Anaergia, Eni and CREvolution forge renewable fuels partnership

Anaergia Inc., through its subsidiary Anaergia S.r.l, has entered into a contract with Circular Renewable Evolution S.r.l. (CREvolution) to supply its proprietary anaerobic digestion technology at Eni S.p.A.’s biorefinery in Gela, Italy. The agreement includes approximately C$13 million (approximately $9.53 million U.S.) of Anaergia equipment and systems.

According to the companies, the initiative will sustainably produce hydrotreated vegetable oil (HVO), biodiesel, biojet (or sustainable aviation fuel), bionafta and bio liquefied petroleum gas. By developing a system designed for replication across global biorefineries, the partnership aims to establish a path for large‑scale rollout.

“Through this initiative, we are setting a new benchmark for sustainable HVO production,” Fabrizio Lami, chief operating officer of Italy-based CREvolution, says. “Efficient waste reduction, cost optimization, and circularity will be essential competitive differentiators as the HVO market accelerates.”

The project will integrate Anaergia’s advanced anaerobic digestion system with a complementary thermal treatment process to recover and regenerate degumming soil, currently treated externally and often bound for landfill. Anaergia’s proprietary high viscosity digestion technologies are engineered to process challenging, high dry matter materials. Anaergia says this will enable the facility to:

• recover more than 80 percent of degumming soil residues;
• generate more than 70,000 megawatt-hours of renewable natural gas annually;
• materially decarbonize energy use at the Gela refinery; and
• significantly reduce operating and waste disposal costs.

“This collaboration underscores Anaergia’s strength as a technology partner to some of the world’s most forward-looking energy companies,” Assaf Onn, CEO of Burlington, Ontario-based Anaergia, says. “By transforming what was once considered waste into renewable energy and reusable material, we are enabling a scalable solution for a rapidly growing HVO market.”

Installation and commissioning are expected to be completed by May 2027.

Once validated, the Gela facility model is expected to be replicated across Eni’s biorefineries and adapted broadly across the global HVO industry.

“This initiative demonstrates Eni’s commitment to sustainable innovation with measurable impact,” says a spokesperson for Italy-based Eni. “By regenerating degumming soil through an integrated process that also produces renewable energy, we significantly reduce waste-disposal costs and operating expenses while advancing circularity across our biorefining operations.”
