Interesting. It shows what you can do as an entrepreneur. They learned from an expert!

Funny enough - we once showed this company, Ecofuels Kenya, how to make wood vinegar (condensed smoke from the charcoal making process) and they have certainly taken it to the next level -  https://www.aiche.org/conferences/aiche-annual-meeting/2017/proceeding/paper/sustainable-approach-green-pesticide-production-kenya-croton-megalocarpus-trees as they now are the lead supplier of this stuff in East African horticulture industry and make hundreds of liters a month. 

 

They have shown that in certain cases, the smoke can be worth up to 15 times the price of the charcoal that it was made from. 

 

Best,

Michael I don't know the reason but Teddy's photos demonstrate lots of
room for improvement in the cooking.

I agree the big drawback in traditional charcoal making is waste and
pollution and making something from the "stranded" offgas is a worthy
goal but making syngas is a long way  from this.  Syngas (CO+H2) would
need to be made at much higher temperatures than are achieved in
traditional kilns  which is why the offgas is a cloudy sol containing
Products of Incomplete Combustion as well as tarry droplets condensed
from vapour, steam, water droplets. methane and longer chain organic
species.
