20070225540 - Method and apparatus for mitigating mercury vapor emissions during transportation of mercuty containing universal waste: An apparatus for mitigating mercury vapor emissions during transportation of mercury containing universal waste between locations. The apparatus includes a container having a bottom, sidewall structure extending from the closed bottom, and an opening for allowing the mercury containing universal waste to be inserted into the container. The opening in... Agent: John W. Harbst

20070225541 - Method for stabilization of heavy metals and odor control with dicalcium phosphate dihydrate powder: This invention provides a method for stabilization and treatment of heavy metal bearing materials and wastes subject to acid leaching tests or leach conditions and odor limits by addition of acid semi-soluble DiCalcium Phosphate DiHydrate such that the leaching potential is inhibited to desired levels and odors are reduced to... Agent: Keith E. Forrester

20070225542 - Treatment of in ground chromium ore processing residue: In methods for treatment of in ground chromium ore processing residue contamination, ferrous sulfide is provided as a substantially insoluble material in the residue deposit. The ferrous sulfide accordingly may remain substantially in place, in the pores of the soil or residue, even over long periods of time, regardless of... Agent: Perkins Coie LLP

20070225543 - Sonication treatment of media containing halogenated organic compounds: The invention consists of a method for treating media containing halogenated organic compounds (HOC's), including Persistent Organic Pollutants (POP), 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; and c) treating the fluid... Agent: Vermette & Co.

20070219402 - Encapsulation of hazardous waste materials: The invention provides a method for the encapsulation of uranium metal which comprises treating the metal with an encapsulant which comprises a cementitious material and curing the cementitious material, the process additionally comprising the provision of means for the minimisation of the corrosion of the metal. Suitable modes for the... Agent: Seyfarth Shaw LLP

20070219403 - Method for direct solidification and stabilization of liquid hazardous wastes containing up to 100,000 mg/l of arsenic: The present invention relates to a method for direct treatment of liquid wastes containing up to 10% or 100,000 mg/L of arsenic by solidification/stabilization in a relatively cost effective and environmentally safe. The method also permits the simultaneous utilization other heavy metal bearing wastes (such as spent catalysts), in the... Agent: Dla Piper US LLP

20070219404 - Treating hazarous materials: Methods of treating hazardous materials, such as, for example, contaminated soils, are disclosed. In one aspect, a method may include treating a contaminated soil with a hazardous material treatment composition to form a resulting material. In one aspect, the hazardous material treatment composition may include mostly salt, and from 0.5... Agent: Blakely Sokoloff Taylor & Zafman

20070213577 - Method for stabilization of hazardous wastes with dilute acid semi-soluble dicalcium phosphate dihydrate powder: This invention provides a method for stabilization of heavy metal bearing materials and wastes subject to acid leaching tests or leach conditions by addition of acid semi-soluble DiCalcium Phosphate DiHydrate such that the leaching potential is inhibited to desired levels and the material or waste is free flowing, more permeable,... Agent: Keith E. Forrester

20070208208 - Methods for melting of materials to be treated: A process for melting material to be treated includes placing material to be treated in a container that may include an insulating lining, heating the material to be treated and melting the material to be treated, preferably allowing the melted material to cool to form a vitrified and/or crystalline mass,...
