From production to cleanup, Ravenna is a concrete example of circular economy

It is said that Enrico Mattei strongly desired the large petrochemical area in Ravenna. Upon returning from a visit to a synthetic rubber plant in America, Eni's first ever chairman, then Ente Nazionale Idrocarburi, decided to import the technology to his country. Ravenna was selected in virtue of excellent relations with local institutions, not to mention its flat lands, port and above all, its proximity to primary material sources. This was the period of exploration activities in Emilia Romagna, with the discovery of the "Ravenna Terra" gas deposit. Upon obtaining the support of local institutions, Enrico Mattei appointed Anic for the construction of the complex. More than five thousand specialised individuals were involved at plant work sites, which were divided into "islands". After just two years, a record pace for Italy on the eve of the economic boom, Ravenna became the home for what was then the largest and most modern petrochemical site in Europe. The first bale of synthetic rubber was produced by the SBR in emulsion plant in 1957.

During the 60s, the production of PVC, acetates and fine chemicals (DMC) was also added. In 1983 Anic handed activities over to Enichem. During the Nineties a number of production facilities were transferred to third parties, including the company branch Agricoltura to Hydro Agri Italia, vinyl acetate to Vinavil and biphenols to Borregaard. In 1993 the CVM/PVC company branch was handed over to EVS. Two years later, TAS and the cement plant were handed over to the company Ambiente, whereas electric power plants and ancillary services were first transferred to Frene in 1994 and then to EniPower in 2000. In 2002 Polimeri Europa, now Versalis, purchased the production of styrenics, elastomers, olefins and intermediates from Enichem. At the same time, Syndial, now Eni Rewind, became the sole owner of all areas, internal and external to the plant, amounting to approximately 62 hectares in total. In 1997, external areas no longer used for production purposes underwent environmental cleanup, whereas the Ponticelle external area is today at the heart of a virtuous circular project re-named Ponticelle NOI - New Opportunities for Innovation, which includes environmental cleanup activities (by means of capping), as well as the implementation of an important development and and industrial requalification plan focused on sustainable development and which will transform the Ponticelle area into a green energy island. Further confirmation of the far-sightedness of the Ravenna territory, which believes in the constructive relationship with Eni.

As at 31st December 2019, € 40 million had been spent on the reclamation of the Ravenna site and is expected to spend a further € 30 million up to the completion of works an well as € 60 for the Ponticelle project.
