Abstract: Taking waste print-copy multifunction machine for example, the environmental impacts of recycling and disposal of waste printer was evaluated with life cycle assessment (LCA) approach, and according to the assessment results for the future recycle and disposal of waste printer, countermeasures of supervision and management were put forward. The results showed that the recycling and disposal of waste printer had environmental benefits, and life-cycle environmental impacts were mainly concentrated in decreasing inorganic damage to people, climate change, ecological toxicity and fossil energy, while impacts in acidification, eutrophication, and mineral resources had little change. The transportation and power consumption were the main steps to cause negative environmental impacts, and the recycling of metal and plastic in the disposal process generated positive environmental benefits. Sensitivity analysis results showed that plastic was the most sensitive for life cycle environmental impacts of waste printer, followed by power consumption, again was the metal. For waste printer recycling disposal in the future, it need to carry out standardized recycling and dismantling, lower power consumption, and promote the research of plastic and metal recycling technology, to further improve the environmental benefits brought by recycling and disposal of waste printer.
