After studying and doing her doctorate thesis  in organic chemistry in Münster, Monika Kohla became acquainted with industrial environmental protection at Siemens in Berlin. This awakened a desire for "more," so when she was given the opportunity to set up an "environmental department" at a regional textile association, she returned to Münster.

Over the next 25 years, she developed  the environmental unit to become the department for the environment, energy and consumer protection - an indication of the increasing importance of these issues for the industry. Her expertise and the benefits of intensive support for companies, which became a model nationwide, led other associations to set up similar departments.

When REACH came along, Monika Kohla became known throughout Europe for practical pilot projects, the results of which she eventually presented to a delegation of the German government in Brussels. Her chemical expertise led her to become a leader in helping importing garment companies to avoid pollutants regulated under REACH.

In 2017, she joined GermanFashion, the association of the garment industry and IVGT, representing textile producers, enabling her to advise around 500 companies nationwide on REACH, environmental protection and supply chain sustainability.

Dr. Haug began his professional career in 1993 with a doctoral thesis from ETH Zurich in the pocket, where he developed the principle for a non-enzymatic optical glucose sensor. Upon joining TESTEX, he introduced analytical chemistry to the laboratory's portfolio and immediately began working on the implementation of the OEKO-TEX® STANDARD 100 certification in Switzerland.

For many years, Dr. Haug chaired the Technical Committee of the OEKO-TEX® Association, playing an important role in shaping the OEKO-TEX® STANDARD 100.
