  1. 1. Life cycle assessment and structural analysis of renovation of Ulriksberg school building in Växjö

    Master-uppsats, Linnéuniversitetet/Institutionen för byggteknik (BY)

    Författare :Amir Ahaki Lakeh; Milad Tahmasbi; [2022]
    Nyckelord :Life cycle assessment; renovation measures; environmental impacts; structural analysis;

    Sammanfattning : Massive volumes of hazardous emissions have been produced by the construction sector for which some adequate steps are implemented, but the rising trend of emissions can still be seen. In this thesis, the goal is to identify and analyze renovation measures from primary energy use and environmental impacts perspective, according to Boverket’s mandatory provisions and general recommendations (BBR 2018), for an old school building.

    Sammanfattning : One of the most common building materials is concrete and it has been for a long time. To overcome its low tensile capacity concrete structures are normally reinforced with steel rebars. LÄS MER

  4. 3. Resurseffektiv tillverkning av elbilsbatterier : Forskningsöversikt över nuvarande utbudet av återvinning och återanvändning ur ett hållbarhetsperspektiv

    Kandidat-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :Raphael Bolos; Darwin Uthman; [2021]
    Nyckelord :;

    Sammanfattning : Med en snabbt tillväxt av elfordon på marknaden för att uppfylla alla globala mål som satts upp för att minska utsläppen av växthusgaser, förbättra luftkvaliteten och uppfylla kundernas behov eftersom att elbilar blivit mer trendiga i västvärlden, krävs det nya reformer som bidrar till en mer resurseffektiv tillverkning. Detta leder dock till stora utmaningar för avfallshanteringen vid slutet av batteriernas livslängd eftersom dålig hantering av dessa batterier kommer innebära stora negativa effekter på miljön, ekonomin samt olika sociala sammanhang.

  5. 4. Roadmap towards a Lean and Sustainable Production for Medium Sized Manufacturers: A Case Study

    Uppsats för yrkesexamina på avancerad nivå, Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Författare :Yasmeen Jaghbeer; Yvonne Motyka; [2016]
    Nyckelord :Value Stream Mapping; Sustainability Life Cycle Analysis; lean and sustainable production; medium sized manufacturers.; Value Stream Mapping; Sustainability Life Cycle Analysis; lean och hållbar produktion; medelstora tillverkningsföretag;

    Sammanfattning : Trends such as globalization, increased customer demands and the increased sustainability challenge are forcing medium sized manufacturers to rethink their production processes and start developing lean and sustainable production systems.Many of the developed tools and methods for the lean and sustainable production presented in the literature are not well suited for medium sized manufacturers with a lack of empirical case studies, and therefore investigating suitable approaches for improving the production and sustainability performances is needed in their case.
