Assemini's story began in the 1960s when the site on the outskirts of Cagliari was chosen as part of the Sardinia Revival Plan to regenerate the economy in the south of the island. Petrochemical activities were launched with eight integrated companies operating in inorganic and organic chemicals, these were later merged into Rumianca Sud and then SIR. In this context, the adjacent salt pans provided salt for the chlorine-dichlorethane industry. Eni (in particular, Enichem) took over the plant in the early 1980s, as part of the government's industrial rescue operation; among the transferred assets was the Ing. Luigi Conti Vecchi company, along with the concession of the salt pans. Enichem started a regeneration process which peaked in 1986 with the introduction of a more sustainable membrane technology, which replaced the previous mercury-based one, for caustic soda production. The Assemini site, which integrated the chlorine, vinyl chlorine and polyvinylchlorine supply chain, was downsized to only include caustic soda and dichlorethane production. Afterwards Syndial (renaming of Enichem, now Eni Rewind), following Ineos’s exit from the Italian market, Safi’s Group acquisition and the subsequent commissioner management, in 2013 halted the dichlorethane plant and at the same time launched a productive requalification plan involving salt and caustic soda production through the controlled Ing. Luigi Conti Vecchi company. In 2021, Eni Rewind transferred to Società Chimica Assemini the caustic soda assets, as well as the water treatment and recovery plants in 2023. Italkali, as operator in the salt industry, acquired the shares of ILCV in 2022, taking over the management of the Conti Vecchi salt pans.
