  • Process for processing waste incineration residues
    Patent number: 6059854
    Abstract: A method for processing solid waste incineration residues is disclosed in which the residues are introduced a steelworks slag bath in a sufficient amount so that the residues constitute from 15-45% by weight of the combined weight of the solid waste incineration residues and the steelworks slag bath. The residues are melted to effect the evaporation of heavy metals; which are drawn off from the steelworks slag bath to leave a heavy-metal-depleted slag bath. The residual bath is reduced with carbon carriers to form a slag phase and a pig iron phase. The slag phase can be granulated to produce mixed cement components.
