  1. 1. Material properties and full-scale rain exposure of lime-hemp concrete walls : measurements and simulations

    Författare :Paulien De Bruijn; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Lime-hemp concrete (LHC) is a building material consisting of a lime-based binder combined with hemp shiv that is suitable for various building applications. This thesis aimed to elucidate the possibilities for using LHC for exterior walls in a cold, wet climate through investigating mechanical, thermal and moisture-related properties of the material.

  3. 2. Novel uses of bio-polymers in composites : from chemistry to processing of materials and food

    Författare :Faraz Muneer; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Plant bio-polymers obtained as industrial side-streams (wheat gluten and potato proteins) and specifically designed potato starch and hemp fibres were used to produce composite materials. Fractionated pea protein and pea dietary fibres were used to make pasta-like sheets for production of healthy food. LÄS MER

  4. 3. Tuning the long-term properties to control biodegradation by surface modifications of agricultural fibres in biocomposites

    Författare :Thorsak Kittikorn; Monica Ek; Ferruccio Doghieri; KTH; []
    Nyckelord :agricultural fibres; biocomposites; renewable polymers; PP; PLA; PHBV; surface modifications; water uptake; microbial growth; biodegradation;

    Sammanfattning : Sustainable polymeric materials put emphasis on mastering the whole life-cycle of polymeric materials. This includes the choice of raw materials, selection of synthesis and processing, environmental impact during long-term use followed by detailed knowledge about recycling and waste management.

  5. 4. Modification of fluff pulp fibres: Cross-linking and alkali extraction

    Författare :Kristoffer Lund; Chalmers tekniska högskola; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; fibre network; dry defibration; network strength; fluff pulp; Absorption; cross-linking; alkali extraction; kraft pulp;

    Sammanfattning : Fluff pulp has been one of the key components of hygienic products, such as diapers, for many years. Fluff pulp is dry defibrated and air-laid into the absorption core of diapers. The introduction of superabsorbent polymers (SAPs) in the 1980s decreased the dependence on fluff pulp, as the SAPs became the main absorbing material. LÄS MER

  7. 5. Anaerobic Digestion of Wastewaters from Pulp and Paper Mills : A Substantial Source for Biomethane Production in Sweden

    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
