Patent number: 7276468Abstract: A decontamination formulation and method of making that neutralizes the adverse health effects of both chemical and biological compounds, especially chemical warfare (CW) and biological warfare (BW) agents, and toxic industrial chemicals. The formulation provides solubilizing compounds that serve to effectively render the chemical and biological compounds, particularly CW and BW compounds, susceptible to attack, and at least one reactive compound that serves to attack (and detoxify or kill) the compound. The formulation includes at least one solubilizing agent, a reactive compound, a sorbent additive, and water. A highly adsorbent sorbent additive (e.g., amorphous silica, sorbitol, mannitol, etc.) is used to “dry out” one or more liquid ingredients into a dry, free-flowing powder that has an extended shelf life, and is more convenient to handle and mix in the field.Type: GrantFiled: December 18, 2003Date of Patent: October 2, 2007Assignee: Sandia CorporationInventor: Mark D.

Examples of suitable applications include disinfection of food processing equipment, disinfection of areas containing livestock, mold remediation, sterilization of medical instruments and direct disinfection of food surfaces, such as beef carcasses. The formulations include at least one reactive compound, bleaching activator, inorganic base, and water. The formulations can be packaged as a two-part kit system, and can have a pH value in the range of 7-8.Type: GrantFiled: January 27, 2004Date of Patent: September 18, 2007Assignee: Sandia CorporationInventors: Mark D.

Patent number: 7166758Abstract: Decontamination of nuclear facilities is necessary to reduce the radiation field during normal operations and decommissioning of complex equipment. In this invention, we discuss gel and foam based diphosphonic acid (HEDPA) chemical solutions that are unique in that these solutions can be applied at room temperature; provide protection to the base metal for continued applications of the equipment; and reduce the final waste form production to one step. The HEDPA gels and foams are formulated with benign chemicals, including various solvents, such as ionic liquids and reducing and complexing agents such as hydroxamic acids, and formaldehyde sulfoxylate. Gel and foam based HEDPA processes allow for decontamination of difficult to reach surfaces that are unmanageable with traditional aqueous process methods. Also, the gel and foam components are optimized to maximize the dissolution rate and assist in the chemical transformation of the gel and foam to a stable waste form.Type: GrantFiled: March 26, 2005Date of Patent: January 23, 2007Inventors: Luis Nunez, Michael Donald Kaminski

Patent number: 7034197Abstract: A liquid reactant metal alloy includes at least one chemically active metal for reacting with non-radioactive material in a mixed waste stream being treated. The reactant alloy also includes at least one radiation absorbing metal. Radioactive isotopes in the waste stream alloy with, or disperse in, the chemically active and radiation absorbing metals such that the radiation absorbing metals are able to absorb a significant portion of the radioactive emissions associated with the isotopes. Non-radioactive constituents in the waste material are broken down into harmless and useful constituents, leaving the alloyed radioactive isotopes in the liquid reactant alloy. The reactant alloy may then be cooled to form one or more ingots in which the radioactive isotopes are effectively isolated and surrounded by the radiation absorbing metals. These ingots comprise the storage products for the radioactive isotopes. The ingots may be encapsulated in one or more layers of radiation absorbing material and then stored.Type: GrantFiled: January 29, 2002Date of Patent: April 25, 2006Assignee: Clean Technologies International CorporationInventor: Anthony S. Wagner

Patent number: 6984769Abstract: A reactive coating composition and method for treating a surface including heavy metals by applying the reactive coating composition to the surface. The surface can be, for example, a paint layer containing heavy metals. The reactive coating composition includes a stabilizing agent to stabilize the heavy metal and a permeability enhancing agent to increase the permeability of the paint layer, facilitating the reaction of the heavy metal with the stabilizing agent. The structure including the treated paint layer can be left in place or can be disposed in a non-hazardous landfill.Type: GrantFiled: April 3, 2003Date of Patent: January 10, 2006Assignee: MT2, LLCInventors: James Barthel, Mark A.

Patent number: 6841515Abstract: This invention relates to the production and use of encapsulated and/or concentrically-constructed fertilizer or bioremediation granules such as, for example, granules of 0.5 mm to 10 mm in diameter constructed so that there are at least two components to the granule including a core with a surrounding capsule or a core with one or more concentric layers that are distinguishable from the core with respect to nutrient content, density, hardness, solubility, composition, microbial content and permeability, as in permeability to odors or the permeability of nutrients that might volatize to the atmosphere or leach into the soil. The basic idea was to create a method for manufacturing and using fertilizer granules, which incorporate multiple concentric layers or a core plus an encapsulating outer layer.Type: GrantFiled: January 22, 2002Date of Patent: January 11, 2005Assignee: Unified Enviromental Services Group, L.L.C.Inventor: Jeffrey C.

Patent number: 6812174Abstract: The invention relates to methods of vitrifying waste and for lowering the melting point of glass forming systems by including lithia formers in the glass forming composition in significant amounts, typically from about 0.16 wt % to about 11 wt %, based on the total glass forming oxides. The lithia is typically included as a replacement for alkali oxide glass formers that would normally be present in a particular glass forming system. Replacement can occur on a mole percent or weight percent basis, and typically results in a composition wherein lithia forms about 10 wt % to about 100 wt % of the alkali oxide glass formers present in the composition. The present invention also relates to the high lithia glass compositions formed by these methods.Type: GrantFiled: May 19, 2003Date of Patent: November 2, 2004Assignee: Westinghouse Savannah River CompanyInventors: Carol M.
