What is it about?
Every year, huge amounts of food are wasted, sometimes because it spoils, sometimes because problems in the supply chain go unnoticed until it’s too late. This research explores how blockchain technology can help reduce that waste. By giving everyone in the food supply chain access to reliable, real-time information about where food comes from, how it’s stored, and when it expires, blockchain helps prevent spoilage, improve decision-making, and get more food to people instead of landfills. Using computer simulations of a five-step supply chain, the study shows that blockchain can significantly cut down on wasted food and lower costs, all while making the system more transparent and trustworthy for consumers.

Why is it important?
our work stands out by using discrete event simulation to quantify how blockchain reduces food waste, cuts costs, and improves efficiency in a realistic five-tier supply chain. Unlike most studies that rely on case studies or conceptual models, our approach offers actionable, data-driven evidence of blockchain’s real-world impact. This is especially timely as governments and businesses urgently seek scalable solutions to meet sustainability goals and tackle the global food waste crisis.
Perspectives
Food waste is not just a logistical issue; it’s a moral one, especially while millions go hungry. By using simulation to cut through the hype around blockchain, I wanted to offer evidence-based insight into how this technology can genuinely reduce waste, save costs, and rebuild trust in our food systems.
