· Fig. 3 shows the flow sheet for recovering copper from bare board of PCB by carbonization. Bare boards of 3–20 mm in size are crushed by using a biaxial shear cutter (for example 2010) and hammer crusher ( 2014). Boards are carbonized at 873 K for 1 h. Nitrogen gas is blown into the furnace to keep 2.5 of oxygen
· Besides supercritical water other supercritical fluids were also employed for the recycling of PCBs. al et al. used supercritical carbon dioxide as solvent with an additional small amount of water to separate the PCB components into copper foil glass fiber and polymer. The lack of formation of hydrocarbons and noxious substances commonly observed in PCB pyrolysis strengthens the environmentally-friendly nature of supercritical carbon dioxide recycling
