Oʻahu, Hawaiʻi — Economic Impact Report

At the planning-basis FWDC, ACM deployment delivers a Circular Royalty™ of $120/ton from Year 2 — at zero City & County capital. The Exogenesis™ Royalty bonus, when available, adds an independent landfill remediation royalty stacking on the CSA.

Sections

§1 — Introduction and Decision Summary

§1.1 — What This Report Measures

This EIR models the delta between State A (current condition — feedstock to H-POWER and WGSL, with WGSL closing March 2, 2028) and State B (ACM deployment at 200 TPD Phase Initial, COD Q1 2028). Neither state is re-diagnosed in this report; data flows from the Waste Study and Proposal EIR Input Block respectively.

§1.2 — Decision Summary

Analysis Basis

Under the CSA the City & County pays the Beneficiation Fee and receives the Circular Royalty™. The Legacy Remediation Royalty ($50/ton from WGSL extraction, Exogenesis™ path) is a CSA add-on available where a qualifying legacy landfill is confirmed, described in Proposal §4.1. Both streams are reported as separate transactions per the Separate Transaction Principle (MR §4.8).

Year 1 / Year 2+ separation: Beneficiation Fee (TMC Fee) obligation and Circular Royalty™ receipt are independent transactions shown as separate rows in all tables. They are never netted, offset, or combined. ACM permitted only under manufacturing NAICS 325180, 325998, 327992, 331110, 331314, 331492. Solid waste codes (562212 / 562213 / 562219 / 562920) are expressly excluded. Both parties commit to the RPT pathway; the endpoint is categorical — manufacturing classification across all permitting, licensing, and regulatory contexts. Interim bridging authorities may apply during the transition.

§4 — Delta Analysis

Three delta components: (1) gross cost displacement; (2) Circular Royalty™ cash flow; (3) residual obligation. All shown as independent transactions per MR §4.8 — never netted.

30~$207$204.64$14,938,770$295.44$21,567,120$0

Royalty figures are amounts received. The royalty is paid 13 months in arrears, so the figure shown for a year is earned on the previous year’s delivered tonnage.

All figures MODELED at 200 TPD / 73,000 TPY Phase Initial. Beneficiation Fee and Circular Royalty™ are independent transactions — never netted.

§4.3 — Pre-Royalty Period Separation (Required)

Year 1 and post-Month 13 periods have materially different fiscal characteristics. They must not be combined. In Year 1: the City pays the Beneficiation Fee ($100/ton) and receives zero Circular Royalty™ — pre-royalty period. Post-Month 13: Circular Royalty™ payments begin at $120/ton. Both are independent transactions — the Circular Royalty™ exceeds the Beneficiation Fee by $17.50/ton in Year 2, with that spread compounding annually through Year 30.

§4.4 — 30-Year Gross Cost Displacement

PeriodAvoided Disposal Cost / TonAnnual Gross Cost Displacement (200 TPD)Cumulative (200 TPD)
Year 1~$103 EST~$7,519,000~$7,519,000

Year 30~$207~$15,227,000~$324,000,000

All ESTIMATED. Gross cost displacement = avoided WGSL disposal cost at FWDC ~$103/ton escalating 2.5%/yr. Shown independent of Beneficiation Fee — separate transaction per MR §4.8.

Regional economic effects are not county fiscal receipts. Environmental figures use “designed for” qualifying language per MR §1.3.

§5.4 — No-Fallback Analysis: State A has no contracted alternative to WGSL at the March 2, 2028 regulatory closure date. Off-island shipping ($99/ton, COVID-period verified) is the only backstop — volume-limited, not scalable to 880 TPD as a permanent solution. Makaiwa Hills (identified December 2024) requires Act 73 amendment, EIS, acquisition, and construction — minimum 4–6 years from authorization, not resolvable by 2028. State A does not have a self-resolving pathway to March 2028 compliance.

§7 — Decision Window Analysis

§7.3 — Irreversibility Mechanism

The specific instrument creating irreversibility is the LUC Decision & Order (D&O, November 1, 2019; SUP SP09-4031): WGSL “shall not accept any form of waste after March 2, 2028.” This is an enforceable court order. Authorization of the Joint Working Group phase by mid-2026 preserves the Phase Initial COD Q1 2028 pathway. Authorization delayed to Q4 2026 shifts COD to Q3–Q4 2028 — creating an uncovered gap of 3–6 months at the LUC-mandated closure date.

What this document is

What the City and County of Honolulu pays and receives under its current system compared with an Advanced Circular Manufacturing deployment — each flow quantified and reported separately across the 30-year term.

Three things this document says
  1. Continuing with the current system leaves the City and County of Honolulu exposed to a date it does not control: 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. Under the CSA the City and County of Honolulu pays a Beneficiation Fee and receives a Circular Royalty™; both are gross figures and are shown independently throughout.
  3. The direction of the conclusion holds across the sensitivity range, including where the unconfirmed disposal cost is verified lower than the planning estimate.
Looking for something else?
Canonical Principles
  1. Carbotura is a manufacturer, not a waste manager. Advanced Circular Manufacturing converts delivered feedstock into products; it does not manage or dispose of waste.
  2. The Beneficiation Fee and the Circular Royalty™ are independent transactions. They are reported separately and in full, and are never netted against each other.
  3. Hydrogen powers the facility internally — it is generated and consumed on site to run the process, and is not sold as offtake.
