In India by contrast there are currently 178 formal e waste recycling/dismantling units recognized by CPCB using automated semi automated or manual operations these are located in different states as shown in Fig 4 Their total recycling capacity reported as 438085 62 MTA Metric Ton per Annum
Fig 2 shows the production of PCBs in different countries and regions China which shares nearly half of the total PCB industries market is the fastest growing nation in the PCBs production Currently waste PCBs account for ∼3 of the total E waste generated globally Dalrymple et al 2007 China alone considering the total E waste that is generated and imported more than
The parts mounted on printed circuit board PCB were liberated by underwater explosion and mechanical crushing The crushed PCB without surface mounted parts was carbonized under inert atmosphere at 873 K to recover copper The multi layered ceramic capacitors including nickel was carbonized at 873 K to recover nickel by the magnetic separation
Pyrolysis can be considered as an alternative method of recycling PCB because in the pyrolysis process heating without oxygen the organic part is decomposed to low molecular products liquids or gases which can be used as fuel or chemical source furthermore PCB changes brittle undergoes delamination easily crushed while the inorganic part such as glass fibre can keep fairly
