Feedstock sourcing: The next critical lever for scaling CBG ecosystem
Industry experts emphasize that establishing a robust supply chain for feedstock is essential for the scalability of the Compressed Biogas (CBG) ecosystem in India. The government's GOBARdhan scheme aims to increase production tenfold, but logistical challenges regarding feedstock storage and transport remain.
Why it matters
Scaling biogas production is a key component of India's renewable energy strategy and waste management goals.
While the Union Government’s latest push for Compressed Biogas (CBG) provides a more stable framework for offtake, industry observers and senior government officials say the next major imperative is to establish an efficient supply chain for procuring, storing and managing feedstock. This will be critical to ensuring both the viability of CBG plants and the quality of their output.
Press mud, agricultural residues such as paddy and wheat straw, and animal manure are among the most commonly used feedstocks for CBG production. However, each has its own logistical challenges, particularly because of seasonal availability, transportation requirements and storage constraints.
With the aim of accelerating the growth of CBG in India, the Union Cabinet on August 9 approved a revamped GOBARdhan (Galvanising Organic Bio-Agro Resources Dhan) scheme with an outlay of ₹23,731 crore. The scheme, which will remain in place until 2036, seeks to increase CBG production nearly tenfold.
