  • Corn is approximately 70% starch. Remainder of kernel is protein, fiber, oil, minerals and vitamins fiber, gluten, germ). Other constituents are actually of higher value than the starch. DDGS = dried distillers grain with solubles, contains the other parts of the corn in a concentrated form – excellent high value feed.

    1. 1. POET BIOREFININGLADDONIA, MOSteve Murphy
    2. 2. LADDONIA PLANT FACTS • Began operation Sept. 26, 2006 • We operate 24/7 and year round • Majority Missouri farmer-owned through co-ops • Technology and management support from POET Plant Management – linked to other plants in the systemPAGE 3CONFIDENTIAL
    3. 3. 2011 PLANT PRODUCTION • 60 MGPY of ethanol / 170,000 per day – Ethanol is sold as E98 – Most ethanol stays in MO • 20+ M Bushels of Corn / 60,000 per day • Produce 160,000 tons of DDGS/year – 460 tons/day of dry product – Wetcake – Corn oil – started in December 2011 – Dry mill process – Other plants make other products (CO2, Inviz)PAGE 4CONFIDENTIAL
    4. 4. Corn Draw Area
    5. 5. Corn Draw Area
    6. 6. Corn Draw Area
    7. 7. POET WATER USE REDUCTION
    8. 8. POET BIOREFINING – LADDONIA WATER USE PAGE 10 CONFIDENTIAL
    9. 9. WATER USE PARAMETERS • Plant is supplied by two wells, potable water is from the city • Main water users are fermentation, cooling towers, and boilers • Incoming water quality determines treatment requirements and discharge rates • Effluent is regulated by state permits • Total Water Recovery (TWR = ZLD) - May 2011PAGE 11CONFIDENTIAL
    10. 10. WATER USE PARAMETERS • Water that has contacted corn or ethanol is considered “process water” and is 100% recycled • Discharge water is primarily Reverse Osmosis (RO) reject water • TWR installed in May 2011 recycles most of this RO reject waterPAGE 12CONFIDENTIAL
    11. 11. POET Biorefining – Laddonia Water Use
    12. 12. WATER CONSIDERATIONS • Quantity of water needed – Potential to handle expansion/growth – Cellulosic? • Quality of incoming water • Water discharge permit – cycle up incoming water how many times? • Food Safety Modernization Act (FSMA) - is water source compatible for animal feed products?PAGE 14CONFIDENTIAL
    13. 13. CO-PRODUCTS • Ethanol production uses only the starch from corn • DDGS (wet and dry) contain the other parts of the kernel – protein, fiber, oil, minerals and vitamins – 460 tons per day • Animal feed treated as part of the food chain and many food guidelines now apply as result of Food Safety Modernization Act (FSMA)PAGE 15CONFIDENTIAL
    14. 14. CO-PRODUCTS - NEW • Starting in December 2011, the Laddonia site also started separating corn oil from the syrup • This oil is used for biodiesel or as an animal feed energy supplement • Co-products are a key factor in energy intensity, carbon intensity, “food vs. fuel”, and plant profitabilityPAGE 16CONFIDENTIAL
    15. 15. ENVIRONMENTAL INNOVATIONS • 14MWH Heat Recovery Steam Generator (HRSG) turbine supplies steam to distillation and electricity to the grid • In-line blending of denaturant • All process water has always been recycled • Total Water Recovery – recycles RO reject water • Corn Oil Separation for biodieselPAGE 17CONFIDENTIAL
    16. 16. LEGISLATIVE ISSUES Changes already in effect •VEETC Blenders credit was allowed to expire on January 1, 2012 •Tariff on imported (Brazilian) ethanol also expired on January 1, 2012 •Small Producer Tax Credit expired 1/1/2012PAGE 18CONFIDENTIAL
    17. 17. LEGISLATIVE ISSUES Legislation/regulations in progress •Blend wall – E15 and blender pumps – US Market saturated at 10% ethanol – EPA moving forward with approval process – Ethanol is currently selling for $1/gallon discount to gasolinePAGE 19CONFIDENTIAL
    18. 18. LEGISLATIVE ISSUES • “Indirect Land Use Change” – controversial theory that claims corn used for ethanol in America kicks off a chain reaction that leads to global deforestation. – Forecast models of this theory do not match actual historical data • CARB and LCFS – ethanol industry has won an injunction under interstate commerce clause – California ethanol was treated preferentially – State of California is appealingPAGE 20CONFIDENTIAL
    19. 19. LEGISLATIVE ISSUES • Corn ethanol and Advanced biofuels – Corn ethanol cannot be considered an “advanced” biofuel regardless of carbon intensity under RFS2 rules • RFS2 pathways available to show 20% GHG reduction for RINS • 90% of steam from CHP • 90% raw starch hydrolysis • Corn oil extraction at 1.33 lbs/bu • Wet vs. dry distillers grains (50% or 65% + 1)PAGE 21CONFIDENTIAL
    20. 20. LEGISLATIVE ISSSUES • RFS2 – blending requirements for ethanol and other biofuels – 36B gallons by 2022 – Being targeted for repeal by opponents – 15B cap for corn ethanol • Special targets for advanced biofuels and cellulosic • POET Biorefining – Emmetsburg has broken ground for 20MM gallon co- located cellulosic ethanol refinery using corn residue (Project LIBERTY)PAGE 22CONFIDENTIAL
