Renewable Natural Gas Projects


We’re turning the definition of waste on its head. Our anaerobic digestion projects include vital partnerships with farmers, wastewater treatment plants, and other feedstock suppliers in order to transform farm cost centers to profits centers, while improving local air and water quality. Our biogas projects produce enough renewable natural gas to drive a car around the earth’s equator 2,400 times each year.


The Augean Project

The Augean project in Yakima County, Washington, converts 150,000 gallons per day of dairy waste from up to 7,000 cows into 160,000 MMBtu of renewable natural gas – the equivalent of 1.4 million gallons of gasoline – and other products each year. The project includes the construction of new pipeline infrastructure that sets the table for renewable natural gas projects at other dairies in the area.


The Demeter Project

The Demeter project near Madison, Wisconsin will convert 90,000 gallons per day of dairy waste from three local farms into biogas and other useful products, and it is projected to produce enough RNG each year to travel from San Francisco to New York and back over 200 times.


The Yellowjacket Project

The Yellowjacket project includes four anaerobic digestors at dairy farms in upstate New York that will convert a total of 225,000 gallons of dairy waste per day from 11,000 cows into biogas and other useful products.


The Sumter Project

The 1.546 megawatt Sumter project in Sumter, South Carolina uses methane biogas generated by customer Pilgrim Pride’s poultry processing facility to produce electricity and hot water. An on-site anaerobic digester recovers methane gas created in the plant and uses it for combined heat and power.

Let’s Connect

We’re always open to connecting with feedstock suppliers nationwide with an interest in developing anaerobic digestion/renewable natural gas projects.
