What Happened
- Gujarat has allocated ₹60 crore in its 2026–27 state budget to expand Bio-CNG plant infrastructure through cooperative milk production societies, building on the success of the Banas Dairy model.
- Banas Dairy (Banaskantha Cooperative) operates Bio-CNG plants that convert cow dung and organic waste into compressed biogas and organic manure — the model is estimated to reduce 6,750 tonnes of CO2 equivalent annually while generating ~₹12 crore in annual revenues per plant.
- Each plant produces approximately 1,800 kg of compressed biogas and 25 metric tonnes of solid organic manure daily; farmers receive ₹1 per kg for cow dung, providing supplementary income to 400–450 farming families per plant.
- The model is now being replicated across nearly 15 states through the joint efforts of the Union Ministries of Jal Shakti and Cooperation.
- The initiative aligns with the Satat scheme (2018) — the government's flagship programme for Bio-CNG/Compressed Biogas (CBG) production from biomass — and the government's push to reduce fossil fuel dependence in the transport and cooking fuel sectors.

Compressed Biogas (CBG) / Bio-CNG: Production and Policy Framework
Biogas is produced through anaerobic digestion of organic matter (manure, agricultural residue, food waste, sewage sludge) by microorganisms in the absence of oxygen. The primary output is a mixture of methane (55–65%) and carbon dioxide (35–45%), along with hydrogen sulphide and water vapour. When biogas is purified to remove CO2 and impurities, and compressed, it becomes Compressed Biogas (CBG) or Bio-CNG — chemically equivalent to Compressed Natural Gas (CNG) and usable in existing gas infrastructure without modification. Unlike biogas used directly for cooking, CBG can be bottled, transported, and sold through the commercial CNG network.
- Feedstocks: cattle dung, press mud (sugarcane waste), agricultural stubble, municipal solid waste, sewage — diverse and abundant in rural India
- Energy content: CBG has calorific value ~52 MJ/kg, comparable to natural gas
- By-product: bio-fermented organic manure (slurry) — a high-value fertiliser that replaces chemical inputs
- Difference from biogas: biogas is raw, low-pressure, used locally; CBG is purified, compressed to ~200 bar, tradeable commodity
- India's estimated CBG potential: 60 million tonnes per year from all available biomass (MoPNG estimate)
Connection to this news: The Banas model captures this full value chain — converting waste to energy, generating organic manure, paying farmers for dung feedstock, and selling CBG into the transport fuel market — making it an integrated rural circular economy model.
Satat Scheme and the Sustainable Alternative Towards Affordable Transportation
Launched in 2018 by the Ministry of Petroleum and Natural Gas (MoPNG), the Satat (Sustainable Alternative Towards Affordable Transportation) scheme aims to promote Bio-CNG as an alternative transport fuel. Under Satat, the government targets setting up 5,000 CBG plants producing 15 million tonnes of CBG annually by 2023–24 (a target that has seen slower-than-planned progress). Oil Marketing Companies (IOMACs — IOC, BPCL, HPCL) are mandated to purchase CBG from entrepreneurs at agreed prices and market it through their CNG stations.
- Launch: October 2018
- Target: 5,000 CBG plants, 15 MMT/year CBG production by 2023–24 (revised timelines ongoing)
- Mechanism: government guarantees offtake through OMCs; entrepreneur sets up plant and sells CBG at pre-agreed price
- Finance: plants eligible for priority sector lending; additionally, MNRE provides capital subsidy under some schemes
- CBG blending mandate: government is exploring mandating a minimum % CBG blending in CNG supplied at filling stations to create assured demand
- Progress (as of 2025): ~600 plants operational — far below the 5,000 target, indicating execution challenges
Connection to this news: Gujarat's ₹60 crore allocation and the Banas Dairy model represent a cooperative-sector entry point that may accelerate CBG deployment where private entrepreneurs have struggled — leveraging existing dairy infrastructure, farmer networks, and cooperative management systems.
Cooperative Model in Agriculture and Dairy: India's Amul Lesson
India's cooperative dairy sector — anchored by the Gujarat Cooperative Milk Marketing Federation (GCMMF), the Amul brand — is a global model of farmer-owned enterprise. Cooperatives aggregate small producers, eliminate middlemen, provide assured market access, and return value to members. The cooperative model is structurally suited to Bio-CNG because: (a) it already aggregates dung as a by-product of dairy operations; (b) members have established trust and governance structures; (c) cooperatives have capital-raising capacity; and (d) organic manure can be supplied back to member-farmers, closing the circular economy loop.
- Amul model (Operation Flood, 1970s): transformed India from a milk-deficit to the world's largest milk producer; 36 million farmer members
- National Dairy Development Board (NDDB): apex body promoting dairy cooperatives; has partnered with Banas Dairy for CBG plant establishment
- Banas Dairy: largest single milk-producing cooperative in India; processes ~7+ million litres/day
- Three-tier structure: village dairy cooperative society → district milk union → state federation (e.g., GCMMF)
- Suzuki Motor Corporation (India) partnership: collaborated with NDDB and Banas Dairy to set up dung-based CBG plants in Banaskantha district
Connection to this news: The expansion of the Banas Bio-CNG model through cooperative milk societies is effectively applying the Amul logic to the energy sector — using cooperative infrastructure to achieve scale, farmer participation, and economic viability simultaneously.
