  1. 1. 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

    Sammanfattning : Biomass from forests provides society with energy, materials and chemicals, thus contributing to the circular bioeconomy. The majority of biomass is found in the wood tissue of trees. LÄS MER

  4. 3. Volatile Fatty Acids as a Key to Sustainability and Circularity in Polyhydroxyalkanoates Production

    Författare :Hoang Danh Vu; Dan Åkesson; Pau-Loke Show; Högskolan i Borås; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bioplastics; food waste; polyhydroxyalkanoates; volatile fatty acids; immersed membrane bioreactor; acidogenic fermentation; Resource Recovery; Resursåtervinning;

    Sammanfattning : The negative consequences of plastic pollution on both environmental and socio-economic aspects have motivated the development of sustainable and renewable materials to replace the petroleum-based plastic. Polyhydroxyalkanoates (PHAs), which are bioplastics, having an outstanding biodegradability and rather comparable thermal and mechanical properties, are potential alternatives for the replacement of conventional plastics.
