Waste equals food

"Waste equals food" is a concept from sustainable design suggesting that what we typically see as waste can be repurposed as a valuable resource for other processes. Instead of discarding waste, it can be transformed or reused, much like how natural ecosystems recycle nutrients. For example, food scraps can become compost for plants, and industrial byproducts can serve as raw materials for new products. This approach minimizes environmental impact, reduces resource consumption, and promotes a circular economy where waste is integrated back into the system as input, supporting more sustainable and efficient practices.
