    Författare :Erik Stenvall; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; morphology; melt-blending; compatibilisation; extrusion; SEBS; WEEE; physical ageing; TOF-SIMS; co-continuous; chemical degradation; plastics recycling;

    Sammanfattning : This work concerns a waste electrical and electronic equipment blend of recycled plastics (WEEEBR), reprocessed from a low density thermoplastics batch (600 kg) by removal of non-thermoplastic contamination (1.2 weight % (wt%)). LÄS MER

  3. 17. Material recycling of post-consumer flexible polyethylene packaging waste

    Författare :Ezgi Ceren Boz Noyan; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; degradation; polyethylene; melt-compounding; washing; post-consumer flexible packaging waste; mechanical properties; plastics recycling;

    Sammanfattning : The mechanical and thermal properties of recycled post-consumer flexible polyethylene packaging waste was studied, using material collected and sorted on a large-scale from two sources. Unwashed, laboratory-scale washed, industrial-scale washed, and industrial-scale washed and melt-compounded (industrially recycled) materials were used. LÄS MER

  5. 19. Pyrolysis of mixed plastics and paper to produce fuels and other chemicals

    Författare :Nanta Sophonrat; Weihong Yang; Linda Sandström; Tobias Richards; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Pyrolysis; Mixed plastics and biomass; Cellulose; Refuse derived fuels RDF ; Paper rejects; Interactions; Stepwise pyrolysis; Calcium oxide CaO ; Chemical Engineering; Kemiteknik; Energy Technology; Energiteknik;

    Sammanfattning : As the world population and economy grow, higher consumption results in higher waste packaging, plastics and paper residues. Pyrolysis offers a way to recover fuels and other chemicals from this waste fraction. LÄS MER
