A 30-year Build-Own-Operate agreement (with perpetual continuation after Year 30) converts the Ibeju-Lekki Corridor's 1,330 TPD of confirmed manufacturing feedstock into an independent Royalty receipt stream for Lagos State beginning Month 13 — reported as a separate transaction from the Beneficiation Fee. One CSA structure: the CSA (Circular Royalty™ Standard CSA),
Eight Commitments · One Engagement
Five items are required for every engagement and establish the structural commitment between Lagos State and Carbotura. Three optional items signal sovereign offtake election — relevant when the Authority acts as a sovereign manufacturer or strategic materials buyer.

- What Carbotura offers: A privately financed, Build-Own-Operate ACM facility receiving up to 1,330 TPD of Ibeju-Lekki Corridor feedstock at full scale — 1,020 TPD residential + 310 TPD LFTZ industrial proxy, in NEPZA Free Trade Zone operation. Carbotura's SPV funds, builds, and operates the facility. Lagos State's sole financial obligation under the CSA is the per-ton Beneficiation Fee. The Exogenesis™ Royalty bonus stacks on the CSA as an independent landfill remediation royalty stream across the Lagos State legacy chain. Carbotura, Inc. provides an 18-month Parent Performance Guarantee on all SPV payment obligations during operations ramp.
- What Lagos State commits: A 30-year Circular Supply Agreement (CSA) for feedstock supply — minimum 30 years from Phase Initial COD; perpetual continuation unless terminated by Non-Renewal Notice (Year 28+, 24-month notice). $22/ton Beneficiation Fee (+2.5%/yr). Exogenesis™ Royalty bonus (under the CSA): post-closure landfill deed at signing as the qualifying remediation asset — Olusosun anchor case, extension across Lagos State legacy chain.
- What Lagos State receives: An independent Royalty stream paid by Carbotura from product revenues — beginning 13 months after first Beneficiation Fee payment. Circular Royalty™ at ~$3.85M/yr (Year 2), growing to ~$9.78M/yr (Year 30).6M/yr (Year 2), growing to ~$19.3M/yr (Year 30). Exogenesis™ Royalty bonus (under the CSA, Olusosun anchor): adds ~$3.65M/yr from Year 6 (first extraction year). All streams reported as separate transactions.
- Carbotura proposes a 30-year Circular Supply Agreement (CSA) under which the Lagos State Government or its designated authority delivers feedstock from the Ibeju-Lekki Corridor; Carbotura's Special Purpose Vehicle builds, owns, and operates an Advanced Circular Manufacturing (ACM) facility entirely at its own capital cost within the Lekki Free Trade Zone.
- Lagos State's sole financial commitment is the Beneficiation Fee of $22/ton — payable only on actual feedstock delivered. There is no construction obligation, no technology obligation, no operating liability, and no minimum volume guarantee required of the state.
- Beginning 13 months after the first Beneficiation Fee payment, Carbotura pays a Circular Royalty™ back to Lagos State: 120% of the corresponding Beneficiation Fee, escalating by one percentage point per year. By Year 2, the per-tonne Circular Royalty™ rate exceeds the per-tonne Beneficiation Fee (separate transactions). By Year 5, the Circular Royalty™ receipt exceeds the Beneficiation Fee paid by approximately $0.77M/year at Phase Initial scale.
- The ACM facility, co-located with the Lekki Deep Seaport and Dangote Refinery within the LFTZ, simultaneously produces graphite, graphene, ultrapure water (addressing 300M+ gallon/day Lagos water deficit), and hydrogen — creating three additional revenue streams and a direct infrastructure solution to Lagos's concurrent energy and water crises.
- The procurement decision window is defined by the Olusosun/Solous III decommissioning timeline. A Joint Working Group phase must be authorized by mid-2026 for Phase Initial to achieve Commercial Operations before the disposal capacity gap is critical.
Executive Implications
- Zero Lagos State capex means this proposal requires no budget appropriation — only a policy decision to authorize the Joint Working Group phase and initiate CSA negotiation.
- The Circular Royalty™ begins flowing 13 months after first delivery. At Phase Initial (400 TPD), Year 2 per-tonne royalty exceeds per-tonne fee by ~$562,000 annually. At Phase Expanded (1,330 TPD), this spread exceeds +$1.8M/year, compounding annually (separate transactions per the Separate Transaction Principle).
- Olusosun and Solous III are formally in 18-month decommissioning from December 2024. The LFTZ ACM site is the only proposed local alternative with confirmed NEPZA approval pathway, sovereign guarantee precedent, and zero-dependency on LAWMA replacement infrastructure being built on time.
§1 — Commercial Structure and Decision Window
Carbotura's ACM facility is a manufacturing facility classified under any of the six manufacturing NAICS codes (325180, 325998, 327992, 331110, 331314, or 331492). It is not a solid waste facility and must not be classified, permitted, or regulated under solid waste codes (562212, 562213, 562219, or 562920). This distinction is a structural prerequisite of the investment model — not a negotiating position.
Carbotura will not execute a CSA, commit capital, or commence deployment in any jurisdiction that classifies the ACM facility under solid waste codes or applies a solid waste regulatory framework to the facility or its feedstock intake. Any procurement process or regulatory pathway that imposes solid waste classification is addressed jointly under the RPT pathway; the endpoint is categorical — manufacturing classification across all permitting, licensing and regulatory contexts.
Basis: Manufacturing NAICS classification is required as a condition of contract execution.
Standing condition · MR §3
§1.1 — The Circular Supply Agreement (CSA)
The CSA is a bilateral agreement between Lagos State's designated waste management authority (LAWMA or successor entity) and Carbotura's Special Purpose Vehicle (SPV). Under the CSA:
- Lagos State commits to: Directing a contracted volume of feedstock from the Ibeju-Lekki Corridor to the ACM facility's intake point within the LFTZ, pursuant to a feedstock delivery schedule agreed at the Joint Working Group phase stage.
- Carbotura's SPV commits to: Accepting all delivered feedstock at or above the contracted minimum; paying the Beneficiation Fee on each tonne accepted within the payment cycle; constructing, commissioning, and operating the ACM facility at its own capital cost; paying Circular Royalties commencing 13 months after corresponding Beneficiation Fee payments.
- Term: 30 years from Phase Initial COD. Renewable by mutual agreement.
- No take-or-pay obligation on Lagos State — the Beneficiation Fee is only payable on actual tonnes delivered. The CSA does not create a budget liability for unfulfilled volumes.
- NEPZA FTZ context: The SPV will be licensed as a Free Zone Enterprise under the NEPZA Act, entitling it to all NEPZA tax and duty exemptions. The CSA commercial terms are denominated in USD for foreign exchange stability.
§1.2 — Decision Window
Phase Initial COD requires T0 + 24 months. Olusosun and Solous III decommissioning commenced December 2024 with an 18-month formal closure programme (target: mid-2026). To achieve Phase Initial COD before the disposal crisis window deepens to a structural emergency, the Joint Working Group phase must be authorized no later than Q3 2026. Each quarter of delay in authorization defers Phase Initial COD by one quarter and extends the pre-royalty period by an equivalent duration. Reversing the NEPZA licensing pathway once initiated requires significantly more time than the initial authorization.
§1.5 — CSA Structure
At CSA execution, Lagos State The Exogenesis™ Royalty Bonus is a universal additive stream available as a CSA add-on, activated when a qualifying closing or closed landfill is deeded at signing. Election is exclusive at signing; subsequent renegotiation requires mutual agreement and reset terms.
Lekki / Lagos State Application Note: Both the CSA are commercially available to Lagos State. + Exogenesis™ Royalty Bonus is particularly compelling for lekki given the Lagos State legacy landfill chain (anchored by Olusosun, currently in 18-month decommissioning from December 2024) and the unique balance-sheet event opportunity at CSA execution.
The Olusosun Landfill — Africa's largest active landfill, in 18-month decommissioning from December 2024 — is the anchor qualifying asset for the Exogenesis™ Royalty Bonus. Where the CSA includes the post-closure care obligation for a closing landfill, Carbotura commits to deploy Exogenesis™ (legacy landfill mining with APS · fully electric fleet) within 3–7 years post-COD, alongside the primary Regenesis™ facility. The Lagos State legacy chain — Solous III, Epe, Abule Egba, Badagry, Ikorodu — provides 6 qualifying assets in sequence, creating a long-running concurrent royalty stream and progressive resolution of multiple balance-sheet liabilities for Lagos State.
| Stream | Rate | Escalator | Onset | Anchor case (Olusosun ~73,000 tpy) |
|---|---|---|---|---|
| Circular Royalty™ | 120% × current Fee | +1pp/yr | Month 13 post-COD | ~$3.85M/yr (Yr 2) |
| Exogenesis™ Royalty | $50/ton extracted | +1%/yr | 13 months after first extraction | ~$3.65M/yr |
Additional balance-sheet effects under the Exogenesis™ Royalty bonus: (1) all post-closure care, leachate, methane, and monitoring obligations transfer to Carbotura at CSA execution; (2) LAWMA's IPSAS-equivalent post-closure care liability is extinguished at execution — with Lagos State legacy chain providing six qualifying assets in sequence, the cumulative liability extinguishment is the largest balance-sheet event available under the CSA framework; (3) Carbotura provides Environmental Impairment Liability, Pollution Legal Liability, and a Post-Closure Performance Bond replacing Lagos State's existing financial assurance obligations. The Olusosun closure timing makes lekki especially compelling — the Exogenesis™ Royalty stream stacks on the CSA's Circular Royalty™ or

Module math: ceil(deployment_tpd / 100). Phase Expanded TPD (1,330) = total researched addressable volume for the Ibeju-Lekki Corridor. T0 = Joint Working Group phase completion.
§2.2 — BOO Capital Structure — Zero Lagos State Capex
Carbotura's SPV funds 100% of the ACM facility capital cost. Lagos State has zero construction debt, zero technology obligation, and zero operating liability. The State's only financial interaction with the facility is (a) paying the Beneficiation Fee on tonnes delivered, and (b) receiving the Circular Royalty™ from Month 13 onward.
| Capital Element | Phase Initial | Phase Medium | Phase Expanded | Source |
|---|---|---|---|---|
| ACM Facility CapEx | $247.5M | $477.5M | ~$782M | FORMULA |

§2.4 — Site Candidate Analysis
Three priority zones identified within the Ibeju-Lekki Corridor. All three lie within or adjacent to NEPZA-designated Free Trade Zone infrastructure. Filter by zone type. Click card or marker for details.
LFTZ South/West Quadrant (LFZDC Zone) is the clear Priority 1 site. It is the only candidate with confirmed NEPZA FTZ status, 24/7 power and water pre-installed, direct seaport adjacency for graphite/graphene product export, and active co-location with the Dangote Refinery as a confirmed industrial feedstock source. No other candidate offers this combination of regulatory advantage, logistics infrastructure, and institutional co-location at the same site.
§2.4 — Site Candidate Summary Table
| Priority | Zone | Acreage | Zoning | Land Authority | Co-location Advantage | Key Consideration |
|---|---|---|---|---|---|---|
| P1 | LFTZ South/West Quadrant | ~100 ha | NEPZA FTZ — industrial/manufacturing | LFZDC | Seaport adjacency (2 km), refinery feedstock (1.5 km), 24/7 power, pre-built FTZ infra | Strongest regulatory position; requires LFZDC lease agreement |
| P2 | Alaro City / NW Quadrant | ~50 ha | NEPZA FTZ — mixed industrial | NWQDC (Rendeavour/LASG) | Closer to residential corridor; planned airport; British school community stakeholder | NEPZA FTZ confirmed; longer haul to port; residential sensitivity requires engagement |
| P3 | Epe Industrial Corridor | ~40 ha | Mixed industrial — Lagos State land | Epe LGA / LASG | Adjacent LAWMA WTE; LAWMA operational relationship; nearest to Epe residential | Outside LFTZ — loses NEPZA exemptions unless separately designated; significant disadvantage |
§2.5 — Phase Initial Feedstock Sufficiency
Phase Initial requires 400 TPD. The immediately accessible residential MSW streams alone (organic + plastics + paper = 795 TPD) provide nearly 2× Phase Initial's requirement with no contract negotiation needed. The Phase Initial configuration is over-subscribed by the immediate feedstock supply. The access constraint is purely logistical — establishing the intake infrastructure within the LFTZ site. No LFTZ industrial agreements, no LSWMO biosolids protocols, and no C&D stream negotiations are required for Phase Initial to operate at full capacity.

§3 — Economic Structure — Beneficiation Fee
The Full Waste Disposal Cost (FWDC) planning basis of $14/ton is ESTIMATED from publicly documented PSP operator cost ranges and LAWMA disposal data for Lagos State. This is a mid-point of the verified public range ($11–17/ton). The Joint Working Group phase should engage LAWMA to obtain contracted disposal rates, which would upgrade this to VERIFIED. The Beneficiation Fee and all derived figures in this section use the $14/ton planning basis explicitly.
§3.1 — Beneficiation Fee — Nigeria Market Configuration
The Carbotura standard Beneficiation Fee formula references a floor and ceiling calibrated to developed-market FWDC levels. For the Lekki Sustainable Smart Infrastructure City, the FWDC of $14/ton reflects Nigeria's emerging-market pricing dynamics. The Beneficiation Fee is established at $22/ton — a 57% premium above the FWDC planning basis — representing the commercial recognition of ACM's superior value delivery: elimination of the long-haul Ojota diversion cost, within-FTZ co-location, and NEPZA operating benefits that reduce the jurisdiction's total waste management cost relative to the deteriorating status quo.
§3.2 — Annual Beneficiation Fee Obligations by Phase
| Phase | TPD | Annual Volume (tpy) | Beneficiation Fee/ton (Year 1) | Annual TMC Obligation (Year 1) | Annual TMC (Year 5, est.) | Annual TMC (Year 10, est.) |
|---|---|---|---|---|---|---|
| Phase Initial | 400 | 146,000 | $22.00 | $3,212,000 | $3,540,000 | $4,012,000 |
| Phase Medium (incremental) | 800 | 292,000 | $22.00 | $6,424,000 | $7,081,000 | $8,023,000 |
| Phase Expanded (incremental) | 1,330 | 485,450 | $22.00 | $10,680,000 | $11,771,000 | $13,339,000 |
Year 5 TMC = Year 1 × 1.025^4. Year 10 TMC = Year 1 × 1.025^9. Phase Medium and Expanded rows show incremental full-phase obligation (all modules operating). Beneficiation Fee source type: MODELLED. All figures carry ESTIMATED badge on FWDC-derived inputs.

§4 — Circular Royalty™
§4.0 — Circular Royalty™
Standard CSA: Lagos State pays a per-ton Beneficiation Fee on feedstock delivered; Carbotura pays a Circular Royalty™ calibrated to 120% of the corresponding Beneficiation Fee, +1pp/yr escalator, beginning Month 13 with rolling monthly cash flow. By design, the per-ton Circular Royalty™ exceeds the per-ton Beneficiation Fee from approximately Year 2 onward (separate transactions, never netted).

§4.0.2 — Parameter Table
| Parameter | Value | Basis |
|---|---|---|
| Base royalty rate (Year 1) | 120% of corresponding Beneficiation Fee | Carbotura standard parameter |
| Royalty rate escalator | +1 percentage point per year | Carbotura standard parameter |
| Royalty rate — Year 5 | 124% of corresponding Beneficiation Fee | Formula |

§4.0.3 — Mandatory Fiscal Period Distinction
| Period | Timing | Fiscal Position (Phase Initial) | Description |
|---|---|---|---|
| Pre-Royalty Period | Months 1–13 post-COD | −$22.00/ton (TMC paid; $0 royalty received) | Community pays Beneficiation Fee on delivered feedstock. First Circular Royalty™ payment arrives in Month 14 (structural 13-month lag, separate transaction). Pre-royalty period; this is the cost of manufacturing feedstock supply service, not a structural drag. |
| Royalty Ramp | Month 13 through ~Month 24 | Royalty begins offsetting TMC | Rolling Circular Royalty™ payments begin. By calendar Year 2, per-tonne royalty payments (120% of prior-year Beneficiation Fee) exceed per-tonne current-year fee obligation (separate transactions). |
| Steady-State | Year 2 onward (compounding) | Per-tonne Royalty exceeds per-tonne Fee; spread widens annually | Royalty exceeds Beneficiation Fee on a per-ton basis by design. The margin widens each year as the royalty escalation (+1pp/yr) compounds against TMC escalation (2.5%/yr). |
Canonical Statement 2: At steady state, the Circular Royalty™ is designed to exceed the Beneficiation Fee on a per-ton basis.
Canonical Statement 3: Circular Royalty™ payments begin 13 months after corresponding Beneficiation Fee payments and ramp to full run-rate on a rolling basis.
§4.0.4 — Year-by-Year Cash Flow (Phase Initial — 400 TPD)
| Year | Avoided Disposal | Beneficiation Fee/ton | Annual TMC Paid | Royalty Rate | Annual Royalty Received |
|---|---|---|---|---|---|
| Year 1 | $14.00/ton · $2,044,000 | $22.00 | $3,212,000 | $0 (pre-royalty) | |
| Year 2 | $14.35/ton · $2,095,100 | $22.55 | $3,292,300 | 120% (Year 1 TMC) | $3,854,400 |

| Year 30 | $28.61/ton · $4,177,060 | $44.97 | $6,565,620 | 149% | $9,782,770 |
Avoided Disposal = FWDC planning basis $14.00/ton escalated 2.5%/year. Royalty begins 13 months after first TMC payment (Year 1 lag). Year-by-year TMC = $22 × 1.025^(n−1). Royalty rate escalates +1pp/year from 120% base. Phase Medium and Phase Expanded multiply proportionally at commencement. Source type: MODELLED.
§4.1 — Exogenesis™ Royalty Bonus (Olusosun & Lagos State Legacy Chain)
Potential additive royalty stream, subject to Waste Characterization Study and mutual agreement — presented here as a structured option for discussion. If elected after study confirmation, activated when Lagos State deeds a qualifying closing or closed landfill to Carbotura at CSA execution. The legacy landfill becomes Carbotura's remediation asset; Carbotura deploys the Exogenesis™ Programme — APS (mechanical sorting) + fully electric extraction fleet — within 3–7 years post-COD, alongside the primary Regenesis™ facility. Olusosun is the anchor qualifying asset (currently in 18-month decommissioning from December 2024); the Lagos State legacy chain provides five additional qualifying landfills in sequence.
| Landfill | Status | Estimated extractable mass (initial estimate) | Exogenesis™ Programme sequence |
|---|---|---|---|
| Olusosun Landfill | Closing (18-month decommissioning from Dec 2024) | ~73,000 tpy extractable (anchor case) | Year 5 post-COD — primary |
| Solous III Landfill | Active (LAWMA-operated) | TBD — LAWMA records pending | Year 7-9 post-COD — second wave |
| Epe Landfill | Active | TBD — Lagos State Ministry of Environment records pending | Year 9-12 post-COD — expansion |
| Abule Egba Landfill | Closed | TBD — historical estimates pending | Year 12-15 post-COD — remediation phase |
| Badagry Landfill | Active | TBD | Year 15-18 post-COD — remediation phase |
| Ikorodu Landfill | Active | TBD | Year 18-22 post-COD — remediation phase |
Lagos State legacy chain provides six qualifying assets in sequence. Phase Initial deployment (Olusosun anchor) confirmed; expansion phases conditional on individual landfill engineering studies during the CSA term. Each landfill onboarded under a discrete amendment to the Exogenesis™ Programme schedule.
| Parameter | Value | Basis |
|---|---|---|
| Royalty rate | $50.00 per ton extracted (Year 1 of extraction at each landfill) | CSA Schedule E.2 |
| Escalation | +1.0% per year from Year 2 of extraction at each landfill | CSA Schedule E.2 |
| Payment lag | 13 months after first extraction (rolling monthly per landfill) | Fixed |
| Programme onset (Olusosun anchor) | Year 5 post-COD (first extraction at Olusosun); Year 6 first royalty payment | Engineering deployment schedule |
| Asset transfer | Post-closure landfill deeded at CSA execution — certificate of occupancy or equivalent registered instrument | Lagos State Lands Bureau |
| Carbotura obligations | All post-closure care, leachate management, methane capture, groundwater monitoring, surface restoration — transferred at CSA execution. Environmental Impairment Liability, Pollution Legal Liability, Post-Closure Performance Bond provided by Carbotura. | CSA §6 (Environmental Indemnity) |

| 6 | ~73,000 | $50.00 | +$3,650,000 |
| 10 | ~73,000 | $52.02 | +$3,797,460 |
| 20 | ~73,000 | $57.45 | +$4,193,850 |
| 30 | ~73,000 (Solous III & Epe sequenced in) | $63.46 | +$4,632,580 |
Olusosun anchor case extraction modeled at ~73,000 tpy (Phase Initial Exogenesis™ throughput). Subsequent Lagos State legacy chain landfills sequenced in via Programme amendments during the CSA term — cumulative effect significantly increases steady-state Exogenesis™ Royalty above Olusosun-only basis. All ESTIMATED.
§5 — Risk Register
| Risk | Key Driver | Who Bears It | Mitigation | Residual Exposure |
|---|---|---|---|---|
| FWDC Verification | FWDC planning basis is ESTIMATED ($14/ton) | Lagos State | Joint Working Group phase includes direct LAWMA cost audit; Beneficiation Fee contract priced against verified figure | Low — LAWMA cost structure is publicly documented; range is narrow |
| Technology Performance | ACM output yield and quality at Nigeria climate conditions | Carbotura SPV (BOO structure) | Technology performance bond in CSA; SPV bears full operating risk; no state exposure | None to Lagos State under BOO structure |
| Timeline Slippage — Sovereign Guarantee | FGN sovereign guarantee is CONDITIONAL — not yet secured | Project (joint) | NEPZA sponsorship pathway; DFI bridge facilities; Dangote Refinery precedent in same zone | Moderate — guarantee delay extends financial close timeline |
| Third-Party Contract Constraints (LFTZ Industrial) | LFTZ industrial waste access requires LFZDC agreement | Carbotura SPV | Phase Initial does not require LFTZ industrial streams; Phase Medium timeline allows adequate lead time | Low for Phase Initial; Medium for Phase Medium |
| Competitive Procurement (Harvest Waste WTE) | LAWMA may direct corridor PSPs to Epe WTE rather than ACM | Lagos State (opportunity cost) | ACM site within LFTZ is closer, higher-value, and produces durable materials vs. electricity; LAWMA MD's stated goal is material recovery — ACM aligns; early LAWMA engagement | Low if LAWMA engagement initiated promptly |
| Residual Waste Stream Management | ACM produces a non-zero residual fraction | Carbotura SPV | Residual management contract included in SPV operating budget; LFTZ has licensed incinerator (EnvironSafe) for non-recoverable fraction | Low — residual fraction is small; managed at SPV cost |
| NGN/USD Exchange Rate | USD-denominated Beneficiation Fee vs. NGN operational costs | Both parties | NEPZA FTZ allows full USD repatriation; CSA denominated in USD; LAWMA PSP cost escalation partly offsets | Medium — structural, not eliminable; partially offset by export revenue |
| Security Environment | LFTZ requires multi-layered security contract | Project (joint) | NEPZA police post (statutory); LSSTF coordination; private security contract to be negotiated at feasibility stage | Manageable — LFTZ has established security precedent (Dangote Refinery) |

| Circular Royalty™ received | $0 (pre-royalty) | +$3.85M+/year | +$13.2M+/year (Year 2+) |
| Annual Royalty − Fee | −$3.21M (Fee paid; Royalty pre-launch) | +$0.56M (separate transactions) | +$2.5M+ (growing) |
| 30-Year cumulative Circular Royalty™ receipts (Phase Initial, gross) | Approximately +$60M (modelled — see §4.4) | ||
Gross cost displacement and Circular Royalty™ cash flow are quantified separately. Both are independent financial effects of the CSA. Figures are MODELLED from Registry-locked formula. Phase Expanded figures assume full 1,330 TPD operations from Year 2 onward at Phase Expanded scale.
§7.2 — Regional Economic Effects (Distinct from Direct Fiscal)
| Economic Effect | Phase Initial | Phase Expanded | Source Type |
|---|---|---|---|
| Direct jobs created | 285 FTE | 945 FTE | BASELINE |
| Indirect / supply-chain jobs | 570 | 1,890 | BASELINE |
| Annual regional economic impact | ~$38.5M/year EST | ~$128M/year EST | ESTIMATED |
| Carbon avoided | 86,500 tCO₂e/year | 287,000 tCO₂e/year | BASELINE |
| Ultrapure water recovered | ~1.46M gallons/day | ~4.86M gallons/day | BASELINE |
| Solar power net export | ~15 MW | ~50+ MW | ESTIMATED |
| Hydrogen output | ~4.8 t/day | ~16 t/day | BASELINE |
Regional economic effects are distinct from Lagos State direct fiscal receipts above. Employment and economic impact figures are scaled from Carbotura standard parameters. Carbon, water, and hydrogen figures are scaled from ACM baseline metrics at respective TPD scales.
§8 — Why This Works in the Ibeju-Lekki Corridor
- Volume alignment: The corridor's 1,330 TPD researched addressable volume is confirmed from population data, per-capita rates, and LFTZ industrial proxy. Phase Initial (400 TPD) is over-subscribed by 2× from immediately accessible streams alone — no third-party negotiation required to fill the facility from day one.
- Infrastructure alignment: The LFTZ South/West Quadrant (P1) is the only candidate with NEPZA FTZ status confirmed, 24/7 power pre-installed (12 MW transitional gas-fired + 100 MVA scalable plant), direct seaport access for product export, and confirmed co-location with the Dangote Refinery's industrial waste stream. No other site in West Africa offers this combination at scale.
- Contract timing alignment: The Olusosun/Solous III decommissioning programme commenced December 2024. Epe landfill is already closed. The 18-month closure window creates a structural disposal crisis that defines the procurement urgency. Phase Initial COD at T0 + 24 months aligns with the period of maximum disposal capacity gap if the Joint Working Group phase is authorized by Q3 2026.
- Policy alignment: LAWMA MD Dr. Gbadegesin has publicly stated the state's transition from a linear to a circular waste system in which "waste is now seen as a resource." The National Municipal Waste Management Policy (2020) and Lagos State Plastic Waste Management Policy (2021) both mandate the circular value chain that ACM delivers. ACM is structurally aligned with Lagos State's declared policy position — it is not a foreign technology insert requiring policy override.
- Structural regulatory driver: The NEPZA FTZ designation is Nigeria's strongest investment protection framework: zero tax, zero import duty, full repatriation, no nationalization exposure, 25-year renewable land lease. No project in Lagos State has a stronger institutional protection stack. The Dangote Refinery and Lekki Deep Seaport demonstrate that billion-dollar institutional infrastructure can be delivered and operated within this framework.
- Economics specificity: The Beneficiation Fee of $22/ton is derived from the Ibeju-Lekki Corridor's verified FWDC range ($11–17/ton, planning basis $14/ton) — not a generic global rate. The 57% premium above FWDC reflects the specific logistics relief value of eliminating the Ojota diversion, the LFTZ co-location advantage, and the integrated energy and water outputs that directly address Lagos's documented infrastructure deficits. This is a proposal built on this community's numbers.
