One of the major challenges in sustainable waste management in the agri-food industry following the "zero waste" model is the application of the circular economy strategy, including the development of innovative waste utilization techniques. The conversion of agri-food waste into carriers for the immobilization of enzymes is one such technique. Replacing chemical catalysts with immobilized enzymes (i.e., immobilized/heterogeneous biocatalysts) could help reduce the energy efficiency and environmental sustainability problems of existing chemically catalysed processes. On the other hand, the economics of the process strongly depend on the price of the immobilized enzyme. The conversion of agricultural and food wastes into low-cost enzyme carriers could lead to the development of immobilized enzymes with desirable operating characteristics and subsequently lower the price of immobilized enzymes for use in biocatalytic production. In this context, this review provides insight into the possibilities of reusing food industry wastes, namely, eggshells, coffee grounds, and brown onion skins, as carriers for lipase immobilization.
遵循“零浪费”模式，农业食品行业可持续废物管理面临的主要挑战之一是循环经济战略的应用，包括开发创新的废物利用技术。将农业食品废物转化为酶固定化载体就是这样一种技术。用固定化酶（即固定化/多相生物催化剂）替代化学催化剂有助于减少现有化学催化过程中的能源效率和环境可持续性问题。另一方面，该过程的经济性在很大程度上取决于固定化酶的价格。将农业和食品废物转化为低成本的酶载体可以开发出具有理想操作特性的固定化酶，从而降低用于生物催化生产的固定化酶的价格。在此背景下，本综述深入探讨了将食品工业废物，即蛋壳、咖啡渣和棕色洋葱皮，用作脂肪酶固定化载体的可能性。
