Making Charcoal from Corn Cobs
April 15, 2008 by Leo 4,317 Views
Fumes from indoor cooking fires are responsible for more than 2 million deaths every year in the developing world. But by simply turning their farm waste into a cleaner burning fuel it may be quite simple to make that dire statistic a thing of the past.
Materials needed:
- Corn cobs
- Drum, 200-lit. capacity
- Sprinkler
Procedure:
1. Place the corn cobs inside the drum about 1/3 in height and burn until the smoke disappears.
2. Fill the drum additional corn cobs (about 2/3 in height) and burn again until smoke disappears.
3. When the smoke ceases, empty the drum.
4. Sprinkle water into the burnt corn cobs.
5. Spread the cobs for drying under the sun.
6. Separate the charcoal from the ashes.
7. Store.

I know some people living in a rural village in Zambia who say they made charcoal from corn cobs but it did not burn hot enough to cook with.
Anyone have any experience with this?

this is a good idea but in my industry we can already use corn cob as substitute. can you gave me idea where to get volume of corn cob at low price? thanks..
@FelixJr, your best source can be at the corn plantation itself, if you pass-by at the south luzon area (cavite, batangas, quezon), there are several plantations there.
