The company recently said it plans to 2008. The use of scrap only from the current 60,000 t / a to 2008 of 100 million t / a at present, the company's steel scrap is mainly used for Keihin and Fukuyama Works plant, future plans, and Kurashiki plant in Chiba The two plants are also used as scrap. Scrap use of the company's main factors: a scrap and other raw materials prices; the second is the level of steel production and carbon dioxide emission levels. From the current situation,[link widoczny dla zalogowanych], the use of scrap materials for lower costs and reduce carbon dioxide emissions is very good, is a long-term viability of the method. Currently, JFE steel scrap used depends mainly on internally, but in the future with increased use will also go to the market to buy. In the next two to three years,[link widoczny dla zalogowanych], will make a final decision on this issue. Du Feng translated SteelWeek2005 message on November 18
