| Summary |
An investigation of a process to convert corn stover to biogasoline via gasification and Fischer-Tropsch synthesis was initially undertaken. Extensive process analysis and economic assessment established that this process is very inefficient, and is neither economically viable nor environmentally sound. Consequently, our group explored alternative uses for corn stover feed stock. Five different processes were evaluated, and one was chosen for further analysis: bio-digestion of cow manure to biogas. In this process, waste manure is collected from a feedlot and fed into a twophase bio-digestion system. The two-phase digestion system is based on a proprietary process: Onsite Power Systems anaerobic digestion. The process uses methanogen bacteria to convert organic solids into methane. The methane produced is then used to create electricity through a generator. The waste from the bio digesters can be sold as fertilizer. The feedlot will house 75,000 cows that produce 70,000 tons per year of harvestable manure. Preliminary calculations show that this manure will convert to 17.64 million cubic meters per year of biogas, which generates 38.8 million KWH per year of electricity, and will result in a gross profit of approximately $5 million
