RNG Basics

Turning waste into valuable resource

From garbage problem to energy solution

Renewable Natural Gas is a carbon-neutral energy that is created from decomposing organic waste. Methane emssions from municipal landfills, wastewater treatment plants, farms and industries can be captured, refined and converted into renewable energy, making constructive use of harmful waste gas. RNG is fully interchageable with conventional natural gas for transmission, distribution and everyday use.

RNG is:

  • Biogas that is captured and upgraded to generate energy
  • Constructive use of methane emissions, 25x more harmful than CO2
  • Fully interchangeable with conventional natural gas
  • Clean and sustainable energy source for Ontario

What is biogas?

  • Naturally occurring by-product of landfills, wastewater treatment, farms
  • Approximately 50% methane, 50% CO2
  • Currently burned off to prevent release of methane (25x more potent than CO2)
  • Can be captured and converted into a cleaner, renewable form of natural gas

Cleaner, greener natural gas
