About Us

The brand for innovative products in the surface technology sector


It is through sustainability that we want to satisfy the needs of the people of today with the bio-chem products and technologies, and to use resources in a way that also further generations may benefit from them.

As early as 2002 to 2004 we took part in the be.st project of “Cooperative sustainability-oriented benchmarking” of future e.V., together with four other small and medium-sized enterprises (SMEs). It was accompanied scientifically by the Wuppertal-Institute for Climate, Environment and Energy. This innovative project established a connection between the demanding requirements of sustainability and the application in SMEs, and with its help the corporate processes of Bio-Circle Surface Technology GmbH could be developed following the principles of sustainability and compared to other enterprises.


Founded as a kind of garage start-up by graduate engineers Ulrich and Manfred Berens, over the years CB Chemie und Biotechnologie has developed into an internationally operating enterprise with approx. 70 employees in Germany. Branch offices and production sites have been established in Europe and the world; the distribution network in Germany has been expanded continuously. The company’s constant presence at domestic and international trade fairs and exhibitions also helps promote innovative reactions to ideas and markets.

As of 2010, CB Chemie is now called Bio-Circle Surface Technology GmbH. Against the backdrop of our internationally oriented corporate strategy the change of name enables us to design and strengthen our know-how globally.
