FAQs
Ground calcium carbonate is a natural and renewable raw material that is compatible with standard recycling methods. Since calcium carbonate is a naturally occurring mineral, it does not involve any energy consuming chemical reaction, giving it a substantially lower carbon footprint than fiber production.
Omya calcium carbonate fillers and coating pigments are used to substitute a proportion of the wood fiber in paperboard, as well as reducing the need for latex in the coating formulation. This not only reduces the demand for fiber and latex but saves energy by improving dewatering and lowering the drying time.
Calcium carbonate has a low carbon footprint and is a natural, renewable material, so substitution of fiber with calcium carbonate reduces the overall carbon footprint of the paperboard.
The use of calcium carbonate as either mineral filler or coating pigments for paperboard production typically results in a smoother paper surface.
This improves the printability of the paper, but more importantly for the manufacturer, it increases machine runability and reduces wear and tear.
Omya’s calcium carbonate fillers and coatings also help with the retention of other additives and fine particles during the paperboard manufacturing process, resulting in a more consistent product.
