In order to develop a method for reuse of waste paper, activated carbon was prepared from waste newspaper by a continuous method. Adsorption capacity of the activated carbon was measured. Pollutants such as heavy metals in leaching test solutions and in printing inks were determined. The adsorption capacity was almost 70% that of commercial activated carbon. Pollutants in the leaching test solution and the printing inks were found in low concentrations. On the basis of the results, it was concluded that the use of activated carbon caused little environmental impact.
