ABSTRACT:
A method and system for detoxification of waste materials, comprising incineration of the waste materials followed by additional contaminant reduction steps. The waste material is separated into solid and liquid portions that are fed separately into a combustion chamber wherein they are exposed to a plasma arc torch to affect combustion, producing a gaseous emissions stream and an obsidian residue. The gaseous emissions stream passes through an emissions control unit to eliminate acid gases, metals, and particulates, producing a cleansed exhaust gas and an emissions residue. The emissions residue is passed through an electroplating unit to reclaim metals. The obsidian residue is pulverized and then treated by a chemical process, or passed through the electroplating unit, to reduce the concentration of unbound barium contained therein, producing an inert obsidian residue that is free of toxic levels of all contaminants.
