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. Integrating Waste Heat from Hydrogen Production Into District Heating

   University essay from Lunds universitet/Institutionen för energivetenskaper

   Author : Fawzi Kayali; [2023]
   Keywords : Hydrogen; Electrolysis; Waste Heat Recovery; Combined Heat and Power Plant; District Heating; Simulation; Sustainable Heating Systems; Technology and Engineering;

   Abstract : The aim of this research is to explore the feasibility of the integration of waste heat from electrolyzers within a Combined Heat and Power (CHP) plant and district heating (DH) network and suggest a practical setup for integration. With the escalating emphasis on the development of green hydrogen through electrolysis powered by renewable energy, a substantial amount of waste heat is generated, typically left unused. READ MORE

4. 3. Modelling the chemical recycling of plastic waste via pyrolysis and analysing integration with existing refinery infrastructure

   University essay from Lunds universitet/Kemiteknik (CI)

   Author : Simon Dahl; [2023]
   Keywords : Pyrolysis; Recycling; Integration; Modelling; Simulation; Techno-economic; Plastic; Chemical engineering; Technology and Engineering;

   Abstract : Current plastic management is unsustainable as large amounts of plastic end up landfilled or in the ocean, necessitating an expansion of waste management infrastructure. Pyrolysis is a viable chemical recycling option, and in this report a pyrolysis model is constructed in Aspen Plus. READ MORE

5. 4. Varnishing of Fiber-based Closures

   University essay from Lunds universitet/Förpackningslogistik

   Author : Nisha Sunil David; [2023]
   Keywords : Varnishing; fiber-based closures; water-based spray coating; packaging; repulpability ; Technology and Engineering;

   Abstract : This research aims to investigate water-based varnishes and technologies to coat fiber-based closures to attain water barrier properties. To ensure recyclability the repulpability of coated and uncoated lids is tested. The research approach is exploratory. READ MORE

6. 5. Investigating the Potential of Circular Economy in Stockholm’s Craft Classes : A Case Study Comparing Secondary Wood to Virgin Wood Using LCA and LCC

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : Magdalena Smolic; Zin Haji; [2023]
   Keywords : Life Cycle Assessment; LCA; Life Cycle Costs; LCC; behavioral study; environmental impact assessment; circular economy; reuse; climate neutral cities; wood craft class; land use; water use; global warming potential; Livscykelanalys; LCA; Livscykelkostnadsanalys; LCC; Beteende studie; miljökonsekvensbedömning; cirkulär ekonomi; återanvändning; klimatneutrala städer; träslöjd; markanvändning; vattenanvändning; global uppvärmningspotential.;

   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
