How to make Activated Carbon


Activated Carbon from coconut shells, a by-product of copra processing, is a good material for activated carbon/charcoal production. Activated charcoal (charcoal activated with CO2, water vapor, or chemical compounds) made of coconut shell has advantages compared to other materials (wood, rice husk, corn cob) because of its ability to absorb color or aroma. It is used as supporting material for food and non-food industries (processing of cooking oil, sugar, and chemical matter purification). Generally, coconut production at farmer level is 1 ton/ha, with coconut shell by-products of 0.9 ton, which in turn can yield 0.36 ton of activated charcoal. Price of activated charcoal is US$440.00/ton.


Processing of activated charcoal

Materials and equipment:

Coconut shell
Drum or burning sink

e. Wash charcoal with distilled/clean water.
f. Spread on tray at room temperature to be drained.
g. Dry in oven at temperature 110 oC for 3 hours.

  9. Victor, you can search buyers on the internet. You post FOB prices per ton and other information such as moisture and grades (mesh size).

  10. Maria, you can buy the mesh from hardwares that see fish net or screen wires, just tell them you need a 100 mesh size. You can then make a sieve out of it.
