New solutions for reusing nonmetals reclaimed from waste printed circuit boards

Abstract

In waste printed circuit boards (PCBs) recycling fields, how to recycle and reuse nonmetals is a challenging problem, and there is no preferable solutions up to now. This paper presents new methods for reusing nonmetals reclaimed from waste PCBs. Nonmetals are used to make formative models, compound boards or related products. When compared with traditional materials, such as talc and silica powder, PCB nonmetals improve the mechanical features of these products greatly with comparable tensile and shearing strength and 30 percent larger flexural strength, which indicates good application prospect for its undoubted potential.
