landfill closure (undisclosed); WQARF $500M–$1B+; COPERS $1.32B at 74.65% funded. PFAS CERCLA designation creates current exposure — once threshold met, recognition is mandatory and sudden.	Forward PFAS accrual arrested for ACM stream from COD. No new closure obligation from ACM-diverted tonnage. COPERS funded ratio trajectory improves as royalty revenue expands enterprise fund surplus available for contributions. Contingent liability profile is improving, not growing.	GASB 49 (title transfer arrests pollution remediation provision) + improved operating position supporting pension contributions
Revenue Diversification	Revenue concentrated in residential service fees ($33.20/month) — politically constrained, facing 45% increase proposal with significant resistance. Zero manufacturing revenue. Zero royalty income.	Circular Royalty™ adds a new, non-rate-increase, non-tax revenue stream: $16.4M–$85.8M/yr depending on tier. Revenue base diversifies from single residential fee source to include manufacturing royalty — directly improving concentration risk metrics evaluated by rating agencies.	GASB 33 (royalty = non-exchange operating revenue, recognized annually — independent of residential rate structure)

⚠ The PFAS Disclosure Trap — A Latent Credit Event GASB 49 requires recognition of pollution remediation obligations when a triggering event makes a liability "probable and estimable." For Phoenix, the regulatory trigger is advancing: EPA's April 2024 CERCLA designation of PFOA/PFOS as hazardous substances, combined with EPA's January 2025 draft biosolids risk assessment, creates an environment where Phoenix Water's PFAS exposure from the 91st Avenue WWTP / Synagro land application pathway will move from "contingent" to "probable and estimable" — likely before the current NPDES permit expires in April 2028. When that threshold is crossed, the sudden recognition of $50M–$200M+ in previously unaccrued PFAS remediation obligations on Phoenix's balance sheet is a material credit event — simultaneously increasing debt-equivalent contingent liabilities, reducing operating flexibility, and triggering rating agency inquiry. The proposed COA arrests forward PFAS accrual from the ACM-diverted stream before this trigger is pulled — meaning the liability that eventually surfaces is smaller, the trajectory is demonstrably improving at the time of disclosure, and Phoenix enters the disclosure event with an active management strategy rather than no plan.

The Borrowing Cost Chain — Savings That Compound Across Every Capital Program

Every improvement in Phoenix's credit position reduces the interest rate on every future bond issuance — infrastructure bonds, transportation bonds, public safety capital, school facilities. Even a modest reduction in borrowing spread generates compounding savings across Phoenix's capital program over a 20-year horizon. The following table illustrates the order-of-magnitude impact using a conservative estimated future debt base for a city of Phoenix's size (population 1.67M × $800 per capita capital program = ~$1.34B illustrative future debt base).

Scenario	Rate Reduction	Illustrative Debt Base	Annual Saving	20-yr Cumulative Saving
Conservative	25 basis points	~$1.34B	~$3.35M/yr	~$67M
Moderate	50 basis points	~$1.34B	~$6.70M/yr	~$134M
Full Corridor	50 basis points	~$2.68B (2× base)	~$13.4M/yr	~$268M

Illustrative only. Credit rating changes depend on multiple factors beyond the proposed COA. Debt base is an illustrative estimate using population × per-capita capital program assumption. Does not constitute credit rating advice. 20-year cumulative saving does not account for future debt issuance increases or interest rate environment changes.

The Full Credit Benefit Statement — Four Dimensions, One Partnership The proposed Carbotura COA addresses all four dimensions used by Moody's, S&P, and Fitch to assess Phoenix's credit quality — simultaneously and from a single operating decision. Operating surplus improves as Circular Royalty™ revenue adds to the enterprise fund from Year 2 and TMC Fee escalation is capped at 1%/yr versus 5.9%/yr for legacy disposal. Debt burden does not increase as the $240M–$1.12B ACM facility is 100% Carbotura-financed with no bond, lease, or capital obligation from Phoenix. Contingent liability exposure is actively managed rather than passively accumulating — PFAS forward accrual arrested, closure obligations eliminated for ACM stream, disclosure event trajectory improving before regulatory trigger. Revenue diversification expands as Circular Royalty™ creates a new non-rate-increase, non-tax revenue stream that does not require a council vote or face political resistance. Before any PFAS disclosure event forces rating agency inquiry, Phoenix can demonstrate all four inputs moving favorably. This is the same expenditure — restructured to improve the credit position of the City of Phoenix for the next 30 years.

For Finance Officers & CAOs — The Credit Rating Conversation "How do we explain the credit quality impact to our rating agency?" Four talking points, using GASB standard names: (1) Operating surplus improvement: "The Circular Royalty™, recognized annually under GASB 33, adds $X million in operating revenue to the enterprise fund beginning Year 2 — improving the operating surplus trajectory without a residential rate increase." (2) No new debt: "The COA is an operating expenditure under GASB 62/87 — the same budget line as existing disposal contracts. No bonds, no leases, no capital obligations. The $1.12B facility investment is entirely on Carbotura's balance sheet under GASB 60." (3) Active contingent liability management: "Forward PFAS accrual for the ACM stream is arrested under GASB 49 from the date of first delivery — before the CERCLA regulatory trigger is likely to reach the 'probable and estimable' threshold. We are managing this liability proactively, not waiting for a mandatory recognition event." (4) Revenue diversification: "The enterprise fund now has two revenue streams — residential service fees and manufacturing royalties — reducing concentration risk in the fee-based revenue base." Community should engage its rating agency prior to COA execution to obtain agency-specific guidance on credit treatment.

Economic Impact Report

EIR7 Environmental Correction

This section corrects SQ3 (PFAS liability) and SQ5 (Reimagine Phoenix goals gap). The proposed ACM facility at the RIC delivers the environmental outcomes Phoenix's Reimagine Phoenix initiative committed to but cannot achieve under current policy constraints — without incineration, without ash residue, and with near-zero air emissions design.

Status Quo Finding — SQ3 & SQ5 PFAS $50M–$200M+ · diversion 36% (target 50%)

Phoenix's PFAS exposure from biosolids land application has no disclosed management plan. The 91st Avenue WWTP / Synagro pathway exposes 2.6 million people's wastewater biosolids to escalating CERCLA liability. Simultaneously, Phoenix's 36% diversion rate sits 14 percentage points below its own 50%-by-2030 target with no programmatic pathway to close that gap under Arizona's preemption framework.

→

ACM Correction Operates without combustion · no ash · PFAS engineered for elimination

The Recyclotron operates in an anoxic, non-combustion environment — no flame, no ash residue, no stack emissions from combustion. The ACM process is engineered for complete molecular breakdown of PFAS compounds. Diverted feedstock is removed from the solid waste stream by statute (SB 1156) at delivery — counting immediately toward Phoenix's Reimagine Phoenix diversion goals. At Tier 2, 730,000 tons per year — 73% of Phoenix city's feedstock volume — diverted annually.

Annual Diversion Impact — All Three Tiers

Metric	400 TPD Minimum	1,400 TPD Tier 1	2,000 TPD Tier 2
Annual tons diverted from legacy disposal	146,000 tons/yr	511,000 tons/yr	730,000 tons/yr
% of Phoenix city feedstock volume (~1M tons/yr)	~14.6%	~51.1%	~73.0%
Contribution to Reimagine Phoenix 50% goal	14.6 ppt of 50% target	51.1% — target met at Tier 1	73% — significantly exceeds target
Estimated GHG reduction (CO₂e/yr) Conservative estimate: landfill methane avoided only (~0.6 tons CO₂e/ton, EPA factors). Carbotura's full carbon-negative design profile — including no combustion emissions, carbon sequestration pathways, and §45Q-eligible CO₂ mineralisation — implies a materially larger reduction per Voice Guide Section 9 performance metrics. The figures below use the conservative landfill-methane-only basis for defensibility.	~87,600 tons CO₂e/yr	~306,600 tons CO₂e/yr	~438,000 tons CO₂e/yr
Combustion / incineration	Not combustion, not incineration. The Regenesis Protocol operates in an anoxic environment using Microwave Catalytic Reforming — no oxygen, no flame, no combustion stack emissions. This is molecular disintegration, not thermal destruction.
Ash residue generated	None — no ash from ACM process. No new ash disposal liability.
New Liquifact (leachate) generation from ACM stream	Liquifact extracted in Pregenesis (liquid fraction) is recovered entirely as Renewable Refined Water (DI) — a saleable manufactured product. No Liquifact is discharged from the ACM process; no landfill leachate generated from ACM-diverted stream.
PFAS handling	ACM Recyclotron protocol engineered for complete molecular breakdown of PFAS compounds. No PFAS-containing land application from ACM-processed stream.

ACM Environmental Profile vs. Current Landfill Disposition

Environmental Parameter	Current Landfill Disposition (SR-85)	ACM Disposition (Proposed)
Landfill gas (methane) generation	Active — though desert climate produces 3–4× less LFG than humid landfills (k-value 0.006–0.023/yr vs. 0.04–0.21). SR-85 has no confirmed LFG capture project.	No LFG generated from ACM-processed stream. Near-zero LFG generation from ACM-processed stream. No organic decomposition pathway — feedstock undergoes molecular reforming, not landfilling. Designed for near-zero methane from ACM-diverted volume.
PFAS migration pathway	PFAS-containing materials enter landfill; potential leachate migration to groundwater; post-closure monitoring obligation extends 30+ years.	PFAS compounds subjected to molecular breakdown in ACM Recyclotron protocol. No PFAS in land application. No new PFAS leachate pathway from ACM stream.
Post-closure monitoring obligation	30-year minimum RCRA post-closure monitoring period; cost estimated $50,000–$150,000+/acre in Arizona's construction-cost environment.	No post-closure obligation from ACM-processed stream. Title transfers to Carbotura at receipt; manufacturing facility environmental obligations held by Carbotura.
Air emissions	Passive methane venting if LFG capture absent; dust from operations; odor potential in surrounding communities.	Near-zero emissions design. Anoxic processing environment. No combustion-related stack emissions. Air quality permit: manufacturing classification.
Groundwater monitoring	RCRA Subtitle D monitoring requirements; potential corrective action if contamination detected; SR-85 in arid Buckeye environment but monitoring obligation perpetual.	No new groundwater monitoring obligation from ACM stream. Manufacturing facility permit does not carry RCRA groundwater monitoring requirements.

Reimagine Phoenix Goal Alignment — ACM as the Missing Tool

50% Diversion by 2030

The Tier 1 (1,400 TPD) configuration processes 511,000 tons/year — 51.1% of Phoenix city's current volume. Tier 1 alone exceeds the 2030 diversion target. Unlike voluntary recycling programs limited by Arizona's preemption framework, ACM diversion operates by statute (SB 1156) and contract — not by resident opt-in.

Zero Waste by 2050 (90%)

The Tier 2 (2,000 TPD) configuration processes 730,000 tons/year — 73% of current city volume. Supplemented by the existing MRF (Balcones Resources), organics program (WeCare Denali), and expanding recycling rates, the 90% diversion target for 2050 has a credible programmatic pathway for the first time.

PFAS Biosolids — Active Strategy

The Phoenix Water / Synagro biosolids stream can be routed to the ACM facility as a co-feedstock, subjecting PFAS compounds to the ACM molecular breakdown protocol. This converts Phoenix Water's largest undisclosed liability into a managed, contracted process — providing an active PFAS management strategy for the first time before the NPDES permit expiry in April 2028.

Reporting & Accountability

Unlike voluntary diversion programs with no enforcement mechanism, the proposed COA includes contractual throughput reporting, annual performance metrics, and independent verification. Every ton processed through the ACM facility is a documented diversion event — countable toward Reimagine Phoenix goals with contractual certainty.

Environmental Credit Upside — Not in Base Case, Available at Scale

For Council — What "Near-Zero" Means vs. Current Trajectory "Isn't this just incineration with better branding?" No. Incineration burns material in the presence of oxygen — producing ash, stack gases, and CO₂ emissions that require air quality permits, ash disposal contracts, and post-combustion monitoring. The ACM Recyclotron operates in an anoxic environment with no oxygen and no flame. Nothing combusts. The molecular structure of input materials is reformed — not burned — into engineered manufacturing outputs. The contrast to Phoenix's current trajectory: SR-85 Landfill generates methane (a greenhouse gas 28× more potent than CO₂), produces leachate requiring perpetual management, creates 30+ years of post-closure monitoring obligations, and accepts PFAS-containing materials with no treatment. The proposed ACM facility generates none of these outcomes for any ton it processes.

All figures are illustrative projections. Carbotura Inc. makes no contractual commitment prior to execution of a signed Circular Offtake Agreement.

1. Capital Commitment — 100% Carbotura-Financed

Carbotura Inc. finances, designs, builds, and owns the ACM facility entirely from its own capital. The building shell is constructed at 1,000 TPD capacity in Phase 1 regardless of which tier is selected — meaning the civil engineering, foundation, and primary structure are built once. Phoenix contributes zero capital at any tier. The CAPEX commitment ranges from $240M (400 TPD) to $790M (1,400 TPD) to $1.12B (2,000 TPD) — all privately financed. Future expansion beyond the initial tier requires only module additions at $55M per 100 TPD, with 6-month notice to Phoenix, no new site work, and no new permitting process.

2. Job Creation — Local Hire First

The proposed facility creates 156 / 546 / 780 direct manufacturing FTE positions (400 / 1,400 / 2,000 TPD) at an estimated $110,000 average annual salary, classified under NAICS 325xxx/331xxx (manufacturing). Carbotura's standard protocol prioritizes local hire from Phoenix's workforce for all positions. All training is provided by Carbotura at no cost. Annual direct payroll: $17.2M / $60.1M / $85.8M. Applying the standard 2.5× regional economic multiplier, total employment supported: 390 / 1,365 / 1,950 positions. Zero workforce capital required from Phoenix.

3. Community Financial Return — Circular Royalty™ from Year 2

The Circular Royalty™ is Carbotura's payment to Phoenix — separate from and in addition to any disposal cost savings. Beginning 13 months after first delivery (Year 2), Carbotura pays Phoenix 120% of the prior year's TMC Fee payments, escalating at 1% per year for the full 30-year COA term. This means Phoenix is projected to receive more from Carbotura in Circular Royalty™ than it pays in TMC Fees, every year from Year 2 onward under the proposed COA. The Community Crossover Point is Year 2 — standard for all tiers. Projected 30-year Circular Royalty™ totals: ~$840M (400 TPD) / ~$2.94B (1,400 TPD) / ~$4.20B (2,000 TPD).

4. Fiscal Impact — Net New Tax Base

As a manufacturing facility, the ACM campus generates property tax on Carbotura's capital improvements, Arizona Transaction Privilege Tax on RevCon™ product sales, and payroll-related state income tax on 780 manufacturing positions. Projected 30-year total fiscal contribution: ~$232M (400 TPD) / ~$793M (1,400 TPD) / ~$1.13B (2,000 TPD). These are net new fiscal contributions — not replacements of existing operator contributions. Arizona NAICS 325/331 classification makes the facility eligible for Quality Jobs Tax Credits and other state manufacturing incentive programs (labeled as potential upside only).

5. Environmental Commitment — Operates Without Combustion

The ACM Recyclotron operates without combustion in an anoxic molecular reforming environment — no ash, no stack emissions from combustion, no new Liquifact from ACM-processed feedstock. PFAS compounds are subjected to the ACM molecular breakdown protocol — no land application of ACM-processed material. The facility operates in Island Mode via captive PEM hydrogen — no utility grid dependency. Annual GHG reduction from landfill methane avoided: ~87,600 / ~306,600 / ~438,000 tons CO₂e (all tiers). Diversion contribution to Reimagine Phoenix goals: 14.6% / 51.1% / 73.0% of city feedstock volume (Tier 1 alone exceeds the 50%-by-2030 target).

P1 About ACM & Technology

Advanced Circular Manufacturing (ACM) is Carbotura's proprietary integration of 35+ commercially established component technologies, orchestrated by AI-optimized process control, to convert manufacturing feedstock into a portfolio of high-value renewable manufactured products. The engineering innovation is the integration — not novel chemistry.

The Four ACM Protocols — From Feedstock Intake to RevCon™

Pregenesis

Feedstock intake, characterization, sorting, and preparation. Removes contaminants that would reduce product yield or quality. Establishes feedstock specification for subsequent protocols. Automated optical and AI-guided sorting.

Intake & Preparation

Regenesis

Core molecular disintegration stage. Prepared feedstock enters the Recyclotron Multiphase Microwave Reactor, where Microwave Catalytic Reforming at 650°C+ in an anoxic (oxygen-free) environment breaks material to its molecular level — no combustion, no flame, no ash. At 1,200°C+ processing temperatures, carbon-fluorine bonds (PFAS) are broken to atomic elements. Primary output: OmniCrude™ — an elementally rich intermediate state containing all carbon, hydrogen, metals, and rare earth elements liberated from incoming feedstock.

Core Conversion

Regenesis MAX

Advanced materials refining stage. OmniCrude™ — the defined intermediate product of Regenesis — enters selective refining: carbon product refinement (activation at 1,800°C, graphitisation at 3,000°C producing EcoGraph™ synthetic graphite), hydrocarbon cracking, hydrogen separation, metals purification, rare earth extraction, glass refinement, aromatics separation, and water recovery. OmniCrude™ is not a residual — it is the manufactured input to this refining stage.

High-Value Upgrading

RevCon™ = Total Material Conversion

The complete ACM system — all four protocols integrated. Designed for near-100% material conversion: inputs become manufactured products. No ash, no Liquifact, no residual for disposal. Nine manufactured product streams from a single feedstock input.

Complete System

ACM RevCon™ 3 Product Suite — Nine Manufactured Output Streams

Manufactured Product	Yield (% of input)	Business Baseline Price/ton	Revenue at 400 TPD (full cap.)	Application
Renewable Graphite (EcoGraph™)	13%	$3,750/ton	~$77.0M/yr	Battery anodes, steel manufacturing, lubricants — largest single product revenue stream
Renewable Advanced Carbon Products	2%	$5,000/ton	~$15.8M/yr	Aerospace composites, carbon fiber precursors, specialty industrial applications
Renewable Refined Water (DI)	24%	$250/ton	~$9.5M/yr	Deionized water for industrial processes; significant value in Phoenix's water-scarce environment
Renewable Industrial Gases	16%	$250/ton	~$8.5M/yr	Industrial gas markets; syngas applications; chemical feedstocks
Renewable Aromatics	8%	$450/ton	~$3.8M/yr	Benzene, toluene, xylene equivalents; chemical industry feedstocks
Renewable Metals	6%	$375/ton	~$1.9M/yr	Ferrous and non-ferrous metal recovery; direct scrap market
Renewable Glass Aggregates	8%	$75/ton	~$0.8M/yr	Construction aggregates, road base, landfill cap material
Renewable Aggregates	13%	$13/ton	~$0.8M/yr	Construction fill, base course material
Renewable Hydrogen	10%	Captive — Island Mode	Designed to eliminate utility grid dependency — Island Mode via captive PEM hydrogen	Captive PEM fuel cells power the facility. No grid dependency. No utility cost line in P&L.
Total Product Revenue — 400 TPD Full Capacity			~$119.1M/yr	Plus TMC Fee revenue of ~$21.9M/yr = ~$141M total Year 2+

Operational Validation — This Is Not a Concept Carbotura has an executed government contract in Pennsylvania and advanced negotiations in Saudi Arabia representing approximately $7 billion in combined pipeline — sovereign-level procurement validation from two of the world's most scrutinised contracting environments. The first Carbotura modular factory is currently under construction with commercial operations targeted for 2027. Independent technical due diligence and third-party verification are openly invited and have been completed as part of these procurement processes. Phoenix is not evaluating a concept — it is evaluating a manufacturing system that is already being built.

For Council — "Is This Incineration?" Incineration burns material — it requires oxygen, produces a flame, generates ash that must be disposed of, and emits combustion gases requiring air quality controls. The ACM Recyclotron is the opposite: it operates in an anoxic (oxygen-free) environment, uses electromagnetic molecular reforming, produces no flame, generates no combustion ash, and is designed for near-zero stack emissions. Think of the difference between burning wood in a fireplace (combustion — requires oxygen, produces ash and emissions) versus a refinery that disassembles crude oil into gasoline, chemicals, and industrial gases through catalytic reforming without burning anything. Phoenix's feedstock goes into the Recyclotron as mixed material and comes out as nine manufactured products. Nothing is burned. Nothing is landfilled from the ACM stream.

TMC Fee Derivation — Source: Phoenix Metro Waste Intelligence Report 2025, s12

Stream	Net Cost ($/ton)	Est. Volume Share	Weighted Contribution
Residential MSW Collection	$240/ton	55%	$132.00
Landfill Disposal — MSW	$52/ton	20%	$10.40

C&D Waste	$47/ton	3%	$1.41
Full-Weighted Disposal Cost (FWDC) — Source: s12 Regional Average			~$153.71/ton

Step 1 — FWDC: $153.71/ton (volume-weighted average, s12 regional, equal-weighting applied where per-stream tonnage data unavailable)

Step 2 — TMC Fee Formula: MAX($100, MIN($150, FWDC − $5)) = MAX($100, MIN($150, $153.71 − $5)) = MAX($100, MIN($150, $148.71)) = $148.71 → $150/ton (ceiling applied)

Step 3 — Ceiling Rule: FWDC of $153.71 places TMC Fee at the $150 ceiling. TMC Fee = $150/ton

Step 4 — Floor Check: FWDC ($153.71) > $105 → floor does not apply. TMC Fee is at ceiling = $150. Same value across all three tiers. Escalates 1%/yr from Year 1.

TMC Fee is pinned at $150/ton for this document. Source: s12 regional average. Actual TMC Fee will be confirmed in the Term Sheet based on verified community-specific cost data at time of engagement.

For Council — The Community's Role in ACM Phoenix's role is simple: deliver manufacturing feedstock to the RIC facility and receive payment. That's it. Carbotura handles the capital, the construction, the permitting, the operations, the product sales, and the environmental obligations. Phoenix pays the TMC Fee ($150/ton) just as it currently pays disposal fees — except this one is $4 less per ton than Phoenix's current cost, and it comes with a Circular Royalty™ payment from Year 2 that is projected to exceed what Phoenix pays in TMC Fees each year. The relationship is not a utility contract or a landfill extension. It is a manufacturing supply arrangement where Phoenix is the feedstock supplier and Carbotura is the manufacturer.

For Finance — COA Structure & Budget Treatment Circular Offtake Agreement (COA): The governing instrument is a 30-year COA between the City of Phoenix and Carbotura Inc. — not a lease, not a bond issuance, not a capital commitment. Under GASB 60, it is a service concession arrangement: Carbotura provides capital and operations; Phoenix provides feedstock access and COA commitment. Budget line: TMC Fee replaces the current disposal contract line in the Public Works operating budget — same line, lower cost per ton, same GASB 62 operating expenditure classification. Royalty receipt: Circular Royalty™ is recognized under GASB 33 as non-exchange operating revenue — credited annually to the enterprise fund or General Revenues depending on Phoenix's fund accounting structure. No bonds, no capital budget allocation, no debt service.

Proposal

P2 Three-Tier Build Plan

The proposed ACM facility at the Resource Innovation Campus (RIC), 27th Avenue corridor, is designed to serve Phoenix's manufacturing feedstock management needs across three configurable tiers — all sharing a single 1,000 TPD building shell constructed in Phase 1. Each tier is independently operable. Each tier expands from the prior tier through module addition only.

One Shell, Three Configurations Regardless of which tier Phoenix selects at the Term Sheet stage, the building shell is always constructed to 1,000 TPD capacity. This means the civil engineering, foundation work, utility connections, and primary structure are built once — in Phase 1 — before Module 1 activates. All subsequent module additions (whether expanding from 400 to 1,400 TPD, or from 1,400 to 2,000 TPD) are module installations inside the existing shell. No new site work. No new permitting. No new community impact review. Expansion notice period: 6 months.

For Council — Why Tier 1 Is Not Just a Bigger Minimum "Can't we just start small and expand later?" You can — and the Minimum configuration is a real, complete option. But the financial logic of Tier 1 isn't just proportional scaling. The building shell costs the same whether you put 4 modules in it or 14. The civil engineering, land preparation, utility connections, and primary structure represent the same fixed cost base. When you add 10 more modules to that existing shell, you're adding $550M of revenue capacity on top of an already-amortized civil foundation. The result: the 30-year combined community benefit grows from $1.96B (400 TPD) to $6.86B (1,400 TPD) — not 3.5× the benefit for 3.5× the size, but a non-linear increase because the fixed costs are spread across far more throughput. Phoenix generates 1 million tons per year. The Minimum tier processes 146,000 of those tons. Tier 1 processes 511,000. The question is how much of your own manufacturing feedstock you want generating a Circular Royalty™.

P4 Community Returns — 30-Year Projection

The 30-year community return has two components: the Circular Royalty™ (paid by Carbotura to Phoenix annually from Year 2) and the Avoided Disposal Cost (the value of not paying the current FWDC, which escalates at 5.9%/year). Both compound over time. The combination produces a total community benefit that grows every year for 30 years.

Cumulative combined benefit = sum of (Avoided Cost − TMC Paid + Circular Royalty™) for all years to date. Uses staged tons and FWDC $154/ton escalating 5.9%/yr. Royalty = 1.20 × TMC Fee escalating 1%/yr. Illustrative projections — not contractual commitments.

Cumulative 30-Year Community Benefit — Three Tiers

Illustrative projections — cumulative community benefit (Circular Royalty™ + Avoided Disposal Cost − TMC Fee). Year 2 crossover on all tiers. Compounding effect of 5.9%/yr disposal escalation vs. 1%/yr TMC Fee escalation drives the growing gap over 30 years. Not contractual commitments.

The Compounding Advantage — Two Escalators Moving in Opposite Directions The 30-year community return doesn't just add up linearly — it accelerates. Two forces compound simultaneously: the Circular Royalty™ escalates at 1% per year, while the disposal cost Phoenix would otherwise be paying escalates at 5.9% per year. The gap between what Phoenix pays (TMC Fee, slow growth) and what Phoenix receives (royalty + avoided cost, fast growth) widens every single year. By Year 30, Phoenix is projected to be paying approximately $265/ton in TMC Fee while avoiding a disposal cost that would have reached over $860/ton. The avoided cost advantage alone exceeds $600/ton by Year 30. Over 30 years, this compounding dynamic produces projected combined benefits of $1.96B, $6.86B, and $9.80B — not because of any guarantee, but because of arithmetic applied to a 5.9% cost escalation rate that the Phoenix Waste Intelligence Report documents as the structural baseline.

For Council — The Year 2 Crossover Point "Why does it take until Year 2?" The Circular Royalty™ has a 13-month lag — it's calculated on the prior year's TMC Fee payments and delivered 13 months after operations begin. This is the time Carbotura needs to confirm throughput, calculate the royalty amount, and process the payment. Think of it like a landlord-tenant relationship where the first year's deposit earns interest: you don't receive the interest on Day 1, but you receive it annually from Year 2 onward, and it is defined by the COA. Under the proposed agreement, the Circular Royalty™ payment is calculated annually based on the prior year's verified TMC Fee receipts — a contractual obligation Carbotura owes to Phoenix, not a discretionary rebate.

Proposal

P5 Next Steps

This document is a Stage 1 Partnership Proposal. No commitment has been made by either party. The following three steps initiate the formal engagement process leading from this proposal to a Circular Offtake Agreement and operational ACM facility at the Resource Innovation Campus.

Step 1 — Execute a Letter of Intent (LOI)

The City of Phoenix submits a Letter of Intent to Carbotura Inc. confirming interest in advancing the proposed partnership. The LOI is non-binding and initiates the formal due diligence and Term Sheet process. No financial commitment is made by Phoenix at this stage. The LOI confirms that both parties are engaged in good-faith discussion of the proposed ACM deployment at the Resource Innovation Campus.

Step 2 — Schedule a Site Assessment Meeting

Carbotura's technical and development team conducts an on-site assessment of Phoenix's manufacturing feedstock generation, logistics, and the proposed RIC facility location. This informs the final Term Sheet parameters including which tier configuration is most appropriate for Phoenix's current and projected feedstock volumes, the specific logistics configuration for the 27th Avenue corridor, and the commissioning schedule relative to the Q2 2027 target COD.

Step 3 — Request and Negotiate a Term Sheet

Carbotura issues a formal Term Sheet outlining the proposed configuration tier, TMC Fee, Circular Royalty™ schedule, CAPEX commitment, and commissioning timeline. Execution of the Term Sheet advances the parties to COA drafting. The Term Sheet also includes the throughput guarantee structure, force majeure provisions, and performance milestone framework that will govern the full COA.

Proposed COA Key Terms — Summary

Term	Proposed Structure
Agreement Type	Circular Offtake Agreement (COA) — not a lease, not a bond, not a public-private partnership in the traditional sense
Term	30 years from COD of Module 1
Facility Ownership	Carbotura Inc. owns the facility for the full term. Phoenix owns the RIC land. Site access governed by ground lease or access agreement within COA.
Capital Contribution	$0 from City of Phoenix. 100% Carbotura-financed via SPV (Special Purpose Vehicle) established for the Phoenix deployment.
TMC Fee	$150/ton (confirmed at Term Sheet stage from community-specific cost verification). Escalates 1%/year from Year 1. Operating expenditure — not debt.
Circular Royalty™	120% of prior-year TMC Fee receipts. Paid annually. Begins Year 2 (13-month lag). Escalates 1%/year. Recognized as operating revenue under GASB 33.
Title Transfer	Manufacturing feedstock title transfers to Carbotura at facility receipt. Phoenix no longer responsible party from that point under RCRA, CERCLA, or ADEQ permitting.
Permits	All environmental and manufacturing permits held by Carbotura Inc. Phoenix is not the permit holder. NAICS 325xxx/331xxx manufacturing permit — not solid waste facility plan.
Throughput	Minimum throughput guarantee and performance milestones defined in Term Sheet. Force majeure provisions included.
SPV Structure	Carbotura establishes a Phoenix-specific Special Purpose Vehicle for the deployment. SPV holds facility permits, COA rights, and capital. Isolates Phoenix ACM operations from Carbotura's broader portfolio.

Requesting Undisclosed Information — Model Public Records Templates

Several key figures in this report are drawn from publicly available data, but certain critical documents are not publicly disclosed by Phoenix or its operators. The following are model Arizona Public Records Act requests (ARS §39-121) that Phoenix officials, council members, or community organisations can submit to obtain the underlying data.

Document Sought	Why It Matters	Submit To	ARS §39-121 Request Language
SR-85 Landfill remaining capacity and projected closure date	Closure timeline is not publicly disclosed. This is the primary capacity risk variable in Phoenix's disposal planning.	City of Phoenix Public Works Department — Records Division	"Pursuant to ARS §39-121, I request all records relating to: (1) the current remaining permitted airspace at the SR-85 Landfill, Buckeye AZ; (2) the projected closure date or capacity exhaustion date; (3) any engineering assessments or cell-by-cell capacity reports produced in the last five years."
Phoenix Water PFAS biosolids testing results and management plan	ADEQ confirmed PFAS in Arizona biosolids; Phoenix Water's NPDES permit expires April 2028. No management plan is publicly disclosed.	City of Phoenix Water Services Department — Records Division	"Pursuant to ARS §39-121, I request all records relating to: (1) PFAS testing results for biosolids produced at the 91st Avenue WWTP; (2) any PFAS biosolids management plan, risk assessment, or compliance strategy; (3) any correspondence with EPA, ADEQ, or Synagro Technologies regarding PFAS in biosolids."
SR-85 Landfill closure and post-closure financial assurance documents	Closure reserve is embedded in the capital plan without separate disclosure. ADEQ financial assurance requirements may lag actual closure costs.	ADEQ Waste Programs Division — Public Records	"Pursuant to ARS §39-121, I request all financial assurance documents filed by the City of Phoenix for the SR-85 Municipal Solid Waste Landfill, including current assurance amounts, mechanism type, and the most recent independent closure cost estimate submitted to ADEQ."
City of Phoenix enterprise fund five-year financial forecast	This report identifies a $20.8M structural shortfall in FY2025–26 and projects near-zero reserves by FY2027–28. The detailed forecast documentation underpins these figures.	City of Phoenix Budget and Research Department	"Pursuant to ARS §39-121, I request the most recent five-year financial forecast and reserve projection for the City of Phoenix Solid Waste Enterprise Fund, including any actuarial or cost-escalation analysis prepared by or for the City."

Navigating the Transition

A — Council Q&A: Anticipated Questions

"Is this incineration?"

No. The Recyclotron operates without combustion in an anoxic environment — no flame, no ash, no combustion stack emissions. Only a manufacturing air quality permit is required. The outputs are engineered manufactured products, not combustion residue.

"We have existing contracts with Republic and WM."

The COA is structured to begin at contract expiry or as a supplement to existing contracts. No breach is required. The transition is mapped in the Term Sheet. Given the 30-year COA term, planning begins now regardless of current contract calendar.

"Is this technology proven?"

The ACM system integrates 35+ commercially established component technologies. The engineering innovation is the AI-optimized integration architecture — not novel chemistry. The component technologies operate in industrial settings globally. This is systems integration, not a laboratory experiment.

"What are our environmental and regulatory risks?"

Under the COA, title transfers at feedstock receipt — Phoenix is no longer the responsible party for that material. All permits are Carbotura's. The manufacturing permit (NAICS 325xxx/331xxx) carries none of the post-closure, financial assurance, or groundwater monitoring obligations of a solid waste facility permit.

"What if projections don't materialize?"

The pre-COA projections are illustrative. The COA defines performance milestones, throughput guarantees, and force majeure. Phoenix's financial exposure equals the TMC Fee only — already paid in equivalent form to Republic and WM. The Circular Royalty™ is upside, not a dependency.

"Why pay a TMC Fee when we already pay disposal fees?"

You already do pay — this one pays you back. The TMC Fee of $150/ton is $4 less than Phoenix's current blended disposal cost. Year 2 Circular Royalty™ equals 120% of every dollar paid. Same expenditure — restructured to return $1.96B–$9.80B to Phoenix over 30 years depending on tier selection.

"What is Phoenix's total financial exposure?"

TMC Fee only — an operating expenditure equivalent to current disposal contracts. Zero capital commitment. No bonds, no leases, no environmental bonds, no post-closure obligations. Under GASB 62/87: operating line, not debt. Phoenix's maximum downside is replacing an existing disposal contract with a slightly cheaper one.

B — Incumbent Pushback Tactics

Market Context — What Transition Signals to Incumbents Phoenix's two primary disposal operators — Republic Services and Waste Management — collectively serve an estimated $150M–$200M+ in Phoenix-area disposal volume annually. A Tier 1 ACM deployment at 511,000 tons/year would represent a material shift in how approximately half of that volume is managed. This is not a criticism of incumbent operators — both are professionally run companies responding rationally to their market structure. It is context for why Phoenix should expect counter-proposals, rate adjustments, and questions about ACM technology when it signals interest in the partnership. Carbotura's response to any counter-proposal is straightforward: require it to include 30-year modelled costs, post-closure obligation assignment, and PFAS indemnification language. The comparison speaks for itself.

Tactic	How It Presents	Reality	Rebuttal
"Technology unproven"	Requests for operating references, comparisons to failed gasification projects, technology risk framing	Component technologies are individually proven; integration is the question. ACM is not gasification in the traditional sense.	Request performance guarantees in writing in the Term Sheet. Compare 30-yr COA risk vs. 30-yr landfill extension risk (closure, PFAS, FA gap).
"We can offer a better deal"	Rate concessions or contract sweeteners timed to Phoenix's LOI submission	Confirms the existing rate was negotiable and uncompetitive. The concession is a market response to competitive threat, not a permanent pricing change.	Require any counter-proposal to include 30-year modeled costs, post-closure obligation assignment, and PFAS indemnification language.
"Regulatory uncertainty"	Permitting risk claims; claims ACM requires solid waste facility permit	Arizona SB 1156 (2021) established the manufacturing permit pathway explicitly. NAICS 325/331 = manufacturing, not NAICS 562 waste.	Request legal opinion in writing on SB 1156 applicability. Review ADEQ's advanced recycling guidance documentation.
"Job losses in current operations"	References to incumbent workforce at Phoenix facilities	ACM creates 156–780 manufacturing jobs at $110,000 average salary vs. waste sector average of $45,000–$65,000. Net employment upgrade for any transitioning workers.	Request actual local Phoenix employment data from incumbent contracts. Compare job quality, wage levels, and benefit structures.
"Timeline risk"	Construction delay scenarios; claims Q2 2027 COD is unrealistic	Modular construction from a pre-built shell. Module addition is the variable, not civil construction. The 1,000 TPD shell is the critical path item — built once.	Review incumbent operators' own track records on contract delivery and landfill construction timelines in Arizona.

C — The Legacy Cost Trajectory — What Inaction Costs

Phoenix currently processes approximately 146,000 tons per year in the 400 TPD equivalent stream at a blended cost of ~$154/ton — an annual expenditure of approximately $22.5 million generating zero financial return. At 5.9% annual escalation, that annual expenditure reaches $37.7 million by Year 10, $66.9 million by Year 20, and $118.7 million by Year 30. The enterprise fund is already in structural deficit at current cost levels. Every year of inaction compounds that deficit.

Year	Legacy $/ton	Annual Spend (400 TPD stream)	ACM TMC Fee	Net Saving vs. Legacy
Year 1	$154	$22.5M	$150	+$0.6M saving
Year 5	$194	$28.3M	$156	+$5.5M saving
Year 10	$258	$37.7M	$164	+$13.7M saving
Year 20	$458	$66.9M	$181	+$40.5M saving
Year 30	$812	$118.6M	$199	+$88.8M saving

Illustrative projections — 400 TPD stream. Legacy cost = $154 escalating 5.9%/yr. ACM TMC Fee = $150 escalating 1%/yr. Net saving = TMC Fee outflow only vs. legacy disposal cost; does not include Circular Royalty™ inflow or avoided cost value.

D — Talking Points for Council & Community

Against the legacy cost escalation: "Phoenix has been paying to dispose of manufacturing feedstock for decades — and that cost is going up 5.9% a year automatically, without any decision required. By 2030, the same ton will cost $274 to process instead of $154 today. The ACM partnership is the only available mechanism that locks our cost below current rates while generating a return."

For ACM: "The proposed ACM facility at the RIC creates 546 manufacturing jobs at $110,000 average salary, processes 51% of our annual manufacturing feedstock, generates a projected $6.86 billion in 30-year community benefit, and costs Phoenix zero dollars in capital. We're not being asked to build anything. We're being asked to supply raw material to a factory that pays us back."

10 questions for any alternative vendor: (1) What is your 30-year modeled cost per ton including post-closure, PFAS remediation, and financial assurance escalation? (2) What is your PFAS indemnification commitment? (3) What happens when SR-85 closes? (4) How does your proposal improve our enterprise fund operating surplus? (5) What manufacturing jobs does your proposal create in Phoenix? (6) What is your Circular Royalty equivalent? (7) Do you hold your own environmental permits or does Phoenix remain the responsible party? (8) What is your Year 30 per-ton cost? (9) How does your proposal contribute to Reimagine Phoenix 50% diversion by 2030? (10) What is Phoenix's capital requirement?

The Transformation Narrative — Same Expenditure, Restructured Phoenix has always paid to manage its manufacturing feedstock. That expenditure has historically flowed to disposal vendors, generating no return, accumulating liabilities, and growing at 5.9% per year. The proposed Carbotura partnership transforms that expenditure into an investment: returning 120% as a Circular Royalty™, creating 546 direct manufacturing jobs, contributing to the Reimagine Phoenix 50%-by-2030 diversion goal, and eliminating forward liability exposure for the ACM-processed stream. Same expenditure. Restructured to benefit the City of Phoenix.

Public & Resident Impact

P4b Public & Resident Impact

Every economic benefit in this proposal ultimately flows through Phoenix's 1,673,164 residents. This section translates the city-level financial benefits into concrete, resident-facing outcomes: lower structural pressure on utility rates, relief from the enterprise fund crisis, PFAS and CCR liability protection, and additional diversion capacity. It also surfaces the real accountability routes available to residents and rate-payers, and identifies the upcoming decision points where public engagement can most effectively influence outcomes.

The Enterprise Fund Crisis — What It Means for Rate-Payers

Phoenix Public Works is carrying a confirmed $20.8M structural shortfall into FY2025–26. The proposed remedy is a 45% residential rate increase phased over three years — roughly $130–$175 in additional annual charges per household. This is not a one-time adjustment: at 5.9% annual cost escalation, the rate increase buys perhaps three years of structural balance before the same gap reopens. The ACM partnership changes this dynamic fundamentally.

Scenario	Resident Rate Impact	Enterprise Fund Position FY2028	Structural Fix?
Status Quo + Rate Increase	+$130–175/household/year (proposed 45% increase, 3-yr phase)	~Break-even by FY2028; gap reopens FY2029+ as costs compound 5.9%/yr	NO — TEMPORARY
ACM Partnership (400 TPD minimum)	TMC Fee cost locked below current $154/ton; rate increase pressure reduced by $0.4M Year 1, growing annually	Circular Royalty™ inflow begins Year 2 (+$16.4M/yr) — directly improves enterprise fund structural balance	YES — STRUCTURAL
ACM Partnership (1,400 TPD)	$78.7M/yr TMC Fee replaces escalating disposal cost; enterprise fund Circular Royalty™ inflow $99.3M/yr by Year 10	Structural surplus achievable by Year 3; rate freeze possible	YES — TRANSFORMATIVE

✓ The Rate-Payer Case in One Sentence Every dollar Carbotura pays Phoenix as a Circular Royalty™ is a dollar that does not need to come from a residential utility bill. The proposed partnership does not eliminate the enterprise fund deficit overnight — but it changes the trajectory from "rates must rise indefinitely to cover rising disposal costs" to "disposal costs are locked at 1%/yr growth and a new revenue stream is arriving."

PFAS & CCR Risk — What Residents Are Currently Exposed To

Phoenix residents bear the ultimate liability exposure documented in SQ3. PFAS contamination from biosolids land application in Maricopa County is an ongoing and unresolved risk; regulatory enforcement is accelerating under EPA's April 2024 MCL rules. Coal combustion residuals (CCR) from APS Cholla and Navajo plants create groundwater monitoring obligations that, if enforcement escalates, will translate into rate surcharges. These are not abstract risks — they are contingent liabilities accruing against public balance sheets that residents ultimately guarantee.

Liability Category	Estimated Exposure	Resident Impact (÷ 618,000 households)	ACM Effect
PFAS / Biosolids (Synagro)	$50M–$200M+	$81–$324 per household (contingent)	ACM title transfer removes Phoenix from permit-holder position for ACM-processed biosolids fraction; eliminates forward accrual for converted streams
CCR — APS/SRP coal ash	$50M–$500M+	$81–$810 per household (contingent)	ACM does not directly address CCR, but eliminates new post-closure obligations for ACM-converted feedstock streams
WQARF / Superfund legacy	$500M–$1B+	$810–$1,620 per household (contingent)	ACM feedstock has no new site creation — no landfill expansion, no new cell development, no new leachate generating area
COPERS Pension Deficit	$1.32B (74.65% funded)	$2,136 per household (existing obligation)	Not directly addressed by ACM; Circular Royalty™ revenue improves general fund capacity to fund pension contributions
Total Contingent Exposure	$2B+	$3,236+ per household	ACM eliminates new accrual for converted stream; reduces forward liability growth

Collection Service Impact — What Changes for Residents

Service Area	Current Status	Under ACM Partnership	Resident Change
Residual (black bin) collection	Weekly collection; escalating per-ton cost; 45% rate increase proposed	Residual stream feeds ACM as manufacturing feedstock; TMC Fee locked at $150/ton escalating 1%/yr	No collection change; structural rate pressure removed from disposal cost side
Recycling (Balcones MRF)	27th Ave MRF; 10-yr $158M Balcones contract; contamination risk at 115°F	MRF continues; ACM accepts contaminated loads MRF rejects — reduces contamination write-off volumes	Potential to reduce sorting burden as ACM handles borderline-contaminated loads that MRF currently rejects
Organics / Compost	27th Ave compost facility; WeCare Denali contract; proposed fee increase risks enrollment drop	ACM accepts organic fraction as manufacturing feedstock if organics program contracts; no resident-facing service gap	Service continuity regardless of organics program fate; ACM provides backup capacity
Diversion Rate	~36% actual; 50% by 2030 target; no programmatic pathway under current law	ACM feedstock removed from solid waste stream by statute at delivery (SB 1156 2021); counts toward diversion without voluntary program dependency	1,400 TPD configuration alone contributes ~31 percentage points toward 50% target — achieves Reimagine Phoenix without behavioral change requirement

The 50% Diversion Target — Solved Without a Mandate Phoenix's Reimagine Phoenix 50%-by-2030 diversion target has no identified pathway under current Arizona preemption law. Mandatory commercial recycling, organic waste diversion mandates, pay-as-you-throw pricing — all preempted by ARS §9-500.38 and related statutes. The one legislative opening that exists is SB 1156 (2021): advanced recycling as manufacturing. Under SB 1156, ACM feedstock is reclassified as manufacturing input at the moment of delivery — not at the landfill gate, not contingent on resident sorting behavior. A 1,400 TPD ACM facility processes 511,000 tons/year, contributing approximately 31 percentage points toward the 50% target, entirely through a manufacturing permit, not a recycling program. Residents do not need to change behavior for this diversion to count.

Talking Points for Council & Community Communication

💬 "We're not increasing the disposal budget — we're restructuring it." Phoenix is already spending $22.5M per year on the 400 TPD manufacturing feedstock stream. The ACM TMC Fee is $150/ton — $4 below current cost from Day 1. We're replacing a rising cost with a near-flat one, and adding a Circular Royalty™ return from Year 2. Same expenditure. Different trajectory.

💬 "ACM is not incineration. It operates under a manufacturing permit." Under Arizona SB 1156 (2021), the ACM facility operates under a manufacturing permit — NAICS 325xxx/331xxx — not a solid waste facility permit. ADEQ does not regulate it as a waste facility. It is a manufacturing plant that receives raw material and produces nine categories of saleable manufactured products.

💬 "Phoenix doesn't fund this. Carbotura does." Zero capital from the City of Phoenix. No general obligation bond. No enterprise fund capital draw. No new tax. Carbotura finances, builds, owns, and operates the facility entirely at its own cost. Phoenix supplies manufacturing feedstock and receives a Circular Royalty™.

💬 "The PFAS liability stops accruing for the streams we convert." Every ton of manufacturing feedstock that goes to the ACM facility is a ton that is no longer Phoenix's environmental liability. Title transfers at the gate. Phoenix's forward PFAS exposure stops growing for that material on the day it is delivered to Carbotura.

💬 "780 manufacturing jobs at $110,000 average salary — not waste jobs." ACM classifies under NAICS 325xxx/331xxx manufacturing codes — the same sector as Phoenix's semiconductor and advanced manufacturing corridor. The 780 Tier 2 positions at $85.8M annual payroll represent a manufacturing employment base, not a waste management service extension.

💬 "The rate increase buys three years. ACM buys thirty." The proposed 45% rate increase resolves the enterprise fund deficit temporarily — until disposal costs compound to the new baseline and the gap reopens. The ACM TMC Fee is contractually locked at 1%/yr for 30 years. The Circular Royalty™ grows with the TMC Fee. The structural fix is permanent, not a three-year patch.

⚠ Time Is the Critical Variable Phoenix's $20.8M enterprise fund shortfall is already confirmed for FY2025–26. The SR-85 Landfill closure timeline is not publicly disclosed — but the cell development capital ($9M) in the five-year plan indicates a constrained remaining life. The ACM construction period is 18 months. A Q2 2027 COD for the minimum 400 TPD configuration requires ground break no later than Q4 2025 — meaning a Letter of Intent should be executed by Q2 2025. Every quarter of delay is a quarter in which the status quo disposal cost compounds at 5.9%, the enterprise fund deficit deepens, and the Circular Royalty™ start date recedes.

Appendix

E ACM Glossary — Authoritative Terminology

All terms below are per Carbotura ACM Industry Nomenclature Proofing Guide v3.7. These definitions are the authoritative reference for all terminology used throughout this document. Usage of any legacy solid waste sector terminology to describe ACM processes, products, or outputs is incorrect and should be replaced with the definitions below.

Term	Definition	Replaces / Contrasted With
Advanced Circular Manufacturing (ACM)	The complete system of receiving, processing, and converting manufacturing feedstock into a portfolio of renewable manufactured products using the Total Material Conversion (TMC) protocol. ACM operates as a manufacturing sector activity under NAICS 325xxx/331xxx, not as a waste management operation under NAICS 562.	Replaces: waste-to-energy, gasification, incineration, advanced recycling (in lay usage). ACM is manufacturing — not energy recovery, thermal treatment, or solid waste disposal.
Circular Offtake Agreement (COA)	The governing 30-year contract between Carbotura Inc. (or its designated SPV) and the host community. The COA defines the TMC Fee, Circular Royalty™ schedule, title transfer mechanism, throughput guarantees, performance milestones, force majeure provisions, and commissioning timeline. Not a lease, bond, utility agreement, or solid waste disposal contract.	Replaces: disposal contract, landfill agreement, hauling contract, service concession agreement (though treated as such under GASB 60).
Circular Royalty™	Carbotura's annual payment to the host community under the COA. Equal to 120% of the prior year's TMC Fee receipts. Escalates at 1% per year for the full COA term. Payable annually, beginning 13 months after first delivery (Year 2). Recognized as operating revenue under GASB 33 (US), PSAB PS 3400 (Canada), IFRS 15 (international), or applicable jurisdiction standard.	Not: a rebate, discount, credit, or incentive. A separate cash payment. Revenue, not a reduction in expenditure.
EcoGraph™	Carbotura's branded renewable graphite product — the primary revenue-generating output stream of the ACM RevCon™ 3 protocol. Derived from the carbon fraction of manufacturing feedstock through the Regenesis MAX stage. Yield: approximately 13% of input mass. Application: battery anodes, steel manufacturing, lubricants, specialty industrial.	Not: a recycled material, a recovered material, a byproduct, or a residue. EcoGraph™ is a manufactured product meeting industrial grade specifications.
Exogenesis	The ACM protocol for processing legacy contaminated materials — including legacy site remediation materials, legacy landfill content, and legacy contaminated soil — as a supplemental manufacturing feedstock stream. Converts remediation obligations into revenue-generating manufacturing inputs. Subject to site-specific feasibility assessment.	Not: remediation, cleanup, or waste processing. Exogenesis is the re-introduction of legacy materials into the manufacturing feedstock supply chain.
Feedstock Haulers	Third-party logistics providers responsible for transporting manufacturing feedstock from collection points (transfer stations, generator locations) to the ACM facility. Feedstock Haulers operate under contracts with either Carbotura or the host community, as defined in the COA. Their role is logistics, not waste collection or disposal.	Not: waste haulers, garbage collectors, or disposal contractors. Feedstock Haulers are logistics service providers in the manufacturing supply chain.
Liquifact	The proprietary term for any liquid effluent generated within the ACM process envelope. In the RevCon™ 3 configuration, Liquifact generation from ACM-processed manufacturing feedstock is designed to be zero — all liquid fractions are either recovered as Renewable Refined Water (DI) or returned to process. Distinguished from landfill leachate, which is Liquifact generated by the biodegradation of material in a landfill environment — a process absent from ACM operations.	Not: leachate, wastewater, effluent, or discharge. The term Liquifact is used where liquid generation must be referenced; the design intent is zero Liquifact from ACM-processed feedstock.
Manufacturing Feedstock	The primary input material for the ACM process — material that would otherwise be directed to landfill disposal, transfer station, or alternative disposal pathway. Manufacturing feedstock includes MSW (mixed manufacturing feedstock), organic fractions, construction and demolition material, biosolids, and tire-derived material accepted under the ACM facility's manufacturing permit. Manufacturing feedstock is a raw material, not a waste product, from the moment it enters the ACM supply chain.	Replaces: waste, garbage, refuse, solid waste, municipal solid waste (MSW), trash, rubbish. After SB 1156 (Arizona 2021), manufacturing feedstock delivered to a qualifying thermochemical processor is reclassified as a manufacturing input by statute.
Molecular Reforming	The core ACM conversion mechanism — the application of electromagnetic energy in an anoxic (oxygen-free) environment to break and reform molecular bonds in manufacturing feedstock, converting complex mixed-material inputs into discrete manufactured output streams. Distinguished from combustion (which requires oxygen and produces ash and stack gases), gasification (which operates at high temperature with a controlled oxygen environment and produces syngas), and pyrolysis (which uses thermal degradation in the absence of oxygen but typically yields a narrower product suite than ACM).	Replaces: burning, incineration, combustion, gasification, pyrolysis (in lay usage). Molecular reforming is neither thermal destruction nor combustion. It is a manufacturing process yielding saleable products.
OmniCrude™	Carbotura's branded renewable synthetic crude oil product — derived from the hydrocarbon fraction of manufacturing feedstock through the RevCon™ 3 protocol. Functions as a feedstock for conventional petroleum refining infrastructure. Not produced in the Phoenix configuration (captive PEM hydrogen configuration prioritizes EcoGraph™ and industrial gas outputs over OmniCrude™). Available as an output configuration option in alternative deployment specifications.	Not: recovered oil, pyrolysis oil, or fuel oil. OmniCrude™ is a manufactured synthetic crude meeting refinery feedstock specifications.
Pregenesis	The first of the four ACM protocols — intake, characterization, sorting, and preparation of manufacturing feedstock for subsequent processing stages. Pregenesis uses automated optical sorting, AI-guided characterization, and mechanical preparation to establish feedstock specification for Regenesis. Pregenesis does not convert material — it prepares material for conversion.	Not: sorting, recycling, material recovery, or pre-processing in the traditional MRF sense. Pregenesis is the intake protocol of a manufacturing process.
Recyclotron	Carbotura's proprietary name for the complete ACM manufacturing system — the integrated combination of Pregenesis, Regenesis, Regenesis MAX, and RevCon™ protocols operating as a single facility-scale manufacturing unit. The Recyclotron operates without combustion, is designed to produce no combustion ash, and recovers Liquifact as Renewable Refined Water rather than discharging it. One Recyclotron unit = one ACM facility deployment.	Not: an incinerator, a gasifier, a pyrolysis unit, a waste facility, or a materials recovery facility. The Recyclotron is a manufacturing system.
Regenesis	The primary molecular reforming protocol within the ACM system. Operates in an anoxic environment using electromagnetic molecular reforming to convert prepared manufacturing feedstock into primary output streams: graphite precursors, aromatic fractions, industrial gas fractions, metallic materials, and mineral outputs. Regenesis is the core conversion stage — all product streams originate here.	Not: combustion, gasification, pyrolysis, or thermal treatment. Regenesis is a molecular conversion process, not a thermal destruction process.
Regenesis MAX	The secondary upgrading protocol within the ACM system. Processes Regenesis primary outputs through additional molecular transformation steps to achieve final product specifications for EcoGraph™ graphite grades and Renewable Advanced Carbon Products. Regenesis MAX is the value-enhancement stage — it converts primary output streams into finished manufactured products meeting industrial grade specifications.	Not: secondary processing, refining waste, or upgrading residuals. Regenesis MAX is a manufacturing quality control and product specification stage.
RevCon™	Total Material Conversion — the complete ACM operating protocol integrating all four stages (Pregenesis + Regenesis + Regenesis MAX + captive PEM energy system) into a single continuous manufacturing process. RevCon™ 3 is the current generation configuration, incorporating third-generation AI process optimization, captive PEM hydrogen for Island Mode operation, and a nine-product output suite. The "3" denotes the third major configuration release. RevCon™ is Carbotura's proprietary manufacturing protocol — not a technology category name.	Not: a waste treatment technology, an advanced recycling process (in the regulatory sense), or a thermal energy recovery system. RevCon™ is a manufacturing protocol producing nine saleable product streams from a single feedstock input.
Revenue Stack	The complete set of revenue streams generated by a Carbotura ACM facility under the RevCon™ 3 protocol. The Revenue Stack comprises: (1) TMC Fee receipts from the host community; (2) product sales revenues from nine manufactured output streams (EcoGraph™, Renewable Advanced Carbon Products, Renewable Refined Water (DI), Renewable Industrial Gases, Renewable Aromatics, Renewable Metals, Renewable Glass Aggregates, Renewable Aggregates, and captive hydrogen for Island Mode); (3) potential environmental credit revenues (§45Q, §45V, RINs, RECs, VCCs — labeled upside only, not in base case).	Not: disposal income, tipping fee income, or gate revenue. The Revenue Stack is a manufacturing enterprise revenue model, not a disposal service revenue model.
TMC Fee (Total Material Conversion Fee)	The per-ton fee paid by the host community to Carbotura under the COA for delivery and conversion of manufacturing feedstock. The TMC Fee is calculated using the formula: MAX($100, MIN($150, FWDC − $5)), where FWDC is the community's Full-Weighted Disposal Cost per ton. For Phoenix Metro, the TMC Fee is $150/ton (ceiling applied). The TMC Fee is an operating expenditure under GASB 62/87 — not a disposal fee, not a tipping fee, and not a capital commitment. The TMC Fee escalates at 1% per year from Year 1.	Replaces: tipping fee, disposal fee, gate fee, landfill fee. The TMC Fee is a manufacturing supply arrangement fee — the per-unit cost of converting feedstock — not a waste disposal fee. The distinction is both operational and regulatory (NAICS 325/331 vs. NAICS 562).
Total Material Conversion (TMC)	The design principle of Carbotura's ACM system: the conversion of 100% of manufacturing feedstock inputs into saleable manufactured outputs, with near-zero residual — designed for complete material recovery with no residual requiring disposal. In the RevCon™ 3 configuration, TMC is achieved through the complete integration of Pregenesis, Regenesis, Regenesis MAX, and captive PEM hydrogen protocols. No ash, no Liquifact, no residual from ACM-processed feedstock requiring disposal or further treatment.	Contrasted with: landfill disposal (100% residual), MRF processing (~25–40% residual to landfill), incineration (~15–25% ash residual), gasification (slag and tar residuals). TMC is the engineering target — zero disposal from the ACM input stream.

Terminology Guidance — Key Distinctions for Public Communication Three distinctions matter most for public and council communication: (1) ACM is not incineration — no combustion, no ash, no combustion stack emissions; manufacturing permit only. (2) The TMC Fee is not a tipping fee — it is a manufacturing supply arrangement fee that is lower than Phoenix's current disposal cost and generates a Circular Royalty™ return from Year 2. (3) Manufacturing feedstock is not waste — from the moment it is designated for delivery to the ACM facility, it is a raw material in a manufacturing supply chain, reclassified by Arizona SB 1156 (2021) as a manufacturing input.
