Abstract

The Cover Feature shows the chemical recycling of polyesters with a universally applicable zinc bisguanidine catalyst that is already highly active in the polymerization of lactide and ϵ-caprolactone. Replacing fossil-based plastics with recyclable bioplastics can pave the way towards a circular economy. Adapting the reaction conditions and varying the nucleophiles enables the production of value-added materials. These can act as green solvents or as starting materials for re-polymerization. Our catalyst enables selective degradation of PLA, allowing step-by-step recycling of plastic mixtures, and is an outstanding candidate for the implementation of a circular plastics economy. Further information can be found in the Research Article by S. Herres-Pawlis and co-workers. Cover design: T. Becker.

封面专题：开环和闭环回收：用于聚酯解聚的高活性双胍锌聚合催化剂（ChemSusChem 18/2024）

封面特写展示了利用一种普遍适用的双胍锌催化剂对聚酯进行化学回收的过程，这种催化剂在聚合内酯和ϵ-己内酯方面已经具有很高的活性。用可回收的生物塑料取代化石基塑料可以为实现循环经济铺平道路。调整反应条件和改变亲核物可以生产出增值材料。这些材料可用作绿色溶剂或再聚合的起始材料。我们的催化剂可以选择性地降解聚乳酸，从而逐步实现塑料混合物的循环利用，是实施循环塑料经济的理想选择。更多信息，请参阅 S. Herres-Pawlis 及其合作者的研究文章。封面设计：T. Becker。
