摘要
Abstract
This study established a carbon footprint calculation method and an environmental benefit assessment model for the disassembly and treatment of waste televisions,based on the Life Cycle Assessment(LCA)methodology.Through field surveys,energy consumption and material data from typical treatment enterprises were collected,and the ReCiPe 2016 model was used to quantify various environmental impacts of the dismantling,including global warming,resource consumption,and ecotoxicity.The results indicated that the waste television dismantling and recycling process demonstrated net environmental benefits in most impact categories.Significant contributions were observed in midpoint impact categories such as fossil resource scarcity(−26 494.23 kg oil eq),freshwater ecotoxicity(-2.21×104 kg 1,4-DCB eq),and greenhouse gas reduction(−956.53 kg CO2 eq).In endpoint impact categories,notable environmental benefits were also achieved in human health damage(−1.59×104 Daly),ecosystem damage(−2.35×104 species year),and resource depletion(−4.22×104 $).Carbon footprint analysis revealed that the carbon footprint per television unit ranges from 0.231 to 0.247 kg CO2 eq·u−1,with electricity consumption being the primary emission source.Sensitivity analysis highlighted the significant influence of dismantling electricity consumption on the carbon footprint.Finally,emission reduction recommendations were proposed in areas:Upgrading equipment,and improving energy management,providing theoretical and practical guidance for low-carbon treatment of electronic waste.关键词
