to meet
the demand for
fuel in brazil​

Answer 1

Answer:

BRAZIL is the world's second largest producer of ethanol fuel. Brazil and the United States have led the industrial production of ethanol fuel for several years, together accounting for 85 percent of the world's production in 2017. Brazil produced 26.72 billion liters (7.06 billion U.S. liquid gallons), representing 26.1 percent of the world's total ethanol used as fuel in 2017. Between 2006–2008, Brazil was considered to have the world's first "sustainable" biofuels economy and the biofuel industry leader,a policy model for other countries; and its sugarcane ethanol "the most successful alternative fuel to date.Brazil's 40-year-old ethanol fuel program is based on the most efficient agricultural technology for sugarcane cultivation in the world,uses modern equipment and cheap sugar cane as feedstock, the residual cane-waste is used to produce heat and power, which results in a very competitive price and also in a high energy balance (output energy/input energy) Brazil has ethanol fuel available throughout the country. There are no longer any light vehicles in Brazil running on pure gasoline. Since 1976 the government made it mandatory to blend anhydrous ethanol with gasoline, fluctuating between 10% to 22%. and requiring just a minor adjustment on regular gasoline engines. In 1993 the mandatory blend was fixed by law at 22% anhydrous ethanol (E22) by volume in the entire country, but with leeway to the Executive to set different percentages of ethanol within pre-established boundaries. In 2003 these limits were set at a minimum of 20% and a maximum of 25%.[15] Since July 1, 2007 the mandatory blend is 25% of anhydrous ethanol and 75% gasoline or E25 blend.The lower limit was reduced to 18% in April 2011 due to recurring ethanol supply shortages and high prices that take place between harvest seasons.

EXPLANATION:

DURING FERMENTATION,YEAST PRODUCES CARBON-DIOXIDE AND ETHENOL. ETHHENOL IS USED IN BRAZIL TO MEET THE DEMAND FOR FUEL AND MANY OTHER SOURCES.
