退役晶硅光伏组件回收与资源化利用研究进展OA

Green recycling and resource utilization are the key to breaking the deadlock of the coming wave of decommissioned photovoltaic(PV)modules.This paper systematically reviews the manage-ment policies,mainstream technologies and full-life-cycle environmental impacts of decommissioned PV modules.Currently,the recycling and resource utilization of decommissioned PV modules still face multiple challenges in the coordination of technology,economy and policy:mainstream technolo-gies such as pyrolysis and hydrometallurgy still need breakthroughs in efficient removal of ethylene-vinyl acetate copolymer(EVA)encapsulation film and low-carbon recovery of valuable metals.Major economies such as China,the European Union and the United States have initially established an ex-tended producer responsibility framework.Under this framework,resource utilization pathways are showing a diversified trend,expanding from traditional material recycling to high value-added direc-tions such as conversion into building materials and photocatalysts,showing significant potential.However,technical implementation and policy coordination still need to be strengthened.Life cycle assessment confirms that recycling can effectively reduce full-cycle carbon emissions and environmen-tal toxicity,but secondary pollution control in the process needs urgent optimization.Finally,this pa-per prospects the future of resource recovery,policy management and industrial application of de-commissioned PV modules.
