Abstract

For making a study on control of cadmium, life cycle flow in Japan and relation with other countries about NiCd batteries including cadmium were analyzed. As a result, it was appeared that within the country, the collection and recycling systems of NiCd batteries did not function and the amount of exported cadmium as metal is increasing while the amount of production is decreasing. Additionally, it was indicated that mineral ore such as zinc ore including cadmium, cadmium itself and productions including cadmium were dynamically distributed in Pacific rim. It was concluded that the discussion about control of cadmium on a global scale was necessary.
