7. Ethanol/Biodiesel Integration Barralcool (Mato Grosso State) Produces: 100,000 mt/year of Ethanol 50,000 mt/year of Biodiesel

8. Biodiesel Program  B2 mandatory at Jan/2008 (850,000 ton/year)  B5 mandatory at Jan/2010 (2013, originaly) Now:  10 biodiesel plants working (500,000 ton/year)  2,000 gas stations providing B2  Some transportation companies using B30  Projects: More than 100 new biodiesel plants LOW FEDERAL TAXES FOR SOCIAL PROJECTS AND POOR REGIONS

No acidity limits in the feedstocks

18. CONCLUSIONS  Brazil is open to share experiences in biofuels and offers good opportunity for international colaborations and investments in this field.  Both ethanol and biodiesel production will significantly increase in the next years. There’s agricultural land to support this increasing.  Integration between ethanol and biodiesel plants is strongly competitive.  Biodiesel process is being adapted to tropical feedstcoks (larger acidity) with higher yields and lower operating costs.
