Activated carbon is amorphous and its intraparticle pores are well developed. Thus it has high adsorption capabilities and catalytic effect, and is utilized in many areas of industries such as food processing. In recent years, the demand of activated carbon has been increased to solve the environmental problems-waste treatment and removal of poisonous gas. Therefore, in this study an activated carbon was made using the waste and then the industrial characteristics of the produced activated carbon were investigated. The result showed that the carbonization yield was decreased when carbonization temperature was increased from 400 to and that the optimal carbonization temperature was . The optimal concentration of NaOH for removing ash in the raw sample was 1~2N. The iodine adsorption of activated carbon using waste sample at carbonization was 1204.28mg/g. The activation result of carbonization sample showed that the optimal activation condition was the carbonization at and the activation at . So the production of activated carbon was thought to be possible, reused as resource, and decreased the environmental pollution.
