Research Progress on the Recycling Technology for Nonmetallic Materials from Wasted Printed Circuit Board

Mechanical treatment of waste printed circuit board in crushing - sorting to separate valuable metals component, will produce a large amounts of glass fiber resin powder (ie, non-metallic powders), which has become the problem of world's electronic waste disposal. In this paper, the present situation of non-metallic materials’ generation, treatment and disposal, reutilization technology and methods were surveyed and comparatively analysed. Combined with the analysis on the generation, component, interfacial and microstructure characteristics, a better available route for treatment on non-metallic materials was proposed.
