Market Conditions Practices
Is the future 5.00 Corn? The corn supply is
tightening
Ethanol Yield of 2.6-2.7 GPB
Large amounts of Steam at higher pressures
Significant need for sulfur or other
sterilization methods
Batch and/or Continuous Processes
Corn Moisture Requirements 12-15
DDG pricing glut due to oversupply and a limited
market
Market Cap for non-Cellulosic subsidies near limit

Is the future 5.00 Corn? The corn supply is

Ethanol Yield of 2.6-2.7 GPB (before 5 solvent)
Crush Margin Ethanol Value 2.65GPB1.51
4.00/Bu Corn Cost (fall delivery)
3.25/Bu Crush Margin 0.75 Not enough for
Overhead with current Co-Product valuation!
Chicago Board of Trade Fuel Ethanol - 1.51,
September Corn - 3.25
Large amounts of Steam at higher pressures
A typical plant requires 31 of steam per gallon
at relatively high pressures.
Significant need for sulfur or other
sterilization method
Creates Process Waste Water that must be
cleaned before disposal or reuse.
7
Many Plants are Still Partially Batch Type
A batch type production facility causes gaps in
production as batches must move as a whole from
stage to stage of the production cycle. This is
time that would be better spent producing more
ethanol in a continuous cycle.
Dry Grind Plant Required to be around 12-15 for
use
This increases the input cost of corn due to
drying prior to arrival at production facility.
DDG pricing glut due to oversupply and limited
market
5 years ago, DDG DDGS were being marketed _at_
1.4X the value of the corn with the starch
removed. 5.80 corn would value the DDGS at
285/ton, but is selling as Corn Gluten Feed _at_
120/ton. DDGS is quoted at 150/ton.
8
Market Cap for non-Cellulosic subsidies near limit
The 2007 Energy Bill limited the number of
Gallons of Ethanol available for subsidies. 2008
was limited to 9 Billion gallons. Per all
industry projections, the US will have over 9
Billion in capacity by the end of 2008 counting
all plants coming online. The growth opportunity
is in Advanced Biofuel Production.

Module I II Bio-Grind / Increased Productivity
The LAI-PRO Bio-Grind Process is a continuous
cycle based on the fundamentals of continuous
corn steeping in conjunction with advanced kernel
separation and process modifications for greater
ethanol yields and the removal of valuable
co-products before fermentation.
This process can be retrofit to any existing
Ethanol Facility or incorporated into the design
of a new plant be it, Wet or Dry Mill.

BENEFITS
Use High Moisture Corn Directly From the Field at
Harvest With No Drying Charge
Improve Net Corn Costs By Extracting Quality
Co-Products When Economical or When Market
Conditions Exist
Operate with NO Process Waste Water Discharges
Take Advantage of Continuous Process Savings to
Minimize Equipment, Construction, Operation, and
Control Costs
Sanitize or Sterilize the Scrubber and Wash Water
With Recycle Steam Without Affecting the Pasting
of the Corn
Utilize the New Recyclable Raw Starch Hydrolysis
Enzyme Technology
11
BENEFITS (Continued)
Control Contaminant Growth Propagation Without
Sulfur Compounds
Feed Fermenters 40 Soluble Solids - Utilize Very
High Gravity Technology
Increase Fermentation Alcohols to 18 or Higher
Once Yeast Strains Avail.
Improve Starch Utilization and Ethanol Yield
Save Considerable Energy Due to Lower Viscosities
Avoid the Glut of DDG and DDGS in the Marketplace
Become Prepared For When New Fiber Fermentation
Technology Becomes Economical to Incorporate
Other Biomass Feed Stocks
