摘要

This document is an evaluation of the Ek Glassification(TM) Process to recycleand convert K061-listed waste (Electric Arc Furnace or EAF dust) and other byproducts of the steel-making industry into usable products. The Process holds potential for replacing the need for expensive disposal costs associated with the listed waste with the generation of marketable products. The products include colored glass and glass-ceramics; ceramic glazes, colorants, and fillers; roofing granules and sandblasting grit; and materials for Portland cement production. Field testing of the technology was conducted by the U.S. Environmental Protection Agency (U.S. EPA) in early July of 1991 at the Earle M. Jorgensen Steel Co. (EMJ) plant in Seattle, Washington, and both technical and economic aspects of the technology were examined. TCLP testing of the product determined that leachability characteristics of metals in the product meet treatment standards for K061-listed waste. The Process was also shown to be economically viable, based on capital and operating cost estimates, and profit and revenue forecasts for a 21,000 ton-per-year operation. Although this effort showed that the technology holds promise, regulatory compliance should be evaluated on the basis of the actual hardware configuration and operating procedures along with the leachability of the specific product formulations to be used.
