  1. 1. Forest-Fuel Systems : Comparative Analyses in a Life Cycle Perspective

    Författare :Lisa Näslund Eriksson; Leif Gustavsson; Antti Asikainen; Mittuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; forest fuels; recovery systems; transportation; cost; primary energy use; CO2 emission; forest-fuel potential; life cycle perspective; Environmental engineering; Miljöteknik;

    Sammanfattning : Forest fuels can be recovered, stored and handled in several ways and these different ways have different implications for CO2 emissions. In this thesis, comparative analyses were made on different forest-fuel systems. The analyses focused on the recovery and transport systems. LÄS MER

  3. 2. Improving the efficiency of forest fuel supply chains

    Författare :Anders Eriksson; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Forest biomass has gained much interest as a resource for renewable energy production world-wide. In Sweden, easily accessible secondary forest fuels, such as by-products from the conventional forest industry, are today already fully utilised. LÄS MER

  4. 3. A Systems View of Advancements in Biomass Supply Chains

    Författare :Johanna Enström; Aron Larsson; Leif Olsson; Lars Eliasson; Anders Eriksson; Daniel Nilsson; Mittuniversitetet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Forestry logistics; Supply Chain Management; Discrete Event Simulation; Forest fuel;

    Sammanfattning : Forest fuel is an important source of energy with potential for increased use in the Nordic countries. Profitable forest operations are dependent on logistics as the forest is a natural resource with varying conditions over widespread areas. LÄS MER

  5. 4. Energy use and environmental impact of roundwood and forest fuel production in Sweden

    Författare :Eva-Lotta Lindholm; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : The increasing awareness of climate change issues, unstable fossil fuel prices and concerns about energy security are leading to a rising demand for forest products. If meeting this demand involves increased harvesting it is essential to employ efficient systems that allow sustainable forest management. LÄS MER

  7. 5. The European forest trade model : EU policy and the impact on forest raw material use

    Författare :Anna Mansikkasalo; Luleå tekniska universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Economics; Nationalekonomi;

    Sammanfattning : The main purpose of this study is to develop a numerical simulation model of the European trade in forest fuels and analyse the possible trade levels for forest fuels in Europe following the implementation of EU energy policy. The White Paper and the RES-E Directive have been designed partly to support an increased use of forest fuels as sources for energy generation. LÄS MER
