1. A method for top-charging a solid waste into a molten metal bath contained in a reactor, wherein the solid waste is dissociated into dissociation products that are subsequently oxidized to form a gaseous oxygenated product, comprising introducing said waste into the reactor through a refractory tube that extends within the reactor and into the molten metal bath, said refractory tube having a submergible end that is immersed in the molten metal bath and that has a lower opening at a terminal portion of the submergible end and at least one elevated opening, whereby a portion of the molten metal bath enters the refractory tube through the lower opening for dissociating the waste and for forming the gaseous oxygenated product, the gaseous oxygenated product passing out of the refractory tube through said elevated opening and being discharged from the reactor through a reactor outlet disposed above the molten metal bath.
