  1. 1. Study on Decolorization of Reactive-dyed Cotton through Fenton-oxidation as a Pre-treatment for Textile Recycling

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

    Författare :Elise Meurs; [2023]
    Nyckelord :Fenton-oxidation; advanced oxidation processes; decolorization; textile recycling; cotton; reactive dye;

    Sammanfattning : In this master thesis, the feasibility of Fenton-oxidation for the decolorization of reactive dyed cotton is investigated as a potentially environmental-friendly preparatory treatment for mechanical/chemical recycling. Raw, knitted cotton is dyed with a black and a blue dye, whereafter preliminary tests are performed to investigate the influence of increasing Fenton- solution concentrations and different iron-sources on the efficiency of the discoloration, without carrying out complete optimization of the process-parameters.

  3. 2. The discoloration of polyethylene obtained from chemical separation of laminates: Investigating additives and other potential causes

    Master-uppsats, Lunds universitet/Förpackningslogistik

    Författare :Can Feng; [2021]
    Nyckelord :Delamination; multilayered packaging; polymer discoloration; plastic film; recycling; Technology and Engineering;

    Sammanfattning : PolyAl, the material composed of laminated polyethylene (PE) films and aluminum (Al) in carton, is a challenge in recycling due to the strong adhesion of the layers and the low value of the end products. In Europe, recent efforts to improve the circularity of carton packages include the chemical separation of PolyAl, in order to obtain higher values of the PE and Al separately. LÄS MER

  4. 3. Development and Scaling Up of Test Protocol to a Full-Scale Filter Rig to Investigate Soft Particle Filtration Efficiency in Biofuel Blends

    Master-uppsats, KTH/Kemiteknik

    Författare :Saurabh Shinkhede; [2021]
    Nyckelord :Heavy duty transportation; fuel filter clogging; soft particles; biofuel blends; filter test rig; Tunga transport; igensättning av bränslefilter; mjuka partiklar; biobränsleblandningar; filtertestrigg;

    Sammanfattning : Kommersiella tunga transporter står för en stor del av utsläppen av växthusgaser. För att minska det globala fotavtrycket hos kommersiella fordon är det vanligt att använda biodrivmedel som ”drop in” bränslen. LÄS MER

  5. 4. Erosion Behaviour of Thermal Barrier Coatings

    Master-uppsats, Linköpings universitet/Konstruktionsmaterial

    Författare :Caroline Wännman; [2021]
    Nyckelord :erosion; TBC; APS; EB-PVD; PS-PVD; failure mechanisms;

    Sammanfattning : Thermal barrier coatings (TBCs) are advanced material systems used in the hot sections of gas turbines. The TBCs are designed to provide insulation against hot gases by a ceramic top coat and to provide oxidation and corrosion resistance by a metallic bond coat. LÄS MER

  7. 5. The possibilities of recycling wash water at Vidinge

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Julia Mauritzson; [2020]
    Nyckelord :reuse; treatment; fresh-cut; water engineering; environmental engineering; avloppsteknik; vattenförsörjningsteknik; Technology and Engineering;

    Sammanfattning : Water is a resource of importance and with drier weather around the world, including Swe-den, there is a risk of too low levels of water to satisfy for instance households, animals and industries in the future. Fresh-cut fruit and vegetable industries are water intense and almost all process water is used in the washing process. LÄS MER
