Biofuel production from sweet sorghum in Florida
• Stress tolerant (drought, heat) and limited input requirements compared to sugar cane
• Minimal competition with food production• Ideal crop for transition from sugar-based to
lignocellulosic biofuels• Compatible with sugarcane production• 7,000 L ethanol per hectare from juice
Next-generation sweet sorghums: Sustainable production of fuels and chemicals from juice and bagasse
