Aria Energy announces the commissioning of a landfill gas (LFG) to renewable natural gas (RNG) project at the Waste Connections-owned Butler County Landfill in David City, Neb.

Aria Energy constructed, owns and operates the project, which processes and purifies up to 1,000 cubic feet per minute of LFG into pipeline quality RNG.

LFG is produced naturally as waste decomposes and consists of roughly 50 percent methane. Landfills above a certain size are required to install a collection system to transport the gas to a collection facility to prevent it from rising into the atmosphere where it would become a greenhouse gas 21 times more potent than carbon dioxide. The captured LFG is purified into RNG which displaces the use of fossil fuels and can significantly reduce greenhouse gas emissions in the community.
