1. 11. Exploring different thermoplastics from lignocellulosic building blocks and monomers

   Författare :Olivier Bonjour; Centrum för analys och syntes; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Biobased plastics; Biobased polymers; Polymethacrylates; Polycarbonates; Polyesters; Poly beta-thioether ester s; Chemical recycling; Biobased plastics; Biobased polymers; Polycarbonates; Polymethacrylates; Poly beta-thioether ester s; Polyesters; Chemical recycling;

   Sammanfattning : The need to replace conventional fossil-based plastics is becoming more imperative. As climate change is more visibly affecting our society, employing non-sustainable resources to produce plastics is aggravating the problem. LÄS MER

3. 12. Utilizing lignocellulose-based building blocks to develop recyclable polyesters

   Författare :Nitin Valsange; Centrum för analys och syntes; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biobased; Polyester; Recycling;

   Sammanfattning : With the growing global population and the demand for new applications, the production of fossil-based plastics is continuously increasing. This has led to serious environmental concerns about the depletion of fossil resources, land and marine pollution, and generation of greenhouse gas emissions. LÄS MER

4. 13. Towards sugar- and lignin-based polyesters and polyurethanes with enhanced properties

   Författare :Niklas Warlin; Centrum för analys och syntes; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Polyesters; Polyurethane; Bio-based Materials; HMF; Recycling; Vanillin;

   Sammanfattning : The enormous production and consumption of fossil-based plastics has caused severe environmental challenges such as pollution of the ocean, increased CO2-emissions, and various health problems. Many ofthese concerns are intimately connected to the use of fossil fuels in the production of polymers. LÄS MER

5. 14. Analytical techniques for quality assessment of separated and commingled recycled polymer fractions

   Författare :Walker Camacho; KTH; []
   Nyckelord :recycling; hdpe; pp; blends; nylon 6.6; abs; water content; mae; gc-ms; mir; chemiluminiscence;

   Sammanfattning : Different methods for quality assessment of separated andcommingled plastics from household and electronic waste havebeen developed. Especial attention has been given tospectroscopic methods since they are non-destructive andrequire little or no sample preparation at all. LÄS MER

7. 15. Functional Properties and Morphology of Recycled Post-consumer WEEE Thermoplastic Blends

   Författare :Erik Stenvall; Chalmers tekniska högskola; []
