EAF Dust Recycling

AZR’s state-of-the-art recycling facilities recover zinc from EAF dust generated by mini-mill steel producers a listed hazardous waste under EPA regulations. AZR's management of this material is in accordance with Environmental Protection Agency requirements and allows the steel producers an option over landfilling or other expensive disposal methods.

AZR utilizes high-temperature rotary (“Waelz”) kilns to reduce and volatilize zinc from EAF dust and recover it, along with other volatile impurities, as a crude oxide (“Waelz Oxide”) baghouse product. The WOX is further refined to zinc metal at AZR Metal Products’ facility in Mooresboro, NC. AZR operates nine Waelz kilns at four strategic locations, Chicago, IL, Rockwood, TN, Palmerton, PA and Barnwell, SC.
