Abstract: The processing of organic, cellulose-containing materials has been around for many years. Currently, due to high oil prices as well as the significant increase in ethanol usage nationwide from both grain based and cellulosic based sources, there is tremendous interest in developing efficient, cost-effective manufacturing processes to produce energy from cellulosic feed stocks. This article will use actual process data to highlight the choice of pressure or vacuum filtration and cake-washing techniques for these newly developed bioprocesses.
