Patent number: 8945351Abstract: 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.

Patent number: 8193000Abstract: A colorimetric test for determining the presence or absence of biodiesel in a diesel fuel sample. The colorimetric test involves adding concentrated sulfuric acid to a sample of diesel fuel and observing any color change of the sample. A darkening of the diesel fuel sample indicates the presence of biodiesel. The degree to which the color changes after the addition of the sulfuric acid is proportional to the amount of biodiesel in the sample and therefore can be used to determine the amount of biodiesel in the sample. The reagent(s), sample containers and any necessary color scale can be provided in a kit for field testing.Type: GrantFiled: December 17, 2008Date of Patent: June 5, 2012Assignee: Heritage Environmental Services, LLCInventor: Linda Osborn

Patent number: 8168696Abstract: Porous aggregates are coated with latex or water-based paints so as to lower the absorbility of the aggregates. When the paint-coated aggregates are mixed with an asphalt binder to produce an asphalt composition, the paint-coated aggregates absorb less of the asphalt binder, resulting in costs savings of the asphalt binder. In addition, the paint-coated aggregates avoid problems associated with selective absorption of components of the asphalt binder.Type: GrantFiled: May 19, 2008Date of Patent: May 1, 2012Assignee: Heritage Environmental Services, LLCInventor: Anthony J.
