Sodium carbonate and bicarbonate: flagship of French industry in the Lorraine region
Located in La Madeleine in Laneuveville-devant-Nancy, in the heart of France’s Lorraine region, the Novacarb chemical plant produces and markets sodium bicarbonate and sodium carbonate.
With solid expertise acquired over the course of its 170-year history, the site offers high-quality products for demanding needs in pharmaceutical, hemodialysis, environmental, and human food markets. Novacarb benefits from direct access to its main raw materials, with salt extracted from the Lenoncourt salt concession (located in Art-sur-Meurthe, Cerville, and Lenoncourt) and limestone from the Pagny-sur-Meuse quarry.
