Thompson, J

A method is described of selectively capturing nuisance chemical components within the residual ash of a combusted mixture of waste compounds. The method consists of the steps of: (a) forming a combustible mixture from: (i) a nuisance waste component, which nuisance waste contains a material including at least one of the group consisting of lead, chromium, manganese, cadmium, beryllium, barium, selenium, arsenic, vanadium, antimony, bismuth, strontium, zirconium, germanium, copper, nickel, zinc, aluminum, sulfur, hydrocarbon, biological wastes and mixtures thereof; (ii) a heating value component; and (iii) a neutralizing component consisting of the oxides, hydroxides and carbonates of calcium, magnesium, and sodium, and at least one of SiO/sub 2/, Al/sub 2/O/sub 3/, Fe/sub 2/O/sub 3/, ZnO and mixtures thereof; (b) pressing the combustible mixture at a pressure sufficient to form a structurally stable solid having a net heating value of at least 200 btu/lb of the solid; and (c) converting the nuisance waste components to compounds resistant to water extraction by burning the combustible mixture, the neutralizing component being selected to cause the nuisance components to form the compounds resistant to water extraction.
