What is renewable natural gas?

Staff Reports

What do farm animals and trash have in common?

They are both sustainable sources of renewable natural gas or RNG and key to Williams partnerships with dairies and landfills in several states.

Methane is a byproduct of waste decomposition. Capturing methane from dairies and landfills prevents the methane from being released into the atmosphere.

Instead, it’s turned into carbon-neutral pipeline quality natural gas.

At the George DeRuyter and Sons Dairy in Washington, methane from cow manure is cleaned and converted into renewable natural gas and injected into our Northwest Pipeline.

We are also partnered with landfills in Washington, Idaho, Ohio and Texas to transport natural gas made from extracted methane.

Renewable natural gas is often used for transportation fuels so the process is sometimes called “waste to wheels.”
