摘要
自20世纪50年代塑料大规模生产以来,塑料及其产品得到广泛应用,随之带来的是如何进行塑料废弃物的处理问题,这是需全球共同面对的重大挑战。文中综述了塑料废弃物产生和回收的现状,对未来有望的可能解决途径进行了探讨,包括多相相容剂增容塑料废弃物实现高效回收及高值化再利用、开发能量使用较低的化学裂解回收方法以及开发推广生物可降解塑料,并分析了3种方法的各自优势与互补,指出通过多相相容剂增容对废塑料回收高值化再利用是极具前景,且技术可行的一种便捷方法。
Since the large-scale production of plastics in the 1950s,along with the widespread use of plastics and their products,the issue of how to deal with plastic waste has been brought about and is a major challenge facing the whole world.This article reviewed the current status of generation and recycling of plastic waste,and discussed three possible solutions in the future,including multi-phase compatibilizers compatibilizing plastic waste to achieve the high-efficiency recycling and value-added utilization,development of pyrolysis recycling methods with low energy consumption,and the development and promotion of biodegradable plastics.Meanwhile,the respective advantages and complementarities of various methods were analyzed.It’s pointed out that the higher-value recycling of plastic waste through multi-phase compatibilizers is a promising,technically feasible and convenient method.
