Environmental Life Cycle Implications of Using Bagasse-Derived Ethanol as a Gasoline Oxygenate in Mumbai (Bombay)

PDF Version Also Available for Download.

Description

Bagasse is the fibrous residue generated during sugar production and can be a desirable feedstock for fuel ethanol production. About 15%--25% of the bagasse is left after satisfying the mills' energy requirements, and this excess bagasse can be used in a bioconversion process to make ethanol. It is estimated that a 23 million L/yr ({approximately}6 million gal/yr) ethanol facility is feasible by combining excess bagasse from three larger sugar mills in Maharashtra state. The plant could supply about half of the ethanol demand in Mumbai, assuming that all gasoline is sold as an E10 fuel, a blend of 90% gasoline ... continued below

Description

Bagasse is the fibrous residue generated during sugar production and can be a desirable feedstock for fuel ethanol production. About 15%--25% of the bagasse is left after satisfying the mills' energy requirements, and this excess bagasse can be used in a bioconversion process to make ethanol. It is estimated that a 23 million L/yr ({approximately}6 million gal/yr) ethanol facility is feasible by combining excess bagasse from three larger sugar mills in Maharashtra state. The plant could supply about half of the ethanol demand in Mumbai, assuming that all gasoline is sold as an E10 fuel, a blend of 90% gasoline and 10% ethanol by volume. The life cycle assessment (LCA) performed in this study demonstrated the potentially significant benefits of diverting excess bagasse in Maharashtra to ethanol production, as opposed to disposing it by burning. In particular, lower net values for the ethanol production scenario were observed for the following: fossil energy consumption, and emissions of carbon monoxide , hydrocarbons (except methane), SOx, NOx, particulates, carbon dioxide, and methane. The lower greenhouse potential of the ethanol scenario is also important in the context of Clean Development Mechanism and Joint Implementation because India is a developing country.
