Current progress on plastic/microplastic degradation: Fact influences and mechanism
AI summary Read the abstract
This review examined current physicochemical and biological methods for degrading plastics and microplastics, including mechanical, UV, thermal, and microbial approaches. Researchers found that while multiple degradation pathways exist, their efficiency varies widely depending on polymer type and environmental conditions. The study highlights the need for more effective and scalable degradation technologies to address growing plastic pollution.
Plastic pollution, particularly non-degradable residual plastic films and microplastics (MPs), is a serious environmental problem that continues to worsen each year. Numerous studies have characterized the degradation of plastic fragments; however, there is known a lack of about the state of current physicochemical biodegradation methods used for plastics treatment and their degradation efficiency. Therefore, this review explores the effects of different physicochemical factors on plastics/MPs degradation, including mechanical comminution, ultraviolet radiation, high temperature, and pH value. Further, this review discusses different mechanisms of physicochemical degradation and summarizes the degradation efficiency of these factors under various conditions. Additionally, the important role of enzymes in the biodegradation mechanism of plastics/MPs is also discussed. Collectively, the topics discussed in this review provide a solid basis for future research on plastics/MPs degradation methods and their effects.
