废弃通用塑料的环境危害分析及其资源再利用方法OA

With the continuous growth in the consumption of various general plastic products,increasingly serious plastic pollution problems were brought to the global environment.The hazards of waste general plastics to the environment were analyzed,and then the frontier resource recycling methods for waste general plastics,including primary recycling,mechanical recycling,chemical recycling and enzymatic recycling,were systematically reviewed,along with the principles,characteristics and application prospects corresponding to these recycling methods.The results showed that among these methods,chemical recycling and enzymatic recycling,through innovative catalyst design and mild reaction conditions,could efficiently convert waste general plastics into monomers,fuels,high-value chemicals and novel functional materials,and thus the mode transformation from"linear consumption"to"circular regeneration"could be realized.
