Waste water treatment facilities often are ideal venues for RNG development, as the waste collection infrastructure is already partially in place.
Agriculture waste feedstocks emit high levels of methane. Fortunately, RNG projects capture the methane that would otherwise emit into the atmosphere and contribute to climate change.
Waste already in place at landfills makes up about 10% of North America’s yearly methane emissions. We use biogas from waste at about 620 U.S. landfills today, but we could be producing RNG at nearly 500 more of them, according to U.S. EPA.
Americans discard 250 million tons of municipal food waste per yer. Food waste can be added to anaerobic digesters that create RNG from a variety of waste feedstocks.
