  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. Biokinetic Characterization of Methane Oxidizing Microbiomes Co-metabolizing Trace Organic Chemicals

    University essay from Lunds universitet/Teknisk mikrobiologi

    Author : Hugo Möller; [2024]
    Keywords : Methanotrophs; organic micropollutants; co-metabolism; biodegradation; applied microbiology; Earth and Environmental Sciences;

    Abstract : The presence of organic micropollutants (OMPs) in wastewater effluents is concerning, as they pose a threat to human and aquatic health. Biodegradation via methane-oxidizing bacteria (MOB) is an attractive option, as the method is cheap and effective. MOB can co-metabolize a variety of substrates, there among organic micropollutants.

  4. 3. “The Effects of Sensory Marketing in Physical Second-Hand Stores” : A qualitative study of how applying sensory marketing in a physical second-hand store can influence consumers to choose more sustainable options while shopping for apparel.  

    University essay from Linnéuniversitetet/Institutionen för management (MAN)

    Author : Kajsa Carlsson; Carina Klingestam Lundqvist; [2023]
    Keywords : Second-hand; Sustainability; Sensory Marketing; Physical Stores; Purchase Decisions; Customer Experience; Fast Fashion;

    Abstract : The emergence of online stores specializing in fast fashion apparel has presented a significant challenge to brick-and-mortar stores and has had detrimental consequences for the environment. Consequently, it is essential for physical stores to stay informed about emerging trends in physical store design. READ MORE

  5. 4. Stability improvement to a ruthenium catalyst for partial oxidation of methane

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Melker Axelsson; [2023]
    Keywords : catalysis; reaction engineering; kinetics; partial oxidation; chemical engineering; Technology and Engineering;

    Abstract : Catalytic partial oxidation of methane (CPOM) is an energy-efficient alternative to steam reforming, the currently prevailing method for energy production from natural gas. Hulteberg Chemistry & Engineering AB has developed a catalyst for the partial oxidation of methane into syngas, for use in solid oxide fuel cells. READ MORE

  6. 5. Risk assessment of non-intentionally added substances in polyester yarn made from recycled polyethylene terephthalate (PET)

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Kristina Arnqvist; [2023]
    Keywords : r-PET; polyester yarn; NIAS; risk assessment;

    Abstract : Polyester is a synthetic material made from polyethylene terephthalate (PET), which is synthesised from fossil raw materials. Many clothing manufacturers are using polyester in their clothing, which, from an environmental perspective, creates a non-sustainable cycle. READ MORE
