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 Finally, said phase, charged with molten/coated waste and/or with combustion products from said waste, is withdrawn from the reactor.

A process for destroying waste and/or rendering waste inert, which comprises:
- feeding at least one partially vitrifiable material into a reactor having a heating means which comprises at least one submerged burner;
- heating at least one partially vitrifiable material with said heating means;
- forming and maintaining in the reactor an at least partially liquid/foamy phase at a temperature of at least 800° C.;
- feeding into said liquid/foamy phase waste;
- wherein at least one melted and/or coated material or decomposition product is obtained by feeding waste into said phase;
- and
- discharging a final phase without separating particulate material from the final phase.
A process for destroying waste and/or rendering it inert, which comprises:
- feeding at least one partially vitrifiable material into a reactor having a heating means which comprises at least one submerged burner;
- heating at least one partially vitrifiable material with said heating means, leading to a molten glass;
- forming and maintaining in the reactor an at least partially liquid/foamy glassy phase at a temperature of at least 800° C.;
- feeding into said liquid/foamy phase waste comprising at least one inorganic component and/or at least one organic component;
- wherein said feeding waste occurs under the level of said liquid/foamy glassy phase,
- wherein at least one melted and/or coated material is obtained, said material being embedded in glass, and
- discharging a final phase without separating particulate material from the final phase.
