  1. 1. 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. 2. Life Cycle Assessment of Urban Underground Oyster Mushroom Farming

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

    Författare :Emile Lemaitre; [2022]
    Nyckelord :Life cycle assessment LCA ; Urban mushroom farming; Oyster mushrooms; Urban agriculture; Livscykelanalys LCA ; Urban svampodling; Ostronskivling; Stadsodling;

    Sammanfattning : Global food production has been recognized as the single largest driver of environmental degradation and transgression of planetary boundaries. Providing healthy food sustainably to a growing, mostly urban population will require radical changes to the food system. LÄS MER

  4. 3. Life cycle assessment of hybrid systems for rural electrification in Bolivia

    Uppsats för yrkesexamina på grundnivå, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Sandu Seres; [2021]
    Nyckelord :Diesel; Stirling; Photovoltaic; impact category;

    Sammanfattning : Bolivia is a developing country in South America. Many rural communities still lack access to electricity. The extension of the National Grid System to all rural communities is not feasible due to economic and topographic challenges as well as the environmental problems that may arise. To tackle these problems, Off-grid solutions are implemented. LÄS MER

  5. 4. Klimatpåverkan av att pyrolysera dränerad torv : en konsekvens-LCA för användandet av biokol i betong

    Uppsats för yrkesexamina på avancerad nivå, SLU/Dept. of Energy and Technology

    Författare :Jesper Westerin; [2018]
    Nyckelord :pyrolys; dränerad torvmark; livscykelanalys; stycketorv; global uppvärmning; fjärrvärme;

    Sammanfattning : In Sweden there is approximately 6.4 million hectares of peatlands, which is about 15 % of the total land area. A significant proportion of peatlands, 2,4 million hectares, is affected by human drainage to promote agriculture and forest production. LÄS MER

  7. 5. A Comparative Study of Social, Environmental and Economic Aspects of Paraffin and Wood Pellets Used for Cooking in Low Income Households in South Africa : A Minfor Field Study

    Master-uppsats, KTH/Miljöstrategisk analys (fms); KTH/Skolan för arkitektur och samhällsbyggnad (ABE)

    Författare :Jenny Svensson; Alice Kjellson; [2015]
    Nyckelord :Minor Field Study MFS ; sustainability; wood pellets; paraffin; life cycle assessment; low income households; South Africa; fältstudie MFS ; hållbarhet; träpellets; paraffin; livscykelanalys; låginkomsthushåll; Sydafrika;

    Sammanfattning : The majority of low income households in South Africa have limited access to electricity, and typically cook on stoves fuelled by paraffin. Paraffin represents a fossil fuel. It is a relatively cheap fuel in South Africa. Another fuel that can also be used for cooking is wood pellets, which is a renewable fuel. LÄS MER
