Due to the lack of efficient end-of-life management, the mass production of plastics has resulted in serious environmental problems. Sustainable biological approaches using enzymes to degrade and recycle plastic waste are emerging as a complement to conventional methods to promote a circular economy of plastics. Only a fraction of the plastic waste generated is currently suitable for biocatalytic deconstruction and the development of economically and environmentally competitive processes is still pending. Inconsistent claims about new plastic-degrading enzymes reveal a need for robust and standardized analysis methods to ensure reproducible results and a realistic evaluation of their potential. This paper critically reviews enzymatic synthetic polymer degradation and its recycling challenges.
由于缺乏有效的寿命终结管理，塑料的大规模生产已导致严重的环境问题。利用酶降解和回收塑料废物的可持续生物方法正在兴起，作为传统方法的补充，以促进塑料的循环经济。目前，所产生的塑料废物中只有一小部分适合进行生物催化解构，经济和环境竞争力强的工艺仍有待开发。关于新型塑料降解酶的说法不一，这表明需要强大且标准化的分析方法，以确保结果的可重复性，并对其潜力进行现实评估。本文批判性地综述了酶促合成聚合物降解及其回收面临的挑战。
