Chemical Recycling of Waste Plastics:Methods,Current Status and Prospects
Benefiting from low-cost,low density,strong durability,and adjustable performance,plastic products were closely related to people's clothing,food,housing,and transportation.However,due to the poor degradation performance of plastics and the lack of a complete recycling mechanism,a series of ecological problems had also emerged.With the aggravation of the energy crisis and the low economic efficiency of materials,it was necessary to explore ways to recycle waste plastics to achieve sustainable development.Traditional physical recycling methods had problems,such as,limited applicability and reduced polymer performance,while chemical recycling could theoretically decompose and reassemble plastics at the molecular level to form monomers or other high value-added products.This article was based on the chemical methods of plastic recycling,the current industry status and research progress of chemical recycling were summarized,the corresponding recycling mechanisms and constraints on recycling were analyzed,thus a certain reference could be provided for the development of chemical recycling and reusing technologies for plastics.Through the development of novel catalytic processes and the design of efficient reaction systems,chemical recycling might be the key to driving the circular plastics economy.
