Hazardous or toxic waste destruction or containment inventions 05/06

20060111603 - Storage of hazardous materials: A nuclear material is encapsulated by treating the material with an encapsulant that includes a cementitious material and curing the cementitious material. The nuclear material includes uranium metal, Magnox fuel elements, and/or fuel element debris....

20060111604 - Method for applying asbestos digestion chemical to asbestos-containing materials: A method for applying liquid, foam and/or gel forms of asbestos digestion chemicals through painted, coated or otherwise protected or encapsulated surfaces of asbestos-containing materials. The method includes forming an injection aperture in the encapsulating material and contacting the hazardous asbestos-containing material with asbestos digestion material through the injection aperture....

20060106272 - In-situ treatment of asbestos-containing material: The present invention relates to methods for the in-situ treatment of ACM containing chrysotile asbestos using a polycarboxylic acid such as oxalic acid. The polycarboxylic acid is introduced to the ACM while it remains substantially in place, or “in-situ,” and assists in converting the asbestos to a non-asbestos material. When...

20060094920 - Calcium-sodium polysulfide chemical reagent and production methods: A calcium-sodium polysulfide chemical reagent and methods for producing the reagent. The reagent is a blend of calcium polysulfide and sodium polysulfide that can be prepared using various types, sources and ratios of lime, elemental sulfur and sulfide ion using either virgin or waste materials. The reagent is amenable to...

20060094921 - Method for chemically stabilizing waste materials containing multivalent oxyanions: A method of chemically stabilizing multivalent oxyanions in residue materials such as wastes from glass manufacturing facilities which method involves adding to the residue material cement, lime and aluminum sulfate to form a clay-like material having a low leachability and permeability to water. Calcium polysulfide or other sulfide bearing materials...

20060094922 - Sonication treatment of media containing halogenated organic compounds: The invention consists of a method for treating media containing halogenated organic compounds (HOCs) by: a) combining the media with a fluid containing one or more liquid hydrocarbons to form a media/fluid mixture; b) sonicating the mixture at audio frequency to extract HOCs from the media into the fluid; and...
