What this document is

The entry point for Carbotura’s Circular Advantage engagement with Phoenix — the documents covering the feedstock system, the commercial structure, the economics, the decision and what it means for residents.

Three things this document says
  1. Phoenix is at a decision point: City Council gives direction on the multi-year solid waste rate adjustment in April 2026.
  2. Advanced Circular Manufacturing converts the residual stream into products under one agreement, with no the City capital committed.
  3. The engagement decision has to be taken while the option is still open — authorising later forecloses the earlier phases.

Engagement Path — Follow the Numbers

1 LOI / MOU engagement begins A non-binding Letter of Intent / Memorandum of Understanding. It opens the engagement, establishes the joint working group and data exchange, and carries no cost and no obligation for the community. Steps 1–5 are paper — typically 3–18 months in total.
2 Term Sheet verification & terms The verification phase. Feedstock streams, volumes, and the community’s disposal-cost basis (FWDC) are confirmed, the site is selected, and the per-tonne commercial terms are agreed before anything is signed long-term.
3 CSA execution = T0 The Circular Supply Agreement — a minimum 30-year supply contract with perpetual continuation. Execution starts the project clock (T0). It locks the Beneficiation Fee, the Circular Royalty™, the feedstock commitment, and site access.
4 Underwriting Carbotura-financed Carbotura arranges 100% of the facility financing under its Build-Own-Operate model. The community contributes zero capital and takes no construction or financing risk; an 18-month Parent Performance Guarantee backs all payment obligations.
5 Permitting manufacturing basis The facility is permitted as manufacturing (NAICS 31–33), never as waste processing. Both parties commit to the Regulatory Predicate Transition — the endpoint is categorical: manufacturing classification across all permitting, licensing and regulatory contexts.
6 Deployment build · 12–18 months The facility is manufactured and deployed in standardized 100 TPD modular increments rather than built as one-off construction — a 12–18 month build from CSA execution to commissioning.
7 COD & Royalties royalty +13mo after first fee Commercial Operations Date: the facility begins accepting feedstock. The Beneficiation Fee applies to delivered tonnage, and the first Circular Royalty™ payment follows 13 months after the first fee payment, then monthly, escalating every year.

⚠ Rate Direction Deadline — VERIFIED
April 2026
Phoenix City Council direction on multi-year solid waste rate adjustment. Authorizing Term Sheet phase verification before this date preserves the CSA as a structural alternative to rate escalation.
⚠ Rate Effective Date — VERIFIED
July 1, 2026
Proposed residential rate increase takes effect if adopted April 2026. Solid Waste Fund projected near zero by FY2027-28 without structural reform.

WHAT CHANGES
What Adopting Carbotura Changes
A plain-language tour of how a 30-year ACM commitment changes a community’s fiscal position, employment, and waste system structure. Generic illustrative figures.

Planning basis note: Financial projections in this document suite are based on a modeled full-system disposal cost of $105/ton and Carbotura standard contractual parameters. The transfer station gate rate of $55/ton is verified from public sources; all other cost components are estimated. A Term Sheet phase verification will produce audited figures. All projected fiscal positions are estimates and are not guarantees of performance. Deployment timeline reflects the Carbotura standard schedule; a project-specific schedule will be confirmed through Term Sheet phase verification.
