Biochar is a carbon-rich byproduct of low-temperature incineration of biomass and is used to condition soil. Once the harvesting season is over the rural farmers take a little of the biomass to feed the cattle and the rest of it is burned in the fields.
This not only pollutes the air but increases the release of carbon dioxide into the atmosphere. SCAD introduced a simple but reliable device called an ANILA stove which produces biochar from the biomass. The stoves can be used to help people cook and also can provide an income by selling the bio char produced during the cooking period.
The bio char can then be mixed with cow dung and other natural manure and applied to the soil as a soil natural fertilizer.
