Dr.-Ing. Sebastian Petzet, BASF SE, has been awarded this year’s Willy Hager Prize by DECHEMA Gesellschaft für Chemische Technik und Biotechnologie e.V. (Society for Chemical Engineering and Biotechnology) and the Wasserchemische Gesellschaft (Water Chemistry Society), a division of the Gesellschaft Deutscher Chemiker (GDCH, German Chemical Society), in the name of the Willy Hager Foundation, Stuttgart, Germany.
The prize, which is endowed with € 6,000, honors outstanding work in the field of water or waste water treatment and was presented at the annual meeting of the Wasserchemische Gesellschaft (Wasser 2015), on May 11, 2015.
Sebastian Petzet is honored for his dissertation on phosphorus recovery from sewage, work performed at the Technical University of Darmstadt, Germany. His research is of particular importance because resources of phosphate, an essential plant nutrient and thus important for food production, are finite. Phosphorus must therefore be recovered from waste. Petzet has developed effective and inexpensive processes for the recovery from sewage sludge and sewage sludge ashes, which are particularly rich in phosphorus.
