Predecessor Dr. Olaf Stange heads new BTS Southeast Asia office in Singapore

Leverkusen, Wendelsheim — Dr. Joachim Heck will succeed Dr. Olaf Stange as Managing Director of Ehrfeld Mikrotechnik BTS GmbH effective March 1, 2010. Stange will become the head of the new Southeast Asia regional office of Bayer Technology Services (BTS) in Singapore effective that same date.

After earning his degree in process engineering from Karlsruhe University of Applied Science and his PhD from Technical University, Dortmund, Heck began his professional career in 1987 as a development engineer in the process development department of Hoechst AG in Frankfurt. After holding several managerial positions in production and process development, he joined Aventis Research & Technologies GmbH as a business manager in 1997, and from 1999 served as production manager of the Chemicals business unit of Axiva GmbH. Following its integration into Siemens AG, he held a variety of management functions in the Process Development unit. Since 2008, Heck has served as unit manager and a member of the management team at Resources Technologies Management GmbH based in Frankfurt.

Since the integration of Ehrfeld Mikrotechnik into the BTS Group in 2004, Stange had systematically expanded the Wendelsheim facility near Mainz and turned it into one of the world’s leading suppliers in the field of microprocess technology. Modular microreaction technology is often superior to conventional technologies, particular when it comes to the development of processes for the production of new chemicals.
