Due to economic feasibility and recycling policy of wastes, various types of residues have been studied particularly for high valued materials, such as gas adsorbents. In this study, the preparation of an adsorbent using the waste from coffee manufacturing process was attempted, and the removal efficiencies the odor and VOCs with acetaldehyde were quantitatively evaluated. The obtained coffee adsorbent had a specific surface area ranging from 400~1024 m2/g, the adsorption amount at the largest specific surface area was about 92.6 mg/g for acetaldehyde. The adsorption time by the characteristics of the adsorbents, such as pore, pore volume and the amount of adsorbent was also measured. This was to determine whether or not coffee adsorbents have any performance as adsorbent.
