The turkey plant in Carthage produces 500 barrels a day from 200 tons of turkey waste. So that is 2 1/2 barrels per ton. The estimated cost is $15 a barrel, but that isn't the end all be all of the financial side. They also produce tons of high nitrate fertilizer, tons of methane (used by the plant for heating, so cost to purchase fuel for heating would be partially offset) and they reduce the landfill destined waste by a large percent (80% or more) saving transport and storage fees for the turkey plant.
