Bioplastics are becoming more and more widespread as substitutes for petroleum-derived plastics due to their biodegradability. Bioplastics degradation under different environments has been described and reported to depend mainly on bioplastics' compositions and the environmental conditions. Incomplete degradation during waste management processes and leakage of bioplastics into the environment are becoming major concerns that need to be further investigated. In this context, the present paper aimed to review recent literature dealing with biodegradation of bioplastics under industrial (e.g. anaerobic digestion and composting) and natural (e.g. soil and water) environments, and to link it to the potential bioplastics' leakage into the environment. Reviewed data were used to estimate the potential role of waste management processes in decreasing the potential leakage of bioplastics. Depending on bioplastics' type and processing conditions, waste management can effectively reduce bioplastics' potential leakage, decreasing the concentration of these materials that can reach the natural environments.
由于生物塑料具有生物降解性，因此它们越来越多地被用作石油衍生塑料的替代品。已经描述并报道了生物塑料在不同环境下的降解情况，主要取决于生物塑料的组成和环境条件。在废物管理过程中不完全降解以及生物塑料泄漏到环境中，这些问题正成为需要进一步调查的主要关注点。在这种情况下，本文旨在综述近期有关生物塑料在工业（例如厌氧消化和堆肥）和自然（例如土壤和水）环境中生物降解的文献，并将其与生物塑料潜在泄漏到环境中的情况联系起来。所审查的数据用于估算废物管理过程在减少生物塑料潜在泄漏方面的作用。根据生物塑料的类型和加工条件，废物管理可以有效地减少生物塑料的潜在泄漏，降低可能进入自然环境的这些材料的浓度。
