Waste animal fats and proteins (WAFP) are rich in various animal by-products from food industries. On one hand, increasing production of huge amounts of WAFP brings a great challenge to their appropriate disposal, and raises severe risks to environment and life health. On the other hand, the high fat and protein contents in these animal wastes are valuable resources which can be reutilized in an eco-friendly and renewable way. Sustainable enzymatic technologies are promising methods for WAFP management. This review discussed the application of various enzymes in the conversion of WSFP to value-added biodiesel and bioactivate hydrolysates. New biotechnologies to discover novel enzymes with robust properties were proposed as well. This paper also presented the bio-utilization strategy of animal fat and protein wastes as alternative nutrient media for microorganism growth activities to yield important industrial enzymes cost-effectively.
废弃动物脂肪和蛋白质（WAFP）是食品工业中各种动物副产品的丰富来源。一方面，大量 WAFP 的产量增加给它们的适当处理带来了巨大挑战，并对环境和生命健康造成了严重风险。另一方面，这些动物废物中的高脂肪和高蛋白含量是有价值的资源，可以以环保和可再生的方式重新利用。可持续的酶技术是 WAFP 管理的有前途的方法。本综述讨论了各种酶在将 WSFP 转化为增值生物柴油和生物激活水解物方面的应用。还提出了新的生物技术来发现具有稳健特性的新型酶。本文还提出了动物脂肪和蛋白质废物的生物利用策略，作为替代营养培养基，用于微生物生长活动，以经济有效地产生重要的工业酶。
