Abstract
The invention relates to a method for treating wastes, in particular from the production of mineral fibres such as fibreglass wool or rock fibres associated with organic binders and optionally with water or other metal and/or organic matters consisting in fusing a waste mass (9) by supplying a pure oxygen or an oxygen-enriched air in order to obtain a mineral material usable in the form of a vitreous raw material for glass melting and in inputting energy by means of at least one burner submerged under the waste mass (9). A device for carrying out said method is also disclosed.

- A method for treating waste to obtain a mineral material useable as a vitreous raw material in a glass melting process, comprising a step for melting a waste mass by the input, to said waste mass, of pure oxygen or oxygen-enriched air through feeding means, characterized in that energy is also added via at least one burner submerged under the waste mass, said burner being a device supplying at least one oxidizer and at least one gaseous fuel in which, or directly after which, these reactants are blended in order to create an exothermic combustion reaction and in that said means for feeding pure oxygen or oxygen-enriched air are placed on the support for said waste mass, said waste being of the glass wool or rock wool fiber type combined with organic binders and optionally water or other metallic and/or organic materials.
