What this document is
A single-page action instrument: what the County commits, what it receives, and the one action to authorise before landfill expansion engineering is contracted.
- 1The Immokalee landfill’s post-closure obligation runs through ~2033 and cannot be transferred retroactively; the expansion engineering vote is the decision point.
- 2One CSA: a $100/ton Beneficiation Fee, and a Circular Royalty™ of $7.92M in Year 2 growing to ~$395M gross over 30 years at Phase Initial.
- 3One action: execute an LOI/MOU before the Board’s expansion engineering vote.
Why this matters — what Carbotura is offering Collier County
Collier County disposes its residual at a published blended rate of $88.50/ton (Resolution No. 2025-184, Schedule C, effective 1 October 2025) and carries the closed Immokalee landfill’s FDEP post-closure obligation through ~2033. That liability cannot be transferred to Carbotura retroactively — the Exogenesis™ add-on must be incorporated at CSA signing. Once landfill expansion engineering is contracted, that capital is locked in; executing an LOI/MOU before the vote keeps the CSA alternative open for that capacity.
Carbotura converts the residual Collier County currently buries into manufactured Circular Materials — synthetic graphite, graphene compounds, recovered minerals, plus net-positive ultrapure water — by primary elemental dissociation in an oxygen-free process. Not landfill, not incineration, not waste-to-energy: manufacturing.
The County’s blended disposal rate is $88.50/ton, modeled from its own FY26 fee schedule. The Beneficiation Fee is set at $100/ton, escalating 2.5%/yr — at Phase Initial (200 TPD, 66,000 TPY) that is $6.60M in Year 1. Carbotura funds 100% of the facility; the County commits feedstock, not capital.
Beginning 13 months after the first Beneficiation Fee payment, the County receives a rolling monthly Circular Royalty™ — $7.92M in Year 2 at Phase Initial, 120% of that year’s fee, adding a percentage point every year. Over the 30-year term that is approximately $395M gross at Phase Initial and $1.58B at 800 TPD. Fee and royalty are two transactions and are shown separately throughout.
Why this fits Collier County
The Immokalee landfill (closed 2003) carries an FDEP post-closure obligation through ~2033. The Exogenesis™ add-on that addresses it must be incorporated at CSA signing — it cannot be added retroactively.
Resolution No. 2025-184, Schedule C (effective 1 October 2025) sets residential MSW at $88.20, commercial at $90.35 and biosolids at $79.25 — a blended $88.50/ton against which the $100/ton Beneficiation Fee is set.
Collier’s in-county disposal structure presents no feedstock competition; the facility can plan to full Phase Expanded capacity — 800 TPD, ~79% of the 1,015 TPD IMMEDIATE stream — without supply uncertainty.
ACM Modular Production Units are manufactured and replicated under a Design for Manufacturability (DFM) model in 100 TPD increments — 200 TPD at Phase Initial (T0+24 months), 400 at Phase Medium, 800 at Phase Expanded.
Build-Own-Operate: Carbotura funds 100% at every phase. The Board’s landfill expansion engineering vote is the point at which County capital would otherwise be committed to the current route.
The structure, stated once
The Beneficiation Fee and the Circular Royalty™ are independent gross transactions with different payers. They are reported separately and never netted against one another.
The same physical mass is counted once in each of three dimensions — asset, revenue, attributes — and never summed as three independent masses.
Build-Own-Operate. Carbotura funds 100% of capital at every phase. The counterparty commits feedstock, not money.
One Circular Supply Agreement
+ Circular Royalty™
- Beneficiation Fee: $100–150/tonne · set at Term Sheet against the verified FWDC · 2.5%/yr escalator
- Circular Royalty™: 120% of the current-year Beneficiation Fee in Year 1 ($120–180/tonne), +1pp/yr, uncapped
- Royalty commencement: 13 months after the first Beneficiation Fee payment, rolling monthly on delivered tonnage
- Perpetual CSA, 30-year minimum term · Build-Own-Operate · zero counterparty capital
- Feedstock transfers under the CSA — ownership and liability pass at collection or delivery
- Accounting basis: US GAAP / GASB
The closed Immokalee landfill is carried as an Exogenesis™ candidate — converting accumulated legacy material into a Legacy Remediation Royalty alongside the primary CSA, with the FDEP post-closure obligation addressed at signing. Subject to feedstock characterisation; not part of the base case.

FWDC $88.50/ton MODELED. Beneficiation Fee $100/ton. Circular Royalty™ (Year n) = (120% + (n−1)pp) × that year’s Beneficiation Fee; payments commence 13 months after the first fee payment and roll monthly. 30-Year Gross Royalty is gross royalty over 30 payments, ESTIMATED. Fee and royalty are independent gross transactions and are not netted anywhere in this document.
