What this document is
A single-page action instrument: the one thing to authorize before the Board adopts the Zero Waste Master Plan.
- 1The plan's own numbers leave ≈1.1M tons/yr landfill-bound even at full implementation.
- 2Carbotura fits on timing, procurement, and economics — matching the plan's own language.
- 3One action: execute an LOI/MOU before the plan is formally adopted.
Strategy 32: the residual layer the plan's own math leaves open Estrategia 32: la capa residual que las propias cifras del plan dejan abierta
The draft Zero Waste Master Plan (July 2026) is candid about its own limit: full implementation of all 31 strategies raises diversion from 36% to 77% — leaving an estimated ≈1,181,467 tons/yr still bound for landfill against the Mayor's 90%-by-2040 commitment, even as North Dade (2030) and South Dade (2032) landfills reach capacity. Engaging now, while the plan remains in its public-comment / pre-adoption window, is how a residual-conversion layer gets written into the plan itself. After adoption, it has to be negotiated separately. El borrador del Plan Maestro de Cero Residuos (julio 2026) es franco sobre su propio límite: la implementación completa de las 31 estrategias eleva la desviación del 36% al 77% — dejando un estimado de ≈1,181,467 toneladas/año aún destinadas a relleno sanitario frente al compromiso del 90% para 2040 de la Alcaldesa. Después de la adopción, tendría que negociarse por separado.
Carbotura was built for exactly this remaining stream. The ACM platform converts residual, waste-classified materials — the mixed stream left over after reduction, reuse, recycling, and composting have done their work — into manufactured outputs: synthetic graphite, graphene compounds, recovered minerals, plus net-positive ultrapure water. Not landfill, not incineration, not waste-to-energy — manufacturing. It competes with none of the plan's 31 strategies; it completes them, as the missing 32nd: the residual-conversion layer that carries the County from 77% toward its 90% goal. Carbotura fue construida exactamente para este flujo remanente. La plataforma ACM convierte materiales residuales clasificados como residuos en productos manufacturados: grafito sintético, compuestos de grafeno, minerales recuperados, más agua ultrapura neta positiva. No es relleno sanitario, ni incineración, ni conversión de residuos en energía — es manufactura.
The county's verified all-in disposal cost is $92.78/ton — $76.12/ton gate rate plus $16.66/ton transfer station fee per the Miami-Dade DSWM Disposal Facility Fee Schedule effective October 1, 2025. The ACM Beneficiation Fee is set at $88/ton — $4.78/ton below the verified current system cost, with zero county capital commitment. El costo de disposición verificado del condado es $92.78/ton. El Beneficiation Fee del ACM se fija en $88/ton — $4.78/ton por debajo del costo actual verificado.
Beginning 13 months after the first Beneficiation Fee payment, the county receives a rolling monthly Circular Royalty™ or ( A partir de 13 meses después del primer pago de Beneficiation Fee, el condado recibe una Circular Royalty™. La posición fiscal del condado se vuelve neta positiva a partir de ese momento.

ACM Modular Production Units are factory-manufactured and deployed under a Design for Manufacturability (DFM) model rather than conventional facility construction. Phase Initial reaches COD Q2 2028 — ahead of North Dade (2030) and South Dade (2032) reaching capacity.Las Unidades de Producción Modular ACM se fabrican en fábrica bajo un modelo de Diseño para Manufacturabilidad (DFM). La Fase Inicial alcanza el COD en el T2 2028 — antes de que North Dade (2030) y South Dade (2032) alcancen su capacidad.
The ZWMP repeatedly directs the County to solicit private-sector proposals for processing infrastructure, and Appendix E recommends evaluating third-party ownership and operating models. Carbotura's Circular Supply Agreement (CSA) is precisely such a structure — Build-Own-Operate, zero County capital.El PMCR dirige repetidamente al Condado a solicitar propuestas del sector privado para infraestructura de procesamiento, y el Apéndice E recomienda evaluar modelos de propiedad y operación de terceros. El Acuerdo de Suministro Circular (CSA) de Carbotura es precisamente esa estructura.
Under a CSA the County earns a Circular Royalty™ on the products manufactured from materials that today carry only a hauling and burial cost — extending the same regional economic case the plan already makes for its own organics investment (+2,300 person-years, +$670M regional output).Bajo un CSA, el Condado gana una Circular Royalty™ sobre los productos manufacturados a partir de materiales que hoy solo generan un costo de transporte y entierro.
The $92.78/ton FWDC is verified from the Miami-Dade DSWM Disposal Facility Fee Schedule effective October 1, 2025 ($76.12 gate + $16.66 transfer station). Year 1 gross cost displacement at Phase Initial: approximately $0.87M/yr. From Year 2, the royalty adds to this displacement.El FWDC de $92.78/ton está verificado en el Programa de Tarifas DSWM de Miami-Dade efectivo el 1 de octubre de 2025.
Not landfill, not incineration, not waste-to-energy — manufacturing (NAICS 31–33). Strategy 32 addresses precisely the residual the other 31 strategies do not reach, closing the gap toward the Mayor's 90%-by-2040 commitment.No es relleno sanitario, ni incineración, ni conversión de residuos en energía — es manufactura. La Estrategia 32 aborda precisamente el residual que las otras 31 estrategias no alcanzan.

FWDC $92.78/ton VERIFIED. BF $88/ton. Gross Displacement = ($92.78 − $88) × TPY. Royalty (Year n) = (120% + (n−1)pp) × that year’s Beneficiation Fee ($105.60/ton). At steady state, the Circular Royalty™ is designed to exceed the Beneficiation Fee on a per-ton basis. Circular Royalty™ payments begin 13 months after corresponding Beneficiation Fee payments and ramp to full run-rate on a rolling basis. Gross cost displacement is quantified separately from Circular Royalty™ cash flow per the Separate Transaction Principle.
