    Författare :Madeleine Larsson; Anna Karlsson; Bo H. Svensson; David Bastviken; Thomas Welander; Linköpings universitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Anaerobic digestion; wastewater treatment; biogas; methane; pulp and paper mill wastewater; pulp bleaching; wood raw material; Anaerob nedbrytning; vattenrening; biogas; metan; avloppsvatten från pappers- och massaindustrin; massablekning; träråvara;

    Sammanfattning : The Swedish pulp and paper industry is the third largest exporter of pulp and paper products worldwide. It is a highly energy-demanding and water-utilising industry, which generates large volumes of wastewater rich in organic material. LÄS MER

  3. 2. Hemicellulose-based wood adhesives

    Författare :Tijana Todorovic; Eva Malmström; Linda Fogelström; Francisco Vilaplana; Magdalena Sterley; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Sammanfattning : The increasing sustainability concern encourages the society to use sustainable resources. In the wood industry the main component is from a renewable resource, but others are not. One of the fossil-based components is the adhesive. LÄS MER

  4. 3. Wood Hydrolysate for Renewable Products

    Författare :Yingzhi Zhu Ryberg; Ulrica Edlund; Ann-Christine Albertsson; Ann Cornell; Louise Staffas; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; wood hydrolysate; hemicellulose; oxygen permeability; PALS; film; coating; CMC; chitosan; HSP; Polymer chemistry; Polymerkemi;

    Sammanfattning : Renewable biomass has been used by mankind for a long time for different purposes, from simply food to industrial products. Among a large family of polysaccharides, hemicellulose is non-edible but has shown a potential in many industrial fields such as medicine, agriculture and packaging. LÄS MER

  5. 4. Biosynthesis, interactions, and structure of native lignin

    Författare :Ioanna Sapouna; Lauren S. McKee; Francisco Vilaplana; Claudia Crestini; KTH; []

    Sammanfattning : Wood biomass is an important resource in the development ofstrategies towards replacement of fossil-based materials. Woodcomprises cellulose, hemicelluloses and lignin, in amounts thatvary between species. LÄS MER

  7. 5. Extraction of Lignin from Kraft Cooking Liquor by Ultrafiltration

    Författare :Ola Wallberg; Avdelningen för kemiteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; lignin; Chemical technology and engineering; cooking liquor; kraft black liquor; Kemiteknik och kemisk teknologi; Ultrafiltration;

    Sammanfattning : Lignin is a potential biofuel which can be extracted from kraft cooking liquor. Lignin can also prove valuable as a speciality chemical. By extracting lignin potential economical revenue can be gained by pulp mills, as well as technical benefits such as easier delignification and bleaching. LÄS MER
