Biodigesters
Harnessing the Power of Organic Matter
There are over two thousand biodigester sites in the United States.1 Dairy farms across the country are using biodigesters to reduce greenhouse gas emissions and create revenue opportunities.
A biodigester is a device in which organic waste matter is digested by bacteria to produce biogas and a nutrient-rich slurry. The nutrient-rich slurry is used as fertilizer and the biogas is either burned directly in an electric generator to produce renewable electricity or it is processed into renewable natural gas (“RNG”). RNG is a drop-in replacement for natural gas that can be blended with existing natural gas and moved through the existing natural gas transmission and distribution system.


Benefits of Anaerobic Digestion

Reducing potent greenhouse gases
Methane is 25 times more potent than carbon dioxide at trapping heat in the atmosphere.3 Managing methane from farm operations and manure provides climate benefits.

Removing odor and pathogens
The digestion process removes odors and pathogens from manure, improving the quality of life for those on the farm and those in surrounding communities.

Improving soil health
The liquid portion of the nutrient-rich slurry from the biodigester is used as fertilizer helping to improve soil quality and crop yields. The solid portion of the nutrient-rich slurry is used as bedding material for livestock on the farm.

Multiple end-use applications
Biogas RNG can be injected into the existing natural gas pipelines and used as a sustainable alternative anywhere conventional natural gas is used—electricity, heating, transportation fuel, and much more.

Adirondack Farms
Adirondack farms is a family-owned dairy farm in Peru, NY and has been operating a methane digester since 2017, creating energy that the community can use. Suburban Propane’s collaboration with Adirondack Farms will bring a new digester to the farm to produce renewable natural gas. Learn more about Adirondack Farms.
