  • 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 ...

  • 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. ...

  • Ramial Chipped Wood: the Clue to a Sustainable Fertile Soil

    Close to forty percent of the world's agricultural land is seriously degraded, which could undermine the long-term productive capacity of those soils. Plus, the economic and social effects of agricultural land degradation have been much more significant in developing countries than in industrialized countries. However, they are the regions where the greatest growth in food production will be ...

  • 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 ...

  • Making environmentally friendly fuel from wood chips - Case Study

    The RUF briquetting press earns the Ortinger company additional profits During the production of round bars or rods for flags, skewers and many more products made from wooden planks, lots of wood chips are accumulated.

  • Mesquite wood chips (Prosopis) as filter media in a biofilter system for municipal wastewater treatment

    The biofiltration system over organic bed (BFOB) uses organic filter material (OFM) to treat municipal wastewater (MWW). This study evaluated the performance of a BFOB system employing mesquite wood chips (Prosopis) as OFM. It also evaluated the effect of hydraulic loading rates (HLRs) in order to achieve the operational parameters required to remove organic matter, suspended material, and ...

  • Wood waste product

    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 ...

  • Wood Chipper-Drum Type

    A wood chipper is a machine used for crushing wood, generally tree logs or branches, into smaller woodchips. They are often portable, being mounted on wheels on frame suitable for various working environment.

  • A pannell of chipping experts perseverance, service and dependability are hallmarks for Oklahoma-based Pannell Chipping, Inc.

    While logging and landclearing professionals as a whole have often been broadly - and inaccurately - portrayed as anti-conservators of the land, one segment of that profession, chipping companies, have suffered disproportionately. Presented as insensitive to the benefits of good forestry, they have had to literally fight to prove that they are indeed good stewards of the land, providing a ...
