The Conti Vecchi saltworks are located in one of Europe's most important wetlands
and were commissioned back in 1931 for the production of salt, magnesium sulphate
and magnesium chloride, when Luigi Conti Vecchi was granted a concession in 1921 by
Today the company Società Ing. Luigi Conti Vecchi (100% owned by Eni Rewind) manages both the salt planes, which cover approximately 2,700 hectares, located in the municipalities of Assemini, Capoterra and Cagliari, as well as the plant where sodium carbonate, hydrochloric acid and hypochlorite is produced.
In December 2014 Eni's environmental company handed over the chlorine-sodium and
derivatives branch of the company to Ing. Luigi Conti Vecchi which until them managed
the salt works alone and became part of Eni in 1984. In April 2013 the site requalification
plan had already begun, with a total investment of approximately 60 million euros,
also in accordance with provisions set forth in the trade union agreement signed on
14th February 2013 which led to the plant ceasing dichloroethane production.
In order to enhance the site's productive vocation, the following was carried out:
reduction of the old chlorine-sodium plant and modernisation of the plant which also uses salt from the salt planes in an electrolysis process in latest generation bipolar membrane cells to produce 30% soda, hydrochloric acid and sodium hypochlorite;
allocation of part of salt for food grade use by means of a new refining and bagging plant;
automation of production plant management;
Plant requalification has also enabled the consolidation and development of the reference position in Italy for the production and sale of electrolytic products, thanks to the availability of logistics hub in Priolo, Vasto (soon to open) and Livorno, as well as in Assemini.
