India generates millions of tonnes of agricultural residue, cattle dung, food waste, and other organic biomass every year. While much of this valuable resource goes unused or is burned, Compressed Biogas (CBG) plants often struggle to find reliable feedstock suppliers.
To address this challenge, I built Biogas Exchange (HariPath), a multilingual digital platform that connects farmers, biomass suppliers, and CBG plants. The platform simplifies biomass trading through AI-powered logistics, digital contracts, subsidy support, and route optimization, making procurement faster, smarter, and more transparent.
The Problem
Biomass procurement remains one of the biggest operational challenges for CBG plants. Farmers often have limited access to buyers, while processing plants spend considerable time locating suppliers, negotiating prices, and organizing transportation.
Major challenges include:
- Limited connection between farmers and biomass buyers.
- High logistics and transportation costs.
- Poor visibility into available biomass resources.
- Manual procurement and contract management.
- Limited awareness of government subsidy schemes.
- Language barriers for rural communities.
Solution
Biogas Exchange creates a digital marketplace where farmers can list biomass, CBG plants can discover nearby suppliers, AI assists with route planning, and both parties can manage contracts and procurement from a single platform.
The platform focuses on improving transparency, reducing transportation costs, and encouraging sustainable utilization of agricultural waste.
Key Features
- Farmer Dashboard – Post biomass listings, manage contracts, track earnings, and monitor inventory.
- CBG Plant Portal – Discover suppliers, manage procurement, analyze logistics, and monitor operations.
- Interactive Biomass Marketplace – Browse nearby biomass listings with pricing, quality, and availability.
- AI Route Optimization – Generate optimized collection routes that reduce travel distance, fuel costs, and carbon emissions.
- Digital Contracts – Create procurement agreements directly from biomass listings.
- Government Subsidy Support – Explore schemes like GOBAR-DHAN, SATAT, PM-KUSUM, and National Mission on Biogas.
- Multilingual Interface – Supports English, Hindi, and Tamil for improved accessibility.
