CalciTech has developed a process for transforming waste minerals into a new high value material which can be used in large, stable end markets such as paper, polymers, sealants, paints, inks, food and pharmaceuticals. These markets are also looking to improve the sustainability of their processes by using raw materials that have been recycled and have a lower carbon footprint (eco-minerals).The new material brings additional benefits that are cost effective: higher filler loadings that reduce the amount of costly polymers, reduced use of titanium dioxide, reduced use of imported specialist clays and ground marble and increased process efficiencies.

The new material, Synthetic Calcium Carbonate (SCC), is produced using a patented process from lime (calcium oxide or hydroxide) and carbon dioxide. The SCC is exceptionally pure and of a unique particle size and shape which bring excellent rheological characteristics as well as the benefits of higher brightness, whiteness, opacity and gloss over existing forms of calcium carbonate. These qualities enable SCC to compete with high priced white minerals such as titanium dioxide, aluminium silicate, calcined clay, and specialist kaolins. This positions SCC above commodity minerals such as Ground Calcium Carbonate (GCC) and Precipitated Calcium Carbonate (PCC) and kaolin.
