Three documents examining Oʻahu's approaching waste infrastructure crisis — the mandatory 2028 WGSL closure, H-POWER technology concerns, and Carbotura's Advanced Circular Manufacturing partnership opportunity.
A short introduction to Carbotura's ACM technology and the partnership model described in the documents below.
⚠ Disposal cost estimate is analyst estimate — H-POWER and WGSL contract rates commercially confidential. All financial projections are Carbotura estimates carrying low confidence. Independent verification required.
Three documents comprise the Oʻahu, Hawaii Stage 1 suite. Start with the Executive Briefing, then explore the full intelligence and proposal documents below.
A decision-maker summary of Oʻahu's 2028 waste infrastructure crisis and Carbotura's Advanced Circular Manufacturing partnership opportunity. Written for elected officials, senior officers, and engaged residents. Five key findings, accountability pathways, and named contacts.
Full 13-section analysis of Oʻahu's solid waste sector — market structure, operator landscape, regulatory record, cost analysis, and financial liabilities. Primary data source for the EIR & Proposal. WGSL closure timeline, H-POWER dependency, and liability quantification.
Complete three-tier proposal with Status Quo analysis (SQ1–SQ5), Economic Impact Report (EIR1–EIR7), Proposal sections (P0–P5), and full appendices including P&L, balance sheet, cash flow, and 24-source bibliography.
Waimanalo Gulch Sanitary Landfill must cease operations by March 2, 2028, under a binding State Land Use Commission order. No replacement landfill has been permitted. H-POWER's combustion ash — approximately 150,000 tons per year — will have no legal disposal route on Oʻahu from that date.
Carbotura proposes an Advanced Circular Manufacturing facility that accepts Oʻahu's community-sourced feedstock as manufacturing input — with near-zero residuals to landfill by design — while delivering a Circular Royalty™ back to the community beginning 13 months after first feedstock delivery.
This is a Stage 1 document suite. All financial projections are illustrative estimates produced by Carbotura Inc. as an interested commercial party. Independent financial, legal, technical, and procurement advice is required before any decision.
