Community Intelligence Briefing — Oʻahu, Hawaii

Key Terms & Acronyms

Status Quo Analysis

A1. Current Waste Management Structure

Oʻahu's solid waste system is built around a single combustion facility (H-POWER, operated by Reworld Honolulu LLC) and a single landfill (WGSL, operated by WM of Hawai'i Inc.). Both facilities are city-owned; both operators are private contractors. Mandatory flow control legislation (ROH §42-4.2) requires all private haulers of combustible waste to use H-POWER — eliminating competition at the gate. City ENV · Business Rules 2024

A2. Key Financial Data

A3. Regulatory Framework — Key Items

The binding LUC Order (Docket SP09-403, November 2019) closes WGSL by March 2, 2028. LUC 2019 Act 73 (2020) restricts new landfill siting to ½ mile from residences and prohibits conservation district sites. Hawaii Act 73 · 2020 Hawaii's Aloha+ Challenge targets 70% waste diversion by 2030; under the statutory definition (HRS §342G-01), Oʻahu's genuine diversion rate is approximately 34–38%, not the 77% the city claims by including H-POWER incineration throughput. MED

A4. Identified Liabilities

A5. Community Impact — Status Quo

Under the status quo, Oʻahu residents receive no direct financial return from their waste stream — all revenue from electricity generation and disposal fees accrues to contracted private operators under commercially confidential terms. The combination of a hard 2028 landfill closure deadline and ageing primary processing infrastructure creates a structural risk to service continuity from March 2028. West Oʻahu communities have borne disproportionate waste infrastructure burden through WGSL's operation since 1987.

Intelligence Analysis

B1. Market Structure & Operator Mapping

The Oʻahu disposal market is a statutory duopoly at the processing and landfilling level — Reworld (H-POWER) and WM of Hawai'i (WGSL) control all terminal disposal capacity. Both are subsidiaries of large national corporations. Mandatory flow control ensures guaranteed throughput for H-POWER regardless of market conditions — effectively insulating the operator from competitive pressure on pricing or technology improvement.

B2. Contract Architecture

The H-POWER operating agreement and WGSL management contract are commercially confidential. Contract term, renewal provisions, break clauses, and fee escalation mechanisms are not publicly disclosed. The Hawaii UIPA (HRS Chapter 92F) provides a formal mechanism for requesting these documents. Without access to contract terms, public officials and residents cannot independently assess whether the city receives market-competitive pricing for its primary waste services.

B3. Financial Flows — Key Gaps

Whether H-POWER electricity revenue (from 46–73 MW sold to Hawaiian Electric) accrues primarily to the city or to Reworld under the operating contract is not publicly disclosed. This is a material financial gap: annual electricity revenue could represent $30–65M at prevailing Hawaiian rates. LOW

B4. Risk & Liability Exposure

Five converging risks arrive between 2026 and 2030: (1) WGSL closure — March 2028; (2) PVT Landfill approaching capacity — ~2028–2030; (3) H-POWER technology investment needs; (4) ash recycling project not yet operational; (5) Hawaii 70% diversion target — 2030. Under the statutory definition, all five risks remain substantially unaddressed under the status quo trajectory.

ACM Partnership Proposal

C1. What Changes — Status Quo vs. ACM

C2. Financial Model — Three Tiers

All figures LOW confidence — Carbotura standard deployment model. Per-resident/yr = 30-yr benefit ÷ 1,000,000 residents ÷ 29 (Years 2–30). Circular Royalty™ begins 13 months after first feedstock delivery.

C3. Three Facility Scale Tiers

400 TPD is a proof-of-partnership deployment. 1,000 TPD materially reduces the WGSL intake and delivers the strongest balance of community benefit and manageable scale. 2,000 TPD processes approximately 60% of Oʻahu's MSW stream, substantially eliminating the need for a full-scale replacement landfill and delivering ~$1.195B over 30 years.

C4. The Manufacturing Process

Carbotura's system integrates proven component technologies — including microwave energy, catalytic reforming, and advanced separation — each with decades of industrial use. The Recyclotron™ reactor uses electromagnetic energy in an anoxic (no-oxygen) environment. No combustion occurs. This is categorically distinct from H-POWER, which combusts feedstock. ACM produces RevCon™ manufactured outputs — Liquifact™, manufactured mineral aggregate, Renewable Graphite, and Renewable Refined Water — along with Recovered Thermal Energy and Recovered Electrical Energy.

C5. Circular Royalty™ Structure

The Circular Royalty™ is calculated at the Business Baseline — 50% of current market pricing for RevCon™ outputs. It begins 13 months after first feedstock delivery (not simply "Year 2" — this precise language governs all timing statements). It grows at 4% per annum compound over the 30-year term as output prices and volumes increase. It is paid to the City & County of Honolulu through the Solid Waste Special Fund or as directed by the Circular Offtake Agreement. All projections LOW.

C6. 30-Year Engagement Timeline

Community & Resident Impact

D1. Household Cost Impact

Under ACM, the city's net disposal cost per ton is projected to fall by ~$15/ton ($165 FWDC → $150 TMC Fee) in Year 1, plus the Circular Royalty™ from Year 2. The Solid Waste Special Fund — the city's proprietary fund for waste operations — would receive growing Circular Royalty™ income that can offset future rate increases or fund other waste infrastructure. No direct household billing change is implied by Stage 1 commitments. LOW

D2. Service Changes

Feedstock collection routes and collection frequency are not changed at Stage 1. Feedstock Hauler contracts govern delivery to the ACM facility — existing collection vehicles can be transitioned. The ACM facility would accept the same mixed community feedstock stream currently going to H-POWER, requiring no material change in householder sorting behaviour.

D3. Environmental Outcomes

ACM is designed for near-zero residuals to landfill and near-zero greenhouse gas emissions from the reforming process. This is projected to substantially eliminate the ~150,000 t/yr combustion ash burden on WGSL, reducing the landfill's operational obligations and post-closure monitoring scope. Under process design specification. Independent verification at Oʻahu scale is ahead. LOW

D4. Jobs & Economic Development

A 1,000 TPD ACM facility is projected to support approximately 200–300 direct and indirect permanent jobs in Oʻahu's economy. These are manufacturing roles — providing economic diversification beyond tourism and government employment, which together represent the dominant employment sectors on Oʻahu. LOW

Accountability & Action Pathways

F1. Named Officials Responsible for Current Decisions

Decision-making on Oʻahu's waste strategy rests with: the Mayor, City & County of Honolulu (honolulu.gov/mayor); the Director, Dept. of Environmental Services (honolulu.gov/env); and the Honolulu City Council (honolulucitycouncil.org) — which controls the budget appropriation process and passed the landfill working group resolution in January 2026.

F2. Key Decision Dates

F3. Public Records Request Guidance

Under Hawaii's Uniform Information Practices Act (UIPA, HRS Chapter 92F), any person may request public records from the City & County of Honolulu. Key documents to request for independent analysis: (1) H-POWER operating contract with Reworld Honolulu LLC — financial terms; (2) WGSL management contract with WM of Hawai'i Inc. — financial terms; (3) City ENV internal assessments of post-2028 ash disposal options; (4) H-POWER air quality permit compliance reports since 2020.
