摘要

摘要: 为促进再生铜行业健康可持续发展,以进口再生铜原料以及国内废铜为原料制备的再生铜为研究对象,采用ReCiPe 2016中间点和终点方法进行生命周期评价,并对生产过程中造成环境影响的主要因素进行分析。结果表明:与国内废铜再生相比,进口再生铜原料资源化生产的环境影响相对较小。各环境影响类别中,人类致癌毒性是进口再生铜原料资源化以及国内废铜再生过程中最为显著的环境影响。能源、运输和生产排放是进口再生铜原料资源化对人类健康的影响前3大贡献者,分别占比46.7%、37.4%和14.2%。国内废铜再生过程中,能源、生产排放和辅料对人类健康的影响贡献较高,分别占比37.9%、31.1%和27.1%。基于上述分析并结合我国实际,提出了减轻再生铜生产过程环境影响的建议。

Abstract: To promote the healthy and sustainable development of the recycled copper industry, the imported recycled copper raw materials as well as the recycled copper prepared from China’s domestic copper scrap as raw materials, were taken as the research objects, and the ReCiPe 2016 mid-point and end-point methods were used to carry out the life cycle assessment and analyze the main factors causing environmental impacts in the production process. The results show that the environmental impact of the imported recycled copper raw material resource production is relatively smaller compared with the domestic copper scrap recycling. Among the environmental impact categories, human carcinogenicity toxicity is the most significant environmental impact in the process of the imported recycled copper raw materials and domestic copper scrap recycling. Energy, transportation, and production emissions are the top three contributors to the human health impacts of imported recycled copper feedstock resourcing, accounting for 46.7%, 37.4%, and 14.2%, respectively. In the process of domestic copper scrap regeneration, energy, production emissions, and auxiliary materials contribute more to the impact on human health, accounting for 37.9%, 31.1%, and 27.1%, respectively. Based on the above analysis and combined with China’s actual situation, suggestions are put forward to mitigate the environmental impact of the recycled copper production process.
