Slide 1: Sustainable Energy Center Novel Processes and Feedstocks for Producing Biofuels Rafael Hernandez, Todd French, Mark Bricka, Andro Mondala, Jacklyn Hall, and Mark White Mississippi State University Statistics on Soy Biodiesel Production and Feedstock Availability: Source: http://www.soystats.com/2007/Default-frames.htm US Soybean Oil Production in billion pounds (1981-2006) US Biodiesel Consumption (1999-2006) Statistics on Soy Biodiesel Production and Feedstock Availability Soybean oil production 2.75x109 gal in 2006; no significant increase predicted in 2008. Consumption by the food industry reached 2.32x109 gal in 2006. Projection of 1.5x109 gal of biodiesel production in 2008 would require 1.65x109 gal of soybean oil. There is a need to search for other low-cost and abundant feedstock. Potential to produce oil from existing WWTF: 7x109 gallons Slide 3: Sustainable Energy Center Wastewater Treatment Facilities: A New Source of Crude WTFs could be modified to generate large quantities of lipids for the Production of Fuels and Chemicals. There is at least a WTF in every State of the Nation Slide 4: Sustainable Energy Center State of the Science: State of the Science Primary and secondary sludge from the Tuscaloosa Wastewater Treatment Facility has been extracted and converted into fatty acid methyl esters (FAMEs) Yields of 1 gallon FAMEs/100 lbs of sludge ($3.08/gallon) and 2 gallons of FAMEs/100 lbs of sludge ($2.08/gallon) were obtained for secondary and primary sludge, respectively. An estimated 1 billion gallons of oil could be obtained from conventional WWTF. Oleaginous microorganisms can accumulate more than 50% of their dry weight in oil. Secondary sludge oil yield may be increase by a factor of 8 (8 gallons of FAMEs/100 lbs sludge) using these microbes Wastewater treatment facilities has the potential of generating 7 billions gallons of oil per year Slide 6: Sustainable Energy Center Envisioned Process: The New Biorefineries Lignocellulose Environmentally Sustainable Fuel Production: Sustainable Energy Center Environmentally Sustainable Fuel Production Slide 8: Sustainable Energy Center By-product of the pulp and paper industry Producers Arizona Chemical, Georgia-Pacific, Eastman Chemical, and MeadWestvaco Products Specialty chemicals, inks, paper sizing agents, rubber, etc. Approximately 50 Mgallons of tall oil could be available for biodiesel production Tall Oil Industry Tall Oil Biodiesel - ASTM D-6751 : Sustainable Energy Center Tall Oil Biodiesel - ASTM D-6751 Slide 10: Sustainable Energy Center Chinese Tallow (Popcorn Tree) Sapium sebiferum Slide 11: Sustainable Energy Center Potential Oil Seed Yields Ref: Klass, Donald, Biomass for Renewable Energy, Fuels, and Chemicals, Academic Press, 1998. - - - CT Biodiesel Production Potential: Sustainable Energy Center CT Biodiesel Production Potential 20 Million Gallons 120,000 Acres of cultivation Only 10% of Mississippi’s Soybean Acres for 2002!
