2 CEPEA/USP 2007 Bazilian GDP was R$ 2,558,822 (~ 1.3 tillion US$)

4 Bazil Ethanol fom suga cane Pó Álcool (Pogama Nacional do Álcool ) 1975 esponse to oil cisis of the ealy 70 s Seveal cops wee tested (including cassava), howeve the low intenational pices of suga at that time and the infa stuctue in place led authoities to choose suga cane as the main cop fo this pogam 1978: Fist ca 100% ethanol

5 Bazilian plants Bazil has 357 plants (suga, ethanol and some electic enegy using bagasse Untill 2010 will be installed moe 88 mills: 19 in 2007/08; 36 in 2008/09; 33 in 2009/10 The total investment foseen fo the peiod (~13 billions US$) was ecently evisited to ~ 9 US$ billions

6 Bazil Ethanol Southen egion 6% (~29,8 Mton) of suga cane = 330 Kha wee not havest in 2008; SP 10 new mills that should stat poducing in 2008 ae not opeational; The secto faced low suga pice in the intenational maket; lowe demand on ethanol expotation and high level of shot tem investment; (Ag.

7 Biofuels Cetification The Babel of Cetifications National Standads Ethanol & Biodiesel Seveal cetification initiatives ae unde discussion now How to attend to all cetification discussions?

8 Baalcool Mill Baa do Buges, MT has 30,000 ha of sugacane, capacity of 14,000 t/day of sugacane. The fist in Bazil to poduce: suga, ethanol, enegy and biodiesel Bioediesel Plant

9 Electic and Mechanical Enegy geneation Thee is a need of 28Kwh to pocess 1 ton of suga cane; 2006 the co geneation in Bazil accounted fo MWh (~2% of the National electicity poduction); 55% fo industial pocessing in the industy 2025 the electical geneation can account to 38.4 GW (consideing pat used fo ethanol poduction) o 74.7 GW (if all bagasse is used fo enegy poduction)

10 Ethanol fom Suga Cane Co poducts/wastes geneated duing cane based ethanol poduction in Bazil: Filte cake: 12 kg/t suga cane Vinasse: lites pe lite of ethanol Bagasse: ~300 kg/t suga cane; bunt to supply enegy to suga mills and bioethanol plants Tash: 4Mha ae cuently buned befoe havesting; pogessive convesion to mechanical havest Luc M. Maene (IFA)

29 30% of the suga cane cultivated aea has mechanized havesting. Social poblem: unemployment but can we call suga cane cutting of a descent job?

36 Final Remaks The Bazilian expeience with bioenegy can bing inteesting lessons to the Wold; Bioenegy will pobably not have the impotance fossil fuels have today; A moe efficient use of enegy and, moe impotantly, changes in pattens of consumption ae the key solution fo the vaious enegy and envionmental poblems facing the Eath; ESSP Bioenegy Wokshop, Bazil, 2008

39 Wate use in the suga-ethanol industy Aveage of 35 mills in 1990: Demand 5.6 m33/ton of suga cane Use 1.8 m33/ton of suga cane Effluent 3.8 m33/ton of suga cane Aveage of 40 mills in 2004 Demand 1.8 m33/ton of suga cane Use 0.6 m33/ton of suga cane Effluent 3.8 m33/t of suga cane Souce: Elia Neto (2008) at State of São Paulo 2008: 163 mills Total tons of suga cane cashed: 325 million tons Demand: 325 million tons x 1.8 m33/ton of suga cane = 535 million m33 of wate Consideing a human consume of 0.15m33/day, 535 million m33, would supply a city of almost 15 million people (37% of the State of São Paulo population) Consideing a havesting peiod of 240 days would yield 26 m33/s, which equivalent to 20% of the industial wate use of the State of São Paulo
