Which of the following best describes the primary objective of the GOBARdhan scheme?

To promote the production of Compressed Biogas and manage organic waste for sustainable energy.

To incentivize the export of agricultural residues to international markets.

To mandate the use of solar power in all rural sugar mills.

To provide direct cash subsidies to farmers for purchasing chemical fertilizers.

Regarding the feedstock used for Compressed Biogas (CBG) production, which statement is correct?

Agricultural residues like paddy straw generally yield 10% or more gas.

Cattle dung is the most easily transported feedstock due to its low moisture content.

Press mud is a non-perishable feedstock that can be stored for years.

Paddy straw has a lower gas yield compared to cattle dung.

Compressed biogas supply chain challenges

The topic covers the GOBARdhan scheme, a flagship government policy, and addresses critical supply chain and circular economy challenges directly relevant to GS3 energy and agricultural infrastructure questions.

Notes

Compressed Biogas (CBG) production is currently scaling up, with 1,302 functional plants and 256 under construction.
Government targets for CBG blending with CNG and PNG are 3% in FY27, followed by 4% and 5% in subsequent years.
The GOBARdhan scheme, revamped with a ₹23,731-crore outlay, aims to boost CBG growth and will remain in place until 2036.
Primary feedstocks include press mud (sugarcane residue), agricultural residues (paddy/wheat straw), and animal manure.
Logistical challenges: Press mud and cattle dung require proximity (approx. 25-km radius) due to high moisture and perishability; paddy straw requires specialized baling and storage.
Seasonal constraints: Press mud is limited by the 4-5 month sugar milling season; paddy straw collection is restricted to a 15-day window post-harvest.
Environmental considerations: Long-distance transport of feedstock can negate CBG's environmental benefits by increasing fossil fuel consumption.
Supply chain model: Aggregators are essential to bridge the gap between farmers and plants, facilitating collection and managing legal/social complexities.
Circular economy: Bio-slurry, a byproduct of CBG production, serves as organic fertilizer, creating a link between energy production and agriculture.
Technical efficiency: Gas yield is approximately 6% for cow dung and 10% or more for agricultural residues; plants are recommended to be multi-feedstock capable.

Part of a longer story

This is day 2 of 3 in Implementation and expansion of the GOBARdhan scheme, which has been running since 7 August 2026. Reading it whole is usually worth more than reading today alone — the exam asks how something developed.
