WHAT IS RENEWABLE NATURAL GAS (RNG)

Renewable Natural Gas (RNG) is a clean source of energy made from organic waste materials. RNG is made from waste generated by agriculture, farms, landfills, biomass wastes from forests (i.e., dead trees), and wastewater treatment facilities.

The most common RNG production process captures naturally occurring methane from the decomposition of organic materials. Instead of allowing the methane to rise into the atmosphere as a greenhouse gas and further contribute to climate change, the methane is immediately captured, processed, and then injected into the gas pipeline as energy to power buildings, homes, and vehicles. 
 

How it works

Step 1: Waste from dairy, farms and landfills

Capture waste from dairies, farms and landfills

Step 2: Convert to Biogas

Convert into biogas using anaerobic digestion

Step 3: Make it pipeline ready

Process the biogas to make it pipeline-ready (biomethane)

Step 4: Inject into pipeline

Inject the biomethane into the pipeline for future use

What you need to know

California’s biggest sources of methane are waste streams from:

  • 56% Dairies, Livestock & Agriculture
  • 21% Landfills
  • 16% Oil and Gas Extraction
  • 7% Industrial and Misc.
