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.

What this package is

A complete Advanced Circular Manufacturing engagement package for San Diego County, California. Six documents covering feedstock diagnosis, transaction structure, economic impact, the action brief, community narrative, and the programme overview. One decision drives all six: Execute the LOI/MOU.

Three things this package establishes
  1. San Diego County’s only municipal landfill closes ~2031. Gregory Canyon is canceled. No conventional alternative exists. The county’s disposal infrastructure has no replacement on any planning horizon.
  2. ACM deployment under a 30-year Circular Supply Agreement converts rising disposal costs into a Circular Royalty™ income stream that exceeds the Beneficiation Fee from Year 2 onward, compounding to ~$1.09B over the CSA minimum term (ILLUSTRATIVE).
  3. Carbotura finances, builds, owns, and operates all ACM facilities. San Diego County contributes no capital. The LOI/MOU is the engagement-stage commitment instrument — it starts the clock.

The Decision Window

Miramar Landfill closes approximately 2031 — approximately 60 months from Q3 2026. LOI/MOU execution today places Phase Initial Commercial Operations Date ~33 months ahead of that closure. Every month of delay compresses that buffer. Execution does not forfeit optionality; delay does.

Royalty figures labeled ILLUSTRATIVE: computed under Release 28 canonical formula (multiplier on current-year escalated BF). Not contractual projections until Term Sheet execution.

Planning basis: All financial figures presented in this package are illustrative estimates derived from a locked Beneficiation Fee of $100/ton (Architect directive) and Carbotura standard parameters. Figures do not constitute contractual commitments. ESTIMATED values derive from CalRecycle public data and modeled cost trajectories. Contracted FWDC, site-specific data, and precise parcel selections are confirmed during the Term Sheet phase following LOI/MOU execution. Royalty figures computed under Release 28 canonical formula (multiplier on current-year escalated BF).
