Increasing of demand of corn for ethanol production places significant pressure on the availability of corn for food and animal feed. Other feedstocks such as crop residues, energy crops, wood waste, and forest residues are being considered for cellulosic ethanol production in the near future. The availability of crop residues for cellulosic ethanol production in Ohio was analyzed in this study. Results showed that two clusters of counties, with collection radius of less than 50 mile, have the capability to provide feedstock for two ethanol plants with feedstock demand of 5,000 dry ton per day each. These two plants would be located in the north western region of Ohio to produce 245 million gallon of ethanol per year. Other counties which have low biomass availability could grow energy crops such as switch grass and provide mixed feedstock such as forest residues, wood waste for a cellulosic ethanol plant.
