Production
With our two production sites in Germany, we stand for “Made in Germany”. However, a decisive factor for you is naturally what takes place there. In this section, we want to therefore give you an understanding of the fundamental backgrounds and competencies at our two sites in Witten and Wittenberge.
First of all: The list of our certifications is long – for a good reason. They are proof that our production is always subject to the highest quality standards; this makes you successful in your markets.
Sustainability and our striving to achieve innovative solutions are a matter of course for us at all our sites. And both production sites share the same ambition to continuously develop further. Because your requirements change, new customer needs arise and extended technical possibilities open up further potential, which we will always utilise to your benefit.

Production Site Witten
The industrial site in Witten in the southwest of the Ruhr district was originally founded in 1905 as a soap factory under the name of “Märkische Seifen-Industrie Witten”, which initially produced detergents and cleansing agents in its steadily growing production plants. Later on, the focus of production was extended to include oleochemistry in order to also produce the raw materials needed for making soap. A significant oleochemical production site for the most diverse materials based on natural fats and oils developed from these beginnings over the following decades.
Our production facilities all represent the state of the art and are operated with monitoring and process control technology. We have already been meeting the high GMP (Good Manufacturing Practice) standards of the pharmaceutical industry since 2005 with our production processes. This also includes regular audits by the district government of Arnsberg (most recently in summer 2024) to confirm the GMP certificate and by the U.S. Food and Drug Administration – FDA – (most recently in January 2020).
