  1. 1. Bioenergy systems and sustainable agricultural landscapes: a doable and reconciling agenda Weber A. Neves do Amaral, PhD University of Sao Paulo – Brazil Visiting Faculty – Fulbright Scholar - UNL Heartland Transatlantic Conference on Food and Fuels Lincoln, October 17, 2011 0
  2. 2. OutlineThe multiple roles and functions of agricultureBioenergy systems and sustainable agricultural landscapesFuture resarch challenges and opportunties for collaboration – UNL - USP
  4. 4. Humanity’s Top 10 Problems for Next 50 Years 1. Energy 2. WaterTop 5 associated 3. Foodwith Agriculture 4. Environment 5. Poverty 6. Terrorism and War 7. Disease 8. Education 9. Democracy 10. Population Richard E. Smalley, “Our Energy Challenge”
  5. 5. Ethanol custody chain – “Not in the kinder garden” 7 M ha Harvest > 420 mills & distilleries72 thousand growers 400 M tons (Operation & projects) ETHANOL SUGAR BAGASSE 27 billion liters 40 million tons Bioplastic Ethanol Derived Carbon Food credits Lysine Pharmacy 5
  6. 6. The role of sugarcane – energy suply – by source(EPE, 2009) Other Biomass Sugar Cane 12,4% 14.6% Hydroelectricity 14,8% Other Renewables 3.0% Uranium 1,6% Coal Petroleum and 6,0% Derivatives Natural Gas 37.9% 9,6% 6
  7. 7. Sugarcane bagasse complements the hydro-electricity generation in the winter Sugarcane and its contribution to the energy matrix/month - 2008 140 120 100 80 60 40 20 0 Jan Fev Mar Abr Mai Jun Jul Ago Set Out Nov Dez Energia Novas Hidrelétricas Biomassa Natural Fonte: UNICA – Etanol e bioeletricidade 7
  8. 8. ITAIPU = Sugarcane bagasse in 2015/16 2008: 94,5 TW/H/YEAR
  9. 9. Sugarcane plantations are mainly replacing pasture lands – 2/2 opportunity costs and carbon stocks – 85% of new areas Carbon uptake – t C ha/year(3 - 8) (22-36) 9
  10. 10. Land use process: reconciling multiple uses Food How to integrate Energy systems systems these systems at landscape level? Food Bioenergy Production Production Forestry Systems Systems Systems• Managing landscapes sustainably• Multiple products with value added and environmental services• Increase farmer´s income• Improve GHGs balances of current ethanol´s benchmark• Reduce the dependence on ethanol´s market price and supply options
  11. 11. Innovation for small sugarcane holders: biodiesel production and cattle confinement: positive impacts on carbon footprint and diversification at farmers levelSugarcane at landscape level Farmer´s cooperative multiple role Biodiesel plant and cattle confinement
  12. 12. BIOREFINERY – beyond sugarcaneAn approach for the forestry, pulp and paper industry AFS wood debarking chiping chips pulping energetics Soy bean jatropha extraction bark hemicelluloses black liquor sunflower carbohydrates cotton Oil seed crops fermentation destilation biodiesel energy Ethanol, buthanol methanol & pulp many other products paper 12
  13. 13. New technologies and innovation – UNL and University of Sao Paulo• Improving the productivity at agricultural and industry levels• Optimizing the use of feedstock: second generation - ligno-cellulosic materials• Reducing water use and waste generation• Adding value to ethanol co-products• Moving towards the full deployment of ethanol chemistry and biorefinaries
  14. 14. Brazil is establishing a Cellulosic Ethanol cluster with a significant number ofplayers... NON-EXHAUSTIVE Fund suppliers • Research Institutes 2nd Generation Suppliers Biofuels • Universities Feedstock/ Conversion UFPE 14
  15. 15. Biorefinary platforms Using biological systems to integrate multiple operations Destilation Cracking Cathalysis Hydrotreatment
  16. 16. To better understand some of these opportunities – we can´t afford notto have… the 5 CsConcentration and concerted efforts: focus and scaleContinuity: 30 years of investments worthwhile – the Brazil caseComplementarity: bioenergy sources and expertise – need for an interdisciplinaryapproachCommitment: to make a changeCoordination 16
  17. 17. Bioenergy and biofuels are not the panacea to solve all energyproblems, but can effectively contribute towards a low carboneconomy scenario in the present and in the near future.
