How to make biochar in large scale | (#6 How to build a house) 

Thanks for you coment 👍 BioChar and normal charcoal are produced by same procesy called pyrolisis. Pyrolisis is in simplified way “burning withou oxigen”. So both are made by same process. Main difference is that BioChar is produced during pyrolisis with higher temperature (450-650°C). Whole idea of “pit cone method” is to achieve burning withou oxygen on high temperature levels, both are achieved by pit shape and pileing red hot char in one spot. BTW I was burning it for 10 hours so temperature was extreme so BioChar is born 👍😁
