Sustainable Food Waste Management and Tracking System Using Blockchain

Efficient supply chain management is a laborious task in any company, but in food industry, there is extra complexity and risk of compromising supply chain in food waste management, which may directly affect consumer safety and the shelf life of goods. One possible solution is to use blockchain technology to improve the integrity, security, and transparency of food supply chain. This study intends to present a blockchain-based transparent traceability food supply system that would follow the passage of boxed leftovers from restaurants through nongovernmental organizations and lastly to the underprivileged. Furthermore, the system employs a QR code and an NFC tag to acquire access to secure data pertaining to food packaging. This can help to reduce fraud, theft, and counterfeiting, as well as improve the efficiency of leftover food supply chain.
