I spoke with a purveyor of biochar furnaces a few years ago.  He claimed 
that the process he used was a high temperature burn, and the burning 
was remarkably clean.  I have no confirmation of that but he certainly 
wasn't using a charcoal mound.

I remain hopefull that biochar could well be the saving of the 
rainforests.  A simple change from slash and burn agriculture to slash 
and char could be HUGE.

Thank you kindly,

Corwyn
