The next time you drive past a farm and smell cow manure, here's something to think about while you're holding your nose. The stinky stuff could someday be an inexpensive source for fueling your car and powering your home... The process of turning the waste into natural gas by using what are called anaerobic digesters, has become much more efficient. "We take the manure from the cows and put it into sealed digester vessels, the manure is heated to 100 degrees at which the bacteria produces methane and CO2, which is called biogas. The Biogas is cleaned to remove the CO2, using water and pressure to create biomethane, which is then odorized to create renewable natural gas" explains Mark Stoermann of AMP Americas, an energy company partnering with Fair Oaks Farm to create the fuel.
