Abstract—Approximately 1.3 billion tons of food waste, or one-third of the food produced globally, is generated annually, which is enough to feed 2 billion people. Food waste is generated throughout the supply chain, during the procurement of raw materials for products, manufacturing, sales, and consumption. Furthermore, food waste is one of the most significant environmental problems. Although reductions in carbon dioxide emissions are being made around the world and are attributed to the use of fossil fuels, food waste involves the loss of various resources that are necessary elements in the production process and the release of greenhouse gases that contribute to climate change. In this study, synthetic hydrotalcite (Mg
