for your comments, our 10% biochar from a TLUD is reached because our main goal
of the cookstove is for cooking instead of biochar production. However, the
biochar could be used as an alternative solid biofuel, or for wastewater
treatment, or as a soil amendment.</span></p>

find enclosed to this email other analyses that we did on the gasification
biochar.</span></p>
