    Abstract : The climate change on our planet is an issue of great concern. The dignity of this issue was confirmed by the award of the international panel of climate change (IPCC) the Nobel peace prize. This problem arises from the way that we live our lives, how we produce energy, materials and chemicals from a fossil source. READ MORE

  2. 2. Lignin polysaccharide networks in softwood and chemical pulps characterisation, structure and reactivity

    Abstract : The chemical interactions between the main wood components i.e., cellulose, hemicelluloses and lignin are of fundamental importance for understanding the chemical aspects of wood formation and its reactivity during fibre processing e.g during chemical pulping of wood. READ MORE

  3. 3. A biomimicking approach for hemicellulose processing

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Petri Oinonen; KTH.; [2014]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mechanical pulping; Hemicellulose; Cross-linking; Lignin-carbohydrate-complex; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Abstract : Lignocellulose can become the best opportunity for the society to reduce its dependency on the harmful petroleum based products as well as to produce clean energy. In each part of the production cycle, biomass based products have a better environmental profiles than their petroleum based counterparts. READ MORE

  4. 4. Lignocellulose Degradation by Soil Micro-organisms

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Ran Bi; KTH.; KTH.; [2016]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Lignocellulosic biomass is a sustainable resource with abundant reserves. Compared to petroleum ‐ based products, the biomass ‐ derived polymers and chemicals give better environmental profiles. A lot of research interest is focused on understanding the lignocellulose structures. READ MORE

  5. 5. Self-bonding of beech veneers

    University dissertation from Luleå tekniska universitet

    Author : Carmen Cristescu; Luleå tekniska universitet.; [2015]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Träteknik; Wood Technology;

    Abstract : This thesis presents studies on the self-bonding of veneers, and investigations into the properties of boards obtained by hot-pressing beech veneers without adhesives. The raw material is pressed at temperatures from 200 to 250ºC, at pressures from 4 to 6 MPa and pressing times from 240 to 360 s. READ MORE
