Product Description
The Life Cycle Analysis of an Ethanol Plant utilizing Biomass develops an Inventory of emissions results, and calculates Life Cycle costs. This is a life cycle environmental and cost analysis of ethanol using starch and cellulosic feedstocks. It provides a life cycle comparison of three tiers of technology, three types of biomass feedstocks, and two fuel-blending compositions for a total of 18 distinct pathways. When ethanol is blended with gasoline at an 85/15 ratio between ethanol and gasoline, the life cycle greenhouse gas (GHG) emissions are highly variable due to different feedstock types and ethanol production technologies. The biochemical conversion of cellulosic feedstocks to ethanol has the lowest GHG emissions in this analysis, because of the energy recovered at the ethanol plant.
