Change in the OEKO-TEX® Management Board

OEKO-TEX® announces the departure of Georg Dieners. The Association’s Secretary General is leaving the organisation after 8 years in office. OEKO-TEX® expresses appreciation to Georg Dieners for his work and wishes him all the best for his future.

Until further notice, Hohenstein CEO Dr. Stefan Droste and TESTEX CEO Rainer Roten will co-manage the global provider of sustainability solutions for the textile and leather industry. The operations handled by the 17 OEKO-TEX® testing institutes are not affected by the change. OEKO-TEX® is working diligently to find a successor and will soon appoint a new Secretary General.

Because of their involvement in various OEKO-TEX® Association executive bodies, both interim Secretaries General are familiar with the issues and processes. As CEO of Hohenstein Textile Testing Institute, Stefan Droste has been entrusted with leadership since 2013. Rainer Roten has been the CEO, responsible for the entire TESTEX Group, since 2021, and has previously held management positions at several companies.
