Increasing the stream of recycled plastic necessitates an approach beyond the traditional recycling via melting and re-extrusion. Various chemical recycling processes have great potential to enhance recycling rates. In this Review, a summary of the various chemical recycling routes and assessment via life-cycle analysis is complemented by an extensive list of processes developed by companies active in chemical recycling. We show that each of the currently available processes is applicable for specific plastic waste streams. Thus, only a combination of different technologies can address the plastic waste problem. Research should focus on more realistic, more contaminated and mixed waste streams, while collection and sorting infrastructure will need to be improved, that is, by stricter regulation. This Review aims to inspire both science and innovation for the production of higher value and quality products from plastic recycling suitable for reuse or valorization to create the necessary economic and environmental push for a circular economy.
提高再生塑料的供应量需要采用超越传统熔融再挤出的方法。各种化学回收工艺具有提高回收利用率的巨大潜力。在这篇综述中，各种化学回收途径的总结和通过生命周期分析的评估，辅之以积极从事化学回收的公司所开发的大量工艺过程列表。我们表明，目前可用的每种工艺都适用于特定的塑料废物流。因此，只有结合不同的技术才能解决塑料废物问题。研究应侧重于更现实、更污染和更混合的废物流，同时需要改进收集和分类基础设施，即通过更严格的监管。这篇综述旨在为从塑料回收中生产更有价值和质量更高的产品提供科学和创新的灵感，这些产品适合再利用或增值，为循环经济创造必要的经济和环境推动力。
