Processing of Coconut Shell into Activated Carbon/Charcoal
Coconut shell, a byproduct of copra processing, is a good material for activated carbon/charcoal (Fig. 1). 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.
