Plastics are a ubiquitous and growing presence in our lives, with chlorinated plastics, like polyvinyl chloride (PVC), playing a pivotal role due to their superior qualities. However, the disposal and recycling of these materials present significant challenges. The chlorine content can harm catalysts, corrode equipment, and create dangerous pollutants, making the management of chlorinated plastic waste a critical issue in recycling efforts. There is a pressing need for green, effective, and atom‐efficient methods to handle this waste responsibly. This review explores the potential for converting chlorinated plastic waste into valuable resources. We examine four key areas for upcycling and reusing PVC waste, including innovative separation techniques, leveraging the PVC molecular structure, and recycling the chlorine and carbon components inherent in PVC. By offering a thorough analysis of current recycling strategies and highlighting existing solutions, our review aims to inform and inspire further research in this crucial field, pushing towards more sustainable waste management practices.
