A method for economically separating chemical contaminants such as volatile organic chemicals (VOC's) and polychlorinated biphenyls (PCB's), even if the contaminants are present at low concentrations, from inert materials such as soils or sludges, comprising subjecting inert materials contaminated with chemical compounds to a temperature effective to volatilize the contaminants but below incineration temperature, with continuous removal of evolved vapors, for a period of time sufficient to effect the desire degree of separation of contaminants. The evolved vapors may be subjected to catalytic oxidation to destroy the volatilized chemical compounds.
