The GfBU - Gesellschaft für Betriebs- und Umweltberatung mbH was founded in 1993 by Dr. Hans Köhler and Frank Herrmann. It successfully developed into a specialized service provider in the field of environmental and operational consulting.

In 2002 the GfBU-Zert - Certification Office for Environmental and Quality Management Systems GmbH was founded by Gerhard Gensicke and Dr. Steffen Wehrens. Her main focus is the certification of management systems and waste management companies.

As part of a corporate succession plan, the founders of GfBU-Zert registered the GfBU-Consult, Gesellschaft für Umwelt- und Managementberatung mbH, which took over both the customer base and the business areas and continues to develop them.
