  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. Predicting Chemical-Gene Interactions

    University essay from Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Author : Ali Chishti; [2023-08-04]
    Keywords : Pesticides; Small streams; Prediction modelling; Chemical-protein-gene interactions; Aquatic organisms;

    Abstract : Pesticide use in agriculture has become a growing concern as it can have detrimental effects on the environment. The excessive use of these chemicals often leads to them seeping into nearby water bodies, causing harm to aquatic organisms. READ MORE

  4. 3. Turning Oil Into Water : Water security in the Middle East and North Africa

    University essay from Uppsala universitet/Statsvetenskapliga institutionen

    Author : Frida Salberg; [2023]
    Keywords : Water security; peak oil; desalination;

    Abstract : This study examines the relationship between oil supply and water security in the Middle East and North Africa. The aim is to see if countries without oil have a harder time mitigating water scarcity, as well as if countries with oil can be expected to become more vulnerable when oil becomes scarcer.

    Abstract : This thesis evaluates the environmental, economic, and social impacts of implementing secondary wood from recycling centers into wood crafts in Stockholm schools. The thesis is conducted in a case study setting as a part of the "Climate Neutral Stockholm 2030" sub-project 3. READ MORE

  6. 5. Användning av krävande ballastmaterial vid betongtillverkning - En laborativ utvärdering av absorptionshämmande tillsatsmedel för att möjliggöra användning av glimmerrik bergkross och återvunnen betong som ballast

    University essay from Lunds universitet/Avdelningen för Byggnadsmaterial

    Author : Anna Hagberg; Andreas Andersson; [2023]
    Keywords : Absorption inhibitor; admixtures; aggregate; biotite; calorimetry; compressive strength; concrete; heat development; mica; recycled concrete; workability; Technology and Engineering;

    Abstract : Detta examensarbete utvärderar ett absorptionshämmande tillsatsmedel för att möjliggöra användningen av krävande ballast vid betongtillverkning. Den huvudsakliga anledningen till att ballasten benämns som krävande är att den har ovanligt hög absorptionsförmåga. READ MORE
