Websites and locations

The Arkema platform in Genay is made up of a production unit and an R&D center. These two entities work together to optimize the manufacturing of rheological additives, used in water-based formulations, in particular for paint, paper, and detergents.

The platform in Genay was created in 1971. Twenty years later, it was fully integrated into the Swiss group OMYA, which is still one of our privileged customers to this day. In 1996, the site acquired a new dispersing agent manufacturing workshop.

The site in Genay became a full Arkema subsidiary in October 2007, five years before increasing its thickening agent production capacity through debottlenecking. The 12 hectares of the  platform are located in Genay, north of Lyon, in the dynamic Rhône-Alpes region.

The Genay production unit

With a total workforce of between 230 and 250 people, the platform in Genay exports 70 to 100 kt of finished products, 90% of which are for international markets.

The Genay site celebrates its 50th anniversary

All of Genay's employees gathered to celebrate the 50th anniversary of their factory for a convivial moment.

It was also an opportunity to remember the path taken by the site, which opened in December 1971 as a local additives plant for the paper industry. Today being the Arkema’s core expertise Center in Rheology and Specialty Additive, the extended reach of the activity across the world includes five industrial plants and four R&D and application centers.

“Fifty years of continuous growth is an extraordinary achievement. Throughout this time, the Additive business has expanded significantly and currently has many new technology innovations and market opportunities in sustainable development,” said Laurent Peyronneau, Global President Coating Additives. “We thank everyone who has been part of this journey to establish our Additive business as a global leader in the market.”

Under the provisions of decree No. 2019–15 of January 8, 2019, aimed, in particular, at eliminating the differences in compensation between men and women, the Arkema site of Genay, with more than 240 employees, achieved a result of 85 out of 100 for the reference year 2023.
