05. Biochar producing cook stoves

Examples of these stoves include the Top-Lit Updraft Gasifier (TLUD) (IBI 2009), Anlia Stove (IBI 2009), the Mafiga stove (PISCES 2009), and the Sampada stove (ARTI 2009). These are technologies appropriate for deployment in rural India, for example the TLUD has two types, the ‘refugee’ made of tin cans and the ‘artisan’ version which will be manufactured in India (IBI 2009). The Anila stove has been investigated to determine the impact of the biochar it produces on agriculture with encouraging results since the biochar was found to be of a consistent nature in terms of pH and conductivity. The yield of biochar was enough for a yearly application rate of 0.5t/ha which would be ideal for users with small areas of land – typically the poorest farmers (Iliffe 2009). The Appropriate Rural Technology Institute (ARTI) are currently promoting the Sampada gasifier stove which leads to negligible emissions after the first ten minutes, operates for about 30-40 minutes per batch of 1 to 1.5 kg fuel (depending on fuel type), and produces about 200-300 gm of charcoal as a bi-product, which can be used as biochar.

    We are also working on biochar as a byproduct of bio-oil production from a variety of biowastes including weeds and their soil application for numerous agronomic benefits as soil conditioner. C-sequestration and reduction of emission of GHGs through biochar application to soil are other aspects of this study.
