How does the methane digester work?

The methane digester on the Straus Organic Dairy Farm captures methane in the digested manure from approximately 300 cows. Almost 4,000 gallons of cow manure is collected from the barns daily. The digester then converts the manure to renewable energy and nutrient-rich compost.

Approximately 9.2 million standard cubic feet of biogas is captured from the digester annually, reducing harmful greenhouse gas emissions by 1,645 metric tons of CO2e.

The biogas is converted into renewable electricity, powering the entire 500-acre Straus Organic Dairy Farm. The amount produced annually is equivalent to removing 347 passenger vehicles from the roadways.*
