The Union Cabinet has approved a revamped with a ₹23,731 crore outlay to accelerate (CBG) production. While the government provides a stable framework for offtake, experts highlight that establishing an efficient supply chain for procuring, storing, and managing feedstock—such as press mud, agricultural residues, and animal manure—is the next critical hurdle for scaling the CBG ecosystem.
The economic viability of Compressed Biogas plants hinges significantly on the supply chain logistics of securing feedstock. Unlike conventional fossil fuels with established infrastructure, biomass feedstocks face unique challenges like seasonality, perishability, and low energy density. For instance, press mud (a byproduct of sugar processing) requires sourcing within a 25-km radius due to high moisture and temporary availability. The article highlights an aggregator-based model as a solution to bridge the gap between farmers and CBG plants, overcoming social reluctance towards legally binding contracts. Furthermore, establishing CBG plants designed for a diversified feedstock mix enhances resilience against seasonal fluctuations and improves bargaining power, transforming waste streams into economically valuable energy assets. This aligns with the broader goals of a circular economy, turning agricultural residue from a disposal problem into an income source for rural communities.
Scaling up Compressed Biogas production is central to India's energy transition and climate change mitigation strategies, offering a dual benefit of waste management and renewable energy generation. The use of agricultural residues, particularly paddy and wheat straw, directly addresses the persistent problem of stubble burning, which severely degrades air quality in Northern India during winter months. However, the environmental benefits must be carefully calculated against the carbon footprint of transportation; long-distance transport of bulky feedstock can negate the emissions saved by using CBG. Additionally, the byproduct of CBG production, bio-slurry, serves as a potent organic fertilizer. Returning this slurry to farmers promotes sustainable agriculture by improving soil health and reducing reliance on chemical fertilizers, thereby closing the ecological loop and contributing to sustainable land management practices.
The revamped GOBARdhan scheme (Galvanizing Organic Bio-Agro Resources Dhan) reflects a targeted policy intervention to shift India towards a gas-based economy and reduce import dependence on crude oil. While the government has addressed the demand side through offtake guarantees, the focus must now shift to regulatory and logistical facilitation. Implementing this scheme effectively requires coordination between multiple ministries, including the Ministry of New and Renewable Energy and the Ministry of Agriculture & Farmers' Welfare. The governance challenge lies in creating supportive local infrastructure, such as safe storage facilities to prevent fire hazards (especially during summer) and moisture damage (during monsoons). Furthermore, policies need to incentivize the aggregator model and facilitate farmer outreach, ensuring equitable participation and preventing monopolistic practices in feedstock procurement. The success of this initiative is crucial for achieving India's Panchamrit climate goals announced at COP26.
