How the exam will ask it
प्रीलिम्स
- Biogas produced by anaerobic digestion of organic waste consists mainly of methane and carbon dioxide.
- Compressed biogas (CBG) can substitute CNG as a vehicle fuel and for piped gas.
- GAIL (India) Limited is a public sector undertaking under the Ministry of Petroleum and Natural Gas.
- Under the SATAT initiative, oil marketing companies offer to purchase CBG from entrepreneurs.
मेन्स
GS-III (Environment, Energy): Rising urban municipal solid waste and landfill pressure in cities like Bengaluru call for scientific processing under the Solid Waste Management Rules. Waste-to-biogas plants cut landfill methane, create clean fuel and support the GOBARdhan and SATAT goals. Way forward: strict source segregation, assured offtake and pricing for CBG, and use of the digestate as organic manure.
Quick recall
Answer before you reveal
Consider the following statements about the Cabinet-approved rabi fertiliser subsidy of ₹62,370 crore:
- The subsidy rate on nitrogen has been doubled.
- The subsidy rate on phosphorus has been reduced.
Which of the statements given above is/are correct?
- 1 only
- 2 only
- Both 1 and 2
- Neither 1 nor 2
उत्तर देखें
उत्तर: A — Correct: 1 only — the nitrogen subsidy has been doubled, while phosphorus was raised, not cut, so only statement 1 holds. • 2 only — wrong: statement 2 is false because the phosphorus subsidy rate was raised by 25 per cent. • Both 1 and 2 — wrong: statement 2 is false, since phosphorus support went up by 25 per cent. • Neither 1 nor 2 — wrong: statement 1 is true — the nitrogen rate was doubled.
