A Review on Printed Circuit Boards Waste Recycling Technologies and Reusing of Recovered Nonmetallic Materials
From the use of renewable resources and environmental protection viewpoints, recycling of waste printed circuit boards (PCBs) receives wide concerns as the amounts of scrap PCBs increases dramatically In recent years there has been increasing concern about the growing volume of end of life electronics and the fact that much of it is consigned to landfill w ithout any attempt being made to recyc...
متن کاملEnvironmental Impacts of Recycled Nonmetallic Fraction from Waste Printed Circuit Board
Recently in Thailand, the recycling process of waste printed circuit board (WPCB) has retained a large volume of nonmetallic fraction (NMF), which has entered the industrial waste stream and awaits an appropriate treatment to be suggested. The aim of this paper was to assess environmental impacts of the recycled nonmetallic fraction from waste printed circuit board in Thailand, using the ReCiPe...
متن کاملLeaching of Gold from the Waste Mobile Phone Printed Circuit Boards (PCBs) with Ammonium Thiosulphate
The rapid growth in the use of electronic equipments, combined with early obsolescence has contributed enormously to the generation of large quantity of electronic (e) waste. One such e-waste, the mobile phone printed circuit boards (PCBs) contain various precious metals which can be extracted by different hydrometallurgical routes. The present work deals with the recovery of gold using ammoniu...
متن کاملRecycling of Printed Circuit Boards
Printed circuit boards (PCBs) can be found in any piece of electrical or electronic equipment: nearly all electronic items, including calculators and remote control units, contain large circuit boards; an increasing number of white goods, as washing machines contains circuit boards for example in electronic timers. PCBs contain metals, polymers, ceramics and are manufactured by sophisticated te...
متن کاملPyrolysis of Printed Circuit Boards
Printed Circuit Board (PCB) is an essential component of almost all electrical and electron ic equipments. The rapid growth of the use of such equipments has contributed enormously to the generation of large quantity of waste PCBs. The WPCBs not only contain valuable metals but also a large variety of hazardous materials. Conventional treatments of such WPCBs have their own limitations. By pyro...
