What is Renewable Natural Gas (RNG)?

Renewable Natural Gas (RNG), also known as biomethane, is a clean and sustainable energy source produced by capturing and refining biogas from organic waste. This waste can come from sources like landfills, agricultural operations, wastewater treatment plants, and food processing facilities.

When organic materials break down in the absence of oxygen, they produce biogas – a mixture primarily made up of methane and carbon dioxide.

GreenGas is creating RNG by upgrading this raw biogas to remove impurities and concentrate the methane, resulting in a fuel that’s chemically identical to conventional natural gas and compatible with existing gas pipelines and infrastructure.

Why RNG is Good for the Environment

  • RNG provides a powerful environmental benefit by capturing methane—a greenhouse gas over 25 times more potent than carbon dioxide—and converting it into a usable energy source.
  • RNG is easy to purchase and use, as it seamlessly integrates with existing natural gas infrastructure and is increasingly available through utilities, energy marketers, and voluntary renewable gas programs—making the switch to cleaner energy simple for both businesses and consumers.
  • By integrating RNG into energy systems, RNG is helping decarbonize sectors like transportation, manufacturing, and automotive – offering a practical path toward a cleaner, more sustainable energy future.
  • Instead of allowing methane from waste to escape into the atmosphere, RNG systems trap and repurpose it, significantly reducing overall emissions.
  • RNG production supports a circular economy by turning organic waste into fuel, reducing reliance on fossil fuels, lowering landfill usage, and improving air and water quality.

Benefits of Using RNG In Your Portfolio of
Energy Sources

Carbon-Negative

When sourced from waste, RNG reduces more emissions than it produces and can decarbonize sectors that require reliable, high-temperature energy such as food processing, chemicals, manufacturing, etc.

Reliable Energy Source

The natural gas pipeline network enables a reliable supply of RNG compared to other intermittent sources of renewable energy.

Easy to Purchase

RNG is easy to purchase and integrate, as it’s compatible with existing natural gas infrastructure and available through many utility and energy providers.

Enables Resource Circularity

RNG supports a circular economy and sustainable resource cycles by transforming organic waste into clean energy, reducing emissions while creating value from discarded materials.
