  1. 16. Nitrogen flow in Scania : substance flow analysis on a regional level

    Master-uppsats, SLU/Dept. of Energy and Technology

    Författare :Johanna Hellstrand; [2015]
    Nyckelord :substance flow analysis; fertilizer; sewage sludge; wastewater; urine separation; manure;

    Sammanfattning : In this thesis, the flows of reactive nitrogen (Nr) in Scania were investigated and quantified. The thesis was also intended to form a basis for comparison between the urban nitrogen flow and other flows of nitrogen within Scania. The management of nitrogen in society has disturbed the natural nitrogen cycle. LÄS MER

  3. 17. Bioenergy production from beach-cast macro algae : The West Coast of Sweden

    Magister-uppsats, Högskolan i Halmstad/Akademin för ekonomi, teknik och naturvetenskap

    Författare :Meaza Tadesse Yohannes; [2015]
    Nyckelord :eutrophication; beach cast macro algae; cadmium; cadmium removal; energy extraction; anaerobic digestion; combustion; incineration; energy balance analysis;

    Sammanfattning : Excessive algae growth/ bloom has become a commonly observed phenomenon in many water bodies globally due to eutrophication. This phenomenon has also been observed in the Baltic Sea which create nuisance in many Baltic coastal communities when the macro algae of different species is washed ashore by wind and wave, which is known as “beach cast algae”.

    Sammanfattning : Energy costs and environmental standards encouraged cement manufacturers worldwide to evaluate to what extent conventional fuels (Furnace oil, Coal and Petcock) can be replaced by alternative fuels in cement production, i.e. LÄS MER

  7. 20. Combustion of sludge in Fortum’s plants with possible phosphorus recycling

    Master-uppsats, KTH/Kraft- och värmeteknologi

    Författare :Victor Hoffman; Anton Marmsjö; [2014]
    Nyckelord :Sludge combustion; phosphorus;

    Sammanfattning : The management of waste is by all means a great challenge to any society. In Sweden, the past decades has seen legislation progressing in congruence with concerns over environmental stress from inefficient waste management. The legislative changes aim primarily to promote waste reduction and better waste utilization. LÄS MER
