Global driver is need for low cost / low carbon products
Competitive advantage driven by lowest cost of production
Market OpportunityButanol Today:
Chemicals
• Derived from multiple feedstocks
• Superior properties to alternate biofuels
• $50bn p.a. worldwide biofuel market growing 7.5% p.a.
• Regulations requiring biofuel blends guarantees the market (e.g. EU / US)
• Derived from petroleum
• Used for paints, coatings, resins, polymers, and solvents
• $4.3bn p.a. worldwide chemical market, growing at 4% p.a.
• Bio-butanol is a direct substitute
Butanol tomorrow: Biofuels

Butanol: A Superior Biofuel
• Butanol is superior to ethanol:
– Higher energy density and lower vapour pressure
– Better compatibility with existing fuel distribution and vehicle engines
• Also superior to biodiesel
– Cold weather properties and sustainable feedstocks
• Simple market entry through blending in gasoline or diesel

Existing Butanol Producers
e.g. Chinese biobutanol
Biofuel Producer e.g. Cellulosic, ethanol retrofit
- “Bolt on / retrofit ” - Improved economics - Limited capex required
- Poor plant economics- Limited uses for waste- Limited fermentation / process understanding
Plant Enhancement /Retrofit
e.g. Sugar mill / ethanol producer
