First Spanish company to apply electricity in the chlorine manufacturing process
A pioneer in the chemical sector
After 125 years of production activity, in 2023 the factory in Flix (Tarragona) closed its last remaining plant.
In 1899, it was the first in Spain and the third in Europe to carry out the great technological change experienced by the traditional chemical industry by applying electricity to the chlorine manufacturing process. In December 2017, the factory closed the electrolysis plant with mercury technology, in compliance with the Chlorine-alkali BREF.
The plant is currently undergoing demolition work and soil treatment.
