Steel Dust Recycling (SDR) announced plans to build a Waelz Kiln facility in northwestern Alabama to recycle 110,000 tons per year of EAF dust. The facility will be built on 66 acres in Millport, Ala., near the SeverCorr steel mill currently under construction in Lowndes County, Miss. SDR will recycle SeverCorr’s steel mill dust as well as dust from other EAF plants in the southern United States.
Waelz Kiln technology will recover zinc from the dust. The zinc-rich Waelz oxide can then be provided to smelters in North America or elsewhere, and the remaining steel-based slag can be used by cement producers or for road aggregate.
