Captive Feedstock. Circular Agriculture. Zero Waste.
BNG Power's captive Napier grass cultivation model is one of its strongest competitive advantages — ensuring feedstock security, reducing input costs, and driving agricultural transformation in rural Rajasthan.
Feedstock Strategy
Dual Feedstock: Napier Grass + Organic Waste
Our CBG plant is designed around a dual feedstock model. The primary feedstock — approximately 90–95% by volume — is Napier grass grown on captive and contract farmland. The secondary feedstock is cow dung and organic waste sourced from local dairy farms and village collection points.
This dual-stream approach provides critical feedstock security: if one source faces disruption, the other maintains continuous plant operation. It also allows us to optimise the feedstock blend for maximum biogas yield and methane content.
Napier grass is particularly well-suited to Rajasthan — it is drought-tolerant, high-yielding, perennial (one planting sustains 5+ years of harvests), and thrives on the digestate we return to the soil as organic fertiliser.

Our Model
The Captive + Contract Farming Model
A two-track approach — direct captive cultivation for baseline feedstock security, supplemented by a structured contract farming network for scale.
Land Identification & Preparation
We identify low-fertility, underutilised land in the project area. The soil is tested and prepared with initial FOM application to improve baseline fertility before planting.
Napier Grass Planting
Certified Napier grass cuttings (stems/tillers) are planted in rows optimised for mechanised harvesting. First harvest occurs within 60–75 days.
Contract Farming Partners
For land outside our direct holdings, we engage local farmers through a structured contract farming model — providing planting material, agronomic support, and guaranteed buyback pricing.
Harvesting & Transport
Napier grass is harvested at optimal dry-matter content and transported to the plant. Mechanised harvesting equipment reduces labour costs and ensures consistent quality.
FOM/LFOM Return to Farm
Digestate from the CBG process is returned to the fields as FOM and LFOM — completing the circular loop. Soil health improves harvest after harvest.
Interested in Contract Farming?
Farmers, landowners, and cooperatives are welcome to partner with BNG Power under our structured contract farming programme.
FOM & LFOM: Closing the Circular Loop
Every tonne of feedstock that enters our digester produces not just CBG but also a valuable organic by-product: Fermented Organic Manure (FOM) and Liquid Fermented Organic Manure (LFOM).
These digestates are rich in nitrogen, phosphorous, potassium, and beneficial microorganisms. Applied to Napier fields and distributed to farmer partners, they dramatically improve soil health — reducing chemical fertiliser dependency and creating a true circular agricultural ecosystem.
Benefits of FOM/LFOM Application
- Increases soil organic carbon — long-term fertility improvement
- Boosts soil microbial activity and moisture retention
- Replaces 30–40% of chemical fertiliser requirements
- Improves crop quality — eligible for organic certification
- Reduces input costs for farmer partners by 20–30%
- Commercially sold to farmers beyond the contract network
