A method for generating electricity in which sludge is anaerobically digested to form a gas mixture of methane and carbon dioxide and a residue of digested sludge. Water is removed from the digested sludge to form dewatered sludge, which, in turn, is gasified to form a gaseous composition which includes carbon monoxide and hydrogen. The gas mixture containing methane and carbon dioxide produced in the anaerobic digestion step is mixed with the gas mixture containing hydrogen and carbon monoxide from the gasification step and burned in an apparatus, such as a micro-turbine, for generating electricity. The non-carbonaceous fraction of the sludge is melted during the gasification step and rendered environmentally benign.

Conversion of sewage sludge into electric power

This invention relates to thermo-chemical remediation and decontamination of sediments and soils contaminated with organic contaminants as well as inorganic materials with subsequent beneficial reuse. Novel environmentally stable products of commercial value are produced when certain additives such as calcium and metal oxides are mixed with the contaminated materials. In the process, the mixture is heated to 1150.degree. C..about.1500.degree. C. to produce a molten reaction product with at least part of an excess amount of oxygen mixture or air is continuously bubbled through the melt in order to provide mixing and achieve high thermal destruction and removal efficiencies of the organic contaminants. The melt is then quickly quenched in moist air, steam, or water to avoid the transformation of the amorphous material into crystals. The inorganic contaminants such as chromium, nickel, zinc, etc. are incorporated and completely immobilized within the amorphous silicate network. Atmospheric emissions resulting from this process are nontoxic and capable of meeting currently specified health and environmental requirements.

The amorphous material can be pulverized to yield a powder which evinces cementitious properties either by reaction with alkali solution or by blending it with other materials to produce blended cements. The compressive strengths of the concretes made from the powder of the subject invention and blends thereof are comparable to, or greater than the ASTM requirements for general purpose concrete applications. The powder of the subject invention, blended cements, and concrete/mortar derived therefrom also easily pass the EPA TCLP leach test to achieve environmental acceptability.
