[Gasification] Biochar - Carbon Negative?

[Anand Karve]

Dear Mark,
with our system of charring, we get char yield of about 30% of the original
biomass. See our web site www.samuchit.com for a video of the process. But
what you say is basically correct. The sequestering of char is a carbon
negative process.
Yours
A.D.Karve
