NEW DELHI — India has launched one of the world’s first commercial-scale projects to convert cattle waste into compressed biogas (CBG), a renewable fuel now powering vehicles across multiple states. The initiative, backed by government policy and private sector investment, aims to address both agricultural waste management and the country’s growing energy demand while reducing greenhouse gas emissions.
Officials and industry leaders say the program has already processed over 1.2 million tonnes of cattle dung since its pilot phase began in 2025, producing more than 50,000 tonnes of CBG annually. The fuel, chemically identical to compressed natural gas (CNG), is being blended into India’s existing CNG infrastructure and used in public transport fleets, commercial trucks, and private vehicles.
The project is anchored in the government’s Sustainable Alternative Towards Affordable Transportation (SATAT) scheme, launched in 2018 and expanded in 2024. Under SATAT, the Ministry of Petroleum and Natural Gas has set a target of establishing 5,000 CBG plants by 2030, with an annual production capacity of 15 million tonnes. As of March 2026, 1,127 plants have been commissioned, according to ministry data, with 342 currently operational.
The biogas is produced through anaerobic digestion, a process in which microorganisms break down organic waste in oxygen-free tanks. The resulting methane is purified, compressed, and transported via pipelines or tankers to fuel stations. The remaining digestate, a nutrient-rich byproduct, is sold as organic fertilizer, creating an additional revenue stream for farmers.
In Gujarat, one of the leading states in the initiative, a 10-tonne-per-day CBG plant in Anand district processes waste from 20,000 cattle daily. The plant, operated by a joint venture between a state-owned energy company and a private agri-tech firm, supplies fuel to 15 CNG stations across the region. Local dairy cooperatives, which collect dung from farmers, receive payments of up to ₹2,000 per tonne, providing a new income source for rural households.
Environmental experts say the program could significantly reduce methane emissions, a potent greenhouse gas 28 times more effective than carbon dioxide at trapping heat over a 100-year period. India’s livestock sector, the world’s largest with over 300 million cattle, emits an estimated 15–20% of the country’s total methane output. By capturing and converting this waste, the government estimates potential annual emissions reductions of up to 50 million tonnes of CO₂ equivalent.
The initiative also aligns with India’s broader energy transition goals. The country has committed to achieving 50% non-fossil fuel-based electricity capacity by 2030 and net-zero emissions by 2070. While solar and wind dominate India’s renewable energy portfolio, biogas offers a decentralized, baseload-compatible solution that leverages existing agricultural infrastructure.
However, challenges remain. Industry analysts note that scaling up production requires consistent feedstock supply, which depends on farmer participation and efficient collection networks. Some rural communities have reported logistical hurdles in transporting dung to processing centers, particularly during monsoon seasons. Additionally, the high capital cost of biogas plants—typically ₹25–35 crore for a 10-tonne-per-day facility—has slowed private investment, despite government subsidies covering up to 40% of project costs.
Regulatory hurdles have also emerged. In 2025, the Ministry of Environment, Forest and Climate Change introduced stricter emission standards for biogas plants, requiring continuous monitoring of methane leaks. Compliance has added operational costs, prompting some smaller operators to delay expansion plans.
Despite these obstacles, the government has accelerated policy support. In January 2026, the Cabinet approved a ₹10,000 crore viability gap funding scheme to incentivize CBG production, with a focus on states with high cattle populations, including Uttar Pradesh, Rajasthan, and Madhya Pradesh. The Reserve Bank of India has also classified CBG projects as priority sector lending, easing access to credit for entrepreneurs.
Market analysts say the long-term success of the program hinges on integration with India’s broader energy ecosystem. The country’s largest oil marketing companies—Indian Oil Corporation, Bharat Petroleum, and Hindustan Petroleum—have committed to purchasing CBG at fixed prices under long-term offtake agreements, ensuring stable demand. Meanwhile, automakers such as Tata Motors and Mahindra & Mahindra have begun offering bi-fuel vehicles capable of running on both CNG and CBG.
Analysis:
India’s cattle-to-fuel initiative represents a rare convergence of agricultural policy, energy security, and climate action. Unlike many renewable energy projects that rely on imported technology or raw materials, biogas production leverages India’s vast domestic livestock resources, reducing dependence on foreign energy imports. The program also offers a scalable model for other developing nations with large cattle populations, such as Brazil and Ethiopia.
However, the economic viability of CBG remains contingent on sustained government support. While the fuel is cost-competitive with CNG in some regions—priced at ₹60–70 per kg compared to ₹75–85 for conventional CNG—its production costs are higher due to feedstock collection and plant maintenance expenses. Without subsidies or carbon credits, industry experts warn that CBG may struggle to compete with cheaper fossil fuels in the short term.
The social impact of the program is equally significant. By formalizing dung collection and processing, the initiative has created thousands of rural jobs, particularly for women in dairy cooperatives. In states like Gujarat and Punjab, self-help groups have established micro-enterprises to aggregate and transport cattle waste, earning monthly incomes of ₹10,000–15,000.
Yet, the environmental benefits may be overstated if methane leakage from plants and pipelines is not rigorously controlled. A 2025 study by the Council on Energy, Environment and Water (CEEW) found that even small leaks—less than 3% of total production—could negate up to 30% of the climate benefits of biogas. The government’s recent regulatory push to monitor emissions is a step in the right direction, but enforcement remains uneven across states.
Looking ahead, the success of India’s biogas revolution will depend on three factors: technological innovation to reduce production costs, policy consistency to attract private investment, and community engagement to ensure steady feedstock supply. If these challenges are met, cattle waste could become a cornerstone of India’s renewable energy portfolio, transforming a long-standing environmental liability into a sustainable asset.
