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. Relationship between waste management in student accommodation and students' knowledge of waste management in relation to energy transition

   University essay from Uppsala universitet/Institutionen för geovetenskaper

   Author : Yong Lin; [2023]
   Keywords : Sustainable Development; Energy Transition; Waste Management; Waste Sorting; Pearson’s correlation coefficient; Student Accommodation;

   Abstract : In the context of the current energy transition and sustainable development, the promotion of waste separation and waste management is a good means of promoting the energy transition. Waste, when recycled, can contribute to the energy transition in many ways, for example by generating electricity, heating, recycling into raw materials for reuse and producing biofuels. READ MORE

4. 3. Recovery of Dialcohol Cellulose using Micro- and Ultrafiltration Processes

   University essay from Lunds universitet/Kemiteknik (CI)

   Author : Lina Näslund; Gabriella Petersson; [2023]
   Keywords : Membrane filtration; Ultrafiltration; Microfiltration; Dialcohol cellulose; DAC; Bioplastics; Chemical engineering; Process design; Technology and Engineering;

   Abstract : The waste management and production of plastic play a concerning part in global warming and continues to have a negative effect on the environment. A promising strategy to address this challenge is to develop new sustainable materials, to replace current fossil-based plastics. READ MORE

5. 4. Microplastics in Scanian wetlands : Sege river & Kävlinge river

   University essay from Malmö universitet/Institutionen för Urbana Studier (US)

   Author : Ludvig Stoltz; Pernilla Leijon; [2023]
   Keywords : plastic pollution; wetlands; microplastics; Scania; density separation; plastföroreningar; våtmarker; mikroplaster; Skåne; flotteringsmetod;

   Abstract : It is estimated that 75 million tons of plastics waste is currently in the ocean and expects to increase in line with plastic consumption. Plastic items in natural or aquatic environments are fragmented into smaller pieces called microplastics. Microplastics can enter rivers and lakes through sewage water to end up in wetlands where they sediment. READ MORE

6. 5. Protein Recovery from Alkaline Extracts: A Comparative Analysis of Isoelectric Precipitation and Ultrafiltration

   University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)

   Author : Anjay Sharma; [2023]
   Keywords : Rapeseed cake; Brewers spent grains; Protein recovery; Ultrafiltration; Alkaline extraction; Food engineering; Technology and Engineering;

   Abstract : Proteins are one of three macro-components of a diet. An increasing demand for products that can be a complete protein source exists. The vulnerability of the current food system towards environmental impacts and the inability to keep up with the rising population has shifted the focus on valorising underutilised by-products of the food industry.
