"In fiscal year 2008, Tyson Foods began testing a renewable energy process at its feed mill in Fairmount, Georgia. This process, known as a biomass gasification technology, is designed specifically for poultry litter and other hard-to-process materials. The testing period lasted eight months and converted nearly 1,000 tons of poultry litter to 110-psig (pounds-per-square-inch gauge) steam. It supplied an estimated 30 percent of the feed mill's steam needs. The test is considered an operational success, achieving sustained gasification over extended periods and excellent results on stack emissions from the process. Tyson Foods continues to evaluate opportunities to install a scaled up version of this process at other company locations." Propane added when they burn dead chickens.
