  2. 11. Managing timber procurement in Nordic purchasing sawmills

    Author : Klara Helstad; Rolf Björheden; Lars-Olof Rask; Anders Baudin; Lauri Sikanen; Växjö universitet; []
    Keywords : Procurement management; Sawmill industry; Supply uncertainties; Buyer-supplier relationships; Bucking; Contractual forms; Strategy; Case Studies; FORESTRY; AGRICULTURAL SCIENCES and LANDSCAPE PLANNING; SKOGS- och JORDBRUKSVETENSKAP samt LANDSKAPSPLANERING;

    Abstract : Procurement of sawlogs to purchasing sawmills represents a basic strategic business process. The properties of inbound sawlogs are decisive for the output of sawn products and the cost of raw material contributes substantially to the cost of the final product. READ MORE

  4. 12. Automatic analysis of log end face images in the sawmill industry

    Author : Kristin Norell; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : At present grading of sawlogs in a sawmill relies on visual inspection wherein a human expert grades a log every few seconds as it passes on a conveyor belt. This tedious and difficult work is prone to substantial inter- and intra-grader variability. READ MORE

  5. 13. Chlorinated organic pollutants in soil and groundwater at chlorophenol-contaminated sawmill sites

    Author : Ylva Persson; Mats Tysklind; Lars Öberg; Staffan Lundstedt; Jaana Koistinen; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; contaminated soil; hydrophobic organic contaminant; chlorinated phenoxyphenol; chlorinated diphenyl ether; chlorinated dibenzofuran; chlorinated dibenzo-p-dioxin; preservation; mobility; colloid; dissolved organic matter; particulate organic matter; groundwater; equilibrium column test; chlorophenol; Environmental chemistry; Miljökemi;

    Abstract : Mixtures of chlorinated organic pollutants can be found in the soils at chlorophenol-contaminated sawmill, including (inter alia) polychlorinated phenols (CPs), phenoxyphenols (PCPPs), diphenyl ethers (PCDEs), dibenzofurans (PCDFs) and dioxins (PCDDs). These hydrophobic compounds have low water solubility and hence low mobility as truly dissolved compounds. READ MORE

  6. 14. Design, development and implementation of a mechatronic log traceability system

    Author : Björn Möller; Jan Wikander; Kalevi Hyyppä; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering mechanics; Teknisk mekanik; Construction engineering; Konstruktionsteknik;

    Abstract : This thesis concerns a mechatronic system, designed and developed for the forest industry, to trace logs from forest to sawmill. The research is a key part of a large research project launched by the EU in 2006 called the Indisputable Key project. READ MORE

  7. 15. Total quality management in sawmills

    Author : Carl-Gustav Lundahl; Arto Usenius; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Träteknik; Wood Technology;

    Abstract : This work was initiated in order to show the potential for Swedish sawmills to achieve higher productivity by implementation of improved process control tools in breakdown and production flows. An effective and profitable sawmill must utilize its raw material and the skill of its staff effectively. READ MORE
