Biofuels production 2132005, ethanol production in Brazil was found to increase about 3-4% annually.
Presently, the use of ethanol as fuel by Brazillian cars - as pure ethanol and in
gasohol – replaces gasoline at the rate of about 27,000 m^3 per day or about 40%
of the fuel needed for the vehicles running on gasoline alone. Ethanol uses have
resulted in improved air quality in big cities due to better combustion efficiency
and also in improved water quality because ethanol (which is easier to be
biodegraded) replaces some toxic compounds of the gasoline. However, there
are reports of negative environmental impacts results from extensive ethanol
production from sugarcane. These include: reduced areas of food-growing
fields, social-economic effect on the poor farmers who have to give up food-
crop lands for biofuel production.
