A method of using high temperature plasma to disintegrate waste containing titanyl phthalocyanine (TiOPc) comprises heating a mixture of titanyl phthalocyanine (TiOPc), a vitrifying material and optionally selected waste soil to a temperature of 1,220.degree. C. to 10,000.degree. C. until the mixture becomes a molten lava. The plasma breaks down the titanyl phthalocyanine and encapsulates the benign products in the lava that is chemically very stable. Since the titanyl phthalocyanine (TiOPc) is ...

Methods of treatment of cyanide-containing waste are provided. In particular, methods for treatment of spent potliner prior to landfill disposal are provided. These methods, which involve treatment of the waste with a mixture containing an aqueous oxidizing solution containing an agent, such as a metal chloride, that increases the oxidation potential of the solution, can be performed at ambient temperature and pressure.

A method for deactivating a toxic chemical agent comprising contacting said toxic chemical agent with an halogenated resin.

Improved apparatus and approaches are described for destruction of energetic materials. The approaches include hydrolysis of the energetic materials by combining a volatile base and water with the energetic materials. The unreacted base from the hydrolysis reaction mixture is recovered and reused for further hydrolysis of energetic materials. The apparatus include components suitable for recovering and reusing unreacted base.

Process for the environmentally appropriate degradation of chemical compounds which have one or more heteroatoms X, with X being F, Cl, Br, I, N, O or S, by cleavage of the C--X carbon-heteroatom bonds, characterized in that the chemical compounds or articles which contain the chemical compounds are treated with water vapor in the presence of an aluminum catalyst at 300.degree.-600.degree. C.

A method of disposing of hazardous volatile liquid organic waste materials that includes the steps of providing a dry free flowing solid material containing lime and preferably, an organic salt of calcium, magnesium or aluminum containing about 10 to 22 carbon atoms; stirring a volatile organic liquid waste material to be disposed of therein to form a non-aqueous paste; allowing the paste to harden into a solid form that does not release the waste liquids when 100 grams thereof are placed in a 4...

A method of decreasing nitrate nitrogen and volatile organic compounds in soil and groundwater by burying a fatty acid having 10 or more carbon atoms, an alcohol having 12 or more carbon atoms, an ester of a linear saturated fatty acid having 14 or more carbon atoms and a monohydric alcohol, an ester of a linear saturated fatty acid having 14 or more carbon atoms and a polyhydric alcohol, an ester of a fatty acid having 16 or more carbon atoms and glycerine, and the like in soil containing nitra...

The present invention relates generally to the destruction of chemical weapons. In particular, the present invention relates to methods for treating hydrolysates of chemical agents. In one embodiment, the present invention provides a method comprising oxidizing a hydrolysate of a chemical agent to produce an aqueous layer and an organic layer, the aqueous layer comprising an organophosphorus concentration and the organic layer comprising an organosulfur concentration, and separating the organic ...

A process for the low temperature, non-incineration decontamination of contaminated materials, such as chemical weapon components containing residual quantities of chemical warfare agents. The process includes the steps of (a) preparing a feed mixture containing the chemical weapon components and organic materials; (b) contacting the feed mixture with steam at substantially ambient pressure in a substantially dry first heated vessel for a period of at least about 15 minutes, the steam being at a...

A method for eliminating halogenated and non halogenated waste, whereby waste is reacted with products containing metal oxide in an oxygen-free medium at temperatures ranging from 800.degree. C. to 1100.degree. C.
