The Porto Torres petrochemical hub, one of the largest in Italy, was set up in 1962 by entrepreneur Nino Rovelli’s SIR - Società Italiana Resine (Italian Resin Company) for the large-scale production of phenol, with funding from the Sardinia Rebirth Plan. In later years, olefins, aromatics, chlorinated derivatives, intermediates and synthetic rubbers were added to the production. With the crisis in the chemical sector, in the early 1980s, activities were legally transferred to Eni, then a state-owned company, through Enichem, which reorganised and updated them by putting in place new technologies. Between 1994 and 1995, Enichem transferred its fine chemicals production lines to the European Vynils Corporation and Condea Augusta. In 2003, when Enichem changed its name to Syndial (Eni Rewind), the production plants (for styrenes, elastomers and polyethylene) passed to Polimeri Europa (Versalis). Today, Eni Rewind owns around 1,200 hectares of land, of which less than 10% is subject to environmental activities, and is working on the authorised remediation projects of soil and groundwater using sustainable and innovative solutions, such as the construction of a multifunctional platform for on-site soil treatment.

Our activities in Porto Torres
The first environmental activities at the site date back to 2001, with permanent safety measures, characterisation and the construction of the monitoring network and groundwater treatment plants. In 2010, on approval of the risk analysis, an environmental action plan was defined that takes into account the commitments made by Eni in the Green Chemicals Protocol. The company has also completed the demolition of almost all the installations and buildings outside the compound, with the exception of sixteen tanks, their interconnections and the Tripolyphosphate building.
