Limestone is an essential raw material
Ground Calcium Carbonate
The paper and cardboard industries use lime-based coating pigments and fillers such as GCC (Ground Calcium Carbonate). GCC is made from concentrated and fine-ground calcium carbonate and used to make fine paper, cardboard packaging and pulp-based paper.
The calcite for GCC is manufactured in Lappeenranta, Finland, where the local marble is extremely white. The producer of GCC in Lappeenranta is Nordkalk's subsidiary Suomen Karbonaatti Oy.
Precipitated Calcium Carbonate
PCC (Precipitated Calcium Carbonate) is made from quicklime. It is mainly used as filler in fine paper such as copy paper, in which brightness and opacity are important qualities.
