Milano, 22 June 2026: Andion CH4 Renewables SAS (“Andion CH4”) has signed a binding agreement, subject to customary closing conditions, to acquire a majority of the share capital of the Agromet biomethane plant from Greenthesis.

The Agromet Barbianello plant, located in the municipality of Barbianello, in the province of Pavia, Lombardy, currently operates with an installed capacity of approximately 42 GWh and will complete its conversion from biogas to biomethane in July 2026. The acquisition further strengthens Andion’s portfolio of renewable energy infrastructure assets in Europe. The project converts organic waste streams into dispatchable, low-carbon energy, contributing to national decarbonisation targets while also strengthening local energy security.

Following completion of the acquisition, the plant will be owned and operated by Andion and will apply a proven anaerobic digestion technology process to transform agricultural residues into high-quality renewable biomethane, compliant with Decree No. 240 of 15 September 2022, commonly known as the Italian Biomethane Decree DM 2022. Through the production of biomethane, methane that would otherwise be released into the atmosphere from the spreading of untreated slurry and manure in agriculture is captured and converted into a renewable fuel that replaces fossil energy sources, thereby generating significant and measurable reductions in greenhouse gas emissions across the full lifecycle.

ESG principles are embedded across the full lifecycle, from initial design to long-term operation. The project will also prioritise environmental performance, safe and efficient plant management, and transparent reporting, while working closely with local stakeholders, suppliers, and farming communities to generate long-term regional benefits.

This new facility represents another step in Andion’s strategy to quickly scale up a platform of high-quality biomethane assets across attractive European markets and to build long-term renewable energy infrastructure that contributes to a low-carbon, resource-efficient energy system.

Studio Legale De Berti Jacchia Franchini Forlani acted as legal counsel to Andion CH4. Chiomenti acted as legal counsellors to Greenthesis.
