Why is it important?

Ethanol is an alternative fuel produced from sugarcane and economically very important for São Paulo state and Brazil


The main contributions are the reduction in the water content (concentration) and increase in the solid and the potassium content (13.8%). The study showed a payback value of 5.49 years.
