Nagpur, Maharashtra — 400 / 1,000 / 2,000 TPD नागपूर, महाराष्ट्र — ४०० / १,००० / २,००० टीपीडी
Prepared for Nagpur Municipal Corporation (NMC) · April 2026 · 30-Year Build-Own-Operate · IFRS Accounting
A 30-year BOO agreement converts Nagpur's 400 TPD of uncontracted manufacturing feedstock into a net revenue-positive position for NMC from Year 2 — with zero public capital expenditure.
३०-वर्षीय BOO करार नागपूरच्या ४०० टीपीडी असंबद्ध उत्पादन कच्च्या मालाला वर्ष २ पासून NMC साठी निव्वळ महसूल-सकारात्मक स्थितीत रूपांतरित करतो — शून्य सार्वजनिक भांडवली खर्चासह.
What This Means याचा अर्थ काय
- NMC bears no capital expenditure. Carbotura's SPV finances, constructs, owns, and operates the ACM facility in full. NMC's only financial obligation is the TMC Fee — a per-tonne manufacturing service fee paid on feedstock delivered. Construction risk, operating risk, and technology risk sit entirely with Carbotura's SPV.
- NMC becomes a royalty recipient from Month 13. Beginning 13 months after the first TMC Fee payment, NMC receives a Circular Royalty equal to 120% of the corresponding TMC Fee — growing at one percentage point per year for the 30-year term. At Phase Initial (400 TPD), NMC receives approximately Rs 147 crore (US$17.5 million) in Year 2 Circular Royalty, producing a net surplus over the TMC Fee of approximately Rs 21.6 crore ($2.6 million).
- The TMC Fee is set at the Carbotura standard floor. At $100/ton, Nagpur's TMC Fee is at the floor of Carbotura's standard parameters. This reflects a deliberate policy: in jurisdictions where municipal disposal costs are low, Carbotura accepts the floor rate because the long-term royalty stream — which grows with the TMC Fee base and rate simultaneously — produces a compelling 30-year NPV for both parties. NMC should model this as a 30-year royalty commitment, not a year-by-year cost comparison.
- The counterparty guarantee requirement is structurally necessary. At $247.5 million (Phase Initial) to $1.17 billion (Phase Expanded), the SPV financing structure requires a counterparty with a credit profile commensurate with the 30-year obligation. NMC, as a statutory body under the Maharashtra Municipal Corporations Act 1949, requires a sovereign backstop from the Government of India (MoHUA / Smart Cities Mission) and/or the State of Maharashtra (UDD/MSRDC), and a credit rating from S&P, Moody's, or Fitch, as a prerequisite to COA execution. The GoI is rated Baa3/BBB− by Moody's/S&P (2024). This requirement is not a barrier — it is an achievable structural condition that Carbotura will assist in establishing.
- Manufacturing classification is a prerequisite, not a preference. Carbotura's ACM facility cannot be permitted, licensed, or operated as a solid waste facility. Confirmation of manufacturing classification from the Maharashtra Pollution Control Board (MPCB) under the Environment Protection Act 1986 and SWM Rules 2016 is required before any capital commitment or COD milestone is triggered. This is the Classification Condition Precedent — detailed in §1.0 below.
Commercial Structure and Decision Window व्यावसायिक रचना आणि निर्णय विंडो
§1.0 — Classification Condition Precedent
Carbotura's commitment to this engagement is conditional on the Advanced Circular Manufacturing facility receiving and maintaining manufacturing facility classification — NAICS 335991, 325120, or 331410 — for all permitting, licensing, and regulatory purposes. Microwave Catalytic Reforming operates in an anoxic, oxygen-free, sub-atmospheric environment; it is mechanistically incompatible with combustion and is not a solid waste treatment process. The federal classification basis is the EPA RCRA Solid Waste Exclusion Petition is pending filing, April 2026. Should any authority apply NAICS 562213 or 562219 solid waste classification to the ACM facility or its feedstock intake streams, Carbotura will withdraw from the engagement without penalty. No capital commitment and no COD will proceed under misclassification.
§1.1 — Commercial Structure
The Circular Offtake Agreement (COA) is a 30-year Build-Own-Operate agreement between Nagpur Municipal Corporation and Carbotura's project Special Purpose Vehicle (SPV). The agreement establishes two bilateral obligations:
NMC's obligation: Deliver manufacturing feedstock to the ACM facility gate at the agreed daily volume. Pay the TMC Fee per tonne delivered on a monthly invoicing cycle. Ensure that the counterparty guarantee structure (sovereign backstop + international credit rating) is confirmed and maintained.
Carbotura SPV's obligation: Finance, design, construct, commission, own, and operate the ACM facility. Guarantee minimum throughput capacity. Pay the Circular Royalty to NMC's designated treasury account on a rolling monthly schedule beginning 13 months after first TMC Fee payment. Maintain the facility to designed specification for the full 30-year term.
Phase Initial COD is targeted at T0 + 24 months (Q3 2028, assuming T0 = Q3 2026). The Feasibility Study authorization must precede a Community Feasibility Study period of approximately 3 months. To hold the Q3 2028 COD, NMC must authorize the Community Feasibility Study no later than Q4 2026. Each quarter of delay defers the first Circular Royalty payment by one quarter and reduces the 30-year NPV by approximately Rs 73 crore ($8.7M) at an 8% discount rate.
§1.2 — Counterparty Guarantee Requirement
Given the 30-year term and the SPV CapEx of $247.5 million (Phase Initial) to $1.17 billion (Phase Expanded), Carbotura's SPV lenders require a counterparty credit profile consistent with investment-grade infrastructure financing. NMC, as a statutory municipal body, satisfies this requirement through one of the following guarantee structures:
- Pathway A — GoI Sovereign Backstop: Government of India guarantee via the Ministry of Housing and Urban Affairs (MoHUA) under the Smart Cities Mission or AMRUT 2.0 framework. GoI rated Baa3/BBB− (Moody's/S&P, 2024). Precedent: multiple PPP infrastructure projects with GoI sovereign backstop in the Smart Cities programme.
- Pathway B — Maharashtra State Guarantee: State government guarantee via Urban Development Department (UDD) or Maharashtra State Road Development Corporation (MSRDC). Maharashtra's fiscal position and AAA domestic credit rating (CRISIL) support this pathway.
- Pathway C — Multilateral DFI Co-Guarantee: AIIB, ADB, or World Bank Group (IFC/MIGA) guarantee framework for Indian municipal infrastructure. These institutions have active Indian urban infrastructure programmes and have financed analogous BOO transactions in Indian Smart Cities.
Carbotura will provide a guarantee structuring white paper as part of the Community Feasibility Study deliverable. NMC is not required to navigate this independently.

§2.4 — Site Candidate Analysis
Three candidate zones evaluated for ACM facility siting. Priority based on logistics convergence, land authority alignment, infrastructure co-location, and permitting pathway. Map markers show P1/P2/P3 sites; reference pins indicate primary feedstock convergence points.
Site candidates are provisional pending Community Feasibility Study land assessment and MPCB/MIDC consultation.
Site Candidate Summary Table
| Priority | Zone | Acreage Est. | Land Authority | Co-location Advantage | Key Consideration |
|---|---|---|---|---|---|
| P1 | Bhandewadi Complex | 5–8 acres available | Nagpur Municipal Corporation | All 1,300 TPD converges here daily; existing weighbridge; STP adjacency; BOO precedent (Hanjer, SMS Envocare) | Competing active projects on-site; NMC council resolution required for land allocation |
| P2 | MIDC Butibori Industrial Area | MIDC greenfield allocation | Maharashtra Industrial Development Corporation (MIDC) | Established industrial zone; SMS Envocare CHWTSDF and Butibori CETP on-site; NH-44 four-lane access; MIDC power infrastructure | 25 km from primary NMC feedstock; additional haul cost and logistics; MIDC allocation pathway separate from NMC |
| P3 | NMRDA Ring Road Corridor | TBD — NMRDA planning zones | Nagpur Improvement Trust (NIT) / NMRDA | Growth corridor; Phase Expanded feedstock aggregation point; strategic positioning for NMRDA ULB stream integration | Residential growth proximity (NIMBY risk); NMRDA planning approval required; feedstock haul distances variable |
Bhandewadi Complex is the Priority 1 site for Phase Initial. All 1,300 TPD of NMC feedstock converges at this location daily through an established collection and transport network. NMC owns the land. Multiple BOO precedents exist on-site. The weighbridge, internal roads, and utility connections are established. A 5–8 acre allocation within the 22-hectare site is achievable through NMC council resolution — the same mechanism used for the Bhumi Green and Ramky Enviro engagements. Phase Expanded may require MIDC Butibori as a secondary facility for regional feedstock aggregation.
§2.5 — Phase Initial Feedstock Sufficiency
Phase Initial at 400 TPD requires no third-party contract negotiation. The three IMMEDIATE-classified streams (mixed residual, plastic fraction, inerts/fines) total approximately 815 TPD — more than double the Phase Initial requirement. NMC is the sole counterparty. No competing BOT, CBG, or composting contract covers this volume. Phase Initial can proceed on signature of the COA alone.
Economic Structure — TMC Fee आर्थिक रचना — TMC शुल्क
§3.1 — FWDC Planning Basis
The Facility Waste Disposal Cost (FWDC) used for TMC Fee determination is the marginal landfill disposal rate for residual MSW in Nagpur, estimated at Rs 1,268/ton ($15.00/ton USD).
Source: NMC gate rate of Rs 750/ton documented by Times of India (April 2016), inflation-adjusted at approximately 6% per annum over 10 years to yield Rs ~1,343/ton (April 2026), rounded to Rs 1,268/ton ($15.00/ton at ₹84.50/USD). No publicly confirmed 2025 or 2026 NMC gate rate is available. A Community Feasibility Study will produce a VERIFIED FWDC through direct NMC financial disclosure. The VERIFIED FWDC will not change the TMC Fee — which is set at the Carbotura standard floor of $100/ton — but will confirm the full-system cost basis for the Avoided Disposal component of the fiscal model.
§3.2 — TMC Fee Formula
= MAX($100, MIN($150, $15.00 − $5.00))
= MAX($100, $10.00)
= $100.00 / tonne — Carbotura standard floor
Floor: $100/ton · Ceiling: $150/ton · Carbotura standard parameters. Nagpur's TMC Fee is at the floor because the estimated FWDC ($15/ton) is substantially below the floor. The TMC Fee is not derived from the FWDC but from the Carbotura standard floor. This is a structural feature, not a disadvantage: the 30-year Circular Royalty, which grows at both base and rate simultaneously, produces a materially superior return to NMC over the full term than continued low-cost landfill disposal.
§3.3 — Annual TMC Obligation by Phase
| Phase | TPD | TPY | Year 1 TMC Rate | Year 1 Annual Obligation | Year 2 Annual Obligation | Year 10 Annual Obligation |
|---|---|---|---|---|---|---|
| Phase Initial | 400 | 146,000 | $100/ton | $14,600,000 | $14,965,000 | $18,229,000 |
| Phase Medium | 1,000 | 365,000 | $100/ton | $36,500,000 | $37,413,000 | $45,572,000 |
| Phase Expanded | 2,000 | 730,000 | $100/ton | $73,000,000 | $74,825,000 | $91,144,000 |
TMC Fee escalates at 2.5% per annum. Year 10 calculated as $100 × 1.025⁹ = $124.89/ton. Values in USD. IFRS accounting — FWDC and TMC denominated in USD per COA; INR equivalent reportable at prevailing exchange rate.

§4.3 — Fiscal Period Distinction
| Period | Months | TMC Status | Royalty Status | NMC Net Position |
|---|---|---|---|---|
| Pre-royalty | 1–12 (Year 1) | Paid — $100/ton | $0 — accumulating | Negative (TMC only) |
| Royalty ramp | 13–24 (Year 2) | Paid — $102.50/ton | Begins — $120/ton (on Year 1 TMC) | Net positive from Month 13 |
| Steady state | Year 2 onward | Escalating 2.5%/yr | Escalating — rate + base simultaneously | Surplus grows every year |
Gross cost displacement is quantified separately from Circular Royalty cash flow. Full net fiscal position reflects both.
At steady state, the Circular Royalty is designed to exceed the TMC Fee on a per-ton basis.
Circular Royalty payments begin 13 months after corresponding TMC Fee payments and ramp to full run-rate on a rolling basis.

Why This Works in Nagpur हे नागपुरात का कार्य करते
- Volume alignment. Nagpur generates 1,300 TPD (verified). Phase Initial at 400 TPD addresses 31% of total generation — a modest, demonstrably achievable first deployment. The three IMMEDIATE-classified streams (mixed residual, plastics, inerts) provide 815 TPD of headroom above the Phase Initial requirement. There is no volume risk for Phase Initial.
- Infrastructure alignment. All NMC feedstock converges at Bhandewadi daily through an established, densified collection network. The Priority 1 site (Bhandewadi Complex) is NMC-owned, has an existing weighbridge, and has multiple active BOO/BOT precedents. Enclosed delivery from existing tipper fleet to ACM gate is operationally continuous with current practice. No new logistics infrastructure is required for Phase Initial.
- Contract timing alignment. NMC is under active NGT orders and Swachh Bharat Mission 2.0 compliance pressure — the 2024 dumpsite remediation deadline has passed and NMC is in active compliance action. The CBG plant (1,500 TPD) is in cold commissioning for the organic fraction. The uncontracted residual fraction (400–500 TPD) has no competing destination confirmed. The Phase Initial deployment window is open now.
- Policy alignment. ACM's manufacturing classification (§1.0 CCP) is fully consistent with India's policy direction: Swachh Bharat Mission 2.0 emphasises material recovery over disposal; EPR guidelines (2022) prioritise circular material flows; Smart Cities Mission has funded analogous industrial infrastructure BOO transactions. Maharashtra's environmental regulatory framework (MPCB under EPA 1986 / SWM Rules 2016) has an established pathway for manufacturing industrial activity consent. The CCP is a resolvable condition — not an obstacle.
- Regulatory driver. The Bhandewadi remediation mandate (NGT, SBM 2.0) creates an obligation independent of any commercial preference. The ACM facility at Priority 1 site is the highest-yield solution to the residual fraction compliance gap: it removes 400 TPD from the Bhandewadi burden immediately, generates royalty income to NMC rather than cost, and does so without NMC capital expenditure. No alternative solution offers this combination.
- Economics specificity. The TMC Fee of $100/ton is the Carbotura standard floor — set for jurisdictions where disposal costs are low and the royalty return is the primary value driver, not the avoided disposal cost. In Nagpur's case, the primary financial logic is: NMC commits to a manufacturing service fee, and receives a 120%-of-that-fee royalty 13 months later — growing at the rate escalator for 30 years. The first Circular Royalty payment (Q4 2029) represents approximately Rs 1.5 crore per month on Phase Initial alone, growing every year. Over 30 years, Phase Initial alone returns approximately Rs 2,800 crore ($335M) in cumulative Circular Royalty to NMC treasury at current FWDC assumptions.

| Circular Royalty | Contractual royalty paid by Carbotura's SPV to NMC. Equal to 120% of the corresponding TMC Fee payment, paid 13 months later. Escalates at +1 percentage point per year for the 30-year term. Designed to exceed the TMC Fee on a per-ton basis at steady state. |
| COA | Circular Offtake Agreement. The 30-year Build-Own-Operate agreement between NMC and Carbotura's SPV. |
| FWDC | Facility Waste Disposal Cost. The per-tonne cost NMC currently incurs to dispose of manufacturing feedstock — estimated at $15/ton (ESTIMATED). Used as the planning basis for avoided disposal modelling only. Does not determine TMC Fee. |
| Gross Cost Displacement | The annual avoided disposal cost — feedstock volume × FWDC — representing what NMC would have paid in disposal costs under State A (current system). Quantified separately from royalty cash flow. |
| Net Municipal Fiscal Position | Circular Royalty Received minus TMC Fee Paid. Positive from Month 13 of COD. Does not include Gross Cost Displacement, which is a separate fiscal benefit. |
| Pre-Royalty Period | Months 1–12 of the COA. TMC Fee is paid; Circular Royalty has not yet commenced. NMC net position is negative during this period. Royalty begins rolling in Month 13. |
| BOO | Build-Own-Operate. Carbotura's SPV finances, builds, owns, and operates the ACM facility. NMC bears zero capital expenditure. |
| SPV | Special Purpose Vehicle. The project company established by Carbotura to finance and operate the ACM facility under the BOO structure. |
| CCP | Classification Condition Precedent. Carbotura's requirement that the ACM facility receive manufacturing (not solid waste) classification from MPCB as a prerequisite to COA execution. |
| ACM | Advanced Circular Manufacturing. Carbotura's industrial process for reforming post-use materials into manufactured products through Microwave Catalytic Reforming (MCR). |
| MPCB | Maharashtra Pollution Control Board. Issues consent to establish and operate industrial facilities in Maharashtra. Must confirm manufacturing classification for ACM under the CCP. |
