According to India's National Policy on Biofuels, which of the following can be used as raw materials for the production of biofuels ? 1. Cassava 2. Damaged wheat grains 3. Groundnut seeds 4. Horse gram 5. Rotten potatoes 6. Sugar beet Select the correct answer using the code given below:
- A.1, 2, 5 and 6 only
- B.1, 3, 4 and 6 only
- C.2, 3, 4 and 5 only
- D.1, 2, 3, 4, 5 and 6
Correct answer
Explanation
The correct answer is A, 1, 2, 5 and 6 only. The policy allows cassava, damaged wheat, rotten potatoes and sugar beet, but not groundnut seeds or horse gram.
The National Policy on Biofuels, 2018 widened the raw materials for ethanol beyond sugarcane molasses. It allows sugarcane juice, sugar-containing materials such as sugar beet and sweet sorghum, starch-containing materials such as corn and cassava, and damaged food grains such as wheat and broken rice, along with rotten potatoes, that are unfit for human eating. Surplus food grains may be used with the approval of the National Biofuel Coordination Committee. The aim is to raise ethanol blending in petrol while giving farmers a market for produce that would otherwise be wasted.
B is wrong because groundnut is an edible oilseed and horse gram a pulse, neither listed as a feedstock. C is wrong because it adds those two and leaves out cassava and sugar beet. D is wrong because not all six are allowed.
Exam tip: 2018 biofuel policy feedstocks: sugar beet, sweet sorghum, cassava, corn, damaged grains, rotten potatoes.
