Abstract
The invention provides processes for decontamination of organic halides in asphalt-containing wastes, such as PCBs in asphaltic potting compounds. The processes may use hydrocarbon solvents to dissolve the asphaltic waste, and an alkali metal reactant, such as a sodium dispersion, to destroy the organic halides in the dissolved mixture.
