Significant amount of agricultural and forest operations are carried out in the Southeastern part of the United States. Waste materials are therefore generated during these operations. The purpose of this study is to characterize these waste materials in terms of their suitability as biofuel feedstocks (poultry litter, peanut hull, switchgrass, red oak shavings, red oak bark, and pine shavings). The properties that were measured include energy content, ash content, and density (bulk and particle). Result showed that poultry litter had the least energy content (~ 5600 BTU/lb) while peanut skin had the highest energy content (~9410 BTU/lb). A linear relationship was found between heating value and ash content of the biomass feedstocks. Density and compressibility of poultry litter were also significantly higher than those of the other biomass feedstocks.
