The Disposal Problem. Solved.

Disposal spending has always been a one-way cost. Carbotura changes that equation — permanently.

State A — Today
Every dollar spent on disposal
County pays per ton $95–$110/ton
County receives back $0
Return on disposal spend 0%
Net per ton −$95/ton
Pure cost. No return. Escalates 3%/yr.
State B — With Carbotura (Year 2+)
Every dollar of TMC Fee
County pays TMC Fee/ton $102.50/ton
County receives royalty/ton +$120.00/ton
Return on TMC spend 117%
Net per ton +$17.50/ton
Net grows to +$90.84/ton by Year 30.

The Circular Royalty = TMC Fee × 120% (escalating +1pp/year). The TMC Fee replaces what was previously lost disposal spending — and then returns more than it cost, 13 months later on a rolling monthly basis. Every $100 paid in Year 1 becomes $120 received in Month 13. Every $100 paid in Year 10 becomes $155.95 received 13 months later. At steady state, the Circular Royalty is designed to exceed the TMC Fee on a per-ton basis — turning a cost center into a revenue stream for 30 years.

Authorization deadline
Community Feasibility Study — Q3 2026
Authorizing the Community Feasibility Study by Q3 2026 is the only action required to hold Phase Initial COD of Q2 2028 and first Circular Royalty payment of July 2029. This is a structured analysis step — not a contract commitment. Every quarter of delay accumulates approximately $1,460,000 in avoidable disposal costs at Phase Initial scale and shifts the royalty start date by one quarter — permanently forfeiting that royalty income.
