The industrial history of the Crotone site began in the 1930s with the productions by the companies Pertusola Sud (former Pertusola area) and Ammonia Meridionale (former Fosfotec and former Agricoltura areas), the latter of which was subsequently transferred to Montecatini and then merged into Montedison in 1966. In the early 1990s the facilities, following Eni’s acquisition and rescue operations as a state-owned company, were transferred to Enichem, which managed the closure of the plants and initiated the environmental operations through safety and remediation interventions. In 2001, the Ministry of Environment identified by decree the site of Crotone-Cassano-Cerchiara as being one of national interest, including within the perimeter not only the internal areas occupied by the decommissioned plants, but also the former Pertusola and Fosfotec landfills.
In June 2023, as part of the procedure in compliance with article 244 of the the Italian Consolidated Environmental Act for the areas of former Montedison origin, the Province of Crotone issued the Ordinance with which it identified Edison as approximately 95% responsible for the contamination of the former Agricoltura, Fosfotec and Sasol areas, and as 100% responsible for the former Fosfotec landfill. Eni Rewind was identified as responsible only for the marginal residual share, due to the years that passed since the establishment of Enimont in 1989 and the decommissioning of the former Montedison plants, which for the main part occurred before 1992.
