Abstract: Apparatus and a process are provided for converting and/or removing harmful constituents from solid hazardous or other undesirable waste material by heating the waste in a reactor in the presence of a continuous flow of oxygen and waste metals, wherein the waste material becomes a molten metal oxide bath which when solidified, has a spinel structure to chemically bond harmful constituents within the spinel structure by crystal chemical substitution. The resulting metal oxides are environmentally acceptable. A substantially gaseous effluent which may contain particulate material is also generated. The effluent is conducted through a high temperature zone to destroy organic and other harmful constituents influenced by temperature and dwell time. The effluent is further processed through an emissions treatment system to achieve acceptable environmental quality.

Abstract: Harmful constituents are removed from solid hazardous waste material by heating the waste in the presence of a continuous flow of oxygen until the waste material becomes an agitated molten aggregate and generates effluvia. The effluvia is conducted through a high temperature zone to destroy organic and other harmful constituents. The effluvia is further processed to achieve acceptable environmental quality. The effluvia processing includes a dual reburn/heat exchanger compartment. The generated molten aggregate is thoroughly mixed and hardens into a ceramic-like aggregate which is environmentally safe.
