PCB materials: Recycle, reuse, dispose? | EDN
After all, consumer demand for electronic devices is at an all time high, and each device contains one or more PCBs, therefore disposal of waste PCBs is a growing concern. Recycling PCBs is challenging, since a PCB contains several different chemicals, metals (including precious metals such as gold, silver and copper) and glass fibers.
Electronic waste or e-waste describes discarded electrical or electronic devices.Used electronics which are destined for reuse, resale, salvage, recycling, or disposal are also considered e-waste. Informal processing of e-waste in developing countries can lead to adverse human health effects and environmental pollution.. Electronic scrap components, such as CPUs, contain potentially harmful .
