Stein is able to reclaim scrap that is high in metallic content We accomplish this through the use of scrap slag separator plants which are custom designed to satisfy the requirements of each steel operation we service The reclaimed metallic scrap is returned to the steel making and iron making facilities or sold externally by Stein

Iron and Steel Slag Exemptions from the Definition of Solid Waste The attached document “Iron and Steel Slag Exemptions from the Definition of Solid Waste” was developed to provide guidance regarding the conditional exemptions of iron and steel slag from regulation as a solid waste under 2017 Wisconsin Act 285

The high content of CaO in the slag can be used to substitute for a part of limestone as fluxing material to reduce the iron in steel making cost Many steel plants of the World utilize LD slag as the replacement of limestone Steel slags contain higher amount of PS which seriously affects the direct recycling to iron and steel making process
