The growing population and healthy food demands have led to a rise in food waste generation, causing severe environmental and economic impacts. However, food waste can be converted into sustainable animal feed, reducing waste disposal and providing an alternative protein source for animals. The utilization of food waste as animal feed presents a solution that not only tackles challenges pertaining to food waste management and food security but also lessens the demand for the development of traditional feed, which is an endeavor that is both resource and environmentally intensive in nature. Moreover, this approach can also contribute to the circular economy by creating a closed-loop system that reduces the use of natural resources and minimizes environmental pollution. Therefore, this review discusses the characteristics and types of food waste, as well as advanced treatment methods that can be used to recycle food waste into high-quality animal feed and its limitations, as well as the benefits and drawbacks of using food waste as animal feed. Finally, the review concludes that the utilization of food waste as animal feed can provide a sustainable solution for food waste management, food security, preserving resources, reducing environmental impacts, and contributing to the circular economy.
