Waste plastics are defined as one of organic wastes. According to an official report, the annual total discharge of the waste plastics in Japan shows more than 5 million tons in 2002. Organic waste utilization technology should be developed to decrease of waste plastics, because the landfill cannot be accepted for the industrial waste any more. In order to obtain porous carbonized materials from waste plastics, waste phenol resin was selected to suitable for making carbonized materials.The purpose of this study is to develop the activated carbon from waste phenol resin and reuse it for functional carbon resources.The structure of carbonized waste phenol resin was analyzed with gas adsorption measuring apparatus. The results show that the specific surface area of carbonized materials showed more than 900m2/g, when they were carbonized at the lower temperature of 600°C for 10 minutes in N2 and activated at 1000°C for 120 minutes in CO2.Moreover, activated reaction for waste phenol resin were investigated at the carbonization temperature of 800°C for 60 minutes in N2 and activation temperature of 1000°C in CO2 by using Ca(OH)2 as catalyst. The specific surface area of carbonized materials mixed with Ca(OH)2 after activated at 1000°c for 10 minutes showed about 500m2/g. This value was corresponded to nearly five times of non catalysts at same condition. Therefore, it was confirmed that the Ca(OH)2 could be advanced the activated reaction for carbonized waste phenol resin.
