  1. 21. Biobased iron pellet production : Assessment of the availability and sustainability of biomass as fuel for iron ore pellet production in LKAB

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

    Författare :Magnus Kemi; [2023]
    Nyckelord :bio-energy; biomass; coal; greenhouse gas emissions; industrial residues; LCA; LKAB; logging residues; iron ore; pellets; sinters; willow; sustainability;

    Sammanfattning : Iron production accounts for substantial shares of global coal use and GHG emissions. LKAB is Europe’s largest iron company and Sweden’s fourth-largest emitter of GHGs. To reduce its emissions, LKAB might implement biomass in iron ore pelletisation. LÄS MER

  3. 22. Status Mapping of tank to grave management of Low-GWP refrigerants.

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

    Författare :Sandra Parra Gimeno; [2023]
    Nyckelord :Refrigerant; Blends; Synthetic low-GWP refrigerant; Natural refrigerant; Global Warming Potential GWP ; Tank-to-grave; Interviews.; Köldmedier; Blandning; Globalt uppvärmningspotential GWP ; Låg-GWP köldmedier; Naturligt köldmedier; installation till destruktion; Intervjuer.;

    Sammanfattning : Refrigeration plays a vital role today in various residential, commercial, and industrial processes, requiring refrigerants to facilitate the cooling or heating processes. Over time, refrigerants have undergone significant changes to meet technological, social, environmental, and economic needs. LÄS MER

  4. 23. Preferences for carbon information : a Discrete Choice Experiment with Swedish non-professional investors

    Master-uppsats, SLU/Dept. of Economics

    Författare :Mahesh Kumar Shrestha; [2023]
    Nyckelord :discrete choice experiment; investment preference; GHG target; carbon information; target progress; carbon disclosure; non-professional investors; impact investing; sustainable and responsible investments; SRI;

    Sammanfattning : GHG targets, an aspect of carbon disclosure are an integral part of corporate carbon management and overall carbon accounting. GHG targets and the target-related attributes – including target difficulty, target progress, and external validation of target as a science-based target, along with past GHG emission performance are attributes related to carbon information that is increasingly included in the corporate carbon disclosures.

  5. 24. Optimization of alloys recovery in steel scrap sorting : Technological, economic and environmental considerations for a better chromium, nickel and molybdenum recovery in steel scrap

    Master-uppsats, KTH/Materialvetenskap

    Författare :Simone Quintè; [2023]
    Nyckelord :Steel scrap sorting; stainless steel; Chromium; Nickel; Molybdenum; alloys recovery; Laser Induced Breakdown Spectroscopy; revenue modeling; CO2 emissions modeling; Stålskrot Sortering; rostfritt stål; Krom; Nickel; Molybden; återvinning av legeringar; Laserinducerad nedbrytningsspektroskopi; intäktsmodellering; Modellering av CO2-utsläpp;

    Sammanfattning : Today’s steelmaking industry is highly dependent on steel scrap supply. In order to reduce the greenhouse gas emissions (GHGs) deriving from the steel industry, it is of utmost importance to ensure that high percentages of steel scrap are recycled, reducing the reliance on the traditional ore-based steelmaking, which is significantly more environmentally impactful.

  7. 25. Greenhouse gas emissions and carbon burial in a small pond

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Maria Carlson; [2023]
    Nyckelord :Pond; greenhouse gas; carbon dioxide; methane; nitrous oxide; flux; ebullition; carbon burial; Damm; växthusgas; koldioxid; metan; lustgas; flöde; ebullition; kolbindning;

    Sammanfattning : There are a lot of uncertainties when it comes to global greenhouse gas (GHG) emissions which affects society’s ability to effectively respond to climate change. Small ponds have been found to potentially play a large role in global warming. LÄS MER
