Imerys has announced the acquisition of Chemviron’s diatomite and perlite assets in France and Italy, following exclusive negotiations initiated in April 2024. 

The acquisition includes three sites employing a total of 130 people: two diatomite deposits and processing plants located in Saint-Bauzile (Ardèche) and Riom-ès-Montagnes (Cantal), France, as well as a perlite processing plant in Foggia (Puglia), Italy.

This strategic move expands Imerys’ European footprint in diatomite and perlite, and enhances the company’s ability to serve its customers from the food, beverage, filtration, and pharmaceutical sectors. Notably, the acquisition will round out Imerys’ portfolio of advanced solutions, including high-permeability filtration aids tailored to sweetener, gelatin, and enzyme applications, as well as high-performance grades for beverage filtration.
