  1. 21. Analysing the EU textile and clothing material flow with an emphasis on reuse-based value chains

    Master-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Författare :Paula Henrietta Herzberg; Fabian Pirrwitz; [2023]
    Nyckelord :System Dynamics; Reuse based value chains; Circular Economy; Waste Management.;

    Sammanfattning : Textile waste amounts and its utilization are pressing problems in the EU today, with further expected worsening as legislations come into play, increasing collection rates. The EU strives towards a more sustainable future, however this future might entail initial disimprovement, as consumption and disposal behaviour are further expected to increase. LÄS MER

  3. 22. Quality of Spent Mushroom Compost Amended with Organic Material- Effect on Nutrient Content and Plant Growth

    Master-uppsats, SLU/Dept. of Biosystems and Technology (from 130101)

    Sammanfattning : Bakgrund och problemdiskussion: Familjeföretag är oftast i behov inom olika områden av ett externt stöd som är oberoende från familjen och företaget. Revisorer och externa styrelseledamöter är två exempel som kan vara mycket värdefulla aktörer att ha i familjeföretag. LÄS MER

  7. 25. Thermodynamic modelling of the copper-zinc-tin ternary system : A study towards lead-free brass

    Master-uppsats, KTH/Materialvetenskap

    Författare :Caterina Radogna; [2023]
    Nyckelord :Brass-based alloys; Lead-free brass; Calphad; Thermo-Calc; Thermodynamic description; Mässingsbaserade legeringar; Blyfri mässing; Calphad; Thermo-Calc; Termodynamisk beskrivning;

    Sammanfattning : Lead (Pb) is frequently used as an alloying element in brass to enhance machinability and castability. However, this element poses a significant risk to human health and the environment. The 2021 revision of the Drinking Water Directive imposed stricter limits on Pb content in brass, encouraging the development of lead-free brass. LÄS MER
