The business group that is known as Sargadelos originates from 1947 when a small factory was created at the Castro of Samoedo in Sada, A Coruña. This factory was intended to experiment with kaolin from the Sargadelos sites that were still in operation. The spirit that gave life to this project was to recuperate the activity which had been born in Galicia 200 years ago with the creaton of an industrial complex that demonstrated modern production methods making the most and adding value to the natural resources in the same area.
