ObjectivesProject
Brazil`s Sugar and Alcohol Agribusiness Importance Introduction
Moves: $ 19 billion
Generate: 4 millon jobs
Involves: 72 mil farmers
Process: 420 millon tons of sugar cane
Produce: 30 millon tons of sugar and 17 billon liters of alcohol
Export: 19 millon tons of sugar and 3 billon liters of alcohol
Collect: $ 6 billon in taxes and fees
Invest: $ 3 billon per year
About 85% of Brazil`s sugar and ethanol production is concentrated at the Center-
South region.
Brasil is leader on sugar and ethanol export
