  1. Comparative Regional Economic Advantages for Cellulosic Feedstocks for Bioenergy Production. Burton C. English

  2. Use this time to address some questions • Bioenergy – Potential Feedstocks • Residues or Dedicated Energy Crops? • What is the UT Switchgrass Project?

  3. Renewable Energy Feedstocks From Agriculture

  4. Geographical Competitiveness • Biomass conversion to energy utilizes a number of different feedstocks including agricultural and forest residues, mill and urban wastes, and dedicated crops. Information on the quantity of feedstock supply available at the county level exists for prices ranging from $12.50 to $100 per dry ton (excluding transportation costs) for agricultural and residues, mill and urban wood wastes, and switchgrass.

  5. Geographical Competitiveness • Agricultural Residues – complementary products in the production of grain and oilseed crops and consists of corn stover and wheat straw derived from data supplied by Nelson (2002), • Forest Residues – consist of logging residues and other removals, • Mill Waste – by-product resulting from operations at primary mills that convert round wood products into other wood products generally consisting of bark, fine wood residues, and coarse wood residues, • Urban Wood Waste – wood contained in municipal solid waste streams including such items as containers, crates, pallets, furniture; yard trimmings; residential and non-residential construction wastes; residential and non-residential demolition wastes; and renovation and remodeling wastes, and • Dedicated energy crops

  24. What is switchgrass? • Native to the United States • Warm Season Grass • Managed using common agricultural practices • High yielding, drought tolerant, and requires lower fertilizer and herbicide quantities than traditional crops • Planting-May to early June and can use no-till practices • As a perennial, needs to be planted only once every 10 years or more • Harvested annually, either in a two harvest system or a one harvest system after the first frost, using conventional hay equipment

  25. What is the UT Switchgrass Project? • The switchgrass project has three questions to address. • What incentives are required to induce producers to convert commercial cropland to switchgrass? • What impact would a mature switchgrass feedstock industry have on Tennessee’s economy and the Nation’s agricultural sector? • What is the potential of converting switchgrass to bio-oil for use as light-off fuel in a coal fired burner or some other conversion process?

  26. What incentives are required to induce producers to convert commercial cropland to switchgrass? • Several Steps • Plant 32.5 acres on Experiment Station land • Develop recommendations from literature and from experience • Contract with producers to grow switchgrass • Analyze the experiences of the producers and those of the experiment station • Feed information learned into the Second Question • Use switchgrass grown to develop potential bio-energy market

  27. Experiment • Video • Two experiments • Variety yields • Seeding Rate X Fertilization Level X Landscape • Seeding Rate 2.5, 5, 7.5, and 12 pounds per acre • Fertilization Rates 0, 60, 120, and 180 pounds of N • 4 Different Landscapes

  30. What incentives are required to induce producers to convert commercial cropland to switchgrass? • We also conducted a survey of Tennessee producers. • Found that Currently (pre Bush January 2005 speech) 29% of producers willing to grow switchgrass, 25% would not. The other 45% would need additional information before deciding. • Of the 45%, An estimated probit model indicated that 75% would likely say yes.
