Production units

The site has a nitric acid plant, an NPK fertilizer plant and a nitrate plant.

The plant uses the Nantes - Saint Nazaire harbor for the unloading of raw materials and loading of ships for export. The complex fertilizer plant is extremely flexible, producing more than 50 different grades annually. The plant invested in new crushers in 2003 to increase hourly rates.

Originally the nitrate unit produced ammonium nitrate fertilizer 33.5 but has been modified to produce newly developed special-grade nitrate-based fertilizers.

An aqueous ammonia unit and a CO2 storage unit were added in 2007.


Montoir has an integrated, continuous improvement management system and is ISO 9001 (quality), ISO 14001 (environment), ISO 18001 (safety) certified.

The risk based inspection system for pressurized tanks, storage vessels and pipes has also been certified by the authorities.

During the past 10 years investments have been made to improve industrial safety and to reduce the level of emissions, notably investments to reduce NPK dust emissions to air (90 percent reduction), N2O and NOx emissions. A wall has been erected around the ammonia storage unit.
