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.
