There is disclosed a process for destroying halogenated hydrocarbons such as PCBs and PCBs in PCB containing fluids (e.g., Askarel) and oils (e.g., paraffin oil, transformer oil, etc.) at ambient temperature. The process comprises reacting halogenated hydrocarbons, such as PCB containing fluids or oils with a solid oxidant in the presence of a concentrated acid. Preferably, the solid oxidant is potassium permanganate and the concentrated acid is sulfuric acid. Destruction efficiency is as high as 99.95%.

Ambient temperature destruction of PCB wastes

This is disclosed a process for the decomposition of halogenated hydrocarbons including polychlorinated biphenyls (PCB) and chlorinated pesticides, as DDT and DDE. The process comprises microwave-mediated wet-ashing of the halogenated hydrocarbons(s) in controlled conditions to avoid an emission of noxious fumes from the reaction mixture. Preferably, the wet-ashing reagent is a 1:1 mixture of nitric acid and sulfuric acid.
