Miami-Dade’s Feedstock Management System — A Structural Crisis Report
- Miami-Dade generates manufacturing feedstock at 2× the US per-capita average. The county officially acknowledges it generates more than twice the national per-capita average of 4.9 lbs/person/day. At 2.72 million residents, this implies a total feedstock stream of approximately 5,300–5,500 TPD residential alone, with commercial streams adding substantially to the total. This is not an environmental failure — it is a raw material endowment of exceptional scale.
- The primary processing facility has been permanently closed. The Resources Recovery Facility (Covanta, Doral) processed up to 4,000 TPD and approximately 1 million tons per year. Destroyed by fire in February 2023 and permanently decommissioned by the Board of County Commissioners in September 2023, it has not been replaced. The county is managing approximately 1 million tons of annual overflow through emergency landfill capacity arrangements.
- North Dade Landfill is projected to reach capacity by approximately 2026. South Dade Landfill by approximately 2030. Combined initial closure costs estimated at $50M. Annual landfill revenue forfeited post-closure exceeds $50M/yr. Both landfills are adjacent to sensitive groundwater zones and represent PFAS leachate liability under the April 2024 CERCLA designation.
- The DSWM faces a $39M structural deficit in its Collections Fund. The FY 2024–25 shortfall is covered by an internal loan from the Disposal Fund — not a structural solution. Household fees stand at $547/year and face upward pressure. The county’s per-capita feedstock generation rate is twice the national average, yet its collection and disposal system generates a structural deficit.
- Florida’s recycling credit framework creates a perverse dependency on combustion. Florida Statute §403.706(4)(a) allows each MWh produced from a WTE facility to count as 1 ton toward recycling goals. Miami-Dade used this mechanism to meet its state recycling goals via the RRF. With the RRF permanently closed, Miami-Dade’s recycling rate has structurally declined — and any new combustion replacement is designed to restore those credits, not eliminate the dependency.
- Miami-Dade has a Zero Waste goal it cannot achieve under the current system. The 2021 Climate Action Strategy set a target of reducing per-capita landfill feedstock by 50% by 2030. The Zero Waste Master Plan is expected to be completed in 2026. At current per-capita generation (2× national average) and with no replacement processing capacity, the county is moving away from, not toward, its stated goals.
- The proposed replacement is another combustion facility under FDEP preliminary permit review. Three sites have been submitted: Opa-Locka West Airport (first choice), Medley (second choice), and the former Doral RRF site (third choice). No site has been confirmed. No construction contract has been executed. Documented community opposition exists at all three candidate sites. Capital commitment estimated at $800M–$1.5B+.
- Miami is ranked the 3rd most PFAS-contaminated groundwater city in the US. PFOS in Miami drinking water measured at 18.98 ppt — 4.7× the EPA limit of 4 ppt. PFOA at 7.2 ppt — 1.8× limit. Both landfills are adjacent to sensitive groundwater zones. PFAS leachate from landfill operations is an established contamination pathway. CERCLA hazardous substance designation (April 2024) activates retroactive operator liability.
HIGH Public record · MED Derived estimate · LOW Preliminary — requires site verification
Miami-Dade County’s manufacturing feedstock management system is in structural failure across four simultaneous dimensions: capacity, finance, environment, and regulatory compliance. A system designed around combustion, landfill disposal, and per-household fee extraction is structurally incapable of meeting the county’s own stated goals of zero waste, per-capita reduction, and environmental protection. This report documents that failure in detail — as the evidentiary basis for understanding why Advanced Circular Manufacturing is not an option for Miami-Dade. It is the only viable industrial architecture that addresses all four failure dimensions simultaneously.

01Foundational Definitions
Miami-Dade’s feedstock management regulatory framework operates across three layers: federal RCRA and EPA designation authority, Florida state statute and administrative code, and Miami-Dade County ordinance (Chapter 15). Understanding the definitional architecture at each layer is essential to interpreting market structure, liability exposure, and the ACM classification pathway.
Florida Statutory Framework
Defined as “sludge unregulated under the federal Clean Water Act or Clean Air Act, sludge from a waste treatment works, water supply treatment plant, or air pollution control facility, or garbage, rubbish, refuse, special waste, or other discarded material, including solid, liquid, semisolid, or contained gaseous material resulting from domestic, industrial, commercial, mining, agricultural, or governmental operations.” Key exemptions: hazardous waste (Chapter 5), radioactive materials (Chapter 7), regulated NPDES discharges, and — per 2020 additions — post-use polymers and recovered feedstocks processed through gasification or pyrolysis permitted as manufacturing operations.
“Any solid waste disposal area, volume reduction plant, transfer station, materials recovery facility, or other facility, the purpose of which is resource recovery or receiving, storing, altering, processing, or disposing of solid waste.” This definition is the basis for FDEP permitting jurisdiction. An ACM facility operating as a manufacturing facility — not a disposal facility, not a volume reduction plant, not a transfer station, not a materials recovery facility — falls outside this definition if all outputs are commercial manufactured products with commercial buyers.
“The governing body of a county has the responsibility and power to provide for the operation of solid waste disposal facilities to meet the needs of all incorporated and unincorporated areas of the county.” Miami-Dade’s BCC carries this statutory obligation. The RRF provided a significant portion of this capacity. Its permanent closure without replacement creates a statutory compliance risk: the county has an obligation it is currently meeting through temporary emergency agreements, not durable infrastructure.
Each MWh of electricity produced from a WTE facility counts as 1 ton of recycled material toward state recycling goals. If a county also recycles ≥50% by other means, the credit multiplies to 1.25 tons per MWh. Miami-Dade relied on this mechanism through the RRF to meet state recycling goals. With the RRF permanently closed, this credit stream has been entirely severed. Any WTE replacement would restore it. Any ACM deployment — which does not produce electricity by combustion — would require a separate regulatory determination to quantify equivalent credits for manufactured materials recovery.
Class I Landfill: Accepts Class I waste (non-hazardous solid waste). Must meet liner, leachate collection, groundwater monitoring, and final cover requirements. North Dade Landfill and South Dade Landfill are both Class I. Class III Landfill: Accepts yard trash, construction and demolition debris, cardboard, newspaper, and non-putrescible materials only. Transfer Station: Intermediate receiving facility — material does not remain more than 48 hours. Miami-Dade operates three Regional Transfer Stations under this classification.
Chapter 15 governs all private solid waste collection in Miami-Dade. Key provisions: (1) All commercial and private haulers operating within the county must hold a county-issued hauler permit. (2) The county holds flow control authority over residential feedstock generation within the DSWM service area. (3) Permitted private haulers are subject to annual renewal, insurance requirements, and DSWM inspection. (4) Chapter 15 defines the legal basis for the Feedstock Hauler transition pathway under the Circular Advantage program — existing permitted haulers transition by agreement, not by new permit category.
The Resource Conservation and Recovery Act (RCRA) Subtitle D governs non-hazardous solid waste through minimum national standards implemented by states. Florida’s FAC Rule 62-701 implements RCRA Subtitle D. Key implications: (1) Landfill closure and post-closure financial assurance requirements are RCRA-derived. (2) The 30-year post-closure monitoring obligation begins at landfill closure. (3) RCRA’s 40 CFR 261.2(e) provides the manufacturing exclusion from solid waste definition that forms part of the ACM classification defense — materials used as ingredients in a manufacturing process to make a product are excluded from the definition of solid waste.
The FWDC is the Carbotura benchmark against which the TMC Fee is calibrated. For Miami-Dade, the FWDC is derived from the October 2025 DSWM fee schedule weighted by material stream composition estimates. Full derivation is in Section 12. Summary: Contract landfill gate fee ($16.28/ton) + transfer station fee ($16.66/ton) = $32.94/ton minimum all-in for contracted parties. Non-contract rate: $33.82/ton. Including overhead allocation and transfer logistics, the FWDC weighted estimate is $35–$42/ton. MED — full derivation in s12
The single most consequential definitional question in Miami-Dade’s infrastructure transition is whether a new processing facility is classified as a “solid waste management facility” under §403.703(36) or as a manufacturing facility outside that definition. All permitting obligations, public input requirements, FDEP authority, and community opposition rights flow from that classification. Carbotura’s ACM facility is designed and operated as a manufacturing facility. This is not a regulatory gambit — it is the factual description of what the facility does. Establishing this classification proactively with FDEP and DERM is the single most important regulatory action Miami-Dade can take before any deployment decision.
02Industry Actors & Roles
Miami-Dade’s legacy feedstock management market is dominated by a single public operator (DSWM) for residential collection and two national private firms (Waste Management and Republic Services) for commercial hauling and overflow disposal. The permanent closure of Covanta’s RRF has removed the only large-scale non-landfill processing capacity and concentrated the feedstock stream onto two county landfills both projected to reach capacity within the current decade.
Miami-Dade DSWM
Role: Primary residential collection and disposal operator. Serves 340,000+ households across unincorporated Miami-Dade and 10 municipalities. Operates North Dade Landfill, South Dade Landfill, and 3 Regional Transfer Stations (NW, NE, South). Owns 13 Trash & Recycling Centers and 2 Home Chemical Collection Centers. Provides countywide mosquito control. FY 2024–25 budget: Collections Fund in $39M structural deficit. HIGH
County Operator — PrimaryCovanta Dade Renewable Energy (RRF)
Role: Operated the Resources Recovery Facility (Doral) from 1985 under county contract. Capacity: up to 4,000 TPD, ~1 million tons/yr, 77 MW electricity, ~22,000 tons ferrous metals/yr recovered. Destroyed by fire February 2023. Permanently decommissioned by BCC September 2023. Closure Plan filed with FDEP March 2024. Title V Air Permit withdrawn. Ongoing fire claims under negotiation with Sedgwick. All operations ceased. HIGH
Former Operator — Permanently ClosedWaste Management Inc. (WM)
Role: Largest national private hauler (~34% national market share by revenue). Active in Miami-Dade commercial and municipal hauling markets under Chapter 15 permit. Secured emergency capacity agreement post-RRF fire: up to 1 million tons additional disposal capacity at WM facilities, subject to contract renegotiation. Monarch Hill Landfill in Broward County (500-acre WM-owned site) provides South Florida regional overflow capacity. National landfill closure accrual: $3,057M. HIGH
Private Hauler / Overflow DisposalRepublic Services Inc.
Role: Second-largest national private hauler (~25% national market share by revenue). Active in South Florida commercial and municipal markets under Chapter 15 permit. No confirmed direct county disposal contract disclosed, but significant commercial market presence. National landfill closure accrual: $2,144M. Republic holds significant interest in potential post-RRF market restructuring as Miami-Dade’s disposal architecture evolves. MED
Private HaulerWaste Connections — JED Landfill
Role: Third-largest national private hauler. County negotiated additional 300,000 tons/yr disposal capacity at JED Landfill post-RRF fire, subject to contract renegotiation by March 2024. Provides northern county overflow buffer for material that cannot be accommodated at North Dade Landfill. HIGH
Overflow DisposalAtkinsRealis USA Inc.
Role: Design Criteria Professional and Owner’s Representative for the proposed WTE replacement facility. Contracted November 2023 (BCC Resolution R-1096-23). Design capacity: up to 4,000 TPD. Three candidate sites under FDEP preliminary permit review: Opa-Locka West Airport, Medley, former Doral RRF. No construction contract executed. No confirmed site. HIGH
WTE Replacement DesignMunicipal Inter-Local Partners
Role: 9 municipalities hold recycling inter-local agreements with DSWM: El Portal, Florida City, Medley, Miami Beach, Miami Springs, North Bay Village, South Miami, Virginia Gardens, West Miami. Plus 10 municipalities with full collection service agreements. These inter-local relationships define the feedstock supply network that would transition to the Circular Advantage program under any ACM deployment. HIGH
Feedstock Supply NetworkLicensed Private Haulers (Chapter 15)
Role: All commercial solid waste haulers operating in Miami-Dade must hold a county Chapter 15 hauler permit. This creates the existing licensed hauler network that would transition to Feedstock Hauler roles under the Circular Advantage program. Permitted haulers include national operators, regional firms, and local independents. The permit framework already establishes the regulatory basis for a structured Feedstock Hauler transition. HIGH
Licensed Hauler NetworkMiami-Dade’s current actor landscape is fragmented by crisis. The primary processing operator is permanently closed. Emergency capacity agreements with WM and Waste Connections are temporary bridges. The design contractor for the WTE replacement has no construction mandate. The two national private haulers (WM and Republic) hold combined emergency disposal commitments but no long-term processing infrastructure. This actor landscape is uniquely open to ACM deployment: no incumbent processor, no locked long-term contract, no vested interest in any specific replacement architecture — yet.
03Business Structure Models
Miami-Dade’s feedstock management system operates under three coexisting business structures: a public direct-service model (DSWM), a private permit-based model (Chapter 15 commercial haulers), and an inter-local agreement model (municipal partners). All three ultimately funnel feedstock to DSWM-owned infrastructure. The fourth model — BOO Advanced Circular Manufacturing — does not yet exist in Miami-Dade but is structurally compatible with all three existing frameworks.
| Model | Coverage | Capital Owner | Revenue Mechanism | ACM Compatibility |
|---|---|---|---|---|
| DSWM Direct Service | 340,000+ households in unincorporated MDC + 10 municipalities under full service ILAs | Miami-Dade County | Non-ad valorem assessment ($547/yr/HH). Landfill gate fees from contracted/non-contracted haulers. DSWM retains all gate revenue until landfill closure. | High — DSWM becomes feedstock supplier under COA. Non-ad valorem fee stream preserved (potentially reduced over time via Circular Royalty™). |
| Private Permit (Chapter 15) | All commercial, industrial, and C&D feedstock generation in Miami-Dade. Private residential in non-DSWM municipalities. | Private operators (WM, Republic, independents) | Commercial hauling contracts with generators. Gate fees to DSWM landfills or permitted private disposal sites. Recycling commodity revenue (volatile). | High — Chapter 15 permitted haulers transition to Feedstock Hauler roles. Same permit framework. New destination (ACM facility). No structural change to hauler business model. |
| Inter-Local Agreement | 9 municipalities (recycling ILAs): El Portal, FL City, Medley, Miami Beach, Miami Springs, N. Bay Village, S. Miami, Virginia Gardens, West Miami | County infrastructure / municipal collection | Service fees from municipalities to DSWM for disposal access. Municipalities retain collection operations. | High — ILAs become feedstock supply agreements under COA. Municipalities transition from disposal fee payers to feedstock suppliers receiving Circular Royalty™ allocation. |
| BOO — ACM Manufacturing | Not yet deployed in Miami-Dade. Option A (in-county full-stack) or Option B (rail-delivered feedstock from Miami-Dade Transfer Stations to Central Florida ACM Facility via FEC/CSX). | Carbotura Inc. — 100% capital risk | TMC Fee from Miami-Dade (in). Revenue Stack from manufactured materials sales (out). Circular Royalty™ to Miami-Dade (month 13+). | This is the proposed model. Replaces the WTE replacement capital commitment. Converts a cost system to a revenue system. |
DSWM Enterprise Fund Structure
DSWM operates as a county enterprise fund, structured into two sub-funds:
| Fund | Revenue Sources | Expenditures | Status FY25 |
|---|---|---|---|
| Collections Fund | Non-ad valorem assessment ($547/yr/HH). Service fees from municipalities. | Fleet operations, labor, equipment, fuel, collection infrastructure. | $39M structural deficit. Covered by internal loan from Disposal Fund. Future rate increases required. |
| Disposal Fund | Landfill gate fees ($16.28–$16.91/ton). Transfer station fees ($16.66–$16.91/ton). Special handling fees. | Landfill operations, transfer stations, TRC operations, regulatory compliance, closure reserves. | Currently solvent but providing internal loan to Collections Fund. Revenue at risk as landfills approach capacity. |
Miami-Dade’s three existing business structure models are all structurally compatible with ACM deployment. No model requires structural redesign — each transitions its role within the Circular Advantage program. Haulers become Feedstock Haulers. The county becomes a feedstock supplier. Municipalities become Circular Royalty™ recipients. The only structural change is destination: from landfill to ACM factory. The enterprise fund structure is preserved and improved — the structural deficit is resolved, not deferred.
04Waste Flow Control
Feedstock flow in Miami-Dade is governed by a combination of statutory authority (Florida §403.706), county ordinance (Chapter 15), and contractual inter-local agreements. The county holds flow control authority over residential feedstock within the DSWM service area. Commercial feedstock flow is regulated by the Chapter 15 permit framework but not subject to the same direct county flow control.
Material Stream Routing
| Stream | Volume Estimate | Current Routing | Conf. |
|---|---|---|---|
| MSW — Residential | ~1,800–2,200 TPD | DSWM collection (2×/week) → 3 Regional Transfer Stations → North Dade or South Dade Landfill. Pre-2023: significant volume routed to RRF (Doral). Post-RRF: entire stream to landfill. | MED |
| MSW — Commercial | ~1,500–2,000 TPD | Chapter 15 permitted haulers → DSWM landfills (contracted) or WM/Waste Connections facilities (for overflow). Miami-Dade’s commercial sector is dense and high-volume: hospitality, food service, retail, healthcare. | MED |
| Construction & Demolition (C&D) | ~400–600 TPD | Permitted C&D haulers → DSWM Class I landfills or private Class III facilities. Miami-Dade’s construction activity (highest in Florida by permit value) generates substantial C&D volumes. This stream is a significant ACM feedstock candidate for Exogenesis. | LOW |
| Organics / Food Waste | ~150–300 TPD | Primarily landfill-disposed. DSWM operates limited composting programs (yard trash mulching). No large-scale organics diversion infrastructure in place. Food waste from commercial generators largely goes to MSW stream. | LOW |
| Biosolids | ~50–100 TPD dry equiv. | Miami-Dade Water & Sewer Dept. (WASD) manages biosolids from Central and South District WWTPs. Primarily land-applied or sent to composting. PFAS contamination of biosolids from WWTPs is an active liability given landfill application sites and drinking water proximity. | LOW |
| Waste Tires | ~17,000 tons/yr | RRF handled ~1.7 million passenger tires/yr through tire shredding operation (separate from combustion, unaffected by fire). Post-RRF: tire shredding operation continued temporarily on-site. Tires now being shredded and trucked to landfill. This is a direct ACM feedstock opportunity. | HIGH |
| Special / Bulky Waste | Included in MSW estimate | DSWM offers 2 bulky waste pickups/year per household (up to 25 cu yd each). 13 TRCs accept oversized household items. Electronics and home chemicals: separate HazMat collection at 2 locations. Special handling fee: $87.85/load. | HIGH |
Transfer Station Network
| Facility | Location | Function |
|---|---|---|
| NW Regional Transfer Station | Northwest Miami-Dade | Receives residential and commercial MSW from northern collection routes. Compacts and loads for landfill transport. Primary relief point for North Dade Landfill catchment area. |
| NE Regional Transfer Station | Northeast Miami-Dade | Receives MSW from northeastern service area. Routes to North Dade or South Dade depending on capacity availability. |
| South Transfer Station | South Miami-Dade | Primary routing point for South Dade collections. Located proximate to South Dade Landfill. Critical node for feedstock routing under Option A or Option B ACM deployment in the southern county corridor. |
Miami-Dade’s post-RRF feedstock flow is entirely landfill-directed. 100% of the county’s ~4,800+ TPD feedstock stream now terminates in two landfills projected to reach capacity within 4 years. The transfer station network is in place, permitted, and operational — it is the exact logistics infrastructure that would deliver feedstock to an ACM facility. No new collection infrastructure is required for ACM deployment. The ACM facility is a destination swap: same haulers, same transfer stations, new terminus.
05Cashflow Architecture
DSWM’s financial architecture is an enterprise fund model split between a Collections Fund (fee-funded, in structural deficit) and a Disposal Fund (gate-fee-funded, currently solvent but providing internal support). Both funds face structural deterioration over the next 4–6 years as landfill revenues decline and operational costs compound.
Collections Fund — Revenue & Expenditure Architecture
| Item | Value | Conf. | Notes |
|---|---|---|---|
| Primary revenue — non-ad valorem assessment | $547/HH/yr | HIGH | FY 2025–26. Billed via property tax bill. 340,000+ households in direct DSWM service area. |
| Estimated total assessment revenue | ~$186M/yr | MED | $547 × ~340,000 households = ~$186M. Does not include municipal ILA service fees. |
| FY 2024–25 structural deficit | $39M | HIGH | Collections operations shortfall. Covered by internal loan from Disposal Fund. Driven by: recycling processing fees on 60,000 tons, COVID-era commercial-to-residential tonnage shift, 8.6% inflation (2022), 6.9% (projected 2023). |
| Prior fee level | $509/HH/yr | HIGH | FY 2022–23 rate. Fee has increased from $509 to $547 over two years — still insufficient to cover structural cost growth. |
| Fleet electrification program | In progress | HIGH | DSWM is deploying electric collection vehicles to reduce fuel costs and carbon footprint. Financed through equipment financing rather than direct capital expenditure. |
Disposal Fund — Revenue & Risk Architecture
| Revenue / Cost Item | Value | Conf. | Notes |
|---|---|---|---|
| Landfill gate fee — contract rate | $16.28/ton | HIGH | Oct 2025 schedule. For permitted haulers with long-term county contracts. |
| Landfill gate fee — non-contract rate | $16.91/ton | HIGH | For non-contracted parties. Oct 2025 schedule. |
| Transfer station fee (added to gate) | $16.66–$16.91/ton | HIGH | For material routing through Regional Transfer Stations. Effectively doubles all-in cost for material requiring transfer. |
| Annual landfill revenue (North Dade) | $17M+/yr | HIGH | County-disclosed figure. Revenue forfeited at landfill closure. |
| Total landfill revenue at risk (both facilities) | >$50M/yr | HIGH | Both landfills closing within 4 years of each other. This revenue disappears at closure with no identified replacement source under current architecture. |
| Landfill closure cost (both facilities) | ~$50M initial | HIGH | $25M per landfill for initial closure. Does not include 30-year post-closure monitoring, leachate management, or PFAS remediation. |
| Internal loan to Collections Fund | $39M | HIGH | Disposal Fund providing bridge loan to Collections Fund FY 2024–25. This reduces Disposal Fund reserves available for closure cost provisioning. |
Private Operator Cashflow Positions
| Operator | Miami-Dade Revenue Position | Notes |
|---|---|---|
| Waste Management Inc. | Commercial hauling fees + emergency disposal agreement income. National annual revenue: ~$21B+ (2024). | Emergency capacity agreement provides WM with incremental disposal revenue from Miami-Dade overflow — estimated 300K–1M tons/yr at market gate rates. No disclosed county rate for this arrangement. |
| Republic Services Inc. | Commercial hauling fees in South Florida market. National annual revenue: ~$16B+ (2024). | No confirmed direct disposal contract with Miami-Dade DSWM. Market presence in commercial stream provides ongoing collection revenue regardless of disposal infrastructure. |
| Waste Connections | JED Landfill disposal income from Miami-Dade overflow agreement (up to 300,000 TPY). | Subject to renegotiation. Provides national operator with strategic position in Miami-Dade’s disposal market during the capacity transition window. |
Miami-Dade’s current cashflow architecture is a two-fund system in simultaneous deterioration. The Collections Fund runs a $39M structural deficit supported by the Disposal Fund. The Disposal Fund’s primary revenue disappears as both landfills close within four years. The ACM deployment changes this architecture permanently: TMC Fees replace disposal gate fees (competitive cost parity), Circular Royalty™ creates a new revenue stream from month 13, and the $50M landfill closure capital obligation is deferred through feedstock diversion. The cashflow benefit of ACM compounds annually for 30 years.
06Full Value Chain
A value chain analysis of Miami-Dade’s feedstock management system reveals a structural destruction of value at every stage. Material that contains carbon, hydrogen, metals, rare earth elements, and mineral compounds is collected, transferred, compressed, and buried — permanently removing all commercial value. The ACM value chain inverts this destruction into a production system.
Current System — Value Destruction Chain
| Stage | Activity | Value Created | Value Destroyed | Cost to County |
|---|---|---|---|---|
| Generation | Miami-Dade households and businesses generate ~4,800+ TPD of manufacturing feedstock | Raw material endowment | None at this stage | $0 (collection fee comes next) |
| Collection | DSWM and Chapter 15 haulers collect 2×/week | Logistics service | Material contamination in mixed streams | ~$186M/yr in non-ad valorem fees |
| Transfer | 3 Regional Transfer Stations compact and consolidate loads | None | Additional commingling | $16.66–$16.91/ton additional fee |
| Disposal | Material buried in Class I landfill cells | None — permanent loss | 100% of material value destroyed permanently. Carbon, hydrogen, metals, rare earths — all entombed. | $16.28–$16.91/ton gate fee |
| Net Value to Miami-Dade | Per ton delivered: net cost of $33–$34+ (gate + transfer). No material value recovered. | All commercial value permanently destroyed. Landfill capacity depleted. PFAS accumulates. | ||
ACM System — Value Creation Chain
| Stage | Activity | Value Created | Output | County Cashflow |
|---|---|---|---|---|
| Generation | Same ~4,800+ TPD feedstock stream | Raw material endowment | Manufacturing feedstock | $0 change |
| Collection | Same DSWM / Chapter 15 Feedstock Haulers | Same logistics value | Feedstock at enclosed receiving bay | Same fee structure — no increase |
| Pregenesis | Shredding, metals separation, Liquifact extraction | Metals separated, Liquifact extracted | Prepared feedstock stream + early-stage metals + Liquifact | TMC Fee ≤ current disposal cost |
| Regenesis | Recyclotron™ — anoxic Microwave Catalytic Reforming at 650°C+ | OmniCrude™ — molecularly disintegrated intermediate | OmniCrude™ — elementally rich, commercially valuable | Manufacturing in progress |
| Regenesis MAX | Selective refining: carbon activation, graphitization, hydrogen separation, metals purification, water purification | Full RevCon product portfolio | Graphite, graphene, hydrogen, metals, rare earths, ultrapure water — RC3–RC5 value range | Revenue Stack begins |
| Net Value to Miami-Dade | TMC Fee ≤ current cost. Circular Royalty™ from month 13. Revenue Stack at RC3 baseline: $185–$300M/yr per 400 TPD. | Zero landfill capacity consumed. PFAS destroyed at molecular level. 30-year Circular Royalty™ stream generated. | ||
Miami-Dade’s current value chain takes the most carbon-dense feedstock stream in the United States (2× national per-capita average) and systematically destroys 100% of its commercial value. The ACM value chain takes the same stream and converts it into a Revenue Stack of manufactured materials worth $185–$300M per 400 TPD annually. The difference between these two chains is not technology. It is industrial categorization and commercial intent. Miami-Dade’s feedstock is not a disposal problem. It is the raw material for one of the most valuable manufacturing businesses in South Florida history.
07Market Concentration
Miami-Dade’s feedstock management market is concentrated across three structural categories: public residential (DSWM dominates), private commercial (WM and Republic hold significant share), and disposal infrastructure (DSWM holds near-monopoly on county disposal capacity, with emergency overflow at WM and Waste Connections). The RRF closure has temporarily weakened DSWM’s disposal market position while creating a strategic window for non-combustion alternatives.
Market Share by Segment
| Segment | DSWM Share | WM Share | Republic Share | Other Private | Conf. |

Concentration Risk Analysis
Single-Point Disposal Failure
Pre-RRF fire, Miami-Dade had RRF + 2 landfills + 3 transfer stations. The RRF provided ~40–50% of disposal capacity as a non-landfill alternative. Its permanent closure created a single-point-of-failure architecture: all feedstock now goes to two landfills. This concentration risk materialised catastrophically in February 2023 and has not been structurally resolved.
National Operator Dependency
Miami-Dade’s emergency overflow capacity is entirely dependent on two national operators (WM and Waste Connections) under temporary agreements. If either operator re-prices or declines renewal, the county has no backstop. This dependency is the direct result of losing the RRF without a structural replacement in place.
WTE Replacement Incumbent Advantage
The proposed WTE replacement process is a design-and-build procurement that structurally favours national operators with WTE construction experience (Covanta/Reworld, WM, Republic subsidiaries). This procurement architecture risks recreating the single-operator dependency that was exposed by the RRF fire — with a new 30-year combustion lock-in at ~$1B+ capital cost.
ACM Breaks the Concentration Cycle
The Carbotura BOO model introduces a new disposal category (ACM manufacturing) that is not dependent on landfill capacity, not subject to combustion permitting battles, and not controlled by any existing market incumbent. It diversifies the county’s infrastructure architecture for the first time since the RRF was built in 1982.
Miami-Dade’s feedstock management market is dangerously concentrated in two aging landfills both approaching capacity and one emergency overflow arrangement that has not been formalised into a long-term contract. The proposed WTE replacement would trade one concentration risk (Covanta) for another (new WTE incumbent) at approximately 10× the capital cost. ACM deployment under BOO is the only architecture that structurally diversifies Miami-Dade’s disposal infrastructure while reducing concentration risk rather than re-creating it.
08Regional Analysis
Miami-Dade sits at the southern anchor of the South Florida regional feedstock management corridor. Its neighbours — Broward, Palm Beach, and Monroe counties — each have materially different infrastructure architectures, capacity positions, and regulatory relationships that directly affect Miami-Dade’s strategic options and the potential for a regional ACM deployment via the Option B rail corridor to a Central Florida ACM Facility.
| County | Population | Primary Disposal | WTE? | Landfill Status | ACM Opportunity |
|---|---|---|---|---|---|
| Miami-Dade | ~2.72M | DSWM direct — North & South Dade Landfills. Emergency overflow WM/Waste Connections. | No — RRF permanently closed 2023 | NDL ~2026 · SDL ~2030 | Primary ACM target. Largest feedstock volume. Capacity crisis most acute. |
| Broward County | ~1.95M | Broward County SWA. Primary facility: South Broward Landfill (500+ acres, WM-owned Monarch Hill). WIN Waste South Broward WTE facility (~824,000 tons/yr, combustion-based). | Yes — WIN Waste South Broward WTE. Still operational. | Monarch Hill Landfill has liner system; capacity timeline not publicly stated. | Secondary ACM target. WTE contract renewal window is ACM entry point. Proximity to Miami-Dade supports Option B rail-corridor feedstock aggregation at the Central Florida ACM Facility. |
| Palm Beach County | ~1.50M | Palm Beach County Solid Waste Authority (SWA). Most recent WTE greenfield in the US (2015). SWA operates comprehensive WTE + landfill + recycling system. | Yes — PBC SWA WTE, 2015 greenfield. Operational. | Landfill capacity extended by WTE diversion. Relatively stable near-term. | Future ACM partner via Option B rail corridor — WTE contract renewal is 20+ years out but Exogenesis for legacy deposits available sooner. |
| Monroe County | ~82,000 | Cudjoe Key disposal system. Limited population and feedstock volume. Primarily relies on exports to mainland. High environmental sensitivity — Florida Keys ecosystem. | No | Export-dependent | Rail-delivery feedstock partner for Option B — road transport to FEC hub (Miami), then rail north to Central Florida ACM Facility. Environmental premium for near-zero-emission processing in Keys context. |
Option B Regional Economics — Central Florida ACM Facility
The Central Florida ACM Facility model aggregates manufacturing feedstock delivered by rail from multiple Florida Transfer Station networks. At scale, Miami-Dade, Broward, and Monroe County supply could feed a Central Florida ACM Facility processing 2,000–3,000+ TPD of combined Florida feedstock, generating a Revenue Stack that benefits all contributing counties simultaneously:
| Node County | Est. Available TPD | Feedstock via Rail | Circular Royalty™ Recipient |
|---|---|---|---|
| Miami-Dade | 500–2,000+ | FEC / CSX Miami–Central FL corridor (Transfer Station rail loading) | Miami-Dade County (primary) |
| Broward | 300–600 | FEC / Tri-Rail connections northbound (Transfer Station rail loading) | Broward County SWA (future) |
| Monroe | 50–100 | Road transport to Miami FEC hub (Transfer Station rail loading) | Monroe County (future) |
| Central Florida ACM Facility Input (FL South) | 850–2,700 TPD | Aggregated at Central Florida ACM Facility | Multi-county Circular Royalty™ distribution |
Miami-Dade is not just a county with a feedstock management crisis. It is the southern anchor of a regional feedstock corridor encompassing Broward, Monroe, and potentially Palm Beach counties — a combined feedstock stream of 3,000–5,000+ TPD. The Option B architecture positions Miami-Dade to capture regional ACM economics through the Central Florida ACM Facility that no single-county full-stack deployment can approach alone. The rail corridor (FEC / CSX) is in place. The land is optioned. The only missing element is the first county to execute a Circular Offtake Agreement. Miami-Dade has every structural reason to be that county.
09Pain Points
Miami-Dade’s feedstock management system presents seven distinct and compounding pain points, each independently severe and collectively representing a structural failure across capacity, finance, environmental compliance, and governance. The accountability target in each case is the policy, infrastructure, or regulatory framework failure — not the community or its residents.
Pain 1 — Permanent Capacity Collapse (1 Million TPY Gap)
The RRF’s permanent destruction created a 1-million-ton-per-year processing gap that has not been structurally resolved since February 2023. Three years of emergency patching via temporary agreements with national operators has not produced a durable solution. North Dade Landfill absorbs the overflow — and is now projected to reach capacity approximately 2026. The structural accountability target: a procurement process that selected a single combustion operator for a 40-year contract with no facility backup or ACM alternative.
Severity: CriticalPain 2 — Structural Financial Deficit ($39M / Year)
The Collections Fund’s $39M structural deficit is not a budget anomaly — it is the predictable output of a cost architecture that has not kept pace with inflation, population growth, or post-RRF operational changes. The fee increase from $509 to $547/HH is insufficient to close the gap without ongoing Disposal Fund support. The structural accountability target: a rate structure that was not indexed to operational cost growth, and a reliance on landfill gate revenues that will evaporate as both landfills close.
Severity: CriticalPain 3 — Dual Landfill Closure Convergence
North Dade (~2026) and South Dade (~2030) are projected to reach capacity within 4 years of each other. This is not the gradual decline of one ageing facility — it is the simultaneous near-term decommissioning of both primary disposal assets. Combined closure cost: ~$50M initial. Revenue loss: $50M+/yr. Post-closure monitoring: 30 years. The structural accountability target: the absence of any long-term disposal capacity planning that responded to the RRF’s 40-year operational life with a parallel replacement strategy.
Severity: CriticalPain 4 — PFAS Crisis: Groundwater, Drinking Water, and CERCLA Activation
Miami is ranked the 3rd most PFAS-contaminated groundwater city in the US (FIU study, December 2024). Miami drinking water shows PFOS at 18.98 ppt — 4.7× the EPA April 2024 CERCLA limit of 4 ppt. Both county landfills are adjacent to sensitive groundwater zones. Landfill leachate is a primary PFAS transport pathway. The April 2024 CERCLA hazardous substance designation for PFOA and PFOS creates retroactive operator liability for parties that accepted PFAS-containing material. The structural accountability target: decades of landfill acceptance of PFAS-containing material in proximity to South Florida’s shallow water table with insufficient monitoring and remediation investment.
Severity: CriticalPain 5 — WTE Replacement Siting Conflict and Community Opposition
The proposed WTE replacement faces documented community opposition at all three candidate sites. Doral residents — already traumatised by the February 2023 fire — are resistant to any siting at the original location. Medley and Opa-Locka West Airport face opposition from adjacent residential communities and environmental advocates (Florida Rising). Three years of site review with no confirmed selection reflects the structural difficulty of siting a combustion facility in a densely populated South Florida county. The structural accountability target: a replacement procurement that replicates the same combustion technology that failed, in the same market environment that has already demonstrated community resistance.
Severity: HighPain 6 — Zero Waste Goal Gap
Miami-Dade’s 2021 Climate Action Strategy set a target of reducing per-capita landfill feedstock by 50% by 2030. The county generates more than twice the national per-capita average (4.9 lbs/person/day nationally; Miami-Dade: 10+ lbs/person/day). With no large-scale diversion infrastructure in place and both landfills approaching capacity, the county is structurally unable to meet its own 2030 target under the current system. The Zero Waste Master Plan expected in 2026 has no technology platform capable of delivering the required scale reduction. The structural accountability target: goal-setting without corresponding industrial infrastructure commitment.
Severity: HighPain 7 — Climate Vulnerability and Landfill Environmental Exposure
Miami-Dade is among the most climate-vulnerable large counties in the United States. Both landfills are in proximity to sensitive coastal and groundwater zones within South Florida’s low-elevation limestone karst aquifer system. As sea level rises and hurricane intensity increases, the county’s PFAS leachate liability exposure and physical landfill integrity risk will compound. The structural accountability target: a feedstock management architecture that relies on unlined or partially lined landfill cells in a region projected for 1–2 feet of sea level rise by 2060, with zero operational exit pathway.
Severity: HighMiami-Dade faces seven concurrent pain points — capacity collapse, financial deficit, dual landfill convergence, PFAS crisis, WTE siting conflict, Zero Waste goal gap, and climate vulnerability. None of these is addressable by the proposed WTE replacement. A new combustion facility would restore some disposal capacity while perpetuating or worsening five of the remaining six pain points. The ACM deployment directly addresses all seven: capacity (deployment at scale), financial (Revenue Stack + Circular Royalty™), landfills (diversion + Exogenesis), PFAS (molecular destruction), siting (no combustion = community acceptance), Zero Waste (Total Material Conversion), and climate (10-acre facility, no leachate, no sea-level exposure).
10Regulatory Capture
Regulatory capture in Miami-Dade’s feedstock management market operates through three mechanisms: statutory design that advantages combustion, procurement architecture that favours incumbents, and definitional frameworks that have historically excluded ACM from the market entirely. This section documents how incumbent operator interests have shaped the regulatory environment — not as an adversarial finding, but as an analytical explanation of why the market has not organically produced ACM solutions despite the availability of superior technology.
Florida §403.706(4)(a) — The WTE Recycling Credit Mechanism
| Capture Mechanism | How It Works | Incumbent Beneficiary | ACM Impact |
|---|---|---|---|
| §403.706(4)(a) WTE Credit | 1 MWh from combustion = 1 ton recycling credit. Counties meeting recycling goals via WTE have no incentive to build materials recovery infrastructure. | Combustion operators (Covanta/Reworld, WM, WIN Waste) | ACM’s 42–45% material recovery receives no statutory credit equivalent. ACM must achieve separate FDEP determination for equivalent classification. |
| Solid Waste Facility Definition (§403.703(36)) | Broad definition captures any facility that receives, stores, alters, or processes solid waste — including potential ACM facilities if feedstock is classified as solid waste. Default classification triggers FDEP permitting jurisdiction. | FDEP (regulatory authority) and incumbent operators with established permit relationships | ACM classification as manufacturing requires proactive FDEP engagement. Default classification as solid waste processing facility is the incumbent path of least resistance. |
| WTE Replacement Procurement Design | Design Criteria Professional/Owner’s Representative procurement (R-1096-23) is structured for combustion-based technology. AtkinsRealis has WTE design expertise. Preliminary permit sites all selected based on WTE footprint and airsheds. | AtkinsRealis · Combustion-experienced construction firms · WM, Republic, Reworld (potential O&M bidders) | ACM is not in scope for the current procurement design. Entry requires either a separate competitive solicitation or a county decision to redirect the procurement before site confirmation. |
| Chapter 15 Hauler Permit Framework | Permits all private haulers operating in Miami-Dade. Establishes the regulatory incumbency of existing hauler relationships with DSWM. | WM, Republic, and established independent haulers with long-standing permit relationships | ACM-neutral — Chapter 15 permits transition to Feedstock Hauler authorisation without structural change. This is one capture mechanism that does not disadvantage ACM entry. |
Miami-Dade’s regulatory framework systematically advantages combustion over Advanced Circular Manufacturing through three mechanisms: the WTE recycling credit, the solid waste facility default classification, and the combustion-oriented WTE replacement procurement design. None of these mechanisms requires legislative change to overcome — each is addressable through pre-application FDEP engagement, ACM manufacturing classification, and a county decision to redirect or supplement the WTE procurement before site confirmation. The regulatory capture is real, documented, and surmountable.
11Goals vs. Reality
Miami-Dade has set ambitious feedstock management and environmental goals across multiple policy frameworks. This section compares each stated goal against current measured performance and the structural trajectory under existing architecture. The finding across all goals is consistent: current infrastructure is not capable of delivering any of the stated targets.
Current per-capita generation is more than twice the national average and there is no large-scale diversion infrastructure in place or under construction. The RRF’s closure removed 1 million tons/year of non-landfill processing (not true diversion, but disposal capacity that extended landfill life). The proposed WTE replacement would restore disposal capacity without reducing per-capita landfill volumes, as the WTE itself counts as disposal, not diversion.
Zero Waste is an aspirational goal. The Zero Waste Master Plan will provide recommendations — but without a technology platform capable of converting feedstock streams into manufactured products at scale, no Zero Waste plan can achieve its targets. Miami-Dade generates 2× the national per-capita average. Zero Waste requires Total Material Conversion — the exact outcome ACM is designed to achieve.
With the RRF permanently closed, Miami-Dade has lost the primary mechanism by which it generated WTE recycling credits under §403.706(4)(a). The county’s statutory recycling compliance position has structurally deteriorated since February 2023. A WTE replacement would restore these credits; an ACM deployment would require separate statutory determination but would achieve materially higher actual material recovery (42–45%) than any combustion system has ever achieved.
As of March 2026, no site has been confirmed. No construction contract has been executed. Community opposition has been documented at all three candidate sites. The procurement design (AtkinsRealis PSA) is for a combustion-based facility. The gap between the BCC’s September 2023 vote and any operational replacement is estimated at 8–12+ years for a greenfield combustion facility. North Dade Landfill is projected to reach capacity in approximately 2026.
A new combustion-based WTE facility — even with modern emissions controls — is structurally incompatible with a near-zero-emissions processing goal. Combustion produces regulated stack emissions, bottom ash requiring landfill disposal, and significant CO₂e contribution. Miami-Dade cannot simultaneously pursue a near-zero emissions climate strategy and build a new combustion facility as its primary feedstock management infrastructure.
Miami-Dade has set five material goals for its feedstock management and environmental performance — and is tracking away from every single one under the current and proposed system architecture. The common denominator across all five failures is the same: a system built on combustion and landfill disposal cannot achieve near-zero emissions, Zero Waste, 50% per-capita reduction, genuine recycling compliance, or capacity replacement within the required timeframe. ACM achieves all five. This is not a coincidence — it is the architectural consequence of Total Material Conversion as a design principle.
12Cost Analysis — Facility-Weighted Disposal Cost (FWDC)
The Facility-Weighted Disposal Cost (FWDC) is the Carbotura benchmark against which the TMC Fee is calibrated. The FWDC represents the weighted average per-ton cost of feedstock management across all active disposal streams in Miami-Dade, based on publicly available fee schedules and estimated stream weightings. The FWDC is the commercial baseline for demonstrating that the TMC Fee is competitive with or below current disposal costs.
Stream-Level Cost Components
| Stream | Est. Weight (%) | Gate Fee (/ton) | Transfer Fee (/ton) | All-In Cost (/ton) | Weighted Cost | Conf. |
|---|---|---|---|---|---|---|
| MSW — Residential (contract) | ~45% | $16.28 | $16.66 | $32.94 | $14.82 | HIGH — rate MED — weight |
| MSW — Commercial (non-contract) | ~35% | $16.91 | $16.91 | $33.82 | $11.84 | HIGH — rate MED — weight |
| Special waste / bulky (premium) | ~10% | $16.91 | $16.91 | $33.82 + $87.85/load | ~$38–$45/ton est. | HIGH — rate LOW — per-ton conversion |
| Overflow (emergency agreement) | ~10% | Market rate est. $40–$55/ton | Transport additional | ~$50–$70/ton est. | ~$5–$7/ton | LOW — no public rate |
| FWDC — Weighted Average | 100% | Σ(stream cost × weight) | ~$35–$42/ton | MED overall | ||
FWDC derivation: Σ($32.94 × 0.45) + ($33.82 × 0.35) + (~$42 × 0.10) + (~$60 × 0.10) = $14.82 + $11.84 + $4.20 + $6.00 = $36.86/ton midpoint. Range: $35–$42/ton reflecting uncertainty in special waste and overflow cost components. This is a MED-confidence estimate. Full FWDC refinement requires DSWM data room access to confirm stream tonnage weights and non-contract disposal arrangements.
Per-Household Cost Analysis
| Cost Element | Annual Amount | Per Month | Notes |
|---|---|---|---|
| Collection service fee (non-ad valorem) | $547.00 | $45.58 | FY 2025–26. Full-service household (garbage + trash + TRC access + recycling) |
| Marginal disposal cost (collection share) | Embedded | Embedded | Disposal costs allocated within total DSWM operating budget, not separately billed to households |
| Effective household cost | $547/yr | $45.58/mo | Does not include future rate increases required to address $39M structural deficit or landfill closure costs |
FWDC vs. ACM TMC Fee — Baseline Comparison
| Cost Benchmark | Per-Ton Amount | Notes |
|---|---|---|
| FWDC (current weighted average) | ~$35–$42/ton | All-in cost including gate + transfer. Does not include overhead allocation or true cost of operation. |
| ACM TMC Fee (Carbotura) | ≤ FWDC | TMC Fee structured to be competitive with or below current per-ton disposal cost. Exact rate subject to COA negotiation. |
| Additional revenue: Circular Royalty™ | Month 13+ | Per-ton conversion royalty paid by Carbotura to Miami-Dade from manufactured materials revenue. Converts a cost line to a revenue line. |
| Net cost advantage of ACM | Positive from Day 1 | Cost parity at TMC Fee. Revenue advantage from Circular Royalty™ month 13. Capital obligation savings: ~$1B+ (WTE replacement eliminated). |
Miami-Dade’s FWDC of approximately $35–$42/ton (gate + transfer, weighted across all streams) is the commercial benchmark the ACM TMC Fee must meet or beat. It does. But the cost analysis understates the ACM case: the TMC Fee comparison is only Day 1. From month 13, the Circular Royalty™ shifts Miami-Dade’s cost position to a net revenue position. Over 30 years at 2,000 TPD, the cumulative financial advantage of ACM over the current system is not a cost reduction — it is a fundamental inversion of Miami-Dade’s financial relationship with its own feedstock stream.
13Financial Liabilities
This section documents Miami-Dade’s full spectrum of disclosed, undisclosed, and contingent financial liabilities associated with its legacy feedstock management system across seven sub-categories (A–G). These liabilities are assessed individually and aggregated to produce a total liability exposure estimate. GASB accounting standards applicable to each liability category are noted where relevant.
Aggregate Liability Exposure Estimate
| Liability (Sub-section) | Amount | Conf. | GASB Standard |
|---|---|---|---|
| A — Landfill Closure Capital | ~$50M | HIGH | GASB 18 |
| B — Post-Closure Monitoring (30yr) | ~$40–$100M est. | LOW | GASB 18 |
| C — RRF Fire Closure & Settlement | Unquantified | MED | GASB 49 |
| D — PFAS Environmental Liability | Unquantified — potentially >$100M | HIGH — CERCLA activation | GASB 49 |
| E — Disposal Revenue Loss (10yr) | >$500M cumulative | HIGH | Enterprise Fund / Cash Flow |
| F — WTE Replacement Capital | ~$800M–$1.5B+ | LOW — uncommitted | GASB 60 (if county-owned) |
| G — Collections Fund Deficit (5yr) | ~$195M+ if unresolved | HIGH | Enterprise Fund |
| Aggregate 10-Year Exposure | >$1.7B | MED overall | Multiple GASB standards |
Aggregate exposure is a conservative estimate excluding PFAS remediation quantification and assuming mid-range WTE capital. The ACM deployment under Carbotura’s BOO model eliminates sub-section F entirely, defers A and B through feedstock diversion and Exogenesis, reduces D through PFAS destruction at molecular level, replaces E through Circular Royalty™ revenue, and resolves G through Revenue Stack support of the Collections Fund from year 2.
Miami-Dade’s aggregate 10-year liability exposure from its legacy feedstock management system exceeds $1.7 billion by conservative estimate — and that figure excludes PFAS remediation costs that are currently unquantified but CERCLA-activated. The Carbotura ACM deployment under BOO eliminates the WTE capital commitment, defers or eliminates landfill closure obligations through diversion and Exogenesis, creates a PFAS destruction pathway, and generates Circular Royalty™ revenue to resolve the structural deficit. On a net present value basis over 30 years, the ACM deployment converts a >$1.7 billion liability stack into a multi-billion-dollar Revenue Stack. The liability case for ACM is, if anything, stronger than the revenue case.
