Technology
For decades, chalk has been used as a filler to improve plastic properties. However, chalk must be mined.
We use kukermite – a production residue already stored in landfills, that offers similar or even superior performance.
The Game-Changer: Kukermite
Kukermite is a mineral residue produced from oil shale. Instead of being discarded in landfills, it is carefully processed and refined to enhance its properties. This results in a filler material that rivals traditional chalk in performance. Supporting data can be found in downloadable documents.
Innovation Backed by Science
Our technology has been perfected over 16 years of research.
Developed in collaboration with Tallinn University of Technology (TalTech).
