Nigeria-first smart bins that pay recyclers in airtime/data. Our Device verifies PEP, Hedera records the proof onchain # GreenAfrica ## Hedera Certification drive.google.com ## Pitch Deck drive.google.com **Track:** DLT for Operations **Sub-track**: 4, Sustainability & Impact Tech GreenAfrica turns reverse vending machines deployed across African cities into digitally verifiable recycling stations, pairing real-world bottle recovery with instant, tokenized rewards backed by Hedera's low-cost, high-trust infrastructure. ## Vision & Impact GreenAfrica's vision is to unlock a circular economy where every PET bottle keeps residual value and local recyclers earn reliable income without friction. We couple rugged reverse vending machines with a Hedera-backed loyalty layer so municipalities, FMCGs, and telecoms can co-fund incentives while seeing tamper-proof performance data. - Reduce plastic leakage by rewarding deposit behavior exactly where waste is generated (bus parks, markets, campuses). - Provide micro-earnings denominated as Green Points that convert into airtime/data bundles, smoothing household cash flow. - Deliver audit-ready climate impact evidence so grants and ESG budgets translate into transparent, measurable outcomes. ## Monorepo Overview | Folder | Role in platform | Primary stack | Notable outputs | | ---------- | ------------------------------------------------------------------------------------------------- | ------------------------------------- | ---------------------------------------------------------------------- | | `contract` | Solidity smart contracts for RVM registry, deposits, referrals, and redemptions | Hardhat, Solidity 0.8 | GreenAfrica.sol bytecode, contract ABIs, deployment scripts | | `rvm_api` | Edge service that runs on the ve …
