We believe in a responsible economy

We, that is Torsten Merker, Arne Ahrens and Andreas Koch (from left to right in the picture), have many years of experience as a team of experts in tourism, trade and craft.


Over 400 hotels as well as well-known tourism companies such as DER Touristik or TUI and regions such as Schleswig-Holstein, Crete and Mauritius are among our customers, as are Edeka markets and large bicycle dealers. We are happy to support you with our experience as well if you wish!

Our values and what we stand for

We are convinced that we need to rethink the traditional way of doing business. Both the way we deal with people and our earth have reached noticeable limits for us. We have reached a point where we feel that it cannot go on like this. Energy efficiency, environmental protection and sustainability, properly lived and used, are the best answers for us to actively shape the future now. Our values at blueContec are therefore based on sustainability, community and cooperation, passion for our mission and freedom. We want to actively bring this into the discussion and each of our projects.
