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. GREEN CITY ZONE A Case-Study in a Multi-Stakeholder Initiative within a Smart City

   University essay from Institutionen för tillämpad informationsteknologi

   Author : Florin Gabriel Dascalu; Nicole Dawn DiNatali; [2023-02-01]
   Keywords : net-zero emissions; multiple stakeholder management; construal level; temporal distance; system thinking; sociotechnical system theory; project management; smart city;

   Abstract : As climate change concerns have taken a central spot in mainstream discourse, there has been an emergence of green smart city projects, resulting in an increased demand for research in these areas. As the EU has pledged a reduction of emissions, various projects have arisen, such as Climate Contract 2030, Move21, and this thesis’ subject – the Gothenburg Green City Zone. READ MORE

4. 3. Biochar and district heating : The path to negative emissions

   University essay from Uppsala universitet/Institutionen för samhällsbyggnad och industriell teknik

   Author : Amanda Widlund; Thomas Norström; William Isaksson; Andreas Andersson; [2023]
   Keywords : biochar; pyrolysis; climate impact; carbon sink; district heating;

   Abstract : Uppsala Kommun is developing a new city district called Sydöstra staden (SÖS) as an innovative and transformative city district. A technical supply system that aligns with the district’s goals is pyrolysis. Pyrolysis is a process where biomass is heated without the supply of oxygen. READ MORE

5. 4. Unlocking the Potential of Solar-Hydro Hybrid Solutions: Feasibility and Economic Analysis

   University essay from Lunds universitet/Industriell elektroteknik och automation

   Author : Måns Rosberg; [2023]
   Keywords : Hydropower; Solarpower; Hybrid power production; Solar-hydro hybrid power; Reservoir storage; Energy storage; Pumped hydro power; Floating PV; PV; Photovoltaics; Technology and Engineering;

   Abstract : Hybrid solutions that combine multiple renewable energy sources, such as solar power and hydro power, are gaining popularity as a means of meeting the growing energy demands while minimising environmental impacts, but also as an opportunity of connecting solar power plants to the grid in areas where this might not be possible unless large investments are made. This master thesis aims to evaluate the feasibility and economic viability of integrating solar panels with an existing grid connection point at a hydro power plant, along with the introduction of an energy storage solution using a hydro power plant reservoir.

6. 5. Assessing Offshore Wind Power Potential in Fiji : A GIS-based Site Suitability and Feasibility Analysis

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

   Author : Felix Askenberger; Victor Renefalk; [2023]
   Keywords : Fiji; Offshore Wind Power; Graphical Information System; Multi-Criteria Site Suitability Analysis; Fiji; Havsbaserad Vindkraft; Grafiska Information System; Multikriterie platslämplighetsanalys;

   Abstract : Renewable energy, including offshore wind power, is expected to play a significant role in mitigating climate change and meeting a growing demand on electricity. Fiji, a Small Island Developing Nation in the South Pacific, needs large quantities of additional renewable energy to achieve its NDC goals and has good natural resources for offshore wind power.
