Abstract

The origins and characters of steel scrap were quantitatively estimated by using officially published statistic data combined with unpublished data which were available only within individual industries. The estimation procedures include (1) tabulating the amounts of steel products in the past 45 years, (2) classifying steel scrap into individual origins, and then (3) revealing the characters of the scrap. As results, the origins of the scrap generated in 2000 were made clear based on the whole material flow ; for example, 75% in the total amount of steel scrap was produced by basic oxygen converter in the past and 45% of the obsolete scrap was generated from cold-rolled coil.
