For Achievement of Sustainable Society

Non-ferrous smelting industry is necessary for supplying materials to high-tech industries and in order to achieve the resource circulation society.
In the future, the use of various electrical and electronic devices such as PC and electric vehicles is expected to increase with growth of population in the world.
To secure metal resources continuously, it is necessary to recycle metals used in waste products.
The main research aim is to establish the metal resources circulation system based on the non-ferrous smelting technologies with proposing the metal resources circulation engineering as an academic innovation.
Developments of new process technologies and problem-solving researches for such as smelting technologies for secondary resources and stabilization of environmental load elements will be conducted in order to achieve the metal resources circulation system.
