1. Rising crude oil prices.
2. Growth in China, India and Russia increasing demand for fuels.
3. Increasing environmental awareness and concerns among the public, driving the desire for a sustainable lifestyle.
4. Technology developments (such as methods for enzyme optimization) that allow for discovery, innovation and growth of the biofuels industry.
