Anaergia renewable natural gas contract will see the company deploy anaerobic digestion systems at a large-scale agricultural facility in the United States.
Anaergia, through its subsidiary Anaergia Technologies, signed a C$58 million agreement with Neogenyx Fuels, a joint venture between Ameresco and HA Sustainable Infrastructure Capital (HASI).
The project will use anaerobic digestion technology to process agricultural waste and generate biogas, which will then be upgraded into pipeline-quality renewable natural gas (RNG).
Anaergia renewable natural gas contract expands agricultural waste-to-energy deployment
The Anaergia renewable natural gas contract includes turnkey manure handling, processing, and digestion systems capable of producing more than 4,400 standard cubic feet per minute of biogas.
Renewable natural gas is produced by capturing methane emissions from organic waste sources such as agricultural residues, food waste, and wastewater sludge, before refining the gas for use within existing natural gas infrastructure.
Agricultural waste projects are increasingly viewed as a significant growth area within the renewable fuels sector due to their potential to reduce methane emissions while generating low-carbon energy.
Industry investment in RNG infrastructure has accelerated in recent years, supported by energy transition policies, emissions reduction targets, and demand for lower-carbon fuel alternatives.
Renewable natural gas and energy transition strategies
The Anaergia renewable natural gas contract reflects wider growth in anaerobic digestion and waste-to-energy technologies across North America and Europe.
RNG is often promoted as a dispatchable renewable fuel that can integrate into existing gas networks and support sectors where electrification remains difficult.
Supporters argue that anaerobic digestion systems can help reduce emissions from agriculture while improving waste management and generating additional revenue streams for rural economies.
At the same time, debate continues around the long-term role of renewable gas within broader decarbonisation strategies, particularly regarding scalability and lifecycle emissions performance.
The agreement also highlights increasing collaboration between infrastructure investors, renewable energy developers, and technology providers as demand grows for lower-carbon fuel production systems.
