Recycling offers a means by which hazardous materials can be kept from entering the environment. In addition to its environmental benefits, the recycling of certain byproducts, sludges, and spent materials generated from industrial processes was viewed by some as a means for exclusion from regulation under RCRA. Under EPA's 19 May 1980 regulations, non-listed wastes that were recycled were not regulated. Consequently, many activities called recycling occurred but were viewed by EPA as analogous to land disposal or incineration rather than recycling. Ultimately, these issues served as an impetus to reconsider the recycling provisions of the RCRA regulations; in particular, EPA undertook an extensive rewrite of the definition of solid waste. This paper explores a case of a proposed modernization to USS-POSCO's steel finishing plant in Pittsburg, California, and how it has been affected by EPA's definition of solid waste. The modernization would include a closed-loop facility in which the spent pickle liquor would be processed, resulting in hydrochloric acid that would be reused in the pickling lines. The ferric oxide produced through this process would be removed and sold.
