  2. 1. System studies of forest-based biomass gasification

    Author : Elisabeth Wetterlund; Mats Söderström; Magnus Karlsson; Simon Harvey; Pål Börjesson; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biomass gasification; second-generation biofuels; global CO2 emissions; energy system optimisation;

    Abstract : Bioenergy will play an important role in reaching the EU targets for renewable energy. Sweden, with abundant forest resources and a well-established forest industry, has a key position regarding modern biomass use. READ MORE

  4. 2. Integrated sewage sludge treatment scenarios – techno-economic analysis on energy and phosphorus recovery

    Author : Marzieh Bagheri; Elisabeth Wetterlund; Marcus Öhman; Lale Andreas; Roozbeh Feiz; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sewage sludge management; techno-economic analysis; phosphorus recovery; thermochemical treatment; Energy Engineering; Energiteknik;

    Abstract : Sewage sludge is a by-product of wastewater treatment that simultaneously gathers contaminants, valuable organic matter, and nutrients. The treatment of the increasing amount of sewage sludge is important from both pollution prevention and resource recovery perspectives as i) large shares of mineral phosphorus, listed as a critical raw material, terminate in the sewage sludge, and ii) energy recovery from sewage sludge can cover the energy-intensive demand of the treatment process.

  6. 4. Sustainable Sewage Sludge Management : Addressing Multidisciplinary Challenges

    Author : Torben Bauer; Lale Andreas; Elisabeth Wetterlund; Anders Lagerkvist; Anders Damgaard; Christina Dornack; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Avfallsteknik; Waste Science and Technology;

    Abstract : This PhD thesis focuses on multidisciplinary challenges in sewage sludge management and how they can be addressed to increase sustainability. Sewage sludge is the residual from wastewater treatment. It contains both resources and contaminants making its management challenging. READ MORE

  7. 5. Opportunities to broaden biomass feedstocks in thermochemical conversion technologies

    Author : Lara Carvalho; Joakim Lundgren; Elisabeth Wetterlund; Erik Furusjö; Andrea Ramírez Ramírez; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Non-woody biomass; Combustion; Gasification; Biofuels; Techno-economic analysis; Energiteknik; Energy Engineering;

    Abstract : Global environmental concerns are motivating a growing interest in broadening the biomass feedstock base in several energy sectors, including (i) the domestic heating sector, presently dominated by stem wood combustion, and (ii) biofuel production, presently dominated by edible crops. The objective of this thesis is to investigate new opportunities to broaden the biomass feedstock in thermochemical conversion technologies. READ MORE
