Actarus Renewables and Eren Industries Secure €355 Million Financing to Advance the Next Phase of One of Europe’s Largest Biomethane Platforms

Rome, 4 August 2026 – Following the successful development of the first cluster of biomethane plants, Eren Industries and Actarus Renewables have launched the next phase of the Retina Renewable Natural Gas (RNG) platform through the construction of a second cluster of greenfield biomethane and nitrate removal plants in Southern Italy.

Retina SCA, who led the origination of the projects, Actarus Renewables and Eren Industries partnered to underwrite the equity raise, secure an approximately €355 million financing package and provide strategic and operational support throughout the development of the platform.

Construction of the first cluster of ten biomethane plants commenced in September 2024. The facilities include direct injection into the Italian natural gas grid, biogenic CO₂ capture units and organic fertiliser production facilities.

Building on the successful ongoing execution of this first phase, construction of a second cluster of ten plants commenced in May 2026, further strengthening Retina’s position as one of Europe’s leading biomethane platforms and reinforcing its contribution to Italy’s energy transition, the circular economy and the decarbonisation of the agricultural sector.

David Corchia, Co-founder of Eren Group (owner of Eren Industries), said:

“We are delighted to continue to invest in Retina, a major platform of our rapidly expanding global biogas activity. This partnership strengthens our commitment to transforming biomass, livestock manure and agricultural by-products into strategic energy resources while contributing to Italy’s energy transition. Together with Actarus Renewables and Retina SCA, we are developing a company that we believe will become a benchmark for the European biomethane industry.”
