  1. Integration of Bio-Refineries with Anaerobic Digestion Facilities Bret Healy, River Bluffs Strategies bjhealy928@yahoo.com 605-216-1825

  2. US RFS Carve Outs • Only 15 bgy can come from cornstarch • 16 bgy must come from fuels derived from cellulose, hemicellulose or lignin • 1 bgy must come from biomass biodiesel • 4 bgy of other advanced biofuel may come from any fuel that qualifies as advanced biofuel – must reduce GHG 50%

  3. United States Renewable Fuel Standard 2012 Total 15.2 billion gallons/year

  4. United States Renewable Fuel Standard 2015 Total 20.5 billion gallons/year

  5. United States Renewable Fuel Standard 2019 Total 28 billion gallons/year

  6. United States Renewable Fuel Standard 2022 Total 36 billion gallons/year

  7. Sorghum Niche in RFS • Starch from Grain Sorghum may qualify as an advanced biofuel (if 50% reduction in greenhouse gas emissions) • Replacing natural gas in renewable fuel manufacturing will be necessary to achieve the 50% reduction needed • Animal waste may represent a novel approach to replacing natural gas in ethanol manufacturing • Other bio-wastes may also fit this role

  8. Needed Components • Ruminant livestock feeding • Source of manure for anaerobic digestion (AD) • Robust demand for wet distiller’s grains • Viable AD technology • Alternative Starch Crop production, current and potential • Grain sorghum • Barley • Feed wheat, oats, millet • Pathway to Advanced Biofuel status – current NODA published in Federal Register

  9. Geographic outline • Montana (eastern) • N Dakota (southwestern), S Dakota (central), Nebraska (western) • Kansas (central and western) • Colorado (eastern) • Panhandle of Texas, Oklahoma • New Mexico (northeastern)

  10. Existing ETOH Bio-refineries • State # MGY-nameplate • Montana 0 0 • North Dakota 6 358 • South Dakota 15 1,016 • Nebraska 26 1,544 • Kansas 13 492 • Colorado 4 125 • Texas 4 250
