  1. 1. Varnishing of Fiber-based Closures

    Master-uppsats, Lunds universitet/Förpackningslogistik

    Författare :Nisha Sunil David; [2023]
    Nyckelord :Varnishing; fiber-based closures; water-based spray coating; packaging; repulpability ; Technology and Engineering;

    Sammanfattning : This research aims to investigate water-based varnishes and technologies to coat fiber-based closures to attain water barrier properties. To ensure recyclability the repulpability of coated and uncoated lids is tested. The research approach is exploratory. LÄS MER

  3. 2. Development and Optimization of Near-infrared spectroscopy

    M1-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Författare :Amanda Hahlin; [2023]
    Nyckelord :Near-infrared spectroscopy; NIRS; Textile sorting; Principal component analysis; PCA; Post-consumer end-of-life textiles;

    Sammanfattning : With the growing demand for sustainable options, the existing sorting capacities are limiting the potential for fiber-to-fiber recycling. With the help of near-infrared spectroscopy (NIRS), automated sorting of textiles with high accuracy is possible due to the easy access for polymer identification. LÄS MER

  4. 3. Framtagning av biobaserad oljematta för hemmabruk

    Kandidat-uppsats, Karlstads universitet

    Författare :Moa Sjönneby; [2022]
    Nyckelord :biobaserad; absorbera; olja; cellulosa; oljematta; GreenAll;

    Sammanfattning : Denna rapport handlar om ett produktutvecklingsprojekt genomfört som examensarbete för högskoleingenjörsprogrammet i innovationsteknik och design vid Karlstads universitet. Uppdraget tillhandahölls av Biosorbe AB som tillverkar ett material med namnet GreenAll. LÄS MER

  5. 4. Crosslinked Cartonboard - Challenges and possibilities

    Master-uppsats, Mälardalens universitet/Akademin för innovation, design och teknik

    Författare :Malin Elvin; [2022]
    Nyckelord :Cartonboard; crosslinking; mechanical properties; SCT;

    Sammanfattning : The need for sustainable packaging is growing, and plastic waste needs to be reduced. A suitable alternative could be fibre-based packaging and cartonboard, and several actions could enhance this alternative. This study investigates crosslinking, a method to create stronger bonds between the OH-groups in the material. LÄS MER

  7. 5. Post-Wildfire Debris Flows: Mapping and Analysis of Risk Factors in Western North America

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Annejet Tuinstra; [2021]
    Nyckelord :wildfires; debris flows; water repellent soil; North America; skogsbränder; jordskred; vattenavvisande jordlager; Nordamerika;

    Sammanfattning : Climate change is leading to in an increase in frequency and severity of wildfires, which in turn can result in the formation of runoff-initiated post-wildfire debris flows. This type of debris flows is, like most debris flows, triggered by heavy precipitation events. LÄS MER
