The Syracuse petrochemical hub was created as part of the industrialisation plan for southern Italy after the Second World War. This plan was implemented in eastern Sicily by setting up plants for refining oil and processing its derivatives. Since its foundation in 1956, the Priolo Gargallo industrial plant has expanded significantly in the oil and chemical sectors, changing hands many times. In 1991, following a transaction with Enimont, the Eni group entered the site through Enichem, which acquired the base and intermediate chemical plants as well as the refining facilities from Montedison. A state of environmental emergency was declared during this decade (1990’s) and the site was classified as one of National Priority in 1998. The Priolo site covers 5,815 hectares of land and 10,815 hectares offshore, including the port of Augusta, an important crossroads for commercial shipping in the Mediterranean. Since 2002, Eni's subsidiaries have carried out emergency safety measures and have designed, defined, implemented and managed systems to eliminate contamination. These operations are in compliance with the projects and protocols approved by the Ministry of the Environment and by control bodies to further scale up the reuse of treated groundwater, the adoption of innovative and environmentally friendly technologies and the regeneration of the areas owned by the group.

Our activities in Priolo
Eni Rewind inherited approximately 300 hectares of Enichem property and has been carrying out emergency safety measures, as well as soil and groundwater remediation since 2002, in compliance with the decrees issued by the Ministry of the Environment. The Unitary Monitoring Protocol (UMP) of groundwater within the multi-company site was approved by the control bodies and has been active since 2016. It verifies the status and progress of the reclamation, as well as the effectiveness and efficiency of the systems in place. The company has completed the demolition of the Dichlorethane (DL1), Alkaline Carbonates (CS9) and Propylene Oxide (PO) plants, while the chlor-alkali plant is awaiting authorisation.
