Enviva Partners and GreenGasUSA, an integrated RNG solutions provider, have announced 10-year offtake agreement to decarbonise natural gas-related emissions in Enviva’s operations.

The agreement is expected to eliminate more than 64,000 tonnes of CO2 equivalent from the atmosphere every year – equivalent to 14,000 passenger cars removed from the road.

Enviva’s commitment underwrites a standalone GreenGasUSA project to install equipment that captures and treats methane currently being released directly into the atmosphere at a food processing facility in rural South Carolina.

As part of the agreement, GreenGasUSA will transport the RNG directly to Enviva’s Hamlet plant to be utilised in its control equipment in place of fossil natural gas in the third quarter of 2022.

The elimination of direct methane emissions at the food processing facility and conversion of these gases into RNG will be one of the first food waste-to-RNG projects conducted in the US Southeast.

The methane captured and emissions eliminated through this agreement will offset approximately 75% of all Enviva’s direct emissions from its manufacturing operations (Scope 1) annually, for the duration of the 10-year agreement.

“We’re proud to partner with GreenGasUSA to minimise the use of fossil fuels in our Scope 1 emissions and execute on highly effective carbon-neutral strategies,” said Thomas Meth, co-founder and executive vice-president of sales and marketing at Enviva.

“Selecting GreenGasUSA for this project was a natural choice as several of its agriculture partners are in close proximity to our existing operational infrastructure. The environmental benefits they provide to the communities they serve and their potential to grow and expand with us as a service provider underscores our excitement about this new collaboration.”

GreenGasUSA founder and CEO Marc Fetten commented: “GreenGasUSA is grateful to work with Enviva on projects like this. Methane capture from agricultural sources is one of the most impactful things we can do to combat climate change. We are thankful for the leadership of Commissioner Weathers and our farming community for embracing these efforts.”
