  • Patent number: 7083728
    Abstract: A method and system for treating at least bioorganic, organic, wastewater, and sewage sludge using recycle. The method of producing a treated sludge product comprises the following steps: (a) forming a sludge mixture by mixing untreated sludge with at least one alkaline material in an amount sufficient to raise pH of the sludge mixture to a level of at least about 12 and to increase percent solids in the sludge mixture to at least about 40% by weight; (b) forming a dried sludge mixture by drying the sludge mixture from step (a) in a direct or indirect dryer thereby increasing the percent solids thereof to at least about 50% by weight; (c) recycling a portion of the dried sludge mixture from step (b) to step (a); and (d) pasteurizing the dried sludge mixture from step (b) at a temperature at or above about 52° C. to form a treated sludge product. Exemplary applications for the treated sludge product include an agricultural liming agent, a soil conditioner, a fertilizer, a topsoil blend ingredient, and a fuel.

  • Patent number: 6883444
    Abstract: Processes and systems are provided that include introducing ammonia liberated from organic waste to a coal burner in a coal burning power plant, preferably for NOx removal at the power plant. The ammonia is preferably either ammonia liberated upon drying a mixture of organic waste and coal combustion by-products or ammonia liberated when organic waste is mixed with coal combustion by-products and one or more alkaline additives. Also provided are processes and systems of fueling a coal burner of a power plant with coal and either a dried mixture of organic waste and coal combustion by-products, or a mixture of organic waste, coal combustion by-products and one or more alkaline additives. The present invention is further directed to mixtures of either organic waste and coal combustion by-products, or mixtures of organic waste, coal combustion by-products and alkaline additives made by the processes of the present invention.

  • Patent number: 6752848
    Abstract: A method of disinfecting and stabilizing organic wastes where organic waste is intimately mixed with one or more mineral by-products to produce a mixture having a pH of less than about 9. The mixture is heated and dried to produce a stable, granular bio-mineral product that may be used for example, as a fertilizer, soil amendment or as a soil substitute. Also provided are stable, granular bio-mineral products formed by the methods of the present invention and fertilizers, soil amendments, and soil substitutes that include these stable, granular bio-mineral products. Further provided are systems for disinfecting and stabilizing organic waste, and systems for making a stable, granular bio-mineral product.

  • Patent number: 6666154
    Abstract: Methods and systems for treating organic waste, which include determining the ignition threshold temperature for the organic waste and at least one mineral by-product, selecting a ratio of organic waste:mineral by-product(s) based on the determined ignition threshold temperature, combining the mineral by-product(s) with the organic waste, so as to arrive at a mixture having the selected ratio of organic waste:mineral by-product(s); and drying the mixture of organic waste and mineral by-product(s) to produce organic waste solids.

  • Patent number: 6402801
    Abstract: A method is described for treating animal manures and other organic wastes to destroy pathogens, reduce noxious odors, and immobilize water-soluble pollutants, thereby producing a pasteurized, granular product useful as a soil amendment. In a described implementation, the solids content of the organic waste is raised to a predetermined level to create air-filled pore space, and the pH is raised sufficiently to liberate endogenous gaseous ammonia in the air-filled pores for a predetermined time. The level of gaseous ammonia is sufficient to significantly destroy pathogens in the manure. In addition, alkaline material and/or iron salts are added to the organic waste to render certain water-soluble pollutants insoluble.
