Description

<p>PCB （polychlorinated biphenyl） toxicity has been widely recognized by society since the 1968 “Kanemi Oilosis Incident”, and the “Manufacturing of PCBs in accordance with the Law Concerning the Examination of Chemical Substances and Production Regulations” enacted in 1974 In principle, imports were prohibited.</p><p>In 2001, the “Special Measures Law for Promotion of Proper Treatment of Polychlorinated Biphenyl Waste （PCB Special Measures Law）” was enacted, and high–concentration PCB waste was treated as a treat ment facility of Intermediate Storage and Environmental Safety Corporation （JESCO）. Chemical treatment is underway in Japan, and the treatment deadline will be reached step by step.</p><p>On the other hand, in the year following the enforcement of the PCB Special Measures Law（ 2002）, PCBs were included in the insulation oil of electrical equipment that was originally said not to use PCB, ex ceeding the standard value of 0.5 mg/kg （0.5 ppm）. The existence of what has been found.</p><p>In November 2009, the Ministry of the Environment positioned these as “micro PCB–contaminated waste electrical equipment, etc.”, and so far, they have been detoxifi ed by incineration or cleaning at private indus trial waste treatment facilities.</p><p>In August 2012, PCB contaminants with a PCB concentration of 5,000 mg/kg （0.5％） or less （waste con taining low–concentration PCB） were also added to the treatment objects, and these were collectively called “low–concentration PCB waste”.</p><p>As of the end of June 2019, 34 companies were certifi ed as detoxifi cation treatment facilities by the Minister of the Environment, and 5 facilities were licensed by prefectural governors for detoxification treatment of low–concentration PCB waste.</p><p>This paper introduces the efforts to detoxify low–concentration PCB waste in the DOWA Ecosystem Group, which started in 2006, and the detoxification treatment of PCB contaminants such as PCB–containing coatings, which have recently been attracting attention.</p>
