Tips to Install a Methane Digester - Green Homes - MOTHER EARTH NEWS

A methane digester — also known as an anaerobic digester — can be a great source of biofuel and fertilizer. From MOTHER EARTH NEWS magazine.

#3. "Methane Digester". Marshall, CA. The single largest source of pollution in the State of California is methane from cows. At Albert Straus’s family dairy a methane digester traps methane before it can enter the atmosphere, breaking it down into solids and liquid fuel that can be used to provide enough electrical power to run the entire dairy operation.
