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

    University essay from Lunds universitet/Avdelningen för Teknisk vattenresurslära

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

    Abstract : 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. READ MORE

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

    University essay from SLU/Department of Molecular Sciences

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

    Abstract : 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. Selected PFAS in the water treatment at the waste-to-energy plant in Umeå : Investigating concentration and composition of selected PFAS in different water treatment steps

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Author : Amanda Carlund; [2023]
    Keywords : ;

    Abstract : The present study investigated the changes in concentration and composition of five selected PFAS substances in the water treatment at the waste-to-energy plant in Umeå. The five PFAS were PFHxA, PFHpA, PFOA, PFHxS and PFOS. As PFAS exists in a variety of consumer products, they will to some extent end up in waste incineration. READ MORE

  5. 4. Towards Water Resource Recovery Facilities : Environmentally Extended Techno-Economic Assessment of Emerging Sewage Sludge Management Technologies in Sweden

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Harry Tibbetts; [2023]
    Keywords : Circular Economy; Waste Valorisation; Systems Analysis; LCA; MFA; EFA; TEA; Hydrothermal Carbonisation; Cirkulär ekonomi; Waste Valorisation; Systems Analysis; LCA; MFA; EFA; TEA; Hydrotermal Carbonization;

    Abstract : Municipal sewage sludge (MSS) management varies widely between countries and legislative regimes. Within the European directive for sewage treatment France applies over half of MSS to arable land, while The Netherlands has banned the practice (Kelessidis et al, 2012). READ MORE

  6. 5. Microbial strains from compost originated from circulated side streams : impact on root growth and root hairs

    University essay from SLU/Dept. of Biosystems and Technology (from 130101)

    Author : Benjamin Pettersson; [2023]
    Keywords : Spent Mushroom Compost; Circulated side streams; Botrytis cinerea; Circular Bioeconomy; Soil health;

    Abstract : Spent mushroom compost, apple waste and other organic waste materials are of great potential to improve soil health, water holding capacity and to supress plant pathogens. Today compost is used in apple orchards as an additional fertilizer or soil amendment. READ MORE
