Alabama Dust Recycling plant proposed.Steel Dust Recycling LLC (Logical Link Control) See "LANs" under data link protocol. LLC - Logical Link Control (SDR See software defined radio. ), founded last year, has announced plans to build a Waelz Kiln kiln (kĭl, kĭln), furnace for firing pottery and enamels, for making brick, charcoal, lime, and cement, for roasting ores, and for drying various substances (e.g., lumber, chemicals). facility in Alabama that will be capable of recycling 110,000 tons of steel mill dust per year. The facility is slated to be built on 66 acres in Millport, Ala., close to the new SeverCorr steel mill. The decision to build the facility in Alabama comes after the company originally had planned to build the project in Mississippi. However, the company changed locations recently before completing the public hearings that were to take place. A preliminary report by the Alabama Department of Environmental Management has made a determination that the limitations and controls proposed by Steel Dust Recycling LLC will properly limit emissions. SDR is expected to recycle the steel mill dust generated at SeverCorr, as well as a number of other electric arc furnaces An electric arc furnace (EAF) is a furnace that heats charged material by means of an electric arc. Arc furnaces range in size from small units of approximately one ton capacity (used in foundries for producing cast iron products) up to about 400 ton units used for secondary in the Southeast. Russ Robinson, president of SDR, notes that more than 400,000 tons of steel mill dust generated in the U.S. is landfilled. "We're filling a need for an effective alternative to sending steel dust to landfills, and the Waelz Kiln is recognized as the best available recycling technology Recycling technology Methods for reducing solid waste by reusing discarded materials to make new products. The three integral phases of recycling are the collection of recyclable materials, manufacture or reprocessing of these materials into new products, and ." The technology is capable of recovering zinc from the dust, providing zinc-rich Waelz oxide to smelters. The remaining slag could then be used by cement producers or for road aggregate. |
