Oct 30 2021 Printed circuit boards PCBs are difficult to recycle because of the layered structure of non metal i.e. epoxy resin glass fiber and copper. In this work we conducted a systematic investigation to effectively recover copper from PCB. A thermal treatment was employed for improving the crushing performance of PCB and conducted by varying the
The crushing of printed circuit boards has a great importance because the separation and the results obtained are closely related to the shredding and the size of cuts. PCBs contain copper foil are reinforced with fiberglass so the rigidity of these components is high. This feature makes them difficult to cut into small pieces.
In printed circuit boards the most common metal is copper in addition to metals such as gold aluminum nickel and lead many of which are rare metals. Therefore the recycling of e waste can not only protect the environment but also bring huge benefits.
