    Kandidat-uppsats, Jönköping University/JTH, Byggnadsteknik och belysningsvetenskap

    Författare :Sara Carlehed; Saga Jostelius; [2023]
    Nyckelord :Koldioxidekvivalenter; limträ; industribyggnad; stommaterial; LCA; stål; trä; hållbarhet; klimatpåverkan; innovation; attityder;

    Sammanfattning : Purpose – the climate issue is one of the most important political issues, both in Sweden and globally. Achieving the climate goals of the Paris Agreement and the Agenda 2030 sustainability goals requires efforts to slow down global warming. LÄS MER

  3. 17. Reprocessing and Characterization of Polybenzimidazole for High-Temperature Polymer Electrolyte Membrane Fuel Cells

    Master-uppsats, Lunds universitet/Centrum för analys och syntes

    Författare :Douglas Björkengren; [2023]
    Nyckelord :polymer electrolyte membrane fuel cells; PEMFC; HTPEMFC; polymer technology; polymer characterization; reprocessing; recycling; polybenzimidazole; PBI; Technology and Engineering;

    Sammanfattning : A reprocessing method of poly(2,2’-(m-phenylene)-5,5’-bibenzimidazole) (PBI) membranes recovered from the production line of High-Temperature Polymer Electrolyte Membrane Fuel Cells (HT-PEMFC) at Blue World Technologies (BWT) has been developed in order to reduce material loss in the production. Redissolution of scrap PBI membranes in poly(phosphoric acid) (PPA) and phosphoric acid (PA) was successful and the subsequent washing procedure produced PBI that could be redissolved in N,N-dimethyl acetamide (DMAc) and suitable for solution casting of new membranes.

  4. 18. Potential of local producing bioenergy/biogas from waste in the municipality of Ragunda

    Kandidat-uppsats, Mittuniversitetet/Institutionen för naturvetenskap, design och hållbar utveckling (2023-)

    Författare :Tomás Hayes; [2023]
    Nyckelord :Bioenergy; Biogas; Biomethane; Global Warming Potential; Rural development;

    Sammanfattning : Population growth, climate change and increased global energy demand has led to the search for environment friendly energy sources. Ragunda Municipality’s major producers of Greenhouse Gas (GHG) emissions are transport, agriculture, and work machines. LÄS MER

  5. 19. A coupling method using CFD, radiative models and a surface model to simulate the micro-climate

    Master-uppsats, KTH/Teknisk mekanik

    Författare :Joseph Vernier; [2023]
    Nyckelord :Computational Fluid Dynamics; Fluid Mechanics; Numerics; Micro-climate modeling; Radiation; Crop modeling; Photovoltaic panels;

    Sammanfattning : The increasing demand for energy, depletion of fossil fuels, rising global warming, and greenhouse gas emissions have stimulated the need for widespread development and adoption of renewable energy sources (RES) worldwide. Among these sources, solar energy has emerged as a major contender to meet the growing demand. LÄS MER

  7. 20. Leisure, well-being, and sustainable lifestyles : A study to explore relationships between leisure activities and global warming potential in Sweden.

    Magister-uppsats, Högskolan i Gävle/Avdelningen för byggnadsteknik, energisystem och miljövetenskap

    Författare :Anna Högberg; Beatrice Guardini; [2023]
    Nyckelord :Well-being; sustainable lifestyle; leisure activities; global warming potential;

    Sammanfattning : Studies show that leisure activities can contribute significantly to people’s well-being. Still, theycan also impact the environment in several ways as they contribute to greenhouse gas emissionsrelated to different factors. LÄS MER
