Biochemical production of ethanol and fatty acid ethyl esters from switchgrass: analysis of environmental and economic performance

Source:  Dan Hawkes

SwitchgrassIn a recent study, ESD’s Harry Beller and others analyzed processes that could produce either ethanol or a representative fatty acid ethyl ester (FAEE) via the fermentation of sugars liberated from lignocellulosic materials pretreated in acid or alkaline environments are analyzed in terms of economic and environmental metrics. Recently, interest in the biochemical production of such so-called “drop-in” fuels has increased as a way to avoid the well-known shortcomings of ethanol as a fuel molecule and to potentially exploit the processing advantages of a water-immiscible fuel to reduce product recovery costs and energy requirements.
