A method for disposing of a halogenated organic material includes the steps of partially oxidizing the halogenated organic material, a hydrocarbonaceous material, and a nitrogen compound with a free-oxygen containing gas and optionally with a temperature moderator in a synthesis gas generator under partial oxidation conditions. The partial oxidation produces a synthesis gas containing, among others, hydrogen halide and ammonia. The synthesis gas is then contacted with a quench medium which dissolves the hydrogen halide into the quench medium. The hydrogen halide and quench medium can be disposed of by the addition of a base to form a readily disposed metal salt of the halide.
