Veolia and Solvay, through their joint subsidiary Resolest, have inaugurated a new advanced recycling unit at the Rosières-aux-Salines facility in Meurthe-et-Moselle, France. This new unit significantly increases the site’s capacity, allowing it to process and recover up to 50% more industrial flue gas treatment residues annually.
This milestone marks a critical step forward in Resolest’s development and aligns with the strategic momentum initiated in 2024, further advancing the region’s commitment to a sustainable, circular economy.
Transforming Waste into Resources
For more than two decades, the Rosières-aux-Salines site has been at the forefront of industrial residue recovery. The facility specializes in extracting salt from flue gas treatment residues that result from sodium bicarbonate-based processes. This recovered salt is then purified into brine and used by Solvay’s nearby Dombasle plant in the production of sodium carbonate, a key industrial chemical.
As per the company press release, the circular process is both innovative and localized. Driven by the combined expertise of Solvay and Veolia, it converts waste into valuable raw materials. This helps conserve natural resources and reduce environmental impact.
Leadership Perspectives
Jean-Michel Frada, Director of Resolest, stated, “For over twenty years, Resolest has pioneered the recovery of materials once considered non-recoverable. This expansion strengthens our capacity to produce reusable industrial salts and contribute to the preservation of natural resources.”
Étienne Galan, Solvay echoed, “At Solvay, we believe in the circular economy as a path to a more sustainable future. This expansion with Veolia is a concrete example of our commitment to turning challenges into opportunities.”
Jean-François Nogrette, Veolia, remarked, “The circular industry we are building with Solvay in the Grand Est region is not just a solution to environmental challenges—it’s a catalyst for innovation, resource efficiency, and economic sovereignty. Veolia is proud to bring its full expertise to this mission.”
