Recent advances in polyvinyl chloride (PVC) recycling

Abstract Polyvinyl chloride (PVC) recycling is crucial for mitigating the environmental impact of PVC wastes, which take decades to decompose in landfills. This review examines the current state of PVC recycling processes, focusing on challenges and future research opportunities. It explores the types and sources of PVC wastes, including post‐consumer, industrial, and construction wastes. Conventional recycling methods such as mechanical, thermal, and chemical recycling are discussed, highlighting their advantages, limitations, and successful applications. Furthermore, recent advances in PVC recycling, including biological, plasma‐assisted, and solvent‐based recycling, are explored, considering their potential benefits and challenges. The review emphasizes the European context of PVC recycling, as the region has implemented regulatory initiatives and collaborations. It points out the Circular Economy Action Plan and directives targeting PVC waste management, which have promoted recycling and established a supportive framework. Challenges of current PVC recycling methods and technologies, such as low yield and high energy consumption, are identified. The review calls for the development of efficient and cost‐effective recycling technologies, along with improvements in recycling infrastructure and consumer awareness. Assessing the environmental and economic impacts, PVC recycling significantly reduces greenhouse gas emissions and conserves resources compared to virgin PVC production. The economic benefits include job creation and reduced raw material costs.
