    Sammanfattning : The waste management and production of plastic play a concerning part in global warming and continues to have a negative effect on the environment. A promising strategy to address this challenge is to develop new sustainable materials, to replace current fossil-based plastics. LÄS MER

  4. 3. 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

  5. 4. Effekter av packning av finfilter i fyllningsdammar

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Anton Jonsson; [2023]
    Nyckelord :Fyllnadsdamm; Finfilter; Packningsgrad;

    Sammanfattning : There are over 10 000 dams in Sweden of various types and sizes. Most of the larger dams were built around 1950-1970 when the Swedish hydropower was expanded. Since then, the knowledge of engineering dam structures has increased and there are new guidelines for how a dam should be built. LÄS MER

  7. 5. Exploring Particulate Filtration during Thermal Runaway in Lithium-Ion Battery Packs

    Master-uppsats, KTH/Kemiteknik

    Författare :Amanda Halvarsson; [2023]
    Nyckelord :battery pack; particles; thermal runaway; filtration; batteripack; partiklar; termisk rusning; filtrering;

    Sammanfattning : Med övergången till elektrifiering inom transport uppstår nya utmaningar när det gäller batterisystem som placeras i elfordon. Det finns för närvarande en möjlighet att minska riskerna med toxiciteten hos partiklar som sprutas ut med de gaser som bildas under termisk rusning i litiumjonbattericeller som är placerade i batterisystem.
