The wave-shaped acoustic panel Troldtekt wave is one of five finalists in the Design category at the Querdenker Awards 2015, which pay tribute to creative talent. The awards are being presented on 25 November during a congress in Munich, at which Michael Braungart, who founded the Cradle to Cradle concept, will be talking, among others.

Since it was launched in June 2015, Troldtekt wave has already won three prizes: the German Design Award, the Green Product Award and the ICONIC Award.

It is now possible to vote for the finalists online.
