Ā @GraniteInTheFaceĀ making coconut š„„ shells to charcoal has probably been done for a 1000 years, it's about finding the best method. I read that In Indonesia, Yayasan Dian Tama, a small community development group based at Pontianak, West Kalimantan, has developed a simple technology for producing coconut-shell charcoal. The technique involves the use of a 200-litre drum as a kiln, and is claimed to be the most effective way of manufacturing coconut-shell charcoal. In weight terms, the efficiency of conversion has been reported to be as high as 25%, which is twice as high as that achieved by traditional methods. Moreover, the production-time per batch is only about 20 hours, which is very quick.
Preparing the drum - (Figure 1)
1. Make a hole with a diameter of 30cm in the middle of the top part of the drum. The small round plate removed is to be used as a cover.
2. Make small holes at the bottom part of the drum to allow the air to enter.
3. Fix a wooden or bamboo handle onto the round plate so that it will not fall in when used as a cover.
The process - (Figure 2)
a) Put some stones under the drum (in order to let in the air), and fill one third of the drum with coconut shells.
b) Put in a little kerosene - just enough to allow the shells to catch fire, and keep the fire burning for five minutes (you will see black smoke coming out of the drum).
c) After five minutes, put the lid on the drum to put out the fire, and wait until white smoke comes out of the drum.
d) Open the lid and let the smoke out.
e) Add more coconut shell to the drum - as much as 10kg - and wait until more black smoke is emitted, which means the coconut shell is burning. Continue to do this until the drum is filled with charcoal.
