Concept & Option Breakdown

Standard Reference Verified

Under the National Policy on Biofuels (2018), the scope of permissible raw materials for ethanol production was expanded to include sugar-containing materials (sugar beet, sweet sorghum, sugarcane juice), starch-containing materials (cassava, corn), and surplus/damaged food grains unfit for human consumption (damaged wheat grains, broken rice, rotten potatoes). Edible food legumes and primary oilseeds like groundnut seeds and horse gram are excluded from raw material lists for ethanol.
