Sustainability as vision 

Our vision is of a society characterised by sustainable growth, in which future generations can enjoy an intact environment with the same opportunities as we have today. Based on this holistic attitude, we are equally committed to customer satisfaction and to the job satisfaction of our employees. For this to be possible, of course, a solid financial basis needs to be assured.
