The document summarizes information about the Poet Biorefining plant in Laddonia, Missouri. It discusses the plant's production capacity of 60 million gallons per year of ethanol and 160,000 tons per year of dried distillers grains. It also describes the plant's water recycling processes and innovations to reduce water usage. Finally, it outlines several legislative issues impacting the ethanol industry, including the renewable fuel standard and incentives for corn and advanced biofuels.

3. 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 system

4. 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)

10. POET BIOREFINING – LADDONIA WATER USE
PAGE 10
CONFIDENTIAL

11. 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
2011
PAGE 11
CONFIDENTIAL

12. 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 water

13. POET Biorefining – Laddonia Water Use

14. 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?

CONFIDENTIAL

15. 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)

16. 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 profitability

17. 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 biodiesel

18. 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 1/1/2012

19. 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 gasoline

20. 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 appealing

21. 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 21
CONFIDENTIAL

22. 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)
