Environmental and economic analysis of the fully integrated biorefinery

摘要: Cellulosic biofuel systems have the potential to significantly reduce environmental impact of world's transportation energy requirements. However, realizing this will require level thinking and scale integration. Until now, we lacked modeling tools for studying behavior integrated cellulosic systems. In paper, describe a new research tool, Biorefinery Farm Integration Tool (BFIT) in which production fuel ethanol from biomass is with crop animal (agricultural) models. Uniting these three subsystems single combined model has allowed, first time, basic economic analysis production, possible secondary products, fertilizer bioenergy across various regions United States. Using BFIT, simulate embedded realistic agricultural landscapes nine locations under collection farm management scenarios. This approach permits profitability highlights key areas improvement. These results show advantages introducing biorefinery within landscapes. particularly true Midwest, our suggest good setting industry. Specifically, that inclusion into existing agriculture enhances economics reduces total landscape emissions. Model also indicate limited price effect increased distance. Sensitivity using BFIT revealed those variables having strongest effects on overall system performance, namely: size, switchgrass yield, gate price.
