Cow dung, kitchen scraps, and other organic waste are mixed with water to form a slurry.

The slurry is fed into an airtight digester, where microbes break it down in the absence of oxygen.

This process releases methane-rich biogas, which is collected and piped to households for cooking or lighting.

Turning Everyday Waste into Sustainable Energy for Villages

now access clean biogas for daily cooking

Green Solutions, based in Nainital, Uttarakhand under the leadership of Nityanand Joshi, is pioneering impactful household biogas initiatives across the region. With a strong environmental engineering backbone, they specialize in crafting and deploying smart, clean, and locally adapted biogas systems that empower rural households—delivering low-carbon cooking fuel, reducing deforestation pressures, and fostering energy self-reliance in the Himalayan communities.

Safeguards habitats and native species

Generates local jobs and income

Improves public health through cleaner air and water

Strengthens ecosystems against extreme weather

This project installs over 13,500 household biodigesters across rural Uttarakhand, replacing traditional wood-fired stoves with clean, renewable biogas systems. Powered by cow dung, these Deenbandhu-model digesters provide a sustainable cooking fuel, reduce greenhouse gas emissions, and curb deforestation. They also improve rural hygiene through proper waste management, while producing nutrient-rich organic fertilizer that enhances soil health and agricultural productivity. 

Certified under the Verified Carbon Standard (VCS), the project delivers measurable climate benefits alongside improved livelihoods and energy access.
