Taking waste computer as an example,a method of waste electrical and electronic equipment(WEEE)recycle and reuse developed by the laboratory was studied.Four key units including cathode ray tube(CRT)recycle,circuit board disassembly,print circuit board(PCB)recycle and parts reusability test were analyzed carefully.The largest parts reuse and materials recycling rate by environmental friendly materials recycle and PCB undamaged auto-disassembly process were realized,with the largest recycle gains.
