Beginning

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.

1974
- December
  
  Started development of 3-way catalyst
Pellet 3-way catalyst

Our company, which was a venture company at that time, had almost no knowledge of catalysts. Meanwhile, in response to the growing demand for purification of nitrogen oxides (NOx) in exhaust gas due to pollution problems, etc., after development setbacks, we made the first pellet catalyst in Japan in which rhodium (Rh) was added to platinum (Pt). Although there was a problem with heat resistance and erosion, the use of pellet catalysts became possible as the level of engine control technology improved.
