The total crude steel production in Asian countries was 500 million t in 2004, which accounted for 47% of the total crude steel production in the world. There have been a large demand of steel scraps in Asian countries, which Japan exported 2.5 million t of steel scrap to China, 1.91 million t to Korea and 0.9 million t to Taiwan in 2003. According to our previous studies, steel scrap generation in Japan will increase until 2030. Change in steel scrap demand in Asian countries in the future will make a great influence on the amount and quality of Japan's steel scrap domestic consumption and export. In this work, estimated was the quality change in domestic steel production (Electric Arc Furnace steel for buildings & constructions) by steel scrap exports. The method based on population balance model and material pinch analysis was applied to assess the quality of domestic steel production and steel scrap consumption. The data concerning the quality (copper content) of steel scraps and recovery ratio of steel scrap from post consumer products were updated. It was found that quality requirements on steel scraps to other countries could have large influence on the quality of domestic steel.
