About
KohleHelden is a family-run biochar producer in Zierenberg (North Hesse, Germany) that uses a BIOMACON pyrolysis unit to convert regional wood chips into EBC- and GMP+-certified plant charcoal and feed charcoal. Their biochar carries certified CO2 sink performance that is marketed separately from the physical product, with buyers confirming non-combustion use. Sales run through their own webshop and Amazon.de.
