Sugarcane Sweet Sorghum Grasses Silage Corn Trees Urban Tree Waste Vegetable Waste Data Compiled and Calculated by Drs. Mary Duryea & George Hochmuth; UF/IFAS; May 2007
Sugarcane The DOE reports that the U.S. can produce over 1.3 billion tons of cellulosic biomass per year. • Our Potential in Florida: • Agricultural Crops: 11.49 mill tons/yr • Tree Crops: 64 mill. tons/yr • Ag/Forestry Waste: 18 mill. tons/yr • 93.5 million dry tons biomass x (60 to 100 gal ethanol/ton) = • Florida currently uses 8.6 billion gallons of gasoline per year Sweet Sorghum Cellulosic Biomass for Ethanol 93.5 million dry tons/yr in Florida (7% of U.S. total) Grasses Silage Corn Trees Potential Production of Ethanol 5 to 9 billion gallons of ethanol per year in Florida Urban Tree Waste Vegetable Waste

UF/IFAS & Cellulosic Ethanol • New Center of Excellence – Biofuel Pilot Plant $2.25 million – under construction in Gainesville • New Research and Demonstration Cellulosic Ethanol Plant $20 million from State Legislature • To be located at FL Crystals near Belle Glade • Goals = • To accelerate commercial development of cellulosic ethanol processes and • To provide alternative income sources for Florida agriculture and forestry.
UF/IFAS & Bioenergy: • Developing Energy Crops: • Increasing yield • Improving processing efficiency
1. Developing Energy Crops –Energycane, Grasses, and Sweet Sorghum • 45 sugarcane hybrids selected for biomass production are being evaluated at Everglades REC • The best performing hybrids will be evaluated for cellulosic conversion to ethanol • hybrids could produce over 2,000 gallons of ethanol per acre
1. Developing Energy Crops –Grasses -- High Biomass Crops • Other high biomass crops being investigated include: • Giant reed • Erianthus • Elephantgrass • Miscanthus
Research is being conducted to: Determine the best varieties for Florida Evaluate fertilizer and water requirements Results will help investors and growers make informed decisions on sweet sorghum as an energy crop 1. Developing Energy Crops –Sweet Sorghum

Target Traits for Bioenergy Production cell wall chemistry lignin hemicellulose cellulose 2. Developing Energy Crops –Improving Processing Efficiency • Fast Growth - high yield per unit input • Biological Conversion • High carbohydrate content • High ‘easy-to-utilize’ carbohydrates • Low lignin, low extractives • Thermal Conversion • High energy content • High wood density, low water • High lignin, high extractives
2. Developing Energy Crops –Improving Processing Efficiency • Discovered a new gene that will help ethanol production – • Naturally occurring gene in the tree species Populus • Leads to a reduction in lignin content by almost half • Results in faster growth and • Has higher cellulose content. • This combination is highly favorable for increased ethanol production.
