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 (FW) can be converted into sustainable animal feed, reducing waste disposal and providing an alternative protein source for animals. The utilization of FW as animal feed presents a solution that not only tackles challenges pertaining to FW management and food security but also lessens the demand for the development of traditional feed, which is an endeavour 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 FW, as well as advanced treatment methods that can be used to recycle FW into high-quality animal feed and its limitations, as well as the benefits and drawbacks of using FW as animal feed. Finally, the review concludes that utilization of FW as animal feed can provide a sustainable solution for FW management, food security, preserving resources, reducing environmental impacts, and contributing to the circular bioeconomy.
人口增长和对健康食品的需求导致了食物垃圾产生量的增加，造成了严重的环境和经济影响。然而，食物垃圾（FW）可以转化为可持续的动物饲料，减少垃圾处理，并为动物提供替代蛋白质来源。将FW用作动物饲料提供了一种解决方案，不仅可以应对与FW管理和粮食安全相关的挑战，还可以减少对传统饲料开发的需求，而传统饲料开发本质上是一项资源和环境密集型的工作。此外，这种方法还可以通过创建一个减少自然资源使用并将环境污染降至最低的闭环系统，为循环经济做出贡献。因此，本综述讨论了FW的特征和类型，以及可用于将FW回收为高质量动物饲料的先进处理方法及其局限性，以及将FW用作动物饲料的利弊。最后，综述得出结论，将FW用作动物饲料可以为FW管理、粮食安全、资源保护、减少环境影响以及为循环生物经济做出贡献提供一个可持续的解决方案。
