These days, every electronic device contains one or more printed circuit board and as technology progresses, so will the number of printed circuit boards out there.
· Nonmetals reclaimed from waste printed circuit boards (PCBs) are used to replace wood flour in the production of wood plastic composite (WPC). To evaluate property durability against weather exposure, the effects of accelerated aging process on the properties of WPC are investigated. The results show that filling of nonmetals in WPC improves the flexural strength and tensile strength, and

From a literature review (leaching of gold ores, mostly), it was found that there are two research lines. Some authors worked with lower concentrations of thiosulfate and ammonium for a leaching time of 4 hours, whereas others worked with higher concentrations of thiosulfate and ammonium and a leaching time of 24 hours (O'Malley, 2002 O'Malley, G. P. Recovery of Gold from Thiosulfate
· Mechanical recycling can be considered as a valid alternative to recover plastics from mobile phones. PCBs of mobile phones are composed of different materials, mainly metals, plastics and ceramics, making more difficult their recycling. PCB can be categorized in three classes single layer, double layer or multi-layer (Kasper et al., 2011b). PCBs from mobile phones are classified as “rich
· The next step is to crush the circuit boards into powder and separate the copper and plastic. Read more Meituan Dianping steps up recycling drive amid deluge of plastic waste in China
Circuit Board with All Components Removed. Cutting of the Circuit Board. Once all the components have been removed, you can begin the process of making customised breakout boards or even customised circuit boards. Start by marking the board with a permannent marker pen. Cut the board to your requirement using a Hacksaw.
