GFL Environmental (NYSE and TSX: GFL) was at last look up 3.3% in US premarket trade on Monday as it and OPAL Fuels (Nasdaq: OPAL) announced that their joint venture, Paragon RNG, has commenced commercial operations of their new renewable natural gas facility at the Sampson County Landfill.

A statement noted the landfill, owned and operated by a subsidiary of GFL, is located in Roseboro, North Carolina. The plant is producing and injecting pipeline quality RNG. GFL said EPA registrations have been filed for the project and the company expects a "normal ramp-up period" for the facility.

Monday's statement noted the project is part of the prior announced joint venture between the two companies to develop RNG facilities at landfills owned by GFL. Having completed construction of the facility, OPAL Fuels will operate the facility and dispense the RNG as vehicle fuel for GFL's fleet and other transportation customers.

Monday's statement also noted the Sampson RNG facility has a nameplate design capacity of approximately 1.6 million MMbtu (12.4 million GGE) per year of RNG. This RNG, when used as transportation fuel to displace diesel, will reduce fleet operating costs and avoid GHG emissions equivalent to achieving zero Scope 1 and Scope 2 emissions from more than 900 heavy-duty trucks.

Patrick Dovigi, founder and CEO of GFL, said: "This facility at our Sampson landfill will play an important part in achieving our commitment to reduce our greenhouse gas emissions from landfills, while providing an alternative fuel source that can power our trucks and help our customers achieve their own sustainability goals."
