Fig. 7: Considerações: 50% Diesel substituído por etanol; 100% frota
Potencial de economia/safra: R$ 530 milhões
Considering the substitution ratio of 60% the costs of fuel will be 25% lower, reducing
ethanol price by almost 2%.
1.3 Ambient motivation for diesel substitution
In Brazil, the production of ethanol is one of the most efficient in the aspect of using
fossil fuels, but there still room for improvements.
Considering the carbon cycle, the use of fossil fuels will release Green House Gases
into the atmosphere.
Renewable fuels, made from biomass, uses CO2, water and solar energy to grow
plants, such as sugar cane, these operations, however still uses fossil fuels in the
form of fertilizers, process chemicals, lubricating oils and diesel fuel. See figure 8
below.
