摘要：

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. © 2021, Editorial Board of Polymer Materials Science & Engineering.
