  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. Återbruk av byggnadsmaterial : En litteraturstudie om utmaningar som idag hindrar användningen av återbrukade byggnadsmaterial

    Uppsats för yrkesexamina på grundnivå, Mälardalens universitet/Akademin för ekonomi, samhälle och teknik

    Nyckelord :Reuse; deconstruction; obstacles; challenges; technical; economic; environmental;

    Sammanfattning : Purpose: This study aims to identify obstacles and challenges that prevent the reuse of building materials and bring forth possible solutions. But also to examine the technical-, economic- and environmental advantages and disadvantages of using reused building materials. LÄS MER

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

    Kandidat-uppsats, Uppsala universitet/Institutionen för samhällsbyggnad och industriell teknik

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

    Sammanfattning : 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. LÄS MER

  5. 4. Impact of the EU Battery Regulation on Circular Economy of EV Batteries- barriers and opportunities for battery repurposing

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Yi Chun Lin; [2023]
    Nyckelord :Battery waste management; EU regulation; repurposing; circular business models; End-of-life EoL batteries; Recycling; Hantering av batteriavfall; EU-förordning; Återanvändning; Cirkulära affärsmodeller; uttjänat batterier; Återvinning;

    Sammanfattning : This thesis presents a comprehensive exploration of the impact of EU battery regulations, Regulation (EU) 2023/1542, on end-of-life batteries, focusing on repurposing within the supply chain. We used both surveys and interviews to gather qualitative data from the stakeholders in the battery supply chain. LÄS MER
