Industrial biotechnology uses enzymes and engineered microorganisms to convert renewable biomass into fuels, power, and chemicals. This process is analogous to petroleum refineries and enables the development of biorefineries. Genencor is a leader in industrial biotechnology and has developed enzymes that enable the conversion of starch and cellulosic feedstocks into biofuels and biochemicals. Genencor's enzymes have helped advance biorefineries from first generation starch-based ethanol to future generations using lignocellulosic biomass as a sustainable feedstock.

6. Biorefinery:
“A biorefinery is a facility that converts waste
biomass into fuels, power, and chemicals.
The biorefinery concept is analogous to today's
petroleum refineries, which produce multiple fuels
and products from petroleum.”

24. Genencor®: on the Road to
Sustainable Biorefineries
The biobased economy is here and its growing
• ~5-10% of chemicals will be bio-based by 2012
(McKinsey 2006)
High oil prices and environmental concerns are key
factors fueling the biobased economy
Innovations in enzyme processing are enabling the
development of sustainable integrated systems for
biomass processing to fermentable sugars
New business models / Strategic relationships and
Technology Integrators will speed Biorefinery
development
Biobased processes will continue to deliver Strategic
alternatives to petrochemicals
24

25. Our Vision of the Biobased Economy
We envision a future where biotechnology
fulfills many unmet needs…
 In development and deployment of
industrial enzymes
 In the production of fuels, chemicals and
materials
We envision a future where biotechnology
helps create sustainable industrial
activities
We envision a future where biorefineries
take their place alongside oil refineries
We aspire to be recognized as a leader in
world-changing technology solutions.
