Jiko Tosha

Why to choose this solution?
The multi-purpose fuel cooking stove (Jiko Tosha) is an improvement on the currently available rocket stoves that use a single type of fuel, either firewood or charcoal. Jiko Tosha stove accommodates the use of several fuel forms, animal wastes, firewood, charcoal/briquettes, sawdust, biogas, and LPG. Any of these will work in the same stove unit. The Jiko Tosha stove was born out of shortcomings identified in the stoves existing in the market. Its advantages are that it reduces indoor emissions, provides a safe and healthy environment to the consumer, accommodates more than one fuel source according to availability, and ensures that the users have access to economical and affordable cooking technology.
Savings per day or production:
Savings of about 70% of charcoal consumption per day for a normal family.
