A life cycle assessment is carried out to estimate the energy use and carbon footprint of waste mobile phone treatment system in China. The results showed that the energy use and GHG emissions of waste mobile phone treatment are -1069.86MJ and -60.38kg CO2-eq. The recycled material is the main source of life cycle energy use and carbon footprint, with the contribution proportion of 88.3% and 96.8%, respectively. A quantitative analysis is also conducted to assess the influence of website-based collection efficiency and the reuse rate of disassembled components.
