Description:
This document is an evaluation of the Ek Glassification Process to recycle and convert K061-tested waste (Electric Arc Furnace) and other by products of the steel-making industry into usable products. he process holds potential for replacing the need for expensive disposal costs associated with the listed waste with the generation of marketable products. he products include colored glass and glass-ceramics; ceramic glazes, colorants, and filters; roofing granules and sandblasting grit; and materials for Portland cement production. ield 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. CLP testing of the product determined that leachability characteristics of metals in the product meet treatment standards for K061-listed waste. he 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. lthough 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.
