At the end of the 1990s, Považská cementáreň, a. s. developed a new patented ecotechnology SIDEROX. SIDEROX modifies and activates the by-product to an effective reducing additive in cement to reduce the water-soluble CrVI below 2 ppm. The well-known multi-award-winning CHROMATMIN cement is the result of an innovative approach with a benefit of health protection for the whole society, and especially for building industry workers.

The importance of this investment is also evidenced by the granting of the European patent for the "Method of production of low chromium cement using the technology developed by Považská cementáreň, a.s., Ladce" in 2005. Thanks to the development of the new technology, the company is not directly dependent on suppliers of reducing additives and thus it is able to significantly reduce its costs.
