This paper is a research on the end-of-waste (EoW) criteria of steel scrap. Government strengthens the management of the scrap recently, as pollution has been raised due to the improperly treated steel scrap. In this study, current status of steel scrap recycling was investigated through field survey in 2012, and classification and recycling standard of steel scrap in developed countries and institutions were investigated through literature survey in order to introduce optimal EoW criteria. As a result, contents of contaminants were selected as the most important recycling standards, and contents of contaminants in steel scrap was measured less than 0.5% in most of companies, but only one recycling company showed 10% of contaminants. EoW criteria for steel scrap was determined to be below 2% of contaminants. In this study, contaminants in steel scrap was defined as hazardous and pre-treated substances, considering the Korean industrial standards (KS). And EoW stage was determined by considering the regulation on resources and practices in field.
