EarthSaathi is a youth-led climate technology startup in India developing low-energy carbon capture and utilization solutions for biogas plants and decentralized energy systems. Operating for 1-3 years and currently in the testing and prototyping stage, the project focuses on improving biogas quality by removing carbon dioxide, increasing methane purity, and enhancing the efficiency of renewable energy systems.

The innovation uses an energy-efficient solvent-based carbon capture process to extract CO₂ from biogas streams. Rather than releasing the captured carbon into the atmosphere, EarthSaathi converts it into eco-construction materials such as eco-bricks through mineralization, creating a circular system that combines renewable energy production, carbon reduction, and long-term carbon storage. The technology is designed to be affordable, modular, and suitable for distributed energy systems in developing countries.

Impact: Supports clean energy access, emission reduction, carbon management, sustainable construction, and circular economy development. The initiative contributes to SDGs 7, 9, 11, 12, and 13.

Revenue Model: User fees, sales to private organizations, sales to government agencies, technology licensing, deployment partnerships, and carbon utilization products.

Expenses: Research and development, laboratory testing, pilot system fabrication, field deployment, equipment procurement, solvent development, operational costs, and technical staffing.

Challenges: Scaling technology from laboratory validation to commercial deployment, increasing awareness of carbon capture solutions in decentralized energy systems, securing funding for pilot projects, and demonstrating long-term technical and economic viability.

Vision: To establish a network of decentralized carbon capture systems integrated with biogas plants and small industrial emitters, transforming waste CO₂ into valuable construction materials while improving clean cooking fuel access, reducing emissions, and supporting circular economy development across developing countries.

Development Stage: Testing and Prototyping.
