Omya AG is a privately held Swiss company specializing in industrial minerals and the distribution of specialty chemicals. Headquartered in Oftringen, Switzerland and founded in 1884, Omya develops and produces mineral-based materials with a core focus on calcium carbonate—both ground (GCC) and precipitated (PCC)—as well as dolomite and related mineral products. The company operates quarries and processing facilities worldwide to supply mineral fillers, functional additives, and pigment extenders.
Omya’s minerals and chemical distribution portfolio serve applications across paper and board (filling and coating), paints and coatings, plastics and rubber, construction materials, adhesives and sealants, agriculture, water treatment, and consumer goods, including food and personal care grades where regulatory-compliant. In addition to mineral products, Omya distributes complementary specialty chemicals such as binders, resins, pigments, and performance additives, providing formulation components for a broad range of industrial and life-science markets.
