  1. 21. Greenhouse gas emissions from food and garden waste composting : effects of Management and Process Conditions

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

    Sammanfattning : Composting is a robust waste treatment technology. Use of finished compost enables plant nutrient recycling, carbon sequestration, soil structure improvement and mineral fertiliser replacement. However, composting also emits greenhouse gases (GHG) such as methane (CH₄) and nitrous oxide (N₂O) with high global warming potential (GWP). LÄS MER

  3. 22. Land use effects on nitrous oxide emission from drained organic soils

    Författare :Per Weslien; Göteborgs universitet; []
    Nyckelord :Greenhouse gas emissions; N2O; Peat soils; Land use;

    Sammanfattning : Since industrialisation, the atmospheric concentration of greenhouse gases (GHG) has increased significantly. The most important anthropogenic GHGs are carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O). N2O is of major concern for two reasons; i) it is a potent GHG responsible for 6. LÄS MER

  4. 23. Regional Energy Systems with Retrofitted Combined Heat and Power (CHP) Plants

    Författare :Song Han; Yan Jinyue; Thorin Eva; Deng Shiming; Mälardalens högskola; []
    Nyckelord :Combined heat and power; Waste-to-Energy WtE ; Regional energy system; Greenhouse gases GHG ; Retrofitting; Optimization; Kraftvärme; Avfall-till-Energi; Regionala Energisystem; Växthusgaser; Uppgradering; Optimering.; Energy- and Environmental Engineering; energi- och miljöteknik;

    Sammanfattning : Fossil fuel depletion, economic development, urban expansion and climate change present tough challenges to municipal- and regional-scale energy systems. Regional energy system planning, including waste treatment, renewable energy supply, energy efficiency, and climate change, are considered essential to meet these challenges and move toward a sustainable society.

    Nyckelord :Agricultural by-products; Straw; Bioethanol; Transport system; Greenhouse gases GHG ; Polygeneration system; Combined Heat and Power CHP ; Mixed Integer Programming MIP .; Energy- and Environmental Engineering; energi- och miljöteknik;

    Sammanfattning : Road traffic dominates in domestic Swedish transportation and is highly dependent on fossil fuels, petrol and diesel. Currently, the use of renewable fuels in transportation accounts for less than 6% of the total energy use in transport. LÄS MER

  7. 25. Studies in environmental economics : numerical analysis of greenhouse gas policies

    Författare :Charlotte Nilsson; Handelshögskolan i Stockholm; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Sammanfattning : This thesis consists of four essays within the field of environmental economics. Computable General Equilibrium models have been used to assess the economic consequences of greenhouse gas policies. The focus is mainly on the Swedish economy, but the EU economies and the global economies are also analyzed in one essay each. LÄS MER
