The Path to Ethanol from Cellulose
Biotech enzyme
Feedstock Collection

• Biotechnology Treatment
• Enzymes break
• cellulose into sugars
• Ferment sugars to
• ethanol

• Downstream
• Ethanol
• recovery
• shipment

Pretreatment Pulverize or grind feedstock to
release cellulose

Biomass Potential

• More than 1 billion tons of agricultural
  residues and dedicated energy crops could be
  sustainably harvested by 2030 for biofuels
  production in the United States alone.2007

Average Corn Yield Up Since 1996 Introduction of
Biotech Corn
1996-2005 137.7 bu/acre
1986-1995 115.15 bu/acre

• Biotechnology Innovation
• Produces Food AND Fuel

Yield growth of just 2 bushels per acre per year
results in an additional 144 million bushels .
That additional corn could produce more than 403
million gallons of ethanol.
10-year average 72 million harvested acres
14
Abundant Cellulose Sources

• Corn Stover
• Rice Straw Hulls
• Wheat Barley Straw
• Switch Grass
• Saw Dust Wood Chips
• Sugar Cane Waste (bagasse)
• Grass Clippings
• Other Agricultural Residues
• Waste Paper Other Trash

A Global Opportunity
16
Creating the Future We Want

• Continued deployment of industrial and ag biotech
  improvements
• Supportive governmental policies
• The use of grain and cellulosic biomass
• Innovative and sustainable farming practices
• Farmers participating in the value chain
• The evolution of biorefineries to make multiple
  products
