  1. 1. Climate impacts due to albedo change in LCA of agricultural systems

    Author : Petra Sieber; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Agricultural systems for production of food, energy and materials are a major driver of climate change, due to land use and greenhouse gas (GHG) emissions along the supply chain. Crop cultivation also affects the climate by changing land surface albedo, i.e. the fraction of solar radiation reflected back from the ground. READ MORE

  2. 2. Temporal climate impacts of using willow and logging residues for district heating in Sweden

    Author : Torun Hammar; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Using bioenergy to replace fossil fuels has been adopted as a climate mitigation measure, since less greenhouse gases are expected to be released into the atmosphere. In Sweden, the share of bioenergy is relative high (about 23% of total consumption including peat), with a relatively large proportion originating from domestically produced forest biomass.

  3. 3. Effectiveness and Evaluation of Wood Protection against Biological Deterioration Caused by Filamentous Fungi

    Author : Olena Myronycheva; Olov Karlsson; Lone Ross; Luleå tekniska universitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Träteknik; Wood Science and Engineering;

    Abstract : Developing a holistic understanding of the biological deterioration of wooden material by fungi in the laboratory and outdoor conditions requires the development of new assessment procedures and tools that allow describing the process with maximum precision and accuracy. Environmental biodeterioration is a complex process including a combination of physical, chemical and biological changes, with many uncertainties limiting the predictability and effectiveness of selected preservatives after laboratory tests.

  4. 4. Chemical and physical incorporation of bio-molecules into wood materials for energy storage

    Author : Meysam Nazari; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : The environmental impact of fossil-based materials in the building industry and significant energy consumption in residential buildings have urged new research areas in using bio-based, renewable and sustainable materials for production of energy smart bio-based envelopes for building applications. This can be achieved by incorporation of bio-based phase change materials (BPCMs) in wood materials for energy storage in residential buildings. READ MORE

  5. 5. Ash transformation during thermochemical conversion of agricultural biomass in entrained flow conditions

    Author : Samarthkumar Pachchigar; Marcus Öhman; Markus Broström; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Agricultural biomass; entrained flow conditions; combustion; ash transformation; Si recovery; P recovery; Energiteknik; Energy Engineering;

    Abstract : Agricultural biomass is considered a prospective renewable feedstock in the energy conversion units. Despite its widespread availability, agricultural biomass is often underutilized in the thermochemical processes due to its high ash content. READ MORE
