   Or what if the char is put in the ground for climate reasons?  Has huge value to some of us on that metric alone.

For example, if the feedstock is scrap/waste with no higher use, its value is close to zero.  Then the value of the Biochar can also be close zero as well.  The special case where the feedstock can NOT be used by a combustion device voids the  argument.

I expect Tom Miles has the cites for this.  What is the value/benefit of biochar used to enhance the success rate of reforestation?
