Rural Indian families traditionally cook on inefficient, wood-fired mud stoves which emit large amounts of health-harming smoke. Collecting firewood is also arduous – women often travel long distances on foot each day, spending further time cooking.

Sustainable Development Goals

3. Good Health and Well-Being

Improved household health

as clean-burning biogas will reduce the incidence of smoke-related illness

7. Affordable and Clean Energy

13,000+ Biogas systems

installed in Indian households, providing an affordable and clean fuel source for cooking

13. Climate Action

58,000 tonnes of CO2e

mitigated on average each year with this fuel sustainable fuel switch

15. Life on land

Less pressure on forests

as families cook with clean biogas instead of burning woody locally-sourced biomass

The Solution

This project involves installing biogas systems in rural Indian households to generate a sustainable energy source that can be used for cooking instead of firewood. These domestic biogas systems feature a fixed underground digester chamber made from locally available brick with an additional layer of cement mortar forming the roof. They are fed with manure, which is easily available for rural families who usually keep animals like goats. As the manure ferments, it releases methane, which is captured for cooking and heating water. The by-product, slurry, is used as an organic fertiliser for the families crops, making an efficient circular system.

The domestic biogas stoves come in a range of sizes to suit different family sizes and numbers of livestock.

The biodigester systems and easy to install and repair.

As many rural families have livestock, they have a free fuel source for the biodigester– animal dung!

The project is helping alleviate the burden of household tasks that fall on women.

The Impact

This project creates a range of community benefits that are transforming daily life, particularly for women who are no longer burdened with collecting firewood. As well as easing pressure on nearby forests, the project also cuts GHG emissions. Household and community health is improved too, the clean-burning biogas does not create indoor smoke, it reduces the risk of burns and provides a means to dispose of livestock waste, aiding rural sanitation.
