1. 6. Study on Decolorization of Reactive-dyed Cotton through Fenton-oxidation as a Pre-treatment for Textile Recycling

   University essay from Högskolan i Borås/Akademin för textil, teknik och ekonomi

   Author : Elise Meurs; [2023]
   Keywords : Fenton-oxidation; advanced oxidation processes; decolorization; textile recycling; cotton; reactive dye;

   Abstract : 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.

3. 7. Impact of textile structure on mechanical recyclability

   University essay from Högskolan i Borås/Akademin för textil, teknik och ekonomi

   Author : Linnéa Bengtsson Creaser; [2023]
   Keywords : Textile recycling; mechanical recycling; textile tearing; fiber length; recyclability;

   Abstract : This thesis investigates the impact of yarn and fabric structure on the mechanical recyclability of textile structures. It focuses on variations in yarn twist and form (single or plied) as well as fabric type (woven or knitted) and their respective constructions. READ MORE

4. 8. Bio-based resins for digital light processing : Mechanical and degradable properties

   University essay from KTH/Materialvetenskap

   Author : Moa Eklund; Amanda Olofsson Ribrant; [2023]
   Keywords : Digital Light Processing 3D Printing DLP ; Additive manufacturing; Bio-based; Polymer; Thermosets; Covalent Adaptable Networks CANs ; Recycling; Characterization.; Digital Light Processing 3D Printing DLP ; Additiv tillverkning; Bio-baserad; Polymer; Härdplast; Kovalenta Anpassningsbara Nätverk CANs ; Återvinning; Karaktärisering.;

   Abstract : Thermosets are appropriate materials for various applications due to benefits such as heat resistance and good mechanical properties. The disadvantages of traditional thermosets from a sustainable manufacturing perspective are that they are usually derived from fossil resources, and also have permanent cross-linked networks that are difficult to break, making them non-recyclable.

5. 9. Biochar from separated digestate and pig manure as soil amendment

   University essay from SLU/Dept. of Soil and Environment

   Author : Lovisa Nissen; [2022]
   Keywords : separation; screw press; incubation study; CO2 emission; N mineralization;

   Abstract : The situation in and around the Baltic Sea, with large areas with hypoxia in the sea and areas in the watershed with a high concentration of animal farms, has led to a need to increase the nutrient recycling of animal manure. High levels of phosphorus (P) in the soil lead to leaching, and by reducing the P-level in organic fertilizers, this leaching can be reduced. READ MORE

6. 10. Closing hte loop in the textile industry : An investigation of current recycling possibilities for textiles supporting circularity in integrated product and production development

   University essay from Jönköping University/JTH, Produktionsutveckling

   Author : Sofia Östangård; [2022]
   Keywords : Circularity; Life Cycle Assessment; Recycling; Sustainable Manufacturing; Textile Production ;

   Abstract : Textile companies are facing a grand challenge towards achieving circularity in their business models. With a growing demand by customers for more sustainable textile products and the increased worldwide attention on how much the textile industry contributes to greenhouse gas emissions and water pollutions, this challenge needs to be addressed.
