| Abstract: | Featuring huge amount,high potential economic value and great impact on environment,the reutilization of waste Printed Wiring Boards(PWBs) is of magnificent recovery value and environmental protection advantages.Physical treatments show great potential and advantages on discarded PWBs reutilization owing to its lower investment and operation cost,less secondary pollution,and have been the main research object of today.In this paper,the major physical processes for waste PWBs treatment developed in recent years were discussed.The advantages,disadvantages,key technologies as well as equipment of each process were analyzed and compared.Moreover,the paper recommended an approach to evaluation of reutilization effect through integrated efficiency and weighted environment. |
