  1. BIOENERGY

  2. OUTLINE • Introduction • Why Bioenergy? • Cellulosic Ethanol Technology • Challenges • Industrial tour • Importance in my research • Summary

  3. Introduction • Southeast: • Favorable climate • Multiple feedstocks • Existing infrastructure The University of Georgia Conference Center

  4. Why Bioenergy? • Reduce the dependence on imported oil (US imports 10 million barrels per day). • Reduce the release of greenhouse gases (Bioethanol reduces accumulation of carbon dioxide by 90% compared to reformulated gasoline).

  5. Why Bioenergy? • Petroleum represents a 40% of the source energy used in USA. • Cellulosic biomass is an inexpensive resource. • When added to gasoline, increases octane and provides oxygen, increases combustion reducing the gas pollution.

  10. Cellulosic plants Challenges Identify the best conversion Technologies Development of public-private sector partnerships

  11. Ethanol • Today ethanol is made primarily from starch based sources like corn and sorghum. • Ethanol production has a 34% energy gain (1 gallon of ethanol contains more energy that is required to produce it). Gasoline has an energy loss of 19.5%.

  12. Ethanol and Corn Prices Source: USDA (United States Department of agriculture)

  13. Challenges • Develop fuels and chemicals by forestry and agricultural residues. • Cost reductions  technology advances (>100 gallons per ton of dry cellulosic biomass). • Important cost contributors (feedstock costs represent 70-80% of the final product cost).

  14. Challenges • Pretreatment (less chemicals and energy). • In 2025 farms will provide 25% of the total energy consumed in USA. • Georgia is projected to produce 100 million of biodiesel and 400 million of ethanol by 2012. • To produce 36 billion gallons of ethanol in 2022.

  15. Industrial Tour

  16. FIRST UNITED ETHANOL 100 Million gallon corn ethanol facility

  17. Products for: laminating, painting, moulding, shaping and wrapping Timber processing 100% Southern Yellow Pine

  18. Steam Boilers • Hot Water Boilers  • Wood and Waste Fired Boilers • BioMass Boilers Goal: reduce or eliminate energy and waste disponsal costs

  19. PLYWOOD OPERATION PAULOWNIA TREE Production: 40 tons per acre per year

  20. Importance in my research • Pretreatment represents about 20% of the total production cost. • Pretreatment disrupts the naturally resistant carbohydrate-lignin shield that limits the accessibility of enzymes to cellulose and hemicellulose. • The chemical pretreatment offers high yields and low costs  economic success.

  21. Summary • Pretreatment is the key to obtain low costs. • Achieve high yield of sugar from biomass with low cost. • More study is needed to make a commercial process. • It is important to integrate the process.

  22. Summary • The Souhteast can be a national leader in biofuel production due its high feedstocks resources. • Develop effective policies to accelerate commercialization, improve knowledge of cellulosic conversion and identify new technology.
