There is growing demand in public opinion on retreated from the scientific community effort that
PCB-containing waste must be rapidly identified properly collected and properly destroyed in order to stem
their continued migration into the general environment. PCBs are highly stable organic compound. that are
either oily liquid or solid and are colorless to light yellow in color. there are no known natural sources of
PCBs. PCBs don’t burn early and are good electricity insulating material. they have been used widely at
coolants and lubricants in transformers, capacitors, and other electrical equipment. PCBs can be released into
the environment from hazardous waste sites that contain PCBs, illegal or improper umping of PCBs waste, and
leaks from electrical transformers containing PCBs. PCBs may be carried long distances in the air and they
remain in the air for approximately 10days.In water, a small amount at the PCBs may remain dissolved, but
most sticks to organic particles and sediments. PCBs in water build up in fish and marine mammal and can
reach levels thousands of times higher than the levels in water. One might get exposed to PCBs by using old
fluorescent lighting fixtures and old appliances such as television sets and refrigerators. Animal experiments have
shown that PCB mixture produce adverse health effects that include damage, skin irritations reproductive and
developmental effects, and cancer. The purpose of this paper is to review the existing thermal technologies to
treat PCBs presenting their limitation and some technical, environmental, social and economic criteria to choose
the most proper technique. In this study we investigated both the decomposition and unintentional formation of
polychlorinated biphenyl congener during thermal treatment plant such as plasma melting treatment and plasma
pyrolysis - melting treatment.
