​Omya not only selects the purest raw materials when manufacturing its product range for food, but also ensures high quality standards at its manufacturing sites.


​Omya’s natural calcium carbonate products fulfil the international standards set out in E170 and the Food Chemicals Codex. Moreover, products fulfilling EP (European Pharmacopeia) and USP (US Pharmacopeia) purity requirements are also available.
​To ensure high product quality, Omya’s products undergo a validated thermal kill step. This guarantees very low microbiological values.
Omya’s plants are GFSI (Global Food Safety Initiative) certified or have at least been audited according to ISO 22000. The applicable GFSI standards at Omya are BRC (British Retail Consortium) for its Omya Calcipur® range and FSSC 22000 for Omya-Cal®.
