The Lannemezan production unit
Nestled in the heart of the Midi-Pyrénées region, the Arkema plant in Lannemezan specializes in the production of hydrazine hydrate and its derivatives from hydrogen peroxide.
Located between the Atlantic Ocean and the Mediterranean Sea, halfway between Toulouse and Pau, the Lannemezan production unit was set up in 1917 by the Poudrerie Nationale de Toulouse [National Powder Factory of Toulouse]. First dedicated to the production of lime, calcium carbide, nitrogen and calcium cyanamide, in 1962, the Lannemezan plant turned to the production of hydrazine hydrate, which has since become its core business. Now part of Arkema, the Lannemezan plant is an important source of employment.
