In 1967, when exhaust gas purification technology did not yet exist. Cataler was established for the purpose of developing and manufacturing exhaust gas purification catalysts. Soon, Cataler moved headquarters to its current location (Chihama, Kakegawa City) and was entrusted by Toyota Motor Corporation with the R&D of catalysts. We embarked on research on 3-way catalysts, and the practical application of new technologies.
