  1. 21. Sorption of per- and polyfluoroalkyl substances (PFAS) in contaminated water using sustainable organic- and inorganic materials

    Kandidat-uppsats, Örebro universitet/Institutionen för naturvetenskap och teknik

    Författare :Natalie Storm; [2022]
    Nyckelord :Sorption | PFAS | Contaminated water | Bark | Steel slag | Biochar | Activated carbon;

    Sammanfattning : Per- and polyfluoroalkyl substances (PFAS) are a large group of anthropogenic compounds with unique properties, including chemical inertness, resistance to many degradation processes and amphiphilic structure. This makes them useful in a range of applications, but also very persistent and bioaccumulative in nature, where PFAS have been linked to adverse health effects in both animals and humans. LÄS MER

  3. 22. Tracking of SVHC : Investigating current methods and creating a new method for tracking Substances of Very High Concern in products

    Sammanfattning : The aggregate stone industry produces stone – a critical material for the construction industry value chain, and is, thus, a valuable resource for building materials, highlighting the society’s need for critical products. The stone is mined and refined in so-called quarries. LÄS MER

  5. 24. 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.
