The strength, flexibility and light weight of traditional oil-derived plastics make them ideal materials for a large number of applications, including packaging, medical devices, building, transportation, etc. However, the majority of produced plastics are single-use plastics, which, coupled with a throw-away culture, leads to the accumulation of plastic waste and pollution, as well as the loss of a valuable resource. In this review we discuss the advances and possibilities in the biotransformation and biodegradation of oil-based plastics. We review bio-based and biodegradable polymers and highlight the importance of end-of-life management of biodegradables. Finally, we discuss the role of a circular economy in reducing plastic waste pollution.
传统石油基塑料具有强度高、柔韧性好、重量轻等特点，是许多应用领域（包括包装、医疗器械、建筑、运输等）的理想材料。然而，目前生产的大部分塑料都是一次性塑料，再加上一次性文化，导致塑料废物和污染的积累，以及宝贵资源的浪费。在这篇综述中，我们讨论了石油基塑料的生物转化和生物降解方面的进展和可能性。我们回顾了生物基和可生物降解聚合物，并强调了可生物降解材料的生命周期管理的重要性。最后，我们讨论了循环经济在减少塑料废物污染方面的作用。
