  1. 21. Pyrolysis and Detoxification of Waste Electrical and Electronic Equipment (WEEE) for Feedstock Recycling

    Författare :Panagiotis Evangelopoulos; Weihong Yang; Efthymios Kantarelis; Tobias Richards; KTH; []
    Nyckelord :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;

    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. 22. Anaerobic digestion of crop and waste biomass: Impact of feedstock characteristics on process performance

    Författare :Nges Ivo Achu; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Anaerobic digestion; Biofertilizer; Renewable energy; Sustainable operation;

    Sammanfattning : Anaerobic digestion provides an array of positive environmental benefits such as reducing greenhouse gas emissions, replacing mineral fertilizers, producing renewable energy and treating waste. However, pitfalls in anaerobic digestion such as poor methane yields, process instability, process failure and regional shortages of feedstock have limited the full exploitation of the anaerobic digestion process.

  4. 23. Influence of Escherichia coli feedstock properties on the performance of primary protein purification

    Författare :Mattias Råvik; Andres Veide; Åsa Emmer; KTH; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Downstream processing; cell surface properties; surface plasmon resonance; contact angle measurements; microelectrophoresis; aqueous two-phase partitioning; filtration; EBA adsorbents; high-pressure homogenisation; Biochemistry; Biokemi;

    Sammanfattning : Abstract The aim of the present study was to increase the understanding of how the cell surface properties affect the performance of unit operations used in primary protein purification. In particular, the purpose was to develop, set up and apply methods for studies of cell surface properties and cell interactions. LÄS MER

  5. 24. Trade-off analysis of forest ecosystem services – A modelling approach

    Författare :Xi Pang; Ulla Mörtberg; Berit Balfors; Brian Fath; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Forest bioenergy feedstock; Landscape simulation; Forest simulation; Ecosystem services modelling; Integrated sustainability assessment; Spatial optimization; Optimization heuristics; Mark- och vattenteknik; Land and Water Resources Engineering;

    Sammanfattning : Forest is a resource that is increasingly utilized for multiple purposes. The balance between energy demands and the long-term capacity of ecosystems to support biodiversity and other ecosystem services is crucial. LÄS MER

  7. 25. A Methodology for Identifying Transformation Pathways for Industrial Process Clusters: Toward Increased Energy Efficiency and Renewable Feedstock

    Författare :Roman Hackl; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; process integration; district heating; energy efficiency; biorefinery; total site analysis;

    Sammanfattning : The European process industry is facing major challenges. Modern, large-scale production facilities in other parts of the world are often more efficient. Furthermore, limited access to inexpensive shale gas from North America has led to an additional disadvantage for the European industry. LÄS MER
