Resumo:

Brazil has the world largest and most successful program to replace fossil fuels by ethanol from sugarcane which has made great progress over the last 30 years. The expansion of renewable sources from alternative raw materials and production processes are environmentally friendly requirement for the growing demand for ethanol as a fuel, to reduce emissions of greenhouse gases. The new world scenario leads to the advancement of technology for biofuels of which ethanol using agricultural biomass is a prime example. In this context, transforming the bagasse and cane straw (trash), processing by-products into raw sugar industry, is an alternative technology route that promises significant productivity gains in the fuel ethanol industry. Needless to say, the global environmental impacts of fossil fuels is one the major causes of pollution. Thus, the change in this matrix with the global adoption of biofuels is, in the sort term, the main way to reduce the environmental impact of fossil fuels.
