Waste printed circuit boards (WPCBs), as the main component of the waste, are significant source of base and precious metals especially copper and gold. Printed circuit boards (PCBs) are currently being dumped in landfills or incinerated which is causing a serious environmental harm in the form of toxic gases or leached hazardous compounds.
28/03/2017 · With the development of technologies and the change of consumer attitudes, the amount of waste electrical and electronic equipment (WEEE) is increasing annually. As the core part of WEEE, the waste printed circuit board (WPCB) is a dangerous waste but at the same time a rich resource for various kinds of materials. In this work, various WPCB treatment methods as well as WPCB .
01/02/2012 · Electronics waste is becoming a major global issue. Huge accumulation of ewaste and their recycling through primitive means for extraction of precious metals are real concern in the developing countries due to presence of hazardous materials in ewaste. Recycling of ewaste through appropriate technologies is, however, considered to be a profitable business as the printed circuit boards .
