  1. 1. Residual Products in the Steel Industry Used for Briquetting

    Kandidat-uppsats, KTH/Materialvetenskap

    Författare :Alexander Eriksson; Linn Isaksson; Jacob Lilliebjörn; [2023]
    Nyckelord :;

    Sammanfattning : This report looks at the implementation of briquetting in the Swedish steel industry. Briquetting is a process in which residual products are mixed and compressed into a brick-like body in order to be added to the melt in a furnace. This report investigates the type of materials commonly used in briquetting as of today. LÄS MER

    Sammanfattning : With the urgency of cutting down CO2 emissions to reach climate neutrality by 2050, decarbonization of the steel industry is on the European Commission's agenda. Steelmaking accounts for 10 % of anthropogenic CO2 emissions and it is one of the most challenging sectors to decarbonize. LÄS MER

  4. 3. Klimatförbättrade betongelement : Betongstandarders och klimatdeklarationers påverkan på stomleverantörers klimatavtryck

    Kandidat-uppsats, KTH/Byggteknik och design

    Författare :Abbe Stenman; [2023]
    Nyckelord :;

    Sammanfattning : In 2021, the Swedish Institute for Standards (SIS) published an updated version of the Swedish concrete standard SS 137003. The new revised version makes it possible for concrete producers to include larger amounts of alternative binders other than Portland cement in the concrete mix. LÄS MER

  5. 4. Conditions for Industrial Symbiosis surrounding a hydrogen based steel industry

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

    Nyckelord :Industrial Symbiosis; H-DRI steelmaking; Industrial Symbiosis Networks; Waste management; Supplementary Cementitious Material SCM ; circular economy; Industriell symbios; H-DRI stålproduktion; Industriell Symbios-nätverk; restmaterialhantering; alternativa cementmaterial; SCM ; cirkulär ekonomi.;

    Sammanfattning : There is an ongoing transition to a more sustainable industry with lower climate impact. As part of this transition, the steel industry is expected to move from the conventional process for producing iron and steel using Blast Furnace (BF) and Basic Oxygen Furnace (BOF) processes, consuming large amounts of fossil fuels.

  7. 5. Praktisk tillämpning av klimatförbättrad betong : Litteraturstudie, observationsstudie och dokumentanalys

    Master-uppsats, KTH/Betongbyggnad

    Författare :Alina Mansour; [2022]
    Nyckelord :;

    Sammanfattning : Due to its good properties such as high strength, formability and durability concrete is one of the world's most widely used materials. At the same time, concrete, or rather the production of the concrete's main raw material, cement, has a negative climate impact. This is because a lot of carbon dioxide is emitted during the manufacturing process. LÄS MER
