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.
由于其优越的物理化学性质，塑料的实际使用量迅速增加。尽管塑料具有优异的物理化学性质，但其较短的使用寿命不可避免地导致了大量塑料垃圾的产生。因此，在废物管理中，对塑料垃圾的潜在危害进行战略缓解被视为至关重要。特别是，考虑到包装塑料垃圾的大量产生，建立一个可靠的回收平台非常重要。为了确定减少塑料垃圾潜在危害的战略手段，还必须实施对其进行合法管理的立法。本综述强调了聚乙烯、聚丙烯、聚对苯二甲酸乙二酯、聚苯乙烯和聚氯乙烯的机械和化学回收方法，并讨论了将塑料垃圾转化为增值化学产品的技术平台。本研究还提供了一种可持续增值的观点，作为循环资源的一种实际替代方案。
