Veolia has inaugurated a new composting and biomass plant in Fuentes de Ebro, Zaragoza in Spain, combining organic waste processing with the production of solid fuels from forestry and agricultural residues in a single integrated facility.

The opening represents one of the most significant investments in bioenergy infrastructure in the Aragón region in recent years, and a concrete expression of the French environmental services giant’s GreenUp strategy, which targets 8 GW of installed bioenergy capacity globally by 2030.

Two lines, one integrated model

The facility operates across two complementary lines. The composting plant can process 27,000 tonnes of organic waste per year across two treatment streams: one handling sewage sludge suitable for agricultural application under Spanish and EU regulatory frameworks, and one processing waste destined for fertiliser manufacturing in compliance with EU Regulation 2019/1009.

The biomass processing platform handles up to 15,000 tonnes per year of forestry and agricultural residues, classifying and shredding material to produce wood chips and pellets for industrial boilers and district heating networks. Total processing capacity exceeds 50,000 tonnes per year.

Public-private funding model

The project received public funding from the EU and the Department of the Presidency, Economy and Justice of the Government of Aragón, with grants covering 40% of equipment costs for the fertiliser refining and biomass processing lines. The public-private funding model — combining Veolia’s private capital with EU and regional government support — is precisely the kind of structure both the EU and the Government of Aragón have been promoting as a vehicle for accelerating the transition to a more circular, lower-carbon economy. For the region, the plant creates skilled local employment in emerging sectors and strengthens Aragón’s credentials as a destination for sustainable investment.

Miguel Ruiz-Gálvez, director of Veolia Biomass, said the facility reflects the company’s GreenUp strategy of generating value from local resources while supporting the circular economy and regional decarbonisation.

‘We are committed to models capable of generating value from local resources, while at the same time driving the circular economy and the decarbonisation of the region,’ he said.

A site with wider ambitions

The Fuentes de Ebro site also sits in a broader context of renewable energy ambition in Aragón. In 2024, US company Raven announced plans to develop a €50 million sustainable hydrogen hub at the same location — what would have been the first European hub converting organic waste into sustainable hydrogen using Steam CO2 Reformer technology, with an estimated production capacity of more than 1.8 million kilograms of hydrogen annually.

While that project is at a different stage of development, the clustering of complementary renewable energy initiatives at a single site in Fuentes de Ebro reflects a deliberate effort to build an integrated circular economy hub capable of handling the region’s organic waste streams across multiple value chains.

Growing Spanish biomass portfolio

Veolia’s biomass and bioenergy operations in Spain have been growing steadily. The company previously inaugurated a 12.5 MW biomass district heating system in Móstoles, in the Madrid region, through a partnership with Móstoles Ecoenergia, providing heat to 3,000 homes with an expansion planned to reach a further 4,000 households.

The Fuentes de Ebro facility adds a different dimension to the portfolio. Rather than generating heat directly, it processes the raw materials that feed industrial and district heating systems elsewhere in the supply chain, positioning Veolia as a supplier of solid biomass fuels as well as an operator of energy infrastructure.

GreenUp’s bioenergy drive

The investment is consistent with the direction of Veolia’s GreenUp programme, launched in February 2024 as a 2024–2027 strategic plan targeting accelerated growth across waste, water and energy. Bioenergy forms one of the plan’s designated booster businesses alongside hazardous waste and energy flexibility: segments that Veolia has identified as delivering above-average growth and margin contribution.

In the first half of last year, Veolia’s booster businesses grew by 6.6% on a like-for-like basis, with Spain cited among the markets delivering strong commercial activity in energy. The group reported record full-year 2025 revenues of €44.4 billion and an EBITDA of €7.05 billion, exceeding guidance and achieving its GreenUp return on capital target two years ahead of schedule.

Turning cost into value

The Fuentes de Ebro plant exemplifies a broader shift in how large waste management and environmental services companies are approaching biomass. Rather than treating forestry and agricultural residues purely as a disposal or processing challenge, the facility valorises them as a feedstock for solid fuels — wood chips and pellets — with defined end markets in industrial boilers and district heating networks. The composting lines follow the same logic: sewage sludge that would otherwise require costly disposal becomes an agricultural input, and organic waste becomes a compliant EU-standard fertiliser product. The result is a facility that generates revenue from material streams that previously generated cost.

Aragón’s renewable energy context

Aragón’s broader renewable energy ambitions provide a supportive context. The region has attracted substantial wind and solar investment in recent years and has been building its credentials in renewable gas, with a number of biomethane projects in development across the wider Ebro Valley.

The combination of agricultural residues, strong solar and wind resources and an improving regulatory framework for circular economy infrastructure has made Aragón increasingly attractive for the kind of integrated investment that Veolia’s Fuentes de Ebro plant represents.

For Veolia, it is one piece of a European bioenergy mosaic that the company is assembling plant by plant across multiple countries, with a clear strategic logic: use locally available organic material, apply proven processing technology, secure public co-funding where available, and create assets that serve both energy and agricultural markets simultaneously.
