  1. 1. Conditions and Constraints for Waste Management. Collection, Characterisation and Producer Responsibility in Sweden

    Detta är en avhandling från Chalmers University of Technology

    Författare :Cecilia Mattsson Petersen; Högskolan Dalarna.; Chalmers tekniska högskola.; Chalmers University of Technology.; [2004]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; collection; household waste; landfill ban; producer responsibility; source separation; waste characterisation; waste component analysis; waste management; Miljöteknik; Environmental engineering;

    Sammanfattning : Waste management has changed from being mainly a question of transporting out of sight to being an issue entwined in all parts of society, from product planning to the private domestic sphere. This has imposed new conditions and constraints for waste management, the description of which is the objective of this thesis. LÄS MER

  2. 2. Combined solar and pellet heating systems Study of energy use and CO-emissions

    Detta är en avhandling från Institutionen för Samhällsteknik

    Författare :Frank Fiedler; Mälardalens högskola.; Högskolan Dalarna.; [2006]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TECHNOLOGY Other technology Environmental engineering; TEKNIKVETENSKAP Övriga teknikvetenskaper Miljöteknik; Energi- och miljöteknik; Solar heating; pellet heating; Pellet and solar heating systems; CO-emissioins;

    Sammanfattning : In this study 4 solar and pellet heating systems have been studied with the help of annual dynamic simulations. Two of the systems comprised a pellet stove and two systems were solar combisystems; one with a store integrated pellet burner, the other with a separate pellet boiler. LÄS MER

  3. 3. Platinum Group Elements in Birds of Prey

    Detta är en avhandling från Chalmers University of Technology

    Författare :Kristine H. Ek; Chalmers tekniska högskola.; Chalmers University of Technology.; [2005]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Miljöteknik; Environmental engineering; palladium; platinum; rhodium; ICP-MS; laser ablation; bird of prey; airborne particles;

    Sammanfattning : The environmental concentrations of Pd, Pt and Rh (three of the platinum group elements, PGE) have increased since the introduction of exhaust catalysts on automobiles. A limited understanding of the environmental distribution and effects of the platinum group elements has raised concern over their potential biological availability. LÄS MER

  4. 4. Biological Pre-filtration and Surface Water Treatment - Microbial barrier function and removal of natural inorganic and organic compounds

    Detta är en avhandling från Chalmers University of Technology

    Författare :Gerald Heinicke; Chalmers tekniska högskola.; Chalmers University of Technology.; [2005]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Samhällsbyggnadsteknik och arkitektur; Civil engineering and architecture; Miljöteknik; Environmental engineering;

    Sammanfattning : Waterworks in Sweden that apply conventional chemical surface water treatment are facing a number of challenges, including changes in raw water quality and demands for improved particle removal. The chief objective of this work was to evaluate biological pre-filtration for typical Swedish surface water, regarding the removal of natural organic matter, particles, iron and manganese, and taste and odour compounds.

  5. 5. Anaerobic digestion of horse manure renewable energy and plant nutrients in a systems perspective

    Detta är en avhandling från Gävle : Gävle University Press

    Författare :Åsa Hadin; Högskolan i Gävle.; [2016]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Horse manure; horse keeping; anaerobic digestion; nutrient recycling; systems perspective; bedding; methane potential; feedstock; biogas; biofertilizer; Hästgödsel; hästhållning; rötning; näringsåterföring; systemperspektiv; strömaterial; metanpotential; biogassubstrat; biogas; biogödsel;

    Sammanfattning : In horse keeping horse manure is produced, which can be utilized as a fertilizer or considered a waste. Horse manure constitutes a resource in terms of both plant nutrients and energy. In addition energy policies and objectives aim at replacing fossil fuels with renewable energy sources. LÄS MER
