Imerys enters into exclusive negotiations to acquire Chemviron’s European diatomite and perlite business

Imerys announces today it has entered into exclusive negotiations with Chemviron, a subsidiary of Calgon Carbon Corporation, to acquire its European diatomite and perlite business.

Through this acquisition, Imerys would extend and complement its European footprint in diatomite and perlite and broaden its Filtration and Life Sciences product portfolio, to better serve its customers in the food, beverage, filtration and pharmaceutical markets.

Imerys would acquire three high-quality mining and industrial assets in France and in Italy. In 2023, this business generated approximately €50 million in revenue with around 130 employees.

Alessandro Dazza, CEO of Imerys, said: ”Imerys aims to further strengthen its core industrial minerals business. This transaction would be a perfect fit and a unique opportunity to expand our offering of natural solutions for consumer goods. Our clients are set to benefit from our expanded product portfolio, broader market reach and innovation capabilities.”

The transaction, which is subject to customary closing conditions, including the information and consultation of employee representatives, is expected to be completed by the end of the year.
