This study evaluates economic feasibilities of the production and use of ethanol from cassava and sugarcane. Ethanol is a substitute for methyl tert-butyl ether (MTBE). A comparative evaluation between an ethanol-blend fuel—gasohol 95 (E10) and a MTBE-blend fuel (benzene 95) is based on life cycle assessment approach. The overall result indicates that the use of ethanol as a substitute for MTBE is economically feasible. This is as a main result of MTBE import substitution, reflecting the benefit to be generated if the domestic fuel crops were used to produce ethanol. Meanwhile the environmental benefit is found in a small proportion.
