Venice biorefinery: the first refinery to become bio

In 2014, we opened the first biorefinery converted from a traditional refinery thanks to a proprietary patent.

The biorefinery

In 2014, we launched the world’s first bio-refinery converted from a traditional refinery. Located in Venice, the conversion was made possible by Eni’s own patented innovations. Eni's Venice bio-refinery produces HVO, or hydrogenated vegetable oil, which is added to diesel fuel to meet European and national regulatory requirements which state that an increasing proportion of fuels must be made from raw materials from renewable sources. In 2020, with an authorised capacity of 400,000 tonnes/year, it processed around 220,000 tonnes of raw materials, of which more than 25% consisted of used cooking oils, animal fats and other waste vegetable oils. From 2023 Eni will no longer use palm oil in its production processes. With the construction of the new biomass treatment lines, the entire production capacity of the EcofiningTM plant will be satisfied with biological materials from the waste and residue chains, expanding feedstock options beyond those incentivised by European and national standards, thus definitively eliminating palm oil from the production of biofuels.

In order to promote initiatives to decarbonize the aviation sector and accelerate the process of energy transition of airports, signed an agreement with SEA, the Milan Malpensa and Milan Linate airports operator, for the supply of sustainable fuels for aviation (SAF – Sustainable Aviation Fuel) and for ground handling (HVO – Hydrotreated Vegetable Oil). This initiative is in line with the agreement finalized in January 2022 with Aeroporti di Roma which launched the first supplies of pure HVO hydrogenated biofuel, produced in Eni’s biorefinery in Porto Marghera, to fuel the road vehicles for handling passengers with reduced mobility at the airport. SAF production started in October, are produced exclusively from waste and residues.

The plant is powered by certified vegetable oil and purified cooking oil

The Venice plant produces bio-diesel with EcofiningTM technology. In June 2018, a purification plant started up which allows the processing of crude instead of pre-treated vegetable oils, to increase the amount of cooking and vegetable oils and animal fats used. From 2024, a further upgrading of the plant will increase the bio-refinery processing capacity up to 560,000 tonnes per year with a total production of bio-diesel that will reach approximately 420,000 tonnes per year. The overall cost of the bio-refinery is 500 million euros, including research and other costs. It employs around 200 actual people (BP 2021-2024) and has created 200 induced jobs.
