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. Evaluating the feasibility of chitosan as an adhesive for wood laminates and as a matrix for transparent wood

   University essay from KTH/Fiber- och polymerteknologi

   Author : Nihar Sakhadeo; [2023]
   Keywords : Transparent wood; Chitosan; Biobased adhesives; Biopolymers; Laminate; Transparent trä; Kitosan; Biobaserad adhesiv; Biopolymer; Laminat;

   Abstract : En av grundpelarna i alla hållbara system är införandet av en cirkulär ekonomi, som främjar återanvändning och återvinning av material. Plast är en av i utmaning i detta avseende på grund av den stora produktionsvolymen variation i sorter och långsamma nedbrytn. READ MORE

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

   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

6. 5. Sustainable Recycling of Electrolytes for Vanadium Redox Flow Batteries : Method development and Review (Bachelor Thesis)

   University essay from Karlstads universitet/Institutionen för ingenjörs- och kemivetenskaper (from 2013)

   Author : Reza Doulati; [2023]
   Keywords : vanadium redox flow batteries VRFB; eco-friendly recycling; precipitation of vanadium; vanadium oxides; Energy storage system; ESS; circular economy; sustainable recycling method;

   Abstract : Vanadium Redox Flow Batteries VRFBs are promising energy storage systems with highly recyclable electrolytes. The recycling of these systems usually involves ammonium-based salt precipitation steps, which produce toxicgases and contaminated water as waste. READ MORE
