This is demonstrated, not only in our choice of natural raw materials lime, sand and water and conservation of resources, but also in our cooperation with experienced and competent partners from water treatment technology. Our CalciumSilicateHydrate (CSH) SIMPur is already successfully used as a multifunctional mineral in water treatment technologies.Sustainability and responsibility for our environment are taken literally at Cirkel.
