Abstract
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.
