Now Farm Livestock Can Help You “Fill ’or Up” Maybe you can’t make a silk purse out of a sow’s ear. But how about generating energy from cow manure? “The process actually is quite simple and will be demonstrated at 1973 Agricultural Progress Days” says Dr. Donald Harter, Chairman of the Environmental Improvement Exhibits Com mittee, and Penn State Area Resource Development Agent. The event will be held August 28- 29-30 at Milton Hershey School Farms, Hershey, Pennsylvania. Those attending will see a novel, anaerobic, methane gas generator designed and built by two members of the En vironmental Improvement Committee Lebanon County Agent Glenn E. Miller and Assistant County Agent Newton J. Bair - who are on the staff of Pennsylvania State University’s Cooperative Extension Service. Methane gas, the principal component of natural gas, is a product of microbial digestion (decomposition) under anaerobic conditions. The gas producing reactions proceed best at a temperature range of 85 degrees to 105 degrees. Methane is colorless, odorless, it burns cleanly, and is relatively pollution free. It already is used to power fleets of cars in a number of cities, including Philadelphia. The potential for producing methane from agricultural wastes is enormous.

In Pennsylvania 700,000 milk cows alone produce an estimated 1.75 million tons of dry organic wastes yearly. Dr. Harter points out, “The methane digestor was built for 1973 Ag Progress Days for three reasons: to demonstrate the energy producing potential of agricultural wastes; to en courage “futuristic” interest in using anaerobic digesters as part of a farm’s system for holding and disposing of manure; and as Just plain makes more sense!

Professor Ram Bux Singh, Director of the Gobar Station, provided a how-to-do-it manual and a literature search provided additional information to get started.
