Closed Loop Ethanol Refinery Powered by Cattle Manure

Press Release 10.27.05:
"The system incorporates a dairy or feedlot, an ethanol production process, and an anaerobic digester into a self-sustaining, closed-loop system. The manure from the livestock is handled by an on-site waste management facility and turned into biogas. This biogas powers the ethanol production process, eliminating fossil fuel costs. Wet distillers grain � a co-product of the ethanol production process � is fed to the livestock, completing the loop.

The E3 BioFuels Complex has been designed around the existing Mead Cattle Company feedlot, which has a capacity for 30,000 head of cattle. The ethanol production component was tailored to fit the size of the feedlot and will produce approximately 24 million gallons of fuel-grade ethanol annually. The ethanol plant will process more than 8 million bushels of corn annually and produce 100,000 tons of wet distillers grain."
