摘　　要：以废弃手机为研究对象,采用生命周期评价方法分析了当前我国废弃手机回收处理系统的能耗和碳足迹.研究结果表明,废弃手机回收处理全生命周期能耗与碳足迹分别为-1069.86MJ和-60.38kg CO_2-eq.再生材料产出是废弃手机回收处理生命周期能耗和碳足迹最主要的贡献来源,其对能耗和碳足迹的贡献分别为88.3%和96.8%.敏感性分析显示,提高互联网在线回收平台的日回收量及拆解部件和元器件的再使用比例,可有效降低废弃手机回收处理系统的生命周期能耗和碳足迹.A life cycle assessment is carried out to estimate the energy use and carbon footprint of waste mobile phonetreatment system in China.The results showed that the energy use and GHG emissions of waste mobile phone treatmentare-1069.86MJ and-60.38kg CO2-eq.The recycled material is the main source of life cycle energy use and carbonfootprint,with the contribution proportion of88.3%and96.8%,respectively.A quantitative analysis is also conducted toassess the influence of website-based collection efficiency and the reuse rate of disassembled components.
