The steel-making industry produces a large amount of Electric Arc Furnace (EAF) dust as part of normal production. This waste is listed as KO61, defined as {open_quotes}emission control dust/sludge from the primary production of steel in electric arc furnaces{close_quotes} under 40 CFR 261.32. A glass making technology called Ek Glassification{trademark} (hereafter called {open_quotes}the Process{close_quotes}) has been developed by Roger B. Ek and Associates, Inc. (hereafter called {open_quotes}the Developer{close_quotes}) to recycle EAF dust and convert it, along with other byproducts of the steel-making industry, into marketable commodities. This Process was evaluated under the Waste Reduction Innovative Technology Evaluation (WRITE) Program. The project was designed and conducted in cooperation with the Washington State Department of Environmental Quality, the Process Developer and the host test site, the Earle M. Jorgensen (EMJ) Steel Company of Seattle, Washington. Test personnel for EPA were supplied by SAIC Inc., on contract to EPA. The overall objectives of the project were to conduct a pilot scale evaluation of the Process, investigate if toxic metals are leached from the products (such as colored glass and glass-ceramics; ceramic glazes, colorants, and fillers; roofing granules and sand-blasting grit; and materials for Portland cement production). Three glass recipes (Glass I, II, and III) were designed by the developer for potential use at EMJ. The EPA portion was focused on determining the toxic metals concentrations of the Glass II recipe, evaluating the P2 impact of using this Process in comparison to traditional methods of waste treatment and disposal, and assessing the economics of both.
