RePlate Campus - Food Waste Reduction Platform
RePlate Campus is a comprehensive web3-enabled platform designed to reduce food waste on university campuses by connecting students with discounted surplus food items from campus canteens. The platform features blockchain-based authentication, real-time food listings, secure claim code system, and smart contract rewards on the Celo blockchain.
The mission of RePlate Campus is to create a sustainable, tech-driven ecosystem that minimizes food waste across university campuses. By leveraging Web3 technology, blockchain transparency, and smart automation, the platform bridges the gap between canteens with surplus meals and students seeking affordable food options.
RePlate Campus aims to:
Reduce campus food waste through real-time redistribution of surplus meals.
Empower students and canteen staff with transparent and rewarding participation in sustainability.
Promote responsible consumption by encouraging students to claim discounted meals rather than letting food go to waste.
Foster collaboration among campuses, canteens, and NGOs to ensure excess food is donated efficiently.
Incentivize eco-conscious behavior using blockchain-based rewards and recognition (cUSD tokens & NFTs).
Ultimately, RePlate Campus envisions a zero-food-waste campus culture, where technology, community, and sustainability come together to make a measurable environmental and social impact.
Excess food waste in university canteens due to unsold or surplus meals.
Lack of coordination between students and canteens for redistributing leftover food efficiently.

Manual and inefficient tracking of food donations and waste management processes.
Absence of incentive systems to motivate students and canteen staff to participate in waste reduction.
Low transparency and trust in donation and reward systems without verifiable proof of transactions.
Difficulty verifying meal claims securely, leading to potential misuse or unclaimed meals.
