In 1991, an unusual aluminum recycling dry process for beverage cans was developed, which enables that the more than 83 per cent of metallic aluminum can be retrieved from scrap cans within the quality of Japanese industry standard (JIS3004). However, in this process only the base paint powder is remained as waste after the pelletizing. We studied the characteristics of this base paint powder and investigated the possibility of utilization as a photo catalyst because of much contents of TiO2 in the powder.
