  • Concentrations of organic wood preservatives in wood chips produced from wood wastes

    We investigated the concentrations of wood preservatives in the wood chips produced in wood-waste processing facilities in 1988, 1998–1999, and 2001–2002. Among the wood preservatives used in the past in Japan, halophenols, including PCP, chlordane, and chlorpyrifos, had comparatively high detection rates and high average concentrations in the wood chips produced in 2001–2002. Aldrin and endrin ...

  • Pesticide removal from wastewater

    In this study, the removal of 2,2 ? dichlorovinyl ? o,o ? dimethyl phosphate (DDVP) from wastewater by adsorption was carried out. DDVP is an organophosphorus insecticide widely used in agriculture in Turkey. Adsorbents used in the study were agricultural waste straw, wood chips and ground corncobs. Adsorption of DDVP onto these materials from wastewater was evaluated by using a batch system. ...

  • Turning wood chips and sawdust into a valuable solid fuel

    RUF briquetting units are the economical solution for the processing of wood chips and sawdust. Where timber is planed, turned and sanded, manufacturers end up with large quantities of wood chips and sawdust. By briquetting this material, you can recover a valuable solid fuel. Where large quantities are produced, the single briquette pressing system developed by RUF GmbH is the most economical ...

  • Evaluation of passive reduction of nitrate from greenhouse effluent by planted bioreactors

    A number of pilot-scale gravel and wood-chip hybrid bioreactors planted with select species, together with unplanted units, were evaluated for their nutrient removal capabilities from the typical greenhouse effluent with high levels of nitrate and salts. Two levels of nutrient solution (high and low loading: HL/LL) were prepared to simulate the typical characteristics of the greenhouse ...

  • Denitrification in wood chip bioreactors at different water flows

    Subsurface drainage in agricultural watersheds exports a large quantity of nitrate-nitrogen (NO3–N) and concentrations frequently exceed 10 mg L–1. A laboratory column study was conducted to investigate the ability of a wood chip bioreactor to promote denitrification under mean water flow rates of 2.9, 6.6, 8.7 and 13.6 cm d–1 which are representative of flows entering subsurface drainage tiles. ...

  • Reducing Odor and VOC Emissions

    The Montgomery County Regional Composting Facility (MCRCF) in Silver Spring, Maryland is designed to process 400 wet tons/day of lime amended biosolids from the Blue Plains Wastewater Treatment Plant (WWTP) in Washington, D.C. Recently, political pressures forced operations to cease at the MCRCF. Although the aerated static pile composting plant’s fate has not been completely decided, its owner, ...

  • `Making good earth better` goal of waste-to-resource firm

    “One man’s trash is another man’s treasure.” Nowhere is that more true than in northern Ohio, where a long-established waste-to-resource company is turning everything from demolition and construction waste and sewage sludge into products that homeowners and businesses can use to spruce up their properties. “I can’t believe what we do,” enthuses Diane Kurtzman, a spokesperson for Kurtz Bros. Inc., ...

  • Biodegradation of methane and halocarbons in simulated landfill biocover systems containing compost materials

    The attenuation potential of methane (CH4) and of selected volatile organic compounds (VOCs) was compared in four types of compost materials using dynamic flow column experiments over a period of 255 d. Garden waste compost mixed with wood chips showed the highest steady-state CH4 oxidation rate (161 g m–2 d–1), followed by a commercial compost product Supermuld (110 g m–2 d–1). In the column ...

  • Landfill grinding system

    A landfill needed a way to reduce their waste stream volume, increase the life of their landfill, and recover a recyclable, marketable product. Wood and yard waste material comprise up to 20% of their entire waste stream volume. Processing and recycling this material will extend the life of the landfill by 20 years. They chose WSM's Model 4864BH Horizontal Hogging System with a customized feed ...

  • Volatile organic compounds emitted from hardwood drying as a function of processing parameters

    During the drying of wood, volatile organic compounds are emitted. These emissions contribute, in the presence of nitrogen oxides and sunlight, to the formation of ground level ozone and other harmful photo-oxidants. Emissions of volatile organic compounds from the drying of birch sawdust in a spouted bed were analyzed with a flame ionization detector and with a gas chromatograph-mass ...

  • The simple, effective and economical treatment of odourous emissions

    The odours from an anaerobic digester and a waste handling depot were fed to two large biofilters with wood chip packing. The seeding of the biofilters was carried out using a microbial product, BFL Odour Clean. For the initial seeding of the biofilter with microbial cultures a manual method of application was used. Careful application of the product to the entire filter bed is key to the success ...
