  1. Global Potential Bio-Ethanol Supply Presented to: CFR 521 Elliott Schmitt Photos from http://www.nrel.gov/biomass/photos.html

  2. Research Background/Sources • S. Kim, B. Dale. (2004). Global potential bioethanol production from wasted crops and crop residues. Biomass and Bioenergy 26 p.361 – 375 • Method for estimating Bioethanol potential • United Nations FAO-Statistics • ProdSTAT; global Agricultural product database • ForesSTAT; global forest product database • International Energy Agency – World Energy Outlook 2006 • Future Energy Scenarios & Trends • US DOE-EERE • Theoretical Ethanol Yield Calculator

  3. Biomass Types • Corn & Corn Stover • Barley & Barley Straw • Oat & Oat Straw • Rice & Rice Straw • Sorghum & Sorghum Straw • Wheat & Wheat Straw • Sugarcane & Bagasse • +Recovered Waste Paper • +Wood Residue (e.g. sawdust Studied Regions • Africa • Asia • Europe • North America • Central America • South America • Oceania

  4. Assumptions • Agricultural data from 2006 FAOSTAT • Theoretical Yields from US DOE • Waste Crops, crop residues, and waste material only From Kim & Dale • FBS (2003) • Bio-feedstock properties • Electricity & Steam generation from lignin ignored • 60% required ground cover for all crop residues, except rice • Ethanol is used in Medium-sized passenger E85 vehicle ~ 0.72 L of Gas per L of Ethanol

  5. Properties

  6. Total Feedstock

  7. Corn Crop • 64.2% of corn goes to Animal Feed • 4.6% of Corn is wasted • Corn Stover can produce 81.43 GL

  8. Barley 67% of Barley goes to animal feed.

  9. Rice 636 Tg of Rice produced globally in 2006 88% of Rice goes to food production. Rice Straw can potentially displace 43 Billion gal of Gasoline

  10. Recovered Paper • World bio-ethanol produced ~ 97GL • Theoretical Yield 116.2 gal/ton (Mixed Paper Waste) • All paper waste is converted, no recycling

  11. Wood Residue • World bio-ethanol produced ~ 282 GL • Theoretical Yield 100.8 gal/ton (Sawdust)

  12. Results!!! • World Crop production in 2006 was approximately 3674 Tg • An Increase of 174% from 2003 study • All crop production increased, except Oats which decreased by 4% • Sugar Cane production increased by 450% • Bio-crops in 2006 could potentially yield ~ 653 GL of Ethanol + 97 GL (Paper Waste) + 282 GL (Wood Residue) = 1032 GL of Ethanol • This is equivalent to 196 Billion Gallons of Gasoline (replaced in a mid-size passenger vehicle) • Asia has the greatest potential for Bio-ethanol production

  13. Future Energy Trends • Europe expected to overtake Brazil by 2010, and the US by 2030 • Global biofuels consumption expected to increase to73.0 Mtoe by 2015, and to 146.7 Mtoe by 2030 • US, Brazil, & Europe makeup 89% of consumption in 2015, and 69% in 2030 (China has major increase) • Global Oil demand expected to increase 116 mb/d in 2030 (140% increase) • Oil peaks in 2015, major oil supply from OPEC and Non-conventional Oil (shales)

  14. Conclusion • Rice straw has the greatest potential of all crops ~ 219 GL • All Crop residues in general are important for bio-ethanol production • Recovered Waste Paper & Wood Residues can play significant role • By 2030 with increased crop production for increased population (9 Billion), waste crops, residues, and products have good potential as bio-ethanol feedstock • Global Trade of biofuels should be encouraged in the future • Especially for Europe, who has minimal resources and a greater demand • Need to find ways to include developing countries (Africa) • More information needed to calculate land usage, and other environmental, economic, & Social Impacts
