Cork powder is the main residue of cork industry, being generated
throughout all the fabrication stages of cork products (milling,
sanding, cutting, etc.),of the cork powder generated worldwide.
This residue has been traditionally employed as combustion
fuel and to a lesser extent, as agricultural subtract or as a source of
chemicals [18]. Recently, cork powder has attracted attention as a
raw material for the preparation of activated carbons, where both
chemical [19–22] and physical [22] activation have conducted to
microporous materials with good adsorption performance in both
the liquid and the gas phases.
