What Happened

A policy analysis published in June 2026 argues that paddy straw-based Compressed Biogas (CBG) projects deserve dedicated special funding and viability gap support to make them commercially viable and scale up rapidly — converting a recurring agricultural pollution crisis into a clean energy opportunity.
Punjab generates approximately 16.1 million tonnes of paddy straw annually, while Haryana adds approximately 4.04 million tonnes; a significant proportion of this is burned in the fields, releasing particulate matter, carbon dioxide, carbon monoxide, and nitrogen dioxide into the atmosphere — driving Delhi's catastrophic winter air quality deterioration.
The Punjab Energy Development Agency (PEDA) has allocated 57 CBG projects across the state with a combined capacity of 815.68 Tonnes Per Day (TPD), of which only 6 are operational (107.48 TPD); once all are commissioned, the projects will collectively consume 2.80 million tonnes of paddy straw annually — still a fraction of the total.
The key barrier is commercial viability: paddy straw is a difficult feedstock — it has high silica content, low bulk density, and seasonal availability — making it more expensive to process than other organic waste. Without special viability gap funding (VGF) or feedstock procurement support, projects struggle to attract private investment.
The article calls for a dedicated funding window for paddy straw-based CBG, distinct from the broader SATAT and GOBAR-Dhan schemes, to address the unique techno-economic challenges of this feedstock.
India's broader SATAT scheme has issued 1,094 active Letters of Intent (LoIs) for CBG plants but only 108 have been commissioned as of July 2025 — far short of the initial target of 5,000 plants by 2023-24.

Compressed Biogas (CBG) — Technology and Role in India's Energy Mix

Compressed Biogas (CBG) is biogas (primarily methane) produced through anaerobic digestion of organic material — agricultural residue, cattle dung, food waste — that is then purified and compressed to match the energy specifications of Compressed Natural Gas (CNG). CBG is a renewable, carbon-neutral fuel that can be used directly in CNG-fuelled vehicles, cooking, and industrial applications. The by-product of CBG production is bio-slurry (fermented organic matter), a rich organic fertilizer that reduces chemical fertilizer use.

Biogas composition: ~60% methane (CH₄) + CO₂ + trace gases
CBG specification: after purification and compression, meets CNG quality standards (>90% CH₄)
Energy parity: 1 kg of CBG ≈ 1 kg of CNG in energy terms
By-product: bio-slurry / fermented organic manure — reduces chemical fertilizer demand
Paddy straw challenge: high silica, low bulk density, seasonal supply → higher processing cost vs. cattle dung or food waste

Connection to this news: The call for special funding recognises that paddy straw-based CBG faces feedstock-specific challenges that generic CBG policy instruments (designed around cattle dung) do not adequately address.

GOBAR-Dhan Scheme and SATAT Initiative — Policy Architecture

The GOBAR-Dhan scheme (Galvanising Organic Bio-Agro Resources Dhan) was launched under the Swachh Bharat Mission (Grameen) to convert cattle dung, agricultural and organic waste into biogas/CBG and compost, targeting rural entrepreneurs, Gram Panchayats, and cooperatives. The SATAT (Sustainable Alternative Towards Affordable Transportation) initiative, launched by the Ministry of Petroleum and Natural Gas in October 2018, focuses specifically on CBG for transportation fuel — with Oil Marketing Companies (OMCs) as mandated offtakers for CBG produced by registered plants.

GOBAR-Dhan: launched 2018 under Swachh Bharat Mission Grameen; targets 700 projects; Ministry of Jal Shakti nodal ministry
SATAT: launched October 2018; nodal ministry: Ministry of Petroleum and Natural Gas; OMCs (IOCL, BPCL, HPCL) are mandated CBG offtakers
Central Financial Assistance under MNRE: ₹4 crore per 4,800 kg/day CBG produced (up to ₹10 crore per project)
Market Development Assistance for organic fertilizer by-product: ₹1,500 per MT
CBG pricing (revised May 2025): 85% of average CNG retail selling price (up from 80%)
Active LoIs under SATAT: 1,094 (as of July 2025); commissioned plants: 108 — implementation gap is severe

Connection to this news: The gap between LoIs (1,094) and commissioned plants (108) under SATAT illustrates exactly why paddy straw-based CBG needs additional targeted support — the existing scheme's financial incentives are insufficient to make the more challenging paddy straw feedstock commercially viable.

Paddy Straw Burning — Environmental Crisis and Policy Failures

Paddy straw burning in Punjab and Haryana after the kharif harvest (October–November) is one of the major contributors to Delhi's annual air quality emergency. Stubble fires release PM2.5, PM10, carbon monoxide, nitrogen dioxide, and black carbon. Delhi's PM2.5 levels exceed 300–400 on the AQI scale most days in November during peak burning season. Previous policy responses — subsidising Happy Seeders (straw mulching machines), fining farmers, banning burning — have had limited success because the underlying economics of straw disposal remain unresolved.

Punjab paddy straw generated: ~16.1 million tonnes annually
Haryana paddy straw: ~4.04 million tonnes annually
Paddy straw burned (Punjab, 2023-24): approximately 8.9 million tonnes (Punjab + Haryana combined)
Punjab + Haryana contribute to: ~48% of total paddy burning emissions in India
Delhi's AQI (November, peak burning season): frequently above 300–400 (Severe/Hazardous category)
PM2.5: particulate matter below 2.5 microns — penetrates deep into lungs; major public health risk
Previous policy tools: Happy Seeder subsidy, Crop Residue Management scheme, penalties — limited uptake due to economics

Connection to this news: CBG offers a market-based solution to stubble burning — by creating economic value for paddy straw as feedstock, it removes the farmer's incentive to burn. Special funding for paddy straw CBG is thus simultaneously a clean energy policy and an air quality intervention.

Bioenergy Policy and National Bioenergy Programme

India's National Bioenergy Programme (2021–26) consolidates multiple schemes — waste-to-energy, biomass power, biogas — under a single framework administered by the Ministry of New and Renewable Energy (MNRE). The programme targets increased share of bioenergy in India's renewable energy mix, aligned with the broader goal of 500 GW of non-fossil fuel capacity by 2030 and net-zero by 2070.

National Bioenergy Programme: launched 2021–26 by Ministry of New and Renewable Energy (MNRE)
Focus areas: biogas/CBG, biomass power and cogeneration, waste-to-energy
India's renewable energy target: 500 GW of non-fossil fuel capacity by 2030
Paddy straw as biomass: classified as agricultural residue; eligible under MNRE bioenergy support schemes
Viability Gap Funding (VGF): a mechanism where the government bridges the gap between project cost and commercially viable returns; widely used in solar, roads, and ports — the article argues it should be extended specifically to paddy straw CBG

Connection to this news: The policy argument is that paddy straw CBG deserves VGF treatment — similar to early-stage solar and wind projects — because it provides multiple public goods (clean energy, air quality, farmer income) that the private market alone will not adequately fund.
