Disposal treatments of printed circuit board (PCB) waste recently seem to be improper since they all produce a secondary pollutions such as acidification of the soil and heavy metal leached into ground water from landfill and toxicant gasses generates from incineration and material combustion. At present the disposal treatment processes for nonmetallic fraction from PCB waste that have been separated after precious metal separation process are only combustion, landfill and material reused. The most important point is that this nonmetallic fraction from PCB waste can be recovered. Hence, this is a challenge to expose a further separation of materials and materials recovery. From the environmental friendly viewpoint, the only solution to reduce PCB waste problem sustainably is to address the waste material with a proper material recycling technology. The purpose of this study is to determine the suitability of using pyrolysis based recycling as well as to demonstrate its development to be able to process with NMF from PCB. Moreover, the aim is to point out that pyrolysis method can be used as PCB waste disposal treatment and show that now it is an sustainable alternative disposal option for the PCB waste material.
