India is the fourth largest producer of ethanol in the world, producing it primarily through the fermentation of molasses, a byproduct of sugarcane processing. Sugarcane production is concentrated in certain states like Uttar Pradesh, Maharashtra, and Tamil Nadu. In order to increase ethanol production, the Indian government is providing subsidies and mandating blending quotas. Sugar companies are expanding ethanol production capacity by building 30 new ethanol plants in 2007 with the goal of using more sugarcane directly for ethanol production rather than relying on molasses.
