It is known that Brazil is the world largest sugarcane producer. But there is a great concern about the crop system of this culture, because the most common practice is the manual harvest with previous burning of the straw. But, this procedure is condemned by many organizations of society due to pollution. Then Brazilian authorities have approved a law prohibiting the burning of sugarcane crop residue prior to harvesting and established an agenda for the mills to stop this practice. On the other hand the mechanized harvest creates a new problem, to say, the dealing with the residue. Many studies have attempted to contribute to this theme. The most promising of all has proposed the use of the residue as part of the production system as a source of energy. The major difficulty for using the residue is how to transport economically the sugarcane harvest biomass from farm to processing center. For viability analysis is necessary to study the cost and energy balance in this system, because there are a large number of machinery involved in process. The aim of this work is to study the alcohol and sugar production chain and investigate mathematical models to estimate quantitatively the energy balance and production cost, considering all production process of alcohol and sugar, from the planting until cane to sale these products.
