A manufacturing company.
Not a waste company.
Carbotura builds and operates ACM facilities — industrial plants that receive municipal and industrial materials as a manufacturing feedstock and convert them into synthetic graphite, recovered metals, and clean water. These are manufactured goods sold in global markets.
ACM is not incineration. It is not recycling. It is not waste treatment. The process runs in an oxygen-free, sub-atmospheric chamber using microwave catalytic energy. There is no combustion, no flame, and no stack emissions. Materials are not destroyed — they are reformed into products.
This classification matters: Carbotura operates under manufacturing North American Industry Classification System (NAICS) codes (Sector 31–33), not solid waste codes. The facility is a factory. The materials Miami-Dade delivers are its manufacturing inputs.
What Carbotura is offering Miami-Dade County
Carbotura designs, finances, builds, owns, and operates the facility entirely at its own cost. The county's only obligation is delivering waste. No bonds. No budget line. No balance sheet exposure at any phase from $305M through $3.47B full deployment.
Carbotura converts waste materials into synthetic graphite, recovered metals, and clean water — manufactured products sold in global markets. Under both options, Miami-Dade begins receiving Circular Royalty™ payments starting Month 14. Cash the county earns back from materials it was previously paying to dispose of. What was an escalating cost becomes a source of income — the same waste the county was paying to get rid of now pays the county back.
South Dade Landfill reaches capacity around 2029. Phase Initial goes online by mid-2028 — ahead of the capacity crunch. That arrives before any Waste-to-Energy (WTE) contract ties Miami-Dade to 40 years of escalating rates.
The proposed WTE contract prices at $105/ton rising indefinitely. Under the CSA, the Beneficiation Fee (TMC Fee) starts at $88/ton — $17 below WTE from Day 1. Both escalate at 2.5%/yr. The savings gap widens every year in Miami-Dade's favour for 30 years.
$28.5M gross cost avoidance plus ~$696M in Circular Royalty™ received over 30 years. This is the floor, not the ceiling. At full deployment (6,000 TPD), Carbotura projects ~$8.69B — 12× Phase Initial. None of this requires county capital.

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.
Beneficiation Fee (Total Material Conversion Fee): $88.00/ton Year 1 · +2.5%/yr escalator · Circular Royalty™: 120% of that year's Beneficiation Fee · +1 percentage point/yr · payments begin Month 14 (rolling lagged cash flow) · 30-yr totals: Carbotura planning-basis ESTIMATED · linear scaling from verified Phase Initial projection · Beneficiation Fee and Circular Royalty™ are independent transactions — gross figures shown separately per programme terms · Direct jobs (FTE) scaled linearly from Carbotura standard 400 TPD baseline (100 direct FTE per facility) · indirect/induced employment runs at ~3× direct (regional economic effect, distinct from facility headcount) · Miami-Dade County addressable volume: 7,225 TPD · Phase Initial addresses 7% of total
