Description: Das Projekt "Moeglichkeiten der Schwermetallrueckgewinnung von stark kontaminierten Flugaschen aus Biomasse-Heizwerken mit thermisch- und biochemischer Behandlung" wird vom Umweltbundesamt gefördert und von Technische Universität Graz, Institut für Grundlagen der Verfahrenstechnik und Anlagentechnik durchgeführt. This work has the aim to develop suitable technologies for processes able to recover heavy metals from contaminated fly-ashes and to evaluate their potential as well as the ecological and the economic side-constraints. The one topic of this project is to utilize the heavy metals concentrated in filter fly-ashes by separating them following the principles of heavy metal sublimation / condensation that will be gained from the project mentioned above. The biochemical part of the project investigates the potential of biochemical heavy metal separation from fly-ashes by dissolving them in organic acids. In a second step these dissolved heavy metals will be taken up by special bacteria strains that are able to upgrade them extra- or intracellular. These experiments will be carried out in collaboration with the Institute for Biotechnology at the Technical University of Graz.
