    Abstract: A soil cleaning method (phytoremediation) of absorbing a contaminating substance contained in a contaminated soil by a plant to clean the soil. An object of the present invention is to provide a method of cleaning a contaminated soil which performs cleaning of a soil containing heavy metals in a shorter term than before and, at the same time, utilizes phytoremediation having little influence on the environment. The object is attained by absorbing heavy metals by a plant of Polygonaceae family, Fagopyrum genus, and, at the same time, adding a biodegradable chelating agent to a contaminated soil in order to assist the absorption. And, a biodegradable chelating agent having the high heavy metal dissolving out ability not only enhances the cleaning efficacy but also reduces secondary influence on the environment.

  • Patent number: 7786339
    Abstract: A method of removing organic contaminants from surfaces of solid wastes is disclosed. The method includes the steps of forming a TiO2 sol; mixing the solid wastes and the TiO2 sol by stirring. Furthermore, the mixture undergoes photo-catalytic remediation under illumination of a UV source prior to a solid-liquid separation process of the illuminated TiO2 sol and solid wastes.

  • Patent number: 7772452
    Abstract: A process for recovery of the silica present in the separators located between the elements of lead-acid batteries characterized in that it comprises the following operations: a) washing the heavy plastics to remove the lead compounds and other foreign bodies, b) separating the plastics from the washing solution, c) lead recovery and regeneration of the washing solution, d) rinsing of the plastics, e) drying of the plastics, f) separation of the granular plastics from the thin plastics (polyethylene with silica filler, PVC, fabrics) by drawing them up in a flow of air making use of the shape effect, g) separation of the PVC and fabrics from the polyethylene with silica filler through fragmentation, h) pyrolysis of the polyethylene with silica filler, i) cracking of the pyrolysis gases and vapours in order to reduce their molecular weight and render them more suitable for handling and combustion to provide the heat necessary for pyrolysis, j) oxidation of the pyrolysis residue to remove carbonaceous residues a

  • Patent number: 7662759
    Abstract: Decontamination formulations with an additive for enhancing mold remediation. The formulations include a solubilizing agent (e.g., a cationic surfactant), a reactive compound (e.g., hydrogen peroxide), a carbonate or bicarbonate salt, a water-soluble bleaching activator (e.g., propylene glycol diacetate or glycerol diacetate), a mold remediation enhancer containing Fe or Mn, and water. The concentration of Fe2+ or Mn2+ ions in the aqueous mixture is in the range of about 0.0001% to about 0.001%. The enhanced formulations can be delivered, for example, as a foam, spray, liquid, fog, mist, or aerosol for neutralization of chemical compounds, and for killing certain biological compounds or agents and mold spores, on contaminated surfaces and materials.

  • Patent number: 7589248
    Abstract: Mercury is removed from contaminated waste by firstly applying a sulfur reagent to the waste. Mercury in the waste is then permitted to migrate to the reagent and is stabilized in a mercury sulfide compound. The stable compound may then be removed from the waste which itself remains in situ following mercury removal therefrom.

  • Patent number: 7468469
    Abstract: A dissolved oxygen releasing blend is disclosed utilizing magnesium peroxide blended with powdered Bentonite and/or vegetable oil. The Bentonite (or other clay material) reduces the hydraulic conductivity of magnesium peroxide, thereby reducing the rate of magnesium peroxide disassociation.
