Oʻahu, Hawaiʻi · City & County of Honolulu · Advanced Circular Manufacturing

We pay a royalty on the feedstock you supply.

What leaves your county as a disposal liability returns as a royalty — paid by Carbotura from the manufactured products your materials become. One CSA structure. Zero county capital.

What is Feedstock?
Manufacturing Feedstock
The materials Oʻahu generates — collected, delivered, and converted into manufactured products inside a Carbotura ACM facility. Not waste. Not garbage. A manufacturing input.
What is Beneficiation?
Beneficiation (ACM)
The industrial process of converting a raw secondary material into a valuable manufactured product — synthetic graphite, graphene compounds, recovered minerals. What Carbotura does.
✓ $0 Community Capital ✓ Royalty from Year 2 ✓ 30-Year CSA ✓ WGSL Closure Solution ✓ PFAS Destruction

What this document is

The entry point for Carbotura’s Circular Advantage engagement with the City and County of Honolulu — the documents covering the feedstock system, the commercial structure, the economics, the decision and what it means for residents.

Three things this document says
  1. The City and County of Honolulu is at a decision point: WGSL closes on 2 March 2028 under a binding Land Use Commission decision, so the Joint Working Group must be authorised by mid-2026.
  2. Advanced Circular Manufacturing converts the residual stream into products under one agreement, with no the City capital committed.
  3. The engagement decision has to be taken while the option is still open — authorising later forecloses the earlier phases.

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.
