Making life better with natural minerals 

For over 140 years, Omya has been using natural minerals to improve life for current and future generations. 

Since our company was founded in 1884, Omya has focused on the use of natural minerals to solve the challenges society faces.

Calcium carbonate in the form of marble, limestone, or chalk is the basis of many of our products. Our detailed understanding of the chemistry of these raw materials has led to innovations in processing, formulations, and surface treatments.

Calcium carbonate – a sustainable resource with low carbon footprint

Calcium carbonates, such as limestone, marble and chalk, are natural and renewable as defined by ISO 14021. Nearly 4% of the Earth’s crust is composed of forms of calcium carbonate, one of the most common raw materials in nature. It is continuously replenished by natural cycles in rivers, lakes, and oceans or formed as minerals, for example, from shells or skeletons.

 

Because of this, renewing calcium carbonate does not involve any energy-consuming chemical reaction, leaving the carbon footprint substantially lower than that of many of the raw materials it replaces. As a bio-mineralized or naturally produced resource, calcium carbonate is constantly renewed by natural processes, ensuring that reserves are available for many future generations. The replenishment rate exceeds the consumption rate, meeting the criteria for a renewable material.
