Abstract:

Commercial large scale microbial lignocellulosic biofuel production is in the process of being established but questions regarding biomass pretreatment, process design, biofuel yield, waste management and overall cost remain. Microbial bioethanol production, one of the most promising 2nd generation biofuels, must resolve issues on pretreatment, inhibitor production and pentose processing which may result in a complicated technology. Also are process plant size and surrounding infrastructure likely to have a high economical impact on the procurement of biomass, process steam and waste. To investigate if small scale lignocellulosic biofuel production close to municipal combined heat and power (CHP) production is favorable, we have recently published data on combined ethanol fermentation and biogas digestion of Oat straw [1]. Based on this we here discuss how process design, robustness, and co­product refinement and waste handling may enable lignocellulosic biofuel production to be integrated with existing CHP infrastructure at low capital investments.
