Waste-Printed Circuit Board Recycling: Focusing on

The waste from end-of-life electrical and electronic equipment has become the fastest growing waste problem in the world. The difficult-to-treat waste-printed circuit boards (WPCBs), which are nearly 3–6 wt % of the total electronic waste, generate great environmental concern nowadays. For WPCB treatment and recycling, the mechanical–physical method has turned out to be more

Recycling of Waste Printed Circuit Boards by Microwave

The combination of microwave-induced pyrolysis and mechanical processing is a promising way to recycle the waste printed circuit boards (WPCBs). In pyrolysis, WPCBs yield an average of 78.6 wt.% solid residues, 15.7 wt.% oil, and 5.7 wt.% gas. The solid residues are rich in metals; the oil is abundant with phenol and substituted phenols which can be reclaimed as chemicals or fuels; and the gas
