  2. 1. Towards a Sustainable Biomass and Waste Refinery Based on Pyrolysis Combined with a Pretreatment Process

    Author : Yuming Wen; Weihong Yang; Pär Jönsson; Tobias Richards; KTH; []
    Keywords : 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;

    Abstract : 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. READ MORE

    Author : Panagiotis Evangelopoulos; Weihong Yang; Efthymios Kantarelis; Tobias Richards; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Pyrolysis; WEEE; solvent extraction; brominated flame retardants; Tetrabromobisphenol A; Auger reactor; Πυρόλυση; ΑΗΗΕ; εκχύλιση με διαλύτη; βρωμιωμένα επιβραδυντικά φλόγας; Τετραβρωμοδιφαινόλη Α; Pyrolys; WEEE; lösningsmedelsextraktion; bromerade flamskyddsmedel; tetrabrombisfenol A; Teknisk materialvetenskap; Materials Science and Engineering;

    Abstract : 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. READ MORE

  5. 3. Environmental assessment of incinerator residue utilisation

    Author : Susanna Toller; Jon Petter Gustafsson; Dan Berggren Kleja; Erik Kärrman; Thomas H. Christensen; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MSWI bottom ash; wood ash; recycling; LCA; environmental assessment; geochemical speciation modelling; dissolved organic matter; copper Cu ; Environmental engineering; Miljöteknik;

    Abstract :  In Sweden, utilisation of incinerator residues outside disposal areas is restricted by environmental concerns, as such residues commonly contain greater amounts of potentially toxic trace elements than the natural materials they replace. On the other hand, utilisation can also provide environmental benefits by decreasing the need for landfill and reducing raw material extraction. READ MORE
