Agricultural waste holds the key to India’s clean energy future
Crop residue (agricultural waste), currently a major contributor to seasonal air pollution through open burning, is being highlighted as an underused clean-energy feedstock
Converting residue into compressed biogas (CBG) and other bioenergy forms is presented as a way to simultaneously address rural incomes, energy security, and India's climate commitments
The opportunity is described as contingent on policy and infrastructure — such as collection logistics, storage, and offtake mechanisms — catching up with the technical potential
Existing national schemes for biogas and biofuels are cited as the framework through which this shift could be scaled
SATAT Scheme and Compressed Biogas (CBG)
SATAT (Sustainable Alternative Towards Affordable Transportation) is a Ministry of Petroleum and Natural Gas scheme launched to promote compressed biogas as an alternative, indigenously-produced transport and industrial fuel produced from agricultural residue, cattle dung, sewage, and municipal solid waste.
Key Details
- SATAT launched 1 October 2018 by the Ministry of Petroleum and Natural Gas
- Original scheme target: setting up 5,000 CBG plants by 2025, with an eventual annual production target in the range of 15 million tonnes of CBG
- CBG is chemically similar to CNG and can be blended into the City Gas Distribution (CGD) network or used directly as vehicle fuel, priced in reference to CNG
- Oil marketing companies (IOCL, HPCL, BPCL) are the designated offtake entities that purchase CBG from entrepreneurs under long-term agreements
SATAT is the principal national vehicle through which crop residue can be converted from a disposal problem into a monetised feedstock, since it guarantees entrepreneurs an offtake buyer for CBG produced from agricultural waste.
Stubble Burning and the Commission for Air Quality Management (CAQM)
Stubble (crop residue) burning, especially paddy straw in Punjab, Haryana, and western UP after the kharif harvest, is a major contributor to seasonal air pollution in the National Capital Region. The Commission for Air Quality Management in NCR and Adjoining Areas Act, 2021 created a dedicated statutory body to coordinate air-quality action across states, superseding the earlier, less-effective Environment Pollution (Prevention and Control) Authority (EPCA).
Key Details
- CAQM Act enacted 12 August 2021; establishes CAQM as a statutory body covering Delhi and adjoining areas in Punjab, Haryana, Rajasthan, and Uttar Pradesh
- CAQM has issued directives to states for equipment support (e.g., happy seeders), enabling residue-procurement infrastructure, and storage facilities as alternatives to burning
- CAQM's powers include issuing binding directions to state governments and imposing penalties for non-compliance
- Complements the National Green Tribunal's earlier orders and the National Clean Air Programme (NCAP, 2019) targets for particulate matter reduction
Building bioenergy offtake infrastructure (like CBG plants) for crop residue is presented as a market-based complement to CAQM's regulatory directives — converting the same residue that would otherwise be burned into a saleable energy input reduces the economic incentive for farmers to burn it.
National Bioenergy Programme and Biofuel Policy
The Ministry of New and Renewable Energy (MNRE) runs schemes supporting energy generation (biogas, bio-CNG, power) from agricultural and other biomass waste, complementing the transport-fuel-focused SATAT scheme. These sit within the broader National Policy on Biofuels, which sets ethanol-blending and biofuel-feedstock targets.
Key Details
- The National Policy on Biofuels, 2018 (amended 2022) advanced India's ethanol blending target of 20% (E20) in petrol; a related but distinct track from CBG
- MNRE's bioenergy programme supports biogas/bio-CNG/power projects using agricultural residue and other organic waste as feedstock, distinct from the Ministry of Petroleum's SATAT
- India's technical potential for bio-CNG has been estimated at tens of millions of tonnes annually, far exceeding current production levels [Unverified]
The article's framing of "policy and infrastructure catching up with opportunity" reflects the gap between MNRE/SATAT's technical feedstock potential and the actual installed CBG capacity, largely attributed to collection-logistics and capital-cost barriers rather than lack of raw material.
- SATAT scheme launched: 1 October 2018, Ministry of Petroleum and Natural Gas
- Original SATAT target: 5,000 CBG plants by 2025
- CAQM Act enacted: 12 August 2021, covering Delhi-NCR and adjoining states (Punjab, Haryana, Rajasthan, UP)
- National Policy on Biofuels: 2018, amended 2022; E20 ethanol-blending target
- CBG is compositionally similar to CNG and can be supplied through the City Gas Distribution network
- Key feedstocks for CBG: agricultural residue, cattle dung, municipal solid waste, sewage
