  • Patent number: 10632645
    Abstract: A method of treating an elongate wood member is provided, the wood member having an outer surface and a cross-section. The method includes (1) forming a plurality of holes into the outer surface of the wood member; (2) introducing a treatment composition which includes a boron-containing compound into the plurality of holes; and (3) steam treating the wood member for a duration of from about 15 minutes to about 24 hours, the steam having a temperature of from about 80° C. to about 150° C. The steam treatment causes the boron-containing compound to diffuse from the formed holes into the cross-section of the wood member.

  • Publication number: 20160263771
    Abstract: A method for removing hazardous air pollutants and contaminants from a wood product is disclosed. In a first step, a contaminated wood product is placed in a treatment vessel. This wood product includes an initial amount of an absorbed contaminant, selected from the group consisting of creosote, a mixture of pentachlorophenol and a carrier oil, a mixture of copper naphthenate and a carrier oil, and combinations thereof In a second step, the wood product is heated to a treatment temperature sufficient to evaporate at least a portion of the absorbed contaminant from the wood product but insufficient to pyrolyze the wood product. The wood product is then maintained at the treatment temperature for a period of time sufficient to reduce the absorbed contaminant in the wood product to a final amount which is less than about 20% of the initial amount. Optionally, the desorbed wood may then be treated with a chemical to remove inorganic impurities that are detrimental during thermochemical conversion of biomass.

  • Patent number: 8119031
    Abstract: Preservative composition for lignocellulosic-based composites providing rapid and long-lasting protection against insect and fungal attack, in both low and high moisture environments, through the use of a combination of higher solubility and lower solubility borates. Pesticidal amounts of a lower solubility borate and a higher solubility borate are combined before or during their incorporation into a lignocellulosic-based composite. Useful low solubility borates include copper borate, zinc borate and barium metaborate. Useful high solubility borates include boric acid, boric oxide, ammonium borate and alkali metal borates such as sodium borate. Some alkaline earth metal borates, including calcium borates, calcium magnesium borates, magnesium borates and calcium sodium borates, are of intermediate solubility and may be used effectively as either a low soluble or high soluble borate depending on the combination used.

  • Publication number: 20110256196
    Abstract: The present disclosure provides a method for killing arthropods. According to one embodiment of the present disclosure, the method preferably includes providing a pesticide composition which includes from about 0.01 to about 0.8 percent, by weight, of a surfactant and from about 0.2 to about 15 percent, by weight, of a boron-containing component. The pesticide composition is applied to a absorbent material which is infested with arthropods, so that the pesticide composition is adsorbed by the absorbent material in an amount sufficient to kill arthropods. The arthropods contact the absorbent material and are killed by the adsorbed pesticide composition.

  • Publication number: 20080305071
    Abstract: The present disclosure provides a method for treating a contaminated surface. According to one embodiment of the present disclosure, the method preferably includes a first step of providing a cleaning composition which includes from about 0.002 to about 2 percent, by weight, of a cationic surfactant which is capable of acting as a microbial biocide and from about 0.05 to about 5 percent, by weight, of a boron-containing component which is capable of acting as both a microbial biostat and an insecticide. This cleaning composition is applied to the surface so as to substantially remove contaminants from the surface while, leaving a residual amount of the cleaning composition on the surface to act as a biostat.

  • Patent number: 7163974
    Abstract: Lignocellulosic-based woodfiber-plastic composite products containing a pesticidal amount of calcium borate is resistant to attack by wood destroying fungi and insects. The preferred calcium borates are the calcium polytriborates having a CaO:B2O3 molar ratio of about 2:3 and calcium hexaborates, having a CaO:B2O3 ratio of 1:3. Composites can be produced by combining the calcium borate with particles of the lignocellulosic material and the thermoplastic resin binder, and heating and extruding the resultant mixture through a die to form the composite product.
