Sucrose Fermentation into Alcohol is the cornerstone technology enabling direct bioethanol production from sugar crops.

WHAT MAKES THIS TECHNOLOGY DISTINCT?
Unlike starch-based feedstocks (corn, wheat) that require costly enzymatic saccharification, sugar crops like sugarcane and sweet sorghum contain directly fermentable sugars in their stems. This enables:
✅ Simpler process configuration – No liquefaction or saccharification steps
✅ Faster fermentation – 8-12 hours vs. 48-72 hours for starch-based processes
✅ Lower CAPEX/OPEX – Eliminated enzyme costs and reduced equipment complexity
✅ Superior sustainability – 70-90% GHG reduction vs. gasoline; energy self-sufficiency via bagasse cogeneration
