    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Abhijith Namboodiri Kapothanillath; [2023]
    Nyckelord :EAF; Off-gas handling; CCS; Calcium Looping CaL ; Post-combustion; Waste heat recovery; Bio-coal; Negative emissions; Techno-economic analysis; EAF; Avgasrening; CCS; Calcium Looping CaL ; Efterförbränning; Återvinning av spillvärme; Biokol; Negativa utsläpp; Teknisk-ekonomisk analys;

    Sammanfattning : Steel is one of the most essential metals in the world, and it plays a vital role in various industries. The growing demand for steel has resulted in increased CO2 emissions, with the steel industry contributing to approximately 7% of global emissions of carbon dioxide. LÄS MER

  3. 2. Potential of waste-derived VFAs-bearing effluents as an external carbon source for MBBR denitrification of domestic wastewater

    Magister-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Författare :Seyed Reza Manafi Khosroshahi; [2022]
    Nyckelord :Volatile fatty acids; Denitrification; Wastewater treatment; Biological nutrient removal; Nitrate removal; Electron accepter; Carbon source; Electron doner; Moving bed biofilm reactor; Nanofiltration; VFA concentration; Discharge standards; Carriers; acclimatization; VFAs; MMBR; NF; WWTP; BNR;

    Sammanfattning : In conventional wastewater treatment plants, methanol, ethanol, and acetate are used as carbon source for the denitrification process in the biological nutrient removal. However, growing concern regarding economical costs and carbon footprints from the fossil-based production of these chemicals have forced the companies to look for other alternatives. LÄS MER

  4. 3. Perspectives on sustainable forest management by stakeholders in Östergötland

    Master-uppsats, Linköpings universitet/Tema Miljöförändring

    Författare :Katharina Charlotte Heimes; [2021]
    Nyckelord :Ecosystem services; sustainable forest management; bioeconomy; biodiversity conservation;

    Sammanfattning : The emerging bioeconomy in Europe requires the intensification of forestry to meet the market demand for biomass. The policy conflict between increasing production and halting biodiversity loss has fueled debates in Sweden on sustainable forest use and management in recent years. LÄS MER

  5. 4. Climate mitigation potential of the Swedish forest under different forest management regimes and levels of substitution effect

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Kristian Tufvesson; [2021]
    Nyckelord :Sustainable Development; forest management; scenario analysis; climate mitigation; sequestration; substitution;

    Sammanfattning : The Swedish forest is currently being debated as to how it should be managed to provide climate mitigation. Forest management can contribute to climate mitigation in mainly two ways. LÄS MER

  7. 5. Utvärdering av potential hos organiska restmaterial för avsättning i form av biokol

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

    Författare :Charlotte Karlsson; [2019]
    Nyckelord :Biokol; Organiskt restmaterial; Pyrolys; Metodutveckling;

    Sammanfattning : Runtom på den svenska marknaden finns olika strömmar av restmaterial som idag ofta uppfattas som avfall. För att uppnå ett mer cirkulärt samhälle finns förhoppningen om att dessa restmaterial skulle kunna nyttjas i en ny applikation och anses som en resurs istället för ett avfall. LÄS MER
