Abstract

Polyester waste in the environment threatens public health and environmental ecosystems. Chemical recycling of polyester waste offers a dual solution to ensure resource sustainability and ecological restoration. This minireview highlights the traditional recycling methods and novel recycling strategies of polyester plastics. The conventional strategy includes pyrolysis, carbonation, and solvolysis of polyesters for degradation and recycling. Furthermore, the review delves into exploring emerging technologies including hydrogenolysis, electrocatalysis, photothermal, photoreforming, and enzymatic for upcycling polyesters. It emphasizes the selectivity of products during the polyester conversion process and elucidates conversion pathways. More importantly, the separation and purification of the products, the life cycle assessment, and the economic analysis of the overall recycling process are essential for evaluating the environmental and economic viability of chemical recycling of waste polyester plastics. Finally, the review offers perspective into the future challenges and developments of chemical recycling in the polyester economy.

聚酯废料的循环经济和化学转化。

环境中的聚酯废料威胁着公众健康和环境生态系统。聚酯废料的化学回收为确保资源可持续性和生态恢复提供了双重解决方案。本小节重点介绍聚酯塑料的传统回收方法和新型回收策略。传统策略包括热解、碳化和溶解聚酯以实现降解和回收。此外，该综述还深入探讨了用于聚酯升级再循环的新兴技术，包括氢解、电催化、光热、光成形和酶解技术。报告强调了聚酯转化过程中产品的选择性，并阐明了转化途径。更重要的是，产品的分离和提纯、生命周期评估以及整个回收过程的经济分析对于评估废旧聚酯塑料化学回收的环境和经济可行性至关重要。最后，本综述对聚酯经济中化学回收的未来挑战和发展提出了展望。
