SGC is a blockchain-powered Blockchain-MRV protocol that transforms organic waste diversion in Nigeria into internationally-certified carbon credits — giving young waste entrepreneurs direct access to global climate finance for the first time.
Nigeria generates over 32 million tonnes of solid waste annually. Over 60% is biodegradable organic material. When abandoned in unmanaged dumpsites — which is almost all of it — it decomposes anaerobically, releasing methane at a rate 84 times more damaging than CO₂ over 20 years.
The Voluntary Carbon Market pays for every tonne of methane that is provably abated. A young Nigerian entrepreneur who diverts organic waste from a dumpsite is entitled to carbon revenue. But they cannot access it — blocked by a verification process that costs $50,000 upfront and takes 18–24 months.
SGC eliminates that barrier entirely.
The SGC mobile app paired with an IoT-integrated scale captures weight, GPS coordinates, photos, and waste classification at the collection site. Every data point is cryptographically signed with the operator's private key — tamper-proof at the moment of capture.
IOT + MOBILE + CRYPTOGRAPHYThe signed payload is transmitted to the SGC Oracle, which runs the IPCC-approved First Order Decay (FOD) equation using Nigerian-specific parameters. The Oracle computes the Methane Emission Reduction (MER) in tCO₂e in seconds. No human auditor. No 18-month wait.
IPCC FOD · AUTOMATED MRVA smart contract receives the verified MER value and automatically mints SGC tokens — 1 SGC = 1 tCO₂e avoided. The record is permanently written on-chain. The operator receives 100% of their earned tokens. The platform receives a 10% add-on mint for sustainability.
SOLANA BLOCKCHAIN · SMART CONTRACTEvery figure below is derived from an IPCC-validated First Order Decay model using Nigerian MSW parameters, peer-reviewed literature, and live VCM price data — not projections built on hope.
For every tonne of organic waste diverted, the IPCC FOD model computes the baseline methane emission. Multiplied by GWP₂₀ = 84, this gives the number of SGC tokens minted. Distribution is enforced automatically by smart contract:
The 10% platform add-on is minted in addition to the operator's full 100% — it does not reduce their earnings. The operator's incentive is always maximised.
The SGC Feasibility Simulator puts the full financial model in your hands. It runs the same IPCC First Order Decay equations and Nigerian-calibrated parameters used in this research — and recalculates every output in real time as you move the sliders.
Nigeria's Carbon Market Activation Policy (NCMAP) was signed in March 2025. The national carbon registry has been operational since 2024 under the Africa Carbon Market Initiative. Methane reduction from waste is explicitly listed as a priority credit type. The regulatory infrastructure that SGC needs has just been built.
The global VCM methane capture segment is growing at 34.5% CAGR — the fastest of any project category. Africa issued ~75 million credits valued at $15 billion in 2024, a 200%+ annual increase. The window for first-mover advantage in Nigerian methane abatement credits is now.
NCMAP 2025 establishes national carbon registry, project eligibility rules, and incentives for private credit generation. Methane reduction explicitly named as priority.
Nigeria signed the Global Methane Pledge committing to 30% CH₄ reduction by 2030. SGC's infrastructure directly enables Nigeria's NDC reporting obligations.
SGC's credit calculation methodology is grounded in IPCC 2006 Vol.5 and Gold Standard DOWP v1.1 — the two most widely accepted international standards for waste methane credits.
The Africa Carbon Markets Initiative estimates Nigeria can generate 30 million carbon credits annually by 2030, worth over $500M/yr. SGC is positioned as the infrastructure for the waste sector of this.
SGC is raising its seed round to complete the platform, onboard the first 50 PSP operators in Southeast Nigeria, and register on the national carbon registry. Join us at the beginning.
