Kemira is stepping up the production of calcium sulfate pigment in Siilinjärvi, Finland

25-Jun-2007
Kemira is increasing its production of calcium sulfate pigments in Siilinjärvi by 25,000 tons to 175,000 tons. The investment is worth of EUR 4.9 million. The project includes a new production line and a wet-refining unit in Siilinjärvi and pilot-scale research equipment at the Espoo research center in Finland. Kemira's paper pigments production plants are located in Finland, Siilinjärvi and in Spain, Besalu. The company's new filler and coating pigment solutions have been developed for the manufacture of high-quality magazine papers. The new pigment technology enables paper industry customers to save in raw materials consumption and improve efficiency. The new calcium sulfate crystallization technology is opening up export markets from Finland to the paper industry in Continental Europe and in Scandinavia. At present, Kemira delivers the product in slurry form, but thanks to the new technology the product can be delivered in the future in dry format to the customers far away. Moreover, the use of new gypsum raw materials sources is enabling expansion of the present production volume.
