Renewable Natural Gas
What is Renewable Natural Gas (RNG)?
According to the U.S. EPA, Methane—the primary component in natural gas—is the second most prevalent greenhouse gas emitted in the United States from human activities. In 2013, methane accounted for about 10% of all U.S. greenhouse gas emissions from human activities. Methane’s lifetime in the atmosphere is much shorter than carbon dioxide, but methane is more efficient at trapping radiation than carbon dioxide. Pound for pound, the comparative impact of methane on climate change is more than 25 times greater than carbon dioxide over a 100-year period.
Capturing, purifying and monetizing methane emitted via human activities, such as the raising of livestock and landfills, represents not only a better solution for the environment, but also an outstanding business opportunity. ARI’s AdvanSorb®-RNG gas processing technologies can successfully address methane losses from a variety of sources, including biogas from landfills, waste water treatment, agricultural waste, anaerobic digestion.
Together, these sources represent approximately 25%+ of the methane that is released into the atmosphere, in the U.S., due to human activity.
How Does RNG help Farmers?
To farmers, RNG is simple – it’s about responsible energy ingenuity. RNG is already being used by farmers around the world because it provides them with an effective waste management solution, while creating long-term financial and clean-energy assets.
While RNG can be created from a variety of different sources, farmers are in a unique position because the burdensome waste they regularly have to manage – whether it be food waste, crop residue, animal manure or wastewater – can now be used to create RNG.
By creating their own RNG, farms can create new revenue streams, not only from efficiently handling naturally occurring waste, but also from the sale of RNG to others. RNG production, through anaerobic digestion or “fermentation” of materials, yields valuable by-products for farmers, including more effective fertilizers and even recycled animal bedding, all of which can be used on the farm or sold for additional profit. While RNG is not exclusively useful to farmers, it is uniquely equipped to benefit their economic futures, our nation’s domestic food sources and farming communities.
RNG is helping American farming families continue their legacy of putting food on our nation’s tables and sustaining our economy at a time when farming in the United States has never been tougher.
