Major boost as 500 million deal accelerates Sannazzaro biorefinery project growth
The Sannazzaro biorefinery project has taken a decisive step forward following a €500 million financing agreement between the European Investment Bank and Eni
This long-term loan, structured over 15 years, will support the transformation of part of the Sannazzaro de’ Burgondi refinery in northern Italy into a modern biorefinery focused on sustainable fuel production.
This development marks another milestone in Europe’s broader decarbonisation strategy, reinforcing the role of advanced biofuels in reducing emissions across multiple transport sectors.
Strategic transformation of a traditional refinery
At the core of the Sannazzaro biorefinery project is the conversion of the refinery’s hydrocracking unit using advanced Ecofining technology. This proprietary process enables the production of hydrotreated vegetable oil, a renewable biofuel derived from waste-based feedstocks such as used cooking oils, animal fats and agri-food residues.
In parallel, a dedicated pre-treatment plant will be constructed to process these raw materials efficiently. This integrated approach ensures that waste streams are transformed into high-value energy products, supporting circular economy principles while reducing reliance on fossil fuels.
Expanding production of sustainable fuels
From 2028, the Sannazzaro biorefinery project is expected to deliver an annual production capacity of approximately 550,000 tonnes of biofuels. This includes both HVO diesel and sustainable aviation fuel, two critical components in the transition toward lower-carbon mobility.
HVO biofuels are already widely used due to their compatibility with existing engines and infrastructure. Meanwhile, SAF is emerging as the only viable large-scale solution for reducing emissions in aviation, a sector that remains difficult to decarbonise through electrification alone.
The growing demand for SAF, driven by European regulations such as ReFuelEU Aviation, strengthens the long-term viability of the Sannazzaro biorefinery project.
Strengthening Europe’s energy security
Beyond environmental benefits, the Sannazzaro biorefinery project plays a strategic role in enhancing energy security across Italy and the European Union. By increasing domestic production of renewable fuels, the project reduces dependence on imported fossil resources and diversifies the energy mix.
This aligns closely with the objectives of the REPowerEU plan, which aims to accelerate the transition to clean energy while ensuring stable and secure supply chains.
The project also builds on existing infrastructure, allowing for a more efficient conversion process and minimizing additional land use or environmental disruption.
A broader industrial strategy from Eni
The Sannazzaro biorefinery project is part of a wider strategy by Eni and its subsidiary Enilive to scale up biofuel production significantly. The company aims to reach a total capacity of 5 million tonnes by 2030, including over 2 million tonnes dedicated to sustainable aviation fuel.
Existing biorefineries in Venice and Gela already contribute to this goal, while new facilities are under development in Italy and internationally. Upcoming projects include plants in Livorno, Malaysia, South Korea and Sicily, demonstrating a global expansion strategy focused on renewable fuels.
This coordinated approach highlights how the Sannazzaro biorefinery project fits into a larger industrial ecosystem designed to support the energy transition.
Immediate impact on emissions reduction
One of the key advantages of the Sannazzaro biorefinery project is its ability to deliver immediate emissions reductions. Unlike emerging technologies that require new infrastructure, HVO biofuels can be used within current distribution systems and vehicle fleets.
This makes them a practical solution for decarbonising road transport, maritime logistics, rail networks and even aviation. As a result, the project offers both short-term environmental benefits and long-term scalability.
According to international energy projections, biofuels are expected to increase their share in global transport energy consumption significantly in the coming decades, reinforcing the importance of initiatives like the Sannazzaro biorefinery project.
Financial and institutional backing
The involvement of the European Investment Bank underscores the strategic importance of the Sannazzaro biorefinery project. As one of the largest multilateral lenders globally, the EIB plays a key role in financing projects that align with European policy priorities, particularly in climate action and sustainable development.
This investment follows a similar financing agreement for the conversion of Eni’s Livorno refinery, indicating a consistent commitment to supporting industrial transformation within the energy sector.
The collaboration between public financial institutions and private energy companies is essential to scale up technologies that can deliver meaningful environmental impact.
Supporting circular economy and innovation
Another critical aspect of the Sannazzaro biorefinery project is its contribution to the circular economy. By using waste materials as feedstock, the project reduces environmental pressure while creating new value chains from previously discarded resources.
Eni’s investment in advanced technologies such as Ecofining, combined with its broader research initiatives in areas like carbon capture and supercomputing, positions the company at the forefront of innovation in the energy sector.
This technological edge enhances the competitiveness and sustainability of the Sannazzaro biorefinery project over the long term.
Outlook for the European energy transition
The Sannazzaro biorefinery project reflects a broader shift in how Europe is approaching the energy transition. Rather than relying on a single solution, the strategy increasingly involves a diversified portfolio of technologies, including renewables, biofuels and advanced industrial processes.
As regulatory frameworks tighten and demand for low-carbon fuels grows, projects like this will become central to achieving climate targets while maintaining economic resilience.
In this context, the Sannazzaro biorefinery project stands out as a concrete example of how industrial transformation, financial support and technological innovation can converge to accelerate the transition toward a more sustainable energy future.
