Topic:
A Life Cycle and Impact Assessment of Ethanol Production From
Various Biomass Sources


Abstract
Ethanol from lignocellulosic material is being considered an  
alternative or supplementary production system to the currently  
starch based ethanol industry in the United States.  This study  
focuses on the environmental impacts of large-scale long-term ethanol  
production from both starch and lignocellulosic-based biomass sources  
in the US.  Monte Carlo methods are used to apply probability  
distributions, which represent system inputs and outputs to account  
for the variability in agricultural and ethanol processing data.   
This model is also used to address questions regarding petroleum and  
natural gas consumption during the life cycle of ethanol production,  
system greenhouse gas emissions, geographic variation with system  
expansion, and land quantity for both starch and lignocellulosic  
biomass sources.
