Abstract:
The BCDP (Base Catalyzed Decomposition Process) is a process by which difficult-to-decompose organic chlorine compounds, such as PCBs, are chemically decomposed and dechlorinated. Pilot-plant tests for PCB contaminated soil were carried out. PCB contaminated soil (32 mg/kg-530 mg/kg) was decontaminated to a level (0.038 mg/kg-4.8 mg/kg) which satisfied the corresponding Japanese environmental standard which stipulates, "there must be no discharge of PCB containing leachate".
