This is what Michael Müller, Governing Mayor of Berlin, says about our biological air filters:

“Berlin is the right place for innovative solutions to pressing challenges, especially in climate protection. The Berlin-based company Green City Solutions has achieved a convincing success in the Europe-wide Horizon 2020 funding program. I congratulate the employees for this. Green City Solutions’ successful creative project has the potential to solve urban climate problems that are increasingly affecting our urban areas. I also wish the Berlin-based company success in the implementation of its project, which is now imminent.”
