Stable Supply of Urea and Suppression of Air Pollutants

Protect the richness of the sea and the land

High-grade aqueous urea, with urea as the main component, is used as a reactant to deoxidize a nitrogen compound (nitrous oxide; NOx).
We are also handling urea to be used in fertilizer, industry, automobiles, ships, and more, and we have a top share in Japan. By deoxidizing the nitrogen compound in the exhaust of diesel automobiles such as large trucks and large buses, we are contributing to preventing the release of greenhouse gases into the atmosphere.

Particle boards to be used as the base layers of buildings and floors are made by compressing bonded recycled wood chips. Some of these released formaldehyde and could cause sick house syndrome.
Now, resins including urea are used as the bond to reduce the release of formaldehyde, and we supply urea to particle board manufacturers.
