  1. 1. Techno-Economic Analysis of Dye Separation in Textile Recycling

    Master-uppsats, Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Författare :David Lundberg; [2024]
    Nyckelord :Dye; Membrane filtration; Electrocoagulation; Techno-economic analysis; Pre-feasibility study; Technology and Engineering;

    Sammanfattning : This study determines the technical and economic feasibility of separating dye from a process filtrate in industrial textile recycling using electrocoagulation or sequences of membrane filtration with microfiltration, ultrafiltration, nanofiltration and reverse osmosis. The lower requirements for treating this stream, compared to previously researched dyehouse effluents, left treatments not good enough for dyehouses viable for this process filtrate. LÄS MER

  3. 2. Waste or Want: Does processing have an effect on the desirability of upcycled food products? : a Swedish consumer acceptance study

    Master-uppsats, SLU/Department of Molecular Sciences

    Författare :Joséphine Lefrancq Fröjd; [2024]
    Nyckelord :Upcycled foods; food processing; consumer acceptance; contingent valuation method; consumer behavior;

    Sammanfattning : Food waste presents a significant obstacle to the food system’s transition to sustainability. With an ability to mitigate industrial food waste and its effects, the concept of upcycled food aims to safely adapt elements from the waste streams for human consumption by transforming them into ingredients to be used in novel ‘upcycled’ food products.

  4. 3. Investigation on the natural indigo dye for cotton fabric by using supercritical carbon dioxide

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

    Författare :Ryoi Takamatsu; [2023]
    Nyckelord :Dyeing; supercritical carbon dioxide; indigo; cotton; eco-friendly; textile;

    Sammanfattning : Concerns about the environmental impact of the textile industry are increasing, and there is an urgent need to develop and implement sustainable technologies. In particular, the environmental impact of dyeing, which emits a large amount of wastewater and chemicals, is one production process that needs to be resolved. LÄS MER

  5. 4. Characterization of Compost from Reusable Industrial Streams: : physical, Nutrient, and Microbial Properties

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

    Författare :Ellen Ek Moreau; [2023]
    Nyckelord :Spent mushroom compost; apple orchard waste; soil amendment; compost optimization; circular agriculture;

    Sammanfattning : The increasing global population, combined with soil degradation, poses challenges to food security, and raises concerns about the excessive and long-term use of conventional fertilizers. Evaluating sustainable alternative by-products for their soil-improving properties could offer a potential solution, particularly for Swedish fruit producers who can tap into local waste streams as a circular source of plant nutrients.

  7. 5. Effect of different food by-products on Tenebrio molitor growth and development in an industrial environment

    Master-uppsats, SLU/Dept. of Ecology

    Författare :Anton Laggar Andreasson; [2023]
    Nyckelord :Tenebrio molitor; yellow mealworm; growth; development; industrial farming; wet feed; dry feed; by-products; insects; insects as food and feed; maturation; pupation;

    Sammanfattning : Due to an increasing need for high-quality protein around the world, eyes are turning towards alternative methods of farming, such as insect farms. As insects can eat what humans cannot, e.g. food by-products, they can be a part of sustainable food systems. LÄS MER
