   University essay from Göteborgs universitet/Institutionen för nationalekonomi med statistik

   Author : Felix Liljhagen; Aron Rehnberg; [2024-02-12]
   Keywords : ;

   Abstract : In line with technological development, electronic waste has become the world's fastest-growing waste category, increasing three times faster than the world's population. Although e-waste legislation covers about 66% of the world's population, the global recycling rate for e-waste is only 20%. READ MORE

3. 2. Process parameter optimisation for Waspaloy using Laser-Directed Energy Deposition with Powder

   University essay from Högskolan Väst/Institutionen för ingenjörsvetenskap

   Author : Johannes Lövhall; [2024]
   Keywords : Process parameter optimisation; Waspaloy; Laser-Directed Energy Deposition with Powder;

   Abstract : Material utilisation is of importance in the manufacturing industry formaking the most of each material, minimising waste and increasing cost-effectiveness. In this thesis, samples of Waspaloy built with the method of L-DED-P has been analysed in order to investigate how process pa-rameters influence the build quality and geometrical accuracy in as-builtobjects.

6. 5. 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
