The senior owner - Professor Dr. Gunther Krieg - founded the company, which is close to and connected with the Karlsruhe Insti- tute of Technology (KIT). Powersort is part of the product portfolio of Unisensor, which specialises in sensor sys- tems technology for gas, fluid and solid mate- rial. Industries supplied include the beverage, gas, compressed air and recycling sectors. The first Powersort was sold in 2007. To date, the company has sold to leading recycling firms in Europe, in the US and most recently to Mexico. In December 2010 Unisensor/Powersort was one of three nominees for the German Presi- dent’s “Award for Technology and Innovation”, which honours researchers and engineers who develop ground-breaking projects and products for the market. The award not only recognises scientific achievement, but also takes account of the marketability of the innovations and the asso- ciated potential for creating jobs. www.unisensor.de The developers of Powersort: J. Bohleber, Prof. G. Krieg, D. Fey (f.l.t.r) Kornel Büsser , Managing Director and Production Manager commented: „The most significant problem was silicone. In 2006 we installed the newly developed prototype of Powersort in our factory. The problem was instanta- neously solved. We are now also able to recognise those foreign plastic particles, which are not PET, but have the same colour as PET, and eliminate same. In the last four years since installation, we have cooperated closely with Unisensor to adjust their sorting system to a factory environment utterly different from laboratory conditions. Unisensor has benefited from our experience. We have recently exchanged the prototype for a new Powersort.”
