  1. 1. Evaluating the potential of circular food waste management : A focus on insect feed utilization

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Jenny Eliasson; [2023]
    Nyckelord :Circular economy; Circular Business Models; BSF; Mealworm; Barriers; Drivers; Cirkulär ekonomi; Circkulära affärsmodeller; Soldatfluga; Mjölmask; Barriärer; Drivkrafter;

    Sammanfattning : Approximately a third of all food produced globally is thrown away, causing both unnecessary environmental impact and unnecessary costs for producers and consumers. Food waste occurs in all steps in the supply chain, from primary production to retail stores, restaurants, and households. LÄS MER

  3. 2. Finding ways to develop a sustainable bioeconomy: The case of industrial cassava in Colombia : Environmental impact and food security insights from a combined life cycle assessment and interview study

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Isabel Nilsson Alarcón; [2023]
    Nyckelord :industrial cassava; food security; land use; climate change; biodiversity loss; sustainable bioeconomy; Life Cycle Assessment LCA ; Colombia; industriell kassava; tryggad livsmedelsförsörjning; markanvändning; klimatförändring; minskad biodiversitet; hållbar bioekonomi; livscykelanalys LCA ; Colombia;

    Sammanfattning : Cassava has been identified as a potential key crop for a sustainable bioeconomy in Colombia.However, the bioeconomy is not inherently sustainable, and neither is producing cassava,which makes research on it crucial. Increasing biomass circularity could be key for increasingthe cassava industry’s sustainability performance. LÄS MER

  4. 3. Pilot scale partial denitratation coupled anammox: an evaluation

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Tobias Ellingsen; [2022]
    Nyckelord :mainstream anammox; partial denitratation anammox; partial denitrification anammox; PDA; nitrite inhibition; anammox; water and environmental engineering; Technology and Engineering;

    Sammanfattning : På avloppsreningsverk (ARV) som tillämpar kväverening är den vanligaste tekniken nitrifikation följt av denitrifikation. Denna process kräver omfattande luftning, vilket både är elintensivt och minskar mängden biogas som kan utvinnas. LÄS MER

  5. 4. Climate impact of bioH2 production from biogas using CO2 mineralization for carbon capture and storage

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

    Författare :Hera Harðardóttir; [2022]
    Nyckelord :carbon capture and storage; carbon dioxide mineralization; biohydrogen production; global warming potential; greenhouse gases;

    Sammanfattning : Carbon dioxide (CO2) concentrations in the atmosphere are increasing and are now higher than they have ever been, mostly because of CO2 released from burning fossil fuels for energy. Global energy demand will continue to rise in the future, resulting in increased carbon emissions. LÄS MER

  7. 5. A comparative Life Cycle Assessment (LCA) study of centralized and decentralized wastewater heat recovery in Stockholm, Sweden

    Master-uppsats, KTH/Energiteknik

    Författare :Deniz Pektas; [2021]
    Nyckelord :;

    Sammanfattning : The cities bear a large role in the climate crisis. However, this also means that they have a big potential in the transition towards sustainable communities and a sustainable world. Up to 90 % of energy use within the urban water cycle is allocated to hot water heating for end users. LÄS MER
