Growing concern regarding non-biodegradable plastics and the impact of these materials on the environment has promoted interest in biodegradable plastics. The intensification of separate biowastes collection in most European countries has also contributed to the development of biodegradable plastics, and the subject of their end-of-life is becoming a key issue. To date, there has been relatively little research to evaluate the biodegradability of biodegradable plastics by anaerobic digestion (AD) compared to industrial and home composting. However, anaerobic digestion is a particularly promising strategy for treating biodegradable organic wastes in the context of circular waste management. This critical review aims to provide an in-depth update of anaerobic digestion of biodegradable plastics by providing a summary of the literature regarding process performance, parameters affecting biodegradability, the microorganisms involved, and some of the strategies (e.g., pretreatment, additives, and inoculum acclimation) used to enhance the degradation rate of biodegradable plastics. In addition, a critical section is dedicated to suggestions and recommendations for the development of biodegradable plastics sector and their treatment in anaerobic digestion.
对不可生物降解塑料及其对环境影响的日益关注，激发了人们对生物可降解塑料的兴趣。大多数欧洲国家加强了生物垃圾的分类收集，这也推动了生物可降解塑料的发展，其生命周期结束的问题正成为一个关键问题。迄今为止，与工业堆肥和家庭堆肥相比，通过厌氧消化（AD）评估生物可降解塑料生物降解性的研究相对较少。然而，在循环废物管理的背景下，厌氧消化是处理可生物降解有机废物的一种特别有前景的策略。这篇综述旨在通过总结有关工艺性能、影响生物降解性的参数、涉及的微生物以及一些用于提高生物可降解塑料降解率的策略（如预处理、添加剂和接种物驯化）的文献，对生物可降解塑料的厌氧消化进行深入更新。此外，一个关键部分专门针对生物可降解塑料行业的发展及其厌氧消化处理提出建议。
