Waga Energy to produce RNG at Rockingham County Landfill in North Carolina

Renewable natural gas (RNG) producer Waga Energy has been selected by Rockingham County to establish an RNG production facility at the Rockingham County Landfill in Madison, North Carolina, it said on May 14.

Waga Energy has entered into a 20-year agreement with Rockingham County to install its patented Wagabox technology at the landfill. The company will finance, build, own, and operate the unit, sharing the revenue from RNG sales with the county. The Wagabox unit is expected to be operational by 2026, producing approximately 207,000mmBtu/year of RNG. This RNG will be directly injected into the local natural gas pipeline.

According to Waga Energy, the project will avoid 13,500 tonnes/year of CO₂ equivalent emissions, based on calculations from the US Environmental Protection Agency (EPA). The Rockingham County Landfill serves over 92,000 residents and receives an average of 100,000 tonnes/year of municipal waste.

Waga Energy currently operates 23 Wagabox units worldwide, including three in North America, with 13 more under construction, six of which are in the US. In January, Waga Energy announced a deal with Decatur Hills Landfill to establish an RNG production facility at the Greensburg landfill in Indiana.

RNG, also known as biomethane, is a sustainable and environmentally friendly gas derived from organic materials. It is produced through the natural breakdown of organic matter in landfills, wastewater treatment facilities, agricultural activities, and other organic waste sources.
