Rhode Island generates an estimated 895,000 TPY of manufacturing feedstock — municipal solid waste, wastewater biosolids, incinerator ash, and legacy coal ash — with a single disposal point, a hard 2027 sludge infrastructure deadline, and no in-state industrial alternative. Carbotura proposes a 30-year Build-Own-Operate Circular Operating Agreement to convert this feedstock into domestic industrial materials at zero state capital obligation, generating a Circular Royalty that exceeds the TMC Fee from Year 2. The six documents below constitute the complete engagement package.

Planning basis: All financial projections use Carbotura standard contractual parameters and estimated disposal cost data. FWDC ($101.67/ton) is a modeled blended calculation subject to verification in the Community Feasibility Study. Employment and impact figures use Carbotura standard parameters scaled to deployment configuration. Hard deadline (2027 Synagro contract expiry) is verified per public reporting. All figures marked ESTIMATED carry data confidence limitations described in the Waste Study and EIR. This package does not constitute financial advice or a binding commitment.
