News from the management

STG News January 2026
Dear customers, partners, and associates,
There have been changes at STG – and we want to bring you along directly. Changes are a part of every company, but this step is particularly significant for us:
We bid farewell to our long-standing managing directors Dr. Peter Hemmann, Helmut Heelemann, Thomas Schulz and Werner Bengsch. With their incredible experience, commitment, and passion, they have shaped STG over many years. We would especially like to highlight that Dr. Peter Hemmann and Helmut Heelemann are the founders of our company, and with their visionary strength they made STG possible in the first place.
For this, we say: A big, heartfelt thank you!
At the same time, we are starting anew with fresh energy and a new leadership team.
Norwid Hemmann, Stefan Reinke and Matthias Schützel are taking on central responsibilities from now on and bring a wealth of know-how, innovation, and energy with them.
And the best part: Andreas Birle will continue to be part of the management team. He will ensure that our values, stability, and clear direction remain intact – even as we introduce new impulses.
What does this mean for you?
In short: Everything remains good – just a bit more dynamic. We will continue to be your reliable partner in the glass industry, working at the highest level and developing solutions that are at the forefront of technology. Because that is what defines STG.
Thank you so much for your trust and long-standing loyalty. We look forward to embarking on the next phase with you – open, modern, and full of drive.
Warm regards,
Your STG Combustion Control GmbH & Co. KG
