  • In 2011, injury rates of employees and contractors continued to follow the positive trends of previous years (down 4.5% and 22.6%, respectively).
  • In 2011, emissions of greenhouse gases NMVOC, SOX and NOX decreased due to lower sale volumes and to energy saving interventions performed in the year.
  • In 2011, the percentage of reused water was approximately 80%, barely unchanged from previous years.
  • In 2011, the sector reported a significant increase in adjusted net loss (€208 million, down €123 million) from 2010, due to higher supply costs of oil-based feedstock which were not recovered in sale prices on end markets in a context of substantial decrease in demand.
  • Sales of petrochemical products were 4,040 ktonnes, down 691 ktonnes, or 14.6%, from 2010 due to lower demand. Petrochemical production volumes were 6,245 ktonnes, decreased by 975 ktonnes, or down 13.5%, due to a decline in demand for petrochemical products in all business, with the only exception of elastomers (up 1%). In 2011, the average plant utilization rate decreased from 72.9 to 65.3 due to reduced production in a phase of economic slowdown.
  • Average unit sales prices increased by 20% from 2010 due to the positive impact of the oil price scenario (virgin naphtha prices increased by 31% from 2010).
  • In 2011, overall expenditure in R&D amounted to approximately €32 million in line with the previous year. A total of new 13 patent applications were filed.

Green Chemistry

In June 2011 Eni, through its subsidiary Polimeri Europa1, signed a cooperation agreement with Novamont SpA to convert Eni’s Porto Torres chemical plant into an innovative bio-based chemical complex to produce bio-plastics and other bio-based products (bio-lubricants and bio-additives) for which significant growth is expected in the medium/ long-term. The project will be supported by an integrated supply chain and raw materials of vegetable origin. Novamont will contribute with its technologies and skills in the bio-plastics and bio-based chemical sector. Eni will contribute to the joint entity with its Porto Torres plant, infrastructure and professional staff as well as its industry, technical engineering and commercial know-how in the petrochemical sector. In addition, Eni aims to build a biomass power plant and to carry out a number of projects for the environmental restoration and clean-up activities. Eni plans to make capital expenditures totalling approximately €1.2 billion in the 2011-2016 period to execute the above mentioned projects, directly or through the joint entity.

(1) From April 5, 2012 Polimeri Europa SpA changed its company name in Versalis.


Eni through Versalis performs activities of production and marketing of petrochemical products (basic petrochemicals and polymers), leveraging on a wide range of proprietary technologies, advanced production facilities, as well as a large and efficient retail network present in 18 European Countries. The principal objective of basic petrochemicals is granting the adequate availability of monomers (ethylene, butadiene and benzene) covering the needs of further production processes: in particular olefins production is strictly linked with the polyethylene and elastomers business, aromatics grant the benzene availability necessary to produce intermediate products used in the production of resins, artificial fibres and polystyrene. In polymers business Versalis is one of the most relevant European producers of elastomers, where it is present in almost all the relevant sectors (in particular the automotive industry), polystyrene and polyethylene, whose most relevant use is in flexible packaging.
