Smokeless bamboo charcoal making

With the help of my good friend Ray Eshelby we built a smokeless charcoal retort from up-cycled materials and it works perfectly – we use wood from the garden as fuel in the outer chamber and pack the inner chamber with bamboo pieces, light it from the top and then put the lid with the chimney on top.

The wood gases are being burnt off inside for extra efficiency and only a heat flare is visible, there is no smoke whatsoever after closing it. It burns for a few hours and the huge amount of heat can also be used, for example for cooking, frying or boiling water for purification.

I am hugely excited about this success, since bamboo charcoal has superior qualities and a wide range of practical applications such as soil enhancement, filters, and fuel, just to name a few.
