Abstract

A subject matter of the invention is a process for destroying waste and/or rendering it inert, in particular industrial, biological or farm-produce waste: use is made of a reactor provided with heating means comprising at least one submerged burner, and said reactor is fed with at least partially vitrifiable materials, which are heated with said heating means in order to form and to maintain, in the reactor, an at least partially liquid/foamy phase at at least 800° C. Then said waste is introduced into said phase in order for its organic components to be decomposed therein by combustion and/or its inorganic components to be melted or coated in said phase. Finally, said phase, charged with molten/coated waste and/or with combustion products from said waste, is withdrawn from the reactor.
