Abstract: Corn is one of the possibilities for diversification of Brazilian ethanol production. Four scenarios of analysis were established. The environmental dimension was evaluated by the Life Cycle Assessment (LCA) approach, whereas the Thermodynamic performance was verified by applying the techniques of Cumulative Energy Demand (CED) and Cumulative Exergy Demand (CExD). The production of ethanol from corn using wood chips for energy supply of the plant resulted in a homogeneous environmental performance. Factors such direct seeding ? and the LHV of the wood for energy support this result. For both Thermodynamic analysis the production of sugarcane ethanol had better indexes because the use of bagasse replaced other sources of primary energy. This...
