In contemporary times, global plastic waste production has doubled in comparison to two decades ago, with only 9% effectively recycled. The polymer industry is undergoing a transition to address the disparity between plastic production and end-of-life waste management. Chemical recycling offers a solution by converting plastic waste into its constituent building blocks, or monomers, which can be utilized in the production of new, high-quality plastics. This concise review provides an overview of conventional chemical recycling technologies employing heated reactors, before delving into ongoing efforts towards electrifying the chemical recycling process. A conceptual framework for a fully electrified value chain aimed at achieving plastics circularity is outlined and analyzed. Additionally, attention is given to the challenges posed by industry inertia towards adopting electrified technologies, as well as performance issues stemming from the intermittent nature of renewable energy sources and the availability of long-duration renewable electricity storage options.
在当代，全球塑料垃圾产量相较于二十年前已经翻了一番，仅有9%得到有效回收利用。聚合物行业正在经历转型，以解决塑料生产与报废后废物管理之间的差距。化学回收提供了一种解决方案，即将塑料垃圾转化为其组成原料，也就是单体，这些单体可用于生产新的高质量塑料。本简要综述首先概述了采用加热反应器的传统化学回收技术，然后深入探讨了使化学回收过程电气化的当前努力。概述并分析了旨在实现塑料循环利用的全电气化价值链的概念框架。此外，还关注了行业惯性对采用电气化技术带来的挑战，以及可再生能源间歇性本质和长期可再生电力存储选项可用性所引发的性能问题。
