New approaches are needed to both reduce and reuse plastic waste. In this context, poly(vinyl chloride) (PVC) is an appealing target as it is the least recycled high-production-volume polymer due to its facile release of plasticizers and corrosive HCl gas. Herein, these limitations become advantageous in a paired-electrolysis reaction in which HCl is intentionally generated from PVC to chlorinate arenes in an air- and moisture-tolerant process that is mediated by the plasticizer. The reaction proceeds efficiently with other plastic waste present and a commercial plasticized PVC product (laboratory tubing) can be used directly. A simplified life-cycle assessment reveals that using PVC waste as the chlorine source in the paired-electrolysis reaction has a lower global warming potential than HCl. Overall, this method should inspire other strategies for repurposing waste PVC and related polymers using electrosynthetic reactions, including those that take advantage of existing polymer additives.

需要新的方法来减少和再利用塑料废物。在这种情况下，聚氯乙烯 (PVC) 是一个有吸引力的目标，因为它容易释放增塑剂和腐蚀性 HCl 气体，因此是回收最少的高产量聚合物。在此，这些限制在配对电解反应中变得有利，在该反应中，在由增塑剂介导的耐空气和耐湿过程中，有意从 PVC 中产生 HCl 以氯化芳烃。该反应在存在其他塑料废物的情况下有效进行，并且可以直接使用商业塑化 PVC 产品（实验室管材）。简化的生命周期评估表明，使用 PVC 废物作为配对电解反应中的氯源具有比 HCl 更低的全球变暖潜能值。全面的，
