  2. 1. Bioenergy from Swedish forests : A Study of extraction methods, quality and effects for forest owners

    Author : Daniel Nilsson; Johan Bergh; Peter Lerman; Gudmund Vollbrecht; Nasko Terziew; Linnéuniversitetet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; logging residues; forest fuels; moisture content; needles; nutrients; moisture content measurements; Norway spruce; dry-stacking; fresh-stacking; Forestry and Wood Technology; Skog och träteknik;

    Abstract : The forest constitutes a very important element of renewable natural resources and makes a significant contribution to the Swedish bioeconomy. Biofuels are Sweden’s largest source of energy; of all the energy we use, 32% comes from biofuels, and of this approximately 85% comes from the forest and the forestry sector. READ MORE

  4. 2. On the contribution of forest bioenergy to climate change mitigation

    Author : Olivia Cintas Sanchez; Chalmers tekniska högskola; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Forest bioenergy; forest management; climate change; energy systems.; GHG balances; forest supply; carbon budget;

    Abstract : Greenhouse gas (GHG) emissions have to be drastically reduced to keep global warming below 2 degrees. Bioenergy can play a role in climate change mitigation by substituting for fossil fuels. READ MORE

  5. 3. Direct and indirect pressures of climate change on nutrient and carbon cycling in northern forest ecosystems : Dynamic modelling for policy support

    Author : Klas Lucander; BECC: Biodiversity and Ecosystem services in a Changing Climate; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Forest; boreal ecosystems; Forest biogeochemistry; Forest bioenergy; Boreal coniferous forest; base cations; Biogeochemical cycles; Dynamic Modelling; Carbon cycle; nitrogen cycle; decision support; policy-making; Weathering; Forestry; Land use change;

    Abstract : Northern forest ecosystems play an important role in mitigating climate change by sequestrating carbon (C), while additionally providing and regulating other ecosystem services. A majority of the Swedish environmental quality objects (EQOs) that guide Swedish environmental policy and management are associated with the forest, and they have proven difficult to achieve.

  6. 4. Extraction of logging residues for bioenergy : effects of operational methods on fuel quality and biomass losses in the forest

    Author : Bengt Nilsson; Johan Bergh; Gudmund Vollbrecht; Rolf Björheden; Linnéuniversitetet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Forest fuel; Storage; Fraction composition; Needles; Defoliation; Moisture content; Nutrients; Nitrogen; Norway spruce; Picea abies; Skogsbränsle; Lagring; Fraktionsfördelning; Barr; Avbarrning; Fukthalt; Näringsämnen; Kväve; Gran; Picea abies; Forestry and Wood Technology; Skog och träteknik;

    Abstract : Wood products play a key role in the transformation to a more sustainable society based on renewable bio-based resources, together with the positive effects on climate mitigation by replacing fossil fuels. However, to increase the use of forest fuel in practice it is important to understand the effects of handling and storage on its quality and removal of nutrients from the forest. READ MORE

  7. 5. Land-Use and Climate Effects of Bioenergy: Carbon balances of Swedish forest bioenergy systems – and – Geospatial biomass supply-and-demand matching for Europe

    Author : Olivia Cintas Sanchez; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; GIS; EU; bioenergy; Sweden; agriculture; residues; Forestry; climate change; GHG balances;

    Abstract : In order to keep global warming below 2 degrees Celsius, greenhouse gas emissions have to be drastically reduced. Bioenergy can play a role in climate change mitigation by substituting for energy from fossil fuels; however, biomass is a limited resource associated with emissions from land use and land-use change.
