Plastic wastes continuously accumulate, causing critical environmental issues. It is urgent to develop efficient strategies to convert them to valuable products. Very recently, two novel approaches for plastic recycling were reported by Huber et al. (Science, 2023, 381, 660‐666) and Liu et al. (Science, 2023, 381, 666‐671) , where polyethylene (PE) and polypropylene (PP) plastics were converted into potentially valuable products, such as alcohols, aldehydes, surfactants, and detergents. The two processes achieved complete degradation, high selectivity of target products, as well as high values of products, showing economic feasibility for industrial scale‐up. These breakthroughs for plastic recycling are highlighted in this article.

聚烯烃塑料废物完全降解为高价值产品

塑料废物不断积累，造成严重的环境问题。迫切需要制定有效的策略将其转化为有价值的产品。最近，Huber 等人报道了两种塑料回收的新方法。 （《科学》，2023, 381, 660-666）和 Liu 等人。 (Science, 2023, 381, 666-671)，其中聚乙烯 (PE) 和聚丙烯 (PP) 塑料被转化为具有潜在价值的产品，例如醇、醛、表面活性剂和洗涤剂。两种工艺实现了降解完全、目标产物选择性高、产品价值高，显示出工业放大的经济可行性。本文重点介绍了塑料回收方面的这些突破。
