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 ekonomiSammanfattning : 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.

2. Effect of a plant-derived nutraceutical on the tolerance of axenically-cultured Artemia towards abiotic or biotic stressor
Master-uppsats, SLU/Dept. of Animal Breeding and GeneticsSammanfattning : Aquaculture is one of the fastest-growing food-production industries worldwide accounting for almost half of fish used for human consumption. Super-intensive, intensive, and semi-intensive farming practices used to produce large farm fish are increasing the frequency of disease outbreaks which is a major problem affecting sustainable aquaculture growth.

3. Effect of High-Pressure Homogenization and Heat Treatment on the Emulsification Properties of Oat Protein Concentrate
Master-uppsats, Lunds universitet/Livsmedelsteknik och nutrition (master)Sammanfattning : This master thesis project was performed in collaboration with an agricultural cooperative Lantmännen Oats AB, who has developed a dry protein powder concentrate PrOatein™. The powder consists of oat proteins, dextrins, lipids and β-glucans. LÄS MER
4. Produktion av flyktiga fettsyror genom anaerobisk rötning av pappersmassa och papperslam
M1-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomiSammanfattning : Recently, there has been an increased interest in the production of volatile fatty acids from pulp and paper sludge using an immersed membrane bioreactor during anaerobic digestion. The production of biogas through anaerobic digestion has been a hot topic in recent years, but it is no longer economically viable due to competition from fossil fuels. LÄS MER
5. Comparative life cycle assessment of two desiccant wheel dehumidifiers with industrial application
Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : Humans spend around 80 percent of their lifetime indoors. The humidity level plays an essential part in indoor climate, both in non-industrial applications, such as thermal comfort, and industrial ones. Dehumidification is a technology in the field of thermal comfort and indoor climate to control humidity levels. LÄS MER
