Biogas/RNG
Renewable Natural Gas (RNG) is biogas produced and recovered at organic waste facilities (for example, landfills and wastewater treatment plants). RNG can be used to heat your home or business and for cooking just like conventional natural gas.
LIVESTOCK MANURE AND LANDFILLS ACCOUNT FOR 27% OF METHANE EMISSIONS IN THE U.S.
THIS IS THE SOURCE OF RNG.
When organic matter decays, it naturally produces methane: one of the greenhouse gases most detrimental to the environment. By capturing the methane, we prevent it from entering and damaging the atmosphere. Then, we turn it into renewable natural gas — the cleanest fuel in the world.
In the United States, regulations under the Clean Air Act require municipal solid waste landfills of a certain size to install and operate a landfill gas collection and control system. Some landfills reduce landfill gas emissions by capturing and burning—or flaring—the landfill gas. Burning the methane in landfill gas produces CO2, but CO2 is not as strong a greenhouse gas as methane. Many landfills remove moisture, siloxane, and sulfur from the biogas to generate electricity and some treat the biogas further to produce RNG.
