The main industry in TORREVIEJA as such is what is popularly known as Las Salinas, the exploitation of the salt lagoons of Torrevieja and La Mata, which have a polygonal shape and an extension of 1,400 hectares from which the salt is extracted and then exported to many different parts of the world, an activity that started back in the 18th century.

The salt lagoons of TORREVIEJA are the most important in Europe and the second on a worldwide scale. The richness of the salt extracted from the lagoons offers the possibility of getting different chemical products from them, as well as diverse types of salt with different utilities, such as the melting of the ice formed in the coldest areas of Europe. The production of salt in the TORREVIEJA lagoons reaches one million tons.

The United States as well as other American countries are the main markets which receive the salt from TORREVIEJA, followed by the Nordic countries and Europe in general.
