Sustainability in the maintenance plants

Improving our environmental sustainability

Trenitalia has long been committed to improving its environmental sustainability including within the train maintenance processes at its industrial sites, located throughout the country.

To reduce the environmental impact of its operations, Trenitalia is developing numerous projects aimed at producing energy from renewable sources, but also at rationalising consumption and increasing energy efficiency.

Production of energy through renewable sources

In 2025 the photovoltaic systems currently active in 12 Trenitalia plants produced a quantity of green energy equal to that consumed annually by about 3,500 Italian families, thus avoiding the annual emission of about 2,900 tonnes of CO2 into the atmosphere.

But it doesn't stop there: to continue on the path towards decarbonisation, Trenitalia plans to further increase the number of plants equipped with photovoltaic systems throughout the country to 32 in 2030.

Efficiency in maintenance plants

To reduce its electricity and thermal energy consumption, Trenitalia is also committed to continuously improving the energy efficiency of its maintenance plants, thanks to specific interventions mainly targeting the lighting, heating and compressed air systems.

An extensive campaign of in-depth and targeted Energy Audits launched in 2015 (with around 80 audits conducted so far by a pool of experts) has allowed Trenitalia to identify the most suitable technical solutions to make its plants more energy efficient and sustainable.

Since 2015, 100% of the electricity purchased by Trenitalia and used in the plants has been certified as energy produced by renewable sources.

The reuse of water for industrial use

To date, Trenitalia has implemented wastewater recovery systems in four of its plants. With a view to saving water resources and therefore promoting a water circular economy, the wastewater at these sites undergoes special treatments (e.g. reverse osmosis or chlorination) and is then returned to the plants to be reused for industrial purposes.
