Abstract: A method for manufacturing a processed asphalt suspension is provided. The method includes dry grinding shingle waste material to a particle size of less than 1 cm, forming ground recycled shingle material, introducing virgin asphalt into a heated slurry tank and mixing the ground recycled shingle material with the virgin asphalt in the heated slurry tank, forming a mixed asphalt slurry, introducing the mixed asphalt slurry into a wet grinding machine, and recovering a processed asphalt suspension comprising particles having a size no greater than about 200 microns. Roofing and paving products manufactured from the processed asphalt suspension are also provided.

Abstract: A method of removing organic components from a mixture containing organic and inorganic components which method involves providing an induction heated screw conveyor having an auger and passing the mixture through the induction heated screw conveyor while inductively heating the auger so as to heat the mixture in the induction heated screw conveyor primarily from the center of the induction heated screw conveyor. The mixture is heated to a temperature that is sufficient to cause the organic components in the mixture to separate from the mixture as a vapor. The oxygen concentration in the induction heated screw conveyor is controlled so as to gasify the organic components. The gasified organic components are removed and the remaining inorganic components are collected.

Abstract: A method of separating metals that are physically or structurally combined in assemblies which includes the steps of: providing at least one assembly that comprises two or more different metals that are physically or structurally combined; heating the at least one assembly in a tunnel kiln furnace to melt at least one of the different metals while maintaining at least one of the different metals in a solid state; and separating the at least one of the different metals that was melted from the at least one of the different metals that was maintained in the solid state. According to one embodiment the assemblies are “copper meatballs.” Also disclosed is a system for separating metals that are physically or structurally combined in assemblies which system includes a tunnel kiln furnace and processing containers or processing containment assemblies into or onto which the assemblies are loaded and transported through the tunnel kiln furnace in.

Abstract: A reagent mixture comprising a hydrocarbon emulsion and an adhesion promoter which is used to agglomerate carbonaceous material particles from coal slurries of settling ponds or coal processing plants. The reagent mixture inhibits or avoids co-agglomeration of noncombustible impurities such as clay present in the slurries. The reagent mixture is provided as at least one of a slurry, a suspension, an emulsion and a solution which is contacted with the coal slurry.

Abstract: A method of decreasing the concentration of nitrogen oxides in flue gases emitted into the atmosphere from combustion systems that burn carbonaceous materials which involves pretreating carbonaceous material particles with vanadium, titanium and ammonia. In the case of coal particles, vanadium, titanium dioxide and ammonium acetate are used to coat the coal particles. The vanadium and titanium dioxide are applied as substantially uniform coatings on the surfaces of the coal particles by incorporating the vanadium and titanium dioxide in emulsions or suspensions.
