ABSTRACT:
A system including a method and apparatus for treating waste containing organic contaminants which includes a direct fired, countercurrent, rotary kiln providing a soaking zone having an oxidizing atmosphere through which the materials being treated are passed after the unwanted organics are removed, and a secondary combustion chamber for oxidizing gases containing vaporized or pyrolyzed organics in which the organics are burned and are subjected to high temperatures for a holding time sufficient to effect destruction of the organic contaminants. The system includes means to minimize off-gas so as to make possible a reduction in size of the equipment employed.
