Das Projekt "Optimierung der Rueckhaltefaehigkeit von Bentoniten und Bentonitmischungen in Schlammwaenden" wird vom Umweltbundesamt gefördert und von Universität Trier, Fachbereich VI, Lehrstuhl für Geologie durchgeführt. The proposed project is aiming at the development of new high-added value products based on bentonite and presenting a high retention capacity for a large variety of pollutants for environmental protection applications. The field of application of the newly developed products is in the trench wall slurry-technology with vertical barriers against organic and inorganic toxic leachates from contaminated industrial sites as well as already existing waste deposits which are not encapsulated according to modern technical standards.
