Abstract: The present invention provides a method of processing organic waste (D) in divided solid and/or liquid form, the method being implemented in a single reactor (1) containing a bath of molten glass (V) surmounted by a gas phase (G), the method comprising incinerating said waste (D) in the presence of oxygen at the surface (S) of said bath of molten glass (V), and in vitrifying said incinerated waste (D) in said bath of molten glass (V). In said method, and in characteristic manner, in addition to the oxygen delivered as oxidizer into said gas phase (G), oxygen is also injected into said bath of molten glass (V) in a quantity that is sufficient to minimize or to avoid any formation of metal within said bath of glass (V); advantageously in a quantity that is sufficient to minimize or to avoid any formation of metal within said bath of glass (V) and also to subject said bath of glass (V) to moderate stirring.

Abstract: The present invention provides a method of processing organic waste (D) in divided solid and/or liquid form, the method being implemented in a single reactor (1) containing a bath of molten gas (V) surmounted by a gas phase (G), the method comprising incinerating said waste (D) in the presence of oxygen at the surface (S) of said bath of molten glass (V), and vitrifying said incinerated waste (D) in said bath of molten glass (V). In characteristic manner, in said method, said waste (D) is introduced into said reactor (1) in association with dual cooling; the device (5) for feeding said reactor (1) with said waste (D) is cooled on its side adjacent to the gas phase (G), advantageously by the circulation of at least one is cooling fluid maintained at a temperature higher than the dew point of said gas phase (G), and it is also cooled, advantageously independently, on its side adjacent to the incoming waste (D).
