Koster S.r.l. has officially inaugurated a state-of-the-art biomethane facility in San Nazzaro Sesia, Novara Province.
Built with AB Group’s advanced BIOCH4NGE 12.5 technology, the plant processes more than 60,000 tonnes of organic waste and sludge annually, producing approximately 6.4 million Sm³ of biomethane.
This renewable gas is injected directly into the national grid and used locally to fuel vehicles through an on-site refuelling station, directly supporting the decarbonisation of both the energy and transport sectors.
In addition to renewable gas, the facility generates around 50,000 tonnes of high-grade compost each year, with 95% destined for open-field agriculture.
The project demonstrates a fully integrated circular approach, turning municipal waste into clean energy and valuable agricultural resources.
“This isn’t just talk—it’s action,” said Costanzo Borda, CEO of Koster. “We are producing biomethane from waste today, and tomorrow we’ll produce hydrogen from agricultural residues. This is how we see the future: sustainable, innovative, and energy independent.”
The €25 million investment has been realised with the support of several strategic partners. AB Group provided the gas upgrading systems, while Cesaro Mac Import and Kanadevia Inova delivered the anaerobic digestion technology, including two 2,100 m³ Kompogas digesters.
For logistics, Koster’s transport division Logter has taken delivery of six low-emission IVECO S-Way trucks - four LNG and two CNG models.
Refuelling is managed via Vulcan’s VCARD network, ensuring full integration of biomethane into Koster’s operations.
Angelo Baronchelli, President of AB, commented: “This facility exemplifies how technological innovation, industrial vision and strategic collaboration can deliver real progress in the energy transition.”
