1. 1. Techno-Economic Analysis of Dye Separation in Textile Recycling

   Master-uppsats, Lunds universitet/Avdelningen för Teknisk vattenresurslära

   Författare :David Lundberg; [2024]
   Nyckelord :Dye; Membrane filtration; Electrocoagulation; Techno-economic analysis; Pre-feasibility study; Technology and Engineering;

   Sammanfattning : 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. LÄS MER

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

   Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaper

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

   Sammanfattning : 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. LÄS MER

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

   Master-uppsats, Lunds universitet/Kemiteknik (CI)

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

   Sammanfattning : 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. LÄS MER

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

   Kandidat-uppsats, Malmö universitet/Institutionen för Urbana Studier (US)

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

   Sammanfattning : 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. LÄS MER

7. 5. Förbättrad svavelavskiljning i våt gasrening vid Högdalenverket

   Uppsats för yrkesexamina på grundnivå, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

   Författare :Marion Salem; [2023]
   Nyckelord :Sulphur oxides; Combined heat; and power plant; flue gas desulfurization; wet desulfurization; Svaveloxider; rökgasavsvavling; våta gasreningssystem;

   Sammanfattning : Vid Högdalens kraftvärmeverk produceras fjärrvärme och el, genom förbränning av hushålls och industriavfall. De negativa hälso- och miljökonsekvenserna som rökgasens föroreningar bidragit till, har lett till större intresse om teknikutveckling för rening av rökgasen ifrån miljögifter innan utsläpp till luft.
