Polyvinyl chloride (PVC) is a polymer comprised of more than 50% chlorine that offers unmatched versatility at low expense. PVC is irreplaceable in several applications, such as construction materials, medical applications, and cables. This versatility and tunable properties come at the cost of complex formulations for the product and challenging end-of-life (EoL) options for PVC waste. Pure collected and sorted PVC is already recycled successfully to some extent, yet, when PVC ends up in a mixed plastic waste stream, it can be detrimental to the recycling process. PVC waste and its effects at various concentrations remain a focal point for both scholars and policymakers. In this review, the narrative begins at the naissance of PVC and continues to investigate the EoL valorization options when the products are inevitably discarded. Strategies for PVC waste recycling and the technical and legal challenges regarding each method are discussed, focusing on the European recycling market. An effective solution to handle EoL PVC requires a combination of policies and schemes for proper collection and sorting of specific waste streams and considering all available technologies to select the right tools. This review can support appropriate policies and the selection of suitable methods of recycling PVC waste.
聚氯乙烯（PVC）是一种聚合物，其氯含量超过50%，能以低成本提供无与伦比的通用性。PVC在多种应用中不可替代，如建筑材料、医疗应用和电缆。这种通用性和可调节特性是以产品复杂配方以及PVC废料具有挑战性的报废处理选项为代价的。纯净收集和分类的PVC已在一定程度上成功回收利用，然而，当PVC最终进入混合塑料废物流时，可能会对回收过程产生不利影响。不同浓度的PVC废料及其影响仍然是学者和政策制定者关注的焦点。在本综述中，叙述从PVC的诞生开始，并继续探讨产品不可避免地被丢弃时的报废增值选项。讨论了PVC废料回收策略以及每种方法面临的技术和法律挑战，重点关注欧洲回收市场。处理PVC报废产品的有效解决方案需要一系列政策和计划相结合，以便对特定废物流进行适当收集和分类，并考虑所有可用技术来选择合适的工具。本综述可为制定适当政策以及选择合适的PVC废料回收方法提供支持。
