We have launched the digital whistleblower portal as a further building block to promote open, confidential and, if necessary, anonymous communication within the company. The portal enables whistleblowers to directly report violations of laws or regulations, as well as grievances within the company, while at the same time protecting the whistleblower.
We have been refining raw materials ourselves for over 130 years and focus on the highest quality. We primarily use natural materials, which we extract from our own deposits and refine into high-quality products using state-of-the-art processes. Our claim: efficient use of resources and sustainable production.
Our most important raw materials at a glance:
Sedimentary rock
Millions of years old mineral mixture that is thoroughly purified in complex and carefully controlled processes. This unique mixture forms the basis for many of our high-quality products and guarantees natural quality.
Kaolin
The “white gold” from Europe’s most important deposit. We extract, calcine and refine it ourselves, e.g. for paints, varnishes and the paper industry. Highest quality, short distances, decades of experience.
Quartz
Basis for building materials, water treatment, screeds and concretes. It is also the core of our high-tech colored sands, which make surfaces durable, slip-resistant and visually appealing.
Feldspar
High-purity potassium feldspar from our own deposits. Important for glass, ceramics and special applications in medicine and packaging – always with high purity and homogeneity.
Sustainability & efficiency
We continuously optimize the use of resources. Residual materials from production are upgraded to primary raw materials for other industries. In 2020, we were awarded the German Raw Material Efficiency Prize for this sustainable strategy.
Milestones in our success story: a journey through innovation and growth
