BIOCHAR PIT KILN is one of the simplest method of converting the crop residue and other biomass into Biochar / charcoal The farmers can easily create pits / trenches and convert the biomass residue (apart from using for compost, mulch, etc) otherwise wasted by burning in the fields openly. The tribals at Yerragondapalem (supported by NABARD / Sri Sai Educational Society), in Andhra Pradesh were trained in this method (GSBC Project), they are able to produce the biochar, preparing biochar compost and applying to their fields.

* About 30% biochar production
* 3 to 4 days for a batch of charcoal production
* Continuous hot water access (pot 1)
* Highly suitable for institutional cooking and as well making biochar
* Additional heat generated by flaring the pyrolysis gases, used for cooking
* Mitigation of the emissions during the pyrolysis by flaring
* Costs about Rs. 3000 for a 2’ width x 5’ depth x 6’ hight (in feet) “GEO Biochar pit stove”. (cost including, tin sheet for cover, digging the pit, three pot stove and chimney.)
*_"GEO BIOCHAR STOVE" is designed by Dr. N. Sai Bhaskar Reddy, CEO, GEO. Demonstrated to farmers under the project Good Stoves and Biochar Communities Project, being supported by, France
