Assemini's story began in the 1960s when the site in Macchiareddu, 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. The adjacent salt pans of the Ing. Luigi Conti Vecchi company provided salt for the chlorine-dichlorethane industry. Eni took over the plant and the salt works in the early 1980s, through Enichem, as part of the government's industrial rescue operation. Enichem started a gradual downsizing process, introduced the first plant in Italy using membrane technology for the production of caustic soda and carried out the first environmental measures. The plant was sold to an industry player in 2021. Environmental remediation and historical natural regeneration are now the drivers of Eni Rewind's strategy for Assemini, which is part of the Sulcis Iglesiente Guspinese Site of National Priority identified in 2001.
Our activities in Assemini
Environmental remediation activities in Assemini cover the areas known as: “Plants”, “Island 5”, “External”, “former Rumianca landfill” and “Coastal Deposit”, as well as the Is Campus area owned by the CACIP Consortium. The company is also carrying out remediation activities in the Radice Pontile area which is under municipal jurisdiction. Eni Rewind manages the groundwater remediation in different ways for each area, taking the specific nature of the contaminants into account. There are many pump and treat and groundwater extraction systems, both on- and off-site, as well as a groundwater treatment plant with a capacity of 180 m3/h.
