摘要

当代，全球塑料废物产量与20年前相比翻了一番，其中只有9%得到有效回收。聚合物行业正在经历转型，以解决塑料生产和报废废物管理之间的差距。化学回收提供了一种解决方案，将塑料废物转化为其组成单元或单体，可用于生产新的高质量塑料。在深入研究电气化化学回收过程之前，本文简要介绍了采用加热反应器的传统化学回收技术。概述并分析了旨在实现塑料循环的全电气化价值链的概念框架。此外，还关注了采用电气化技术的行业惯性所带来的挑战，以及可再生能源的间歇性和长期可再生电力存储选择的可用性所带来的性能问题。

An electricity-powered future for mixed plastic waste chemical recycling

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.
