  • 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 exportSource: PROCANA SF 2006/2007
