Food waste (FW) generated through various scenarios from farm to fork causes serious environmental problems when either incinerated or disposed inappropriately. The presence of significant amounts of carbohydrates, proteins, and lipids enable FW to serve as sustainable and renewable feedstock for the biorefineries. Implementation of multiple substrates and product biorefinery as a platform could pursue an immense potential of reducing costs for bio-based process and improving its commercial viability. The review focuses on conversion of surplus FW into range of value-added products including biosurfactants, biopolymers, diols, and bioenergy. The review includes in-depth description of various types of FW, their chemical and nutrient compositions, current valorization techniques and regulations. Further, it describes limitations of FW as feedstock for biorefineries. In the end, review discuss future scope to provide a clear path for sustainable and net-zero carbon biorefineries.
食物垃圾（FW）在从农场到餐桌的各种场景中产生，如果焚烧或处理不当，会造成严重的环境问题。FW 中含有大量的碳水化合物、蛋白质和脂质，使其成为生物精炼厂可持续和可再生的原料。实施多种底物和产品生物精炼厂作为一个平台，可以为基于生物的工艺降低成本并提高其商业可行性带来巨大的潜力。本综述重点介绍了将剩余的 FW 转化为一系列附加值产品，包括生物表面活性剂、生物聚合物、二醇和生物能源。本综述包括对各种类型的 FW 的详细描述，它们的化学和营养成分，以及当前的增值技术和法规。此外，它还描述了 FW 作为生物精炼厂原料的局限性。最后，综述讨论了未来的发展方向，为可持续和净零碳排放的生物精炼厂提供了明确的路径。
