   Kandidat-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomi

   Författare :Mathilda Stenström; Elin Johnsson; [2022]
   Nyckelord :Waste management; bio-based materials; biodegradable materials; bioeconomy; mixed fiber; circular economy; end-of-life; sustainability; monomaterial; textile fiber content.; Avfallshantering; biobaserade material; bionedbrytbara material; bioekonomi; blandfiber; cirkulär ekonomi; end-of-life; hållbar utveckling; monomaterial; textilt fiberinnehåll.;

   Sammanfattning : Den globala efterfrågan på textila produkter ökar ständigt, samtidigt som branschen står inför stora utmaningar gällande dess höga klimat- och miljöpåverkan. Omkring 65 miljoner ton syntetiskt material framställs årligen, där polyester står för 82% och dominerar marknaden. LÄS MER

3. 2. Reaching Net-Zero in the Chemical Industry - A study of roadmaps for reducing greenhouse gas emissions

   Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Miljö- och energisystem

   Författare :Ylva Kloo; [2022]
   Nyckelord :Chemical industry; roadmaps; scenarios; net-zero emissions; recycling; biobased feedstock; CCU; CCS; electrification; efficiency improvements; framework conditions; Technology and Engineering;

   Sammanfattning : Following the decision set by the EU of a net-zero greenhouse gas emission target for 2050, several industries have made roadmaps for how these reductions will be achieved. This thesis investigates the chemical industry roadmaps in order to assess how they envision their role in reaching the EU target. LÄS MER

4. 3. Evaluation of the recyclabillity of a lignin-based biopolymer

   Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Materialvetenskap

   Författare :Eric Hacksell; [2021]
   Nyckelord :recycling; recyclability; lignin; Renol; PP; mechanical recycling; Recyclass; återvinning; lignin; Renol; återvinningsbarhet; Recyclass;

   Sammanfattning : The use of plastic materials has changed the packaging industry, the construction industry, the automotive industry, and many others drastically. Plastics are also abundant in our everyday life. However, its downsides in the society are undeniable and are starting to get attention from law makers, the general public and industries alike.

5. 4. Exploring the sustainability potential of an algae-based wood adhesive : Comparative and explorative environmental life cycle assessment of algae- vs. formaldehyde- based adhesives for particleboard production

   Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

   Författare :Charlotte Rasche; [2020]
   Nyckelord :life cycle assessment; particleboard; bio-adhesive; wood-adhesive; bio-resin; algae; macroalgae; seaweed; kelp; formaldehyde; greener production; environmental impacts; biobased; design for the environment;

   Sammanfattning : Adhesives used for wood composites such as particleboard are conventionally of petrochemical nature with formaldehyde as a base substance and represent a pain point in the industry due their toxic emissions. Consequently, adhesives are subject to an agenda to develop more benign, low-impact alternatives. LÄS MER

7. 5. Upscaling of FDCA Synthesis from HMF to an Industrial Scale

   Master-uppsats, Lunds universitet/Kemiteknik (CI)

   Författare :Linnéa Wahlberg; [2020]
   Nyckelord :FDCA; HMF; Plastics; Sugar; Biobased; PEF; Industry; Industrial scale; Production; Upscaling; 2; 5-furandicarboxylic acid; 5-hydroxymethylfurfural; Chemical engineering; Kemiteknik; Technology and Engineering;

   Sammanfattning : To support the transition into green plastics, the upscaling and economic analysis of 2,5-furandicarboxylic acid (FDCA) synthesis from 5-hydroxymethylfurfural (HMF) was done. The project can be described as a plant-to-plastics process, with sugar beet-derived HMF as a starting point. LÄS MER
