Product Description

The husk and shells can be used for fuel and are a source of charcoal. Activated carbon manufactured from coconut shell is considered[by whom?] superior to those obtained from other sources, mainly because of small macropores structure which renders it more effective[weasel words] for the absorption of gas and vapor and for the removal of color, oxidants, impurities and odor of compounds.
