Abstract
Abstract With the stabilization of Korea’s industrialization, it has become interested in the efficient use of rare met-als, climate change and industrial environment and safety etc. It is thus making efforts to implement economic policiesthat address such issues. Therefore it is necessary to understand the demand, supply and use of metal materials. Since2010, the Korean government has developed the integrated material flow methodology and has been trying to examinethe demand, supply and use of metal materials. In 2013, the Korean government surveyed the material flow of chro-mium. Material flow analysis and environment emission of chromium were investigated 8 steps; (1) raw material, (2)first process, (3) Intermediate product, (4) End product, (5) Use/accumulation, (6) Collection, (7) Recycling, (8) Dis-posal. Chromium was used for stainless steel, alloy steel, coated sheets, refractory material and coating materials. Recy-cling was done mainly in use of stainless steel scrap. To ensure efficient use of chromium, process improvement isrequired to reduce the scrap in the intermediate product stage. In the process of producing of the products using chro-mium, it was confirmed that chromium was exposed to the environment. It requires more attention and protectionagainst environment emission of chromium.Keywords: Chromium, Materials flow analysis, Environments emission, Recycle
