  1. 31. Greenhouse gas fluxes between drained forested peatlands and the atmosphere - influence of nutrient status and wood ash fertilization

    Författare :Maria Ernfors; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; greenhouse gases; peatlands wood; ash; nutrient status;

    Sammanfattning : The management of peatlands for wood production involves drainage and, sometimes, fertilization with, for example, wood ash. The effects of these measures on greenhouse gas fluxes, in relation to the ... LÄS MER

  3. 32. 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

  4. 33. Spatial economic modelling of greenhouse gas abatement on agricultural land

    Författare :Ida Nordin; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Sammanfattning : This thesis investigates how agricultural land can be used for cost-effective abatement of greenhouse gas (GHG) emissions. The impacts of spatial relationships and characteristics of land on the costs of producing biofuel for the purpose of emissions abatement, and on global emissions caused by agricultural policies, are evaluated using spatial economic models.

  5. 34. 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

  7. 35. Evaluating the utilisation of industrial excess heat from an energy systems perspective

    Författare :Igor Cruz; Magnus Wallén; Mats Söderström; Maria Johansson; Danica Djuric Ilic; Johanna Mossberg; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industrial excess heat; Waste heat; Heat recovery; Greenhouse gas emissions;

    Sammanfattning : Sweden aims to achieve climate neutrality by 2045. The need to immediately reduce greenhouse gas emissions in order to achieve climate targets affects industry directly. The pulp and paper sector is responsible for more than 50% of industrial energy use in Sweden. LÄS MER
