An apparatus and method for producing a product, such as hydrogen halide gas or sulfuric acid, in a regenerator furnace subsystem from a waste containing a non-gasifiable impurity. The method of the invention includes directing a waste, containing a non-gasifiable impurity into a reaction zone, containing a molten metal bath, in a reactor maintained under conditions sufficient to dissociate the waste and to form a gasified feed component and a non-gasifiable impurity. The gasified feed component is then directed from the reactor to a regenerator furnace subsystem, maintained under conditions sufficient to convert the gasified feed component to the desired product. The apparatus of the invention includes a reactor having a waste inlet and a gaseous effluent, a reaction zone containing a molten-metal bath for dissociating the waste, containing a non-gasifiable impurity, and forming a gasified feed component, and a lance for injecting the waste into the reaction zone. The apparatus also includes a regenerator furnace subsystem, for converting the gasified feed component to the desired product, and a means for directing the gasified feed component from the reactor into the regenerator furnace subsystem.
