Uses existing biofuels value chainIs easily added to gasoline used in
existing vehicles Is added to the fungible fuel pool using
existing infrastructure to enhance sustainable growth
Is used in reasonable blend concentrations and requires no compromise in fuel specifications
Offers good value to consumers without performance compromise
Enhances the use of incumbent biofuels

PIPELINE
• BETTER FUEL CONSUMPTION• POTENTIAL FOR HIGHER BLEND LEVELS WITHOUT VEHICLE MODIFICATION• LOW VAPOR PRESSURE ALLOWS FOR POTENTIAL INCREASE IN ETHANOL BLENDING• PROMOTES USE OF EXISITING RETAIL PUMPS AND STORAGE
• LIMITED WATER ABSORPTION• FUNGIBLE BLENDING COMPONENT• LOWER VAPOR PRESSURE AIDS REFINERS• LESS CORROSIVE • UTILIZE EXISTING INFRASTRUCTURE
• SAME AGRICULTURAL FEEDSTOCKS • UTILIZE ETHANOL PRODUCTION ASSETS
Biobutanol: Provides Greater Options for Sustainable Renewable Fuels
