Biogas (Biomethane, or Renewable Natural Gas)

Turning trash to cash, using our landfills to kick gas!

Biogas, also known as renewable natural gas (RNG), comes from gas produced during the natural breakdown of organic waste. Due to its renewable nature, biogas is extremely climate-friendly, releasing the lowest amount of greenhouse gas emissions of any commercially-available vehicle fuel. Sewage, agricultural waste and landfills are all potential sources of biogas, which can be used to heat buildings and fuel natural gas-ready vehicles. Landfills in particular can generate an astonishing amount of energy. For example, King County’s Cedar Hills Regional Landfill produces enough biogas to equal nearly 40,000 gallons of gasoline each day!
