Brazilian plants Brazil has 357 plants that produces sugar, ethanol and some of them also produce electric energy using bagasse Untill 2010 will be installed more 88 mills: 19 in 2007/08; 36 in 2008/09; 33 in 2009/10 Total investment = US$ 17 billions
Bioediesel Plant Barralcool Mill – Barra do Bugres, MT – has 30,000 ha of sugarcane, capacity of 14,000 t/day of sugarcane. The first in Brazil to produce: sugar, ethanol, energy and biodiesel

RESULTS - Between 1975 and 1979, ethanol production increased more than 500%. BRAZILIAN ETHANOL PROGRAM 1975 – high oil import costs + low world sugar prices Federal government promoted Ethanol production for blending-E20 Credit guarantees and low interest loans for new distilleries State trading enterprise began purchasing ethanol at high prices A marketing program Petrobras – ethanol distribution throughtout the country
1979 – Brazilian Government signed agreements with car companies for 100% ethanol powered cars 1985 – Troublesome period World oil prices dropped - reducing the benefit of replacing oil imports with ethanol. Brazil faced serious inflation problems and began a series of economic reforms. Differential price between ethanol and gasoline was eliminated. Differenciated loans for the construction of new distilleries were cut. BRAZILIAN ETHANOL PROGRAM RESULTS – Fiat, VW, MB,GM and Toyota produced 250,000 ethanol powered cars in ,000 in 1982
End of 1990´s – agreementes among Brazilian government and auto manufacturers for development of flex fuel vehicles – Government proposed a preferential tax for flex or ethanol fueled vehicles, a 14% sales tax, as compared to a 16% sales tax on non-ethanol fueled cars. BRAZILIAN ETHANOL PROGRAM 1990 – Low profile for Brazil´s ethanol program – Government required that all gasoline sold in Brazil contained E20% RESULT - Ford launched the first flex fuel prototype in 2002, with VW following in 2003.

Electric and Mechanical Energy generation Mills and distilleries also generated 11.3 TWh of electric and mechanical power, most of it for self consumption. That is equivalent to 3% of the electric power consumed in the country. The use of bagasse as a fuel is equivalent to 20.2 M tons of oil

GHG emissions avoided by the sector in 2003 were as follows: - for ethanol replacing gasoline: 27.5 million tons of CO 2 equivalent -for cane bagasse replacing fossil fuel in sugar production: 5.7 million tons of CO 2 equivalent. GHG EMISSIONS BY THE SECTOR For every additional 100 million tons of sugar-cane, 12.6 million tons of CO 2 equivalent worth of emissions could be avoided over the next few years using ethanol, the bagasse and the additional electric power surplus.
Conclusions Since 1975, when Brazilian Ethanol Program was launched, it remains the largest commercial application of biomass for energy production and use in the world Over the last 22 years, savings amounted to 1,8 billion US$/year with the replacement of ~ 200,000 barrels of gasoline/day Social Impacts - More than 720,000 direct jobs and 200,000 indirect jobs in rural areas – decreasing social and environmental disruption in big cities
Conclusions With high oil prices (> US$40/barrel) With low oil prices (< US$40/barrel) Economic incentive for Ethanol Program Ethanol Program depend upon its contri- bution to curb the greenhouse effect New sugar mill and distilleries plants will produce: sugar, ethanol, eletric energy, Biodiesel, sucrose byproducts and ethanol from sugarcane biomass. Future - new technologies : bagasse and trash gasification and hydrolisis, Industrial automation, fermentation process – yeast breeding, precision agriculture, genetically modified sugarcane. Brazil is interested in establishing a global market for ethanol as a traded commodity.
