Design and development of domestic and community improved biomass cook stoves
starting from small family of 5 to 200 community size

Advantages / Salient Technical Features
• An improved biomass cookstoves which can burn fuel
efficiently with reduced harmful emissions
• Health-related benefits of the use of improved
cookstove (ICS) - reduced smoke , fuel efficiency,
and saves time, together with flexibility in the size of
cooking pans, ease of use, appearance and safety.

Problem being addressed
• In India about four hundred million rural inhabitants
is facing a severe energy crunch. The energy shortage
is most acute among India’s rural poor, the majority
of whom rely on relatively inefficient, polluting and Application/Uses
