[Stoves] ***SPAM*** Methane emissions during pyrolysis / charcoal production

[Christa Roth (bioenergylist)]

Dear colleagues

Anybody know any figures on methane emissions while making biochar or producing charcoal? 

I recently got alerted about unexpected amounts of methane emitted from gasifier cookstoves when making char. 

Does that also occur when making biochar or normal charcoal? I guess a retort will be a good option to burn up any potential methane?

During ETHOS quite a bit about the real -life figures about charcoal production were discussed but I am not aware of any methane figures. 

Any leads?

Well done. But I cannot open the link. 
Are they selling the briquettes for about the same price as charcoal? Are they seeking carbon credits?

Dear All,
I purposely did not fly from Nairobi to Kisumu (Lake Victoria) but i took a bus (9hrs) to see the landscape in Western Kenya. I was expecting dry land as the newspapers report about the draught and kettle dying in Kenya.
But to my surprise whole of the 9hrs of traveling we passed green and fertile landscape, old and young trees everywhere, some tree newly planted in groups or plantations, some trees very old and large.
In Kisumu/ Kakamega i visited the project of

Which is carbonizing sugar bagasse and daily briquetting the char to be used as cooking fuel.
I was building a Shelter Drum Retort Kiln there, which i developed,  for testing purposes.
