AMERICAN SOCIETY OF AGRICULTURAL ENGINEERS. PAPER NO. 031165. Interpretive Summary: The use of biomass materials as a fuel source has recently been an item of renewed interest. The objective of this research was to determine the construction and operating cost associated with a facility designed to produce fuel pellets from cotton byproducts generated from a cotton gin. The gin used in the study processes an average of 55,000 bales a year. The pellet manufacturing plant would be located adjacent to the gin and process the byproducts as they are being generated. The COBY process developed at the USDA-ARS Cotton Production and Processing Research Unit in Lubbock, TX, would be utilized to manufacture the fuel pellets. Traditionally, the COBY process has incorporated extruders into the operation. However, this analysis was preformed by replacing the extruders with a pellet mill to allow for greater throughput (i.e. increased hourly capacity). The economic analysis incorporated cost of constructing the facility, as well as variable costs of transportation, labor, manufacturing, power, raw material supply, and maintenance. The evaluation used was performed by modeling the variable costs and assessing their effect on a specified return on investment (ROI) of 15%. Results from the forecast model indicate the probability of obtaining a 15% ROI to be 34.4% and 59.1%, depending on whether the product was shipped to market by either truck or by rail, respectively. All analyses performed included the costs of shipping the product to market from a production plant located near Lubbock, TX. The market locations evaluated in this study were Albuquerque, NM, Denver, CO, and Kansas City, MO.
