ABSTRACT:
A system for the destruction of organic waste material such as halogenated organic compounds, e.g., PCB's and related waste organic matter, comprises subjecting the waste material to reduction with a gaseous reducing agent, preferably hydrogen, at a temperature above about 600.degree. C. and thereafter subjecting the hot reaction mixture thus obtained to oxidation with a gaseous oxidizing agent at a temperature above about 1000.degree. C. The combined reduction followed by immediate oxidation is effective in achieving substantially complete breakdown of the halogenated compounds to substantially non-noxious gases. The system includes a reduction vessel wherein hydrogen is used directly in intimate mixing relation with the pulverized waste material, and after completion of a residence time sufficient to reduce the organic compounds, the gaseous by-products pass to an adjacent combustor for oxidation therein.
