摘要

由于塑料优异的物理化学性能，其实际用途迅速增加。尽管塑料具有优异的物理化学性能，但塑料的短寿命不可避免地导致了大量塑料废物的产生。因此，战略性地减少塑料废物的潜在危险已被视为废物管理的重要内容。特别是，建立一个可靠的包装塑料废物回收平台是非常重要的，因为它的大量产生。为了确定减少塑料废物潜在危害的战略手段，还必须实施立法，对其进行合法管理。本文着重介绍了聚乙烯、聚丙烯、聚对苯二甲酸乙二醇酯、聚苯乙烯和聚氯乙烯的机械和化学回收方法，并探讨了塑料废物转化为增值化工产品的技术平台。本研究还提供了可持续增值作为循环资源的实际替代方案的观点。

Current methods for plastic waste recycling: Challenges and opportunities

The practical use of plastics has rapidly increased owing to their superior physicochemical properties. Despite their excellent physicochemical properties, the short lifespan of plastics has inevitably led to a substantial generation of plastic waste. As such, strategic mitigation of the hazardous potential of plastic waste has been regarded as significant in waste management. In particular, establishing a reliable recycling platform for packaging plastic waste is of great importance considering its massive generation. To identify a strategic means of abating the hazardous potential of plastic waste, legislative enactment for their legal management must also be implemented. This review emphasizes the mechanical and chemical recycling methods for polyethylene, polypropylene, polyethylene terephthalate, polystyrene, and polyvinyl chloride, and discusses a technical platform for converting plastic waste into value-added chemical products. This study also offers a perspective on sustainable valorization as a practical alternative to circular resources.
