The volatile gases released during charcoal production fuel the process itself, making it largely self-sustaining. The resulting charcoal is then used in a separate process to generate roughly a day's worth of electricity and hot water, forming a fairly carbon-neutral off-grid energy system. ## Full article daily.dev links to this article rather than hosting it.
