    Sammanfattning : The trends in waste electrical and electronic equipment (WEEE) generation shows that their volume constantly increases, while the current waste management technologies have proven to be insufficient in order to meet the strict criteria and the new legislations of the European Union. Pyrolysis and thermal treatment in general could be a valuable solution for closing the loop of materials and could contribute to the energy demands of modern society. LÄS MER

  3. 12. Towards a Sustainable Biomass and Waste Refinery Based on Pyrolysis Combined with a Pretreatment Process

    Författare :Yuming Wen; Weihong Yang; Pär Jönsson; Tobias Richards; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; pyrolysis; anaerobic digestion; hydrothermal carbonization; refinery; biomass; waste; kinetics; LCA; Energiteknik; Energy Technology; Chemical Engineering; Kemiteknik;

    Sammanfattning : Some of the naturally accumulated biomass and the massive production of waste by human activities have caused serious environmental problems. The degradation of biomass and waste is one of the main greenhouse gasses (GHG) emission sources. LÄS MER

  4. 13. Gasification and Pyrolysis Characterization and Heat Transfer Phenomena During Thermal Conversion of Municipal Solid Waste

    Författare :Chunguang Zhou; Weihong Yang; Wlodzimierz Blasiak; Petr Stehlik; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; municipal solid waste; pyrolysis; gasification; heat transfer; CaO; CO2; reforming; numerical model; Energy Technology; Energiteknik; Chemical Engineering; Kemiteknik;

    Sammanfattning : The significant generation of municipal solid waste (MSW) has become a controversial global issue. Pyrolysis and gasification technologies for treating rejects from solid waste disposal sites (SWDSs), for which over 50 % of MSW is attributed to combustible species, have attracted considerable attention.
