Plastics are everywhere in our modern way of living, and their production keeps increasing every year, causing major environmental concerns. Nowadays, the end-of-life management involves accumulation in landfills, incineration, and recycling to a lower extent. This ecological threat to the environment is inspiring alternative bio-based solutions for plastic waste treatment and recycling toward a circular economy. Over the past decade, considerable efforts have been made to degrade commodity plastics using biocatalytic approaches. Here, we provide a comprehensive review on the recent advances in enzyme-based biocatalysis and in the design of related biocatalytic processes to recycle or upcycle commodity plastics, including polyesters, polyamides, polyurethanes, and polyolefins. We also discuss scope and limitations, challenges, and opportunities of this field of research. An important message from this review is that polymer-assimilating enzymes are very likely part of the solution to reaching a circular plastic economy.

酶的塑料降解能力

塑料在我们现代生活方式中无处不在，其产量每年都在增加，引起了重大的环境问题。如今，报废管理涉及垃圾填埋场的积累、焚烧和回收，程度较低。这种对环境的生态威胁正在激发塑料废物处理和回收利用的替代生物基解决方案，以实现循环经济。在过去的十年中，人们做出了相当大的努力来使用生物催化方法来降解商品塑料。在这里，我们全面回顾了基于酶的生物催化以及相关生物催化工艺设计的最新进展，以回收或升级再循环商品塑料，包括聚酯、聚酰胺、聚氨酯和聚烯烃。我们还讨论范围和限制、挑战、和这个研究领域的机会。这篇综述的一个重要信息是，聚合物同化酶很可能是实现循环塑料经济的解决方案的一部分。
