  1. 1. Varnishing of Fiber-based Closures

    University essay from Lunds universitet/Förpackningslogistik

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

    Abstract : 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. READ MORE

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

    University essay from Högskolan i Borås/Akademin för textil, teknik och ekonomi

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

    Abstract : 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. READ MORE

  4. 3. Crosslinked Cartonboard - Challenges and possibilities

    University essay from Mälardalens universitet/Akademin för innovation, design och teknik

    Author : Malin Elvin; [2022]
    Keywords : Cartonboard; crosslinking; mechanical properties; SCT;

    Abstract : 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. READ MORE

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

    University essay from Uppsala universitet/Institutionen för geovetenskaper

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

    Abstract : 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. READ MORE

  6. 5. Supercritical carbon dioxide as a green media for simultaneous dyeing and functionalisation : A study on disperse dyeing and silicone functionalisation for water repellency of polyester fabric

    University essay from Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Author : Anika Schulz; [2019]
    Keywords : Dyeing; supercritical carbon dioxide; silicone; water repellent; polyester; eco-friendly; technology; functionalisation; textiles; hydrophobic;

    Abstract : Textile processing methods such as conventional exhaustion dyeing, pre-treatments and printing consume high amounts of water and use partly toxic and hazardous chemicals which are non-degradable. These chemicals (e.g. READ MORE
