Biomethane: €40 Million investment by BTS DevCo and Eiffel Investment Group for the conversion of two plants in Italy

Affi (VR),22 July 2025 – With a total investment of approximately €40 million, BTS DevCo – the development company of the BTS Group – and Eiffel Investment Group announce the acquisition of two existing biogas plants, located in the municipalities of Tromello and Garlasco (Province of Pavia), for conversion to biomethane production. The initiative is part of Italy’s National Recovery and Resilience Plan (PNRR) and contributes to the targets set by the Italian Biogas Consortium (CIB) and the National Integrated Energy and Climate Plan (PNIEC), which aim to reach an annual production of 5 billion cubic meters of biomethane by 2030.

Once converted, the two plants will produce a total of 1,500 Sm³/h of biomethane, resulting in an estimated reduction of approximately 27,400 tons of CO₂ equivalent per year — equivalent to the amount absorbed by over 900,000 mature trees*. The biomass processing will also generate around 97,000 tons per year of organic fertilizer, further supporting a virtuous circular economy model. Biomass supply will involve approximately 11 local agricultural and livestock farms, using animal effluents, by-products, and agricultural biomass. Commissioning of the plants is scheduled for June 2026. Both projects, partially funded by the PNRR, are part of the Green One pipeline — the platform through which BTS DevCo and Eiffel Investment Group invest in biomethane production in Italy and across Europe. The platform benefits from the technical expertise of BTS Biogas, a leading international operator in the sector, and from the support of Eiffel Investment Group through Eiffel Gaz Vert, its dedicated biogas investment fund.

The conversion of existing plants proves to be a sustainable solution from every perspective: it extends the operational life of infrastructure, reduces the need for new construction, minimizes land use, and optimizes both public and private investments.

“We are proud to announce these new acquisitions, which bring us closer to the target we set for ourselves,” said Franco Lusuriello, CEO of BTS Group “These projects represent a further step forward in the implementation of our group’s investment strategy and, more importantly, reinforce our active role in the energy transition. Biomethane is a strategic resource for decarbonization and energy independence, and our daily commitment is to contribute — through expertise and innovation — to shaping the path toward a more sustainable future.”

“As European investors in the energy transition sector, we are proud to support the growth of biomethane in Italy,” said Julien Bruyneel, Director within the Green Molecules team at Eiffel Investment Group. “These projects perfectly reflect our vision: to support, together with strong partners like BTS, the development of sustainable infrastructure with high environmental, economic, and territorial impact. Italy is a key country in our European biogas strategy, and we remain strongly committed to these projects.”

In detail: the Tromello plant – operated by AGRICERERE S.r.l. – will be converted to produce 750 Sm³/h of biomethane, equal to approximately 6.4 million Sm³ per year. The CO₂ savings will amount to approximately 13,700 tons of CO₂ equivalent annually, with an emissions reduction efficiency of about 80%. Over 52,000 tons of animal and plant-based biomass will be processed each year, resulting in the production of approximately 48,500 tons of organic fertilizer. The Garlasco plant, operated by AGRISORSE S.r.l., will have identical technical characteristics, with the same production capacity and benefits in terms of emissions reduction and digestate valorization.
