The U.S. Environmental Protection Agency's Superfund Innovative Technology Evaluation (SITE) program selected the Horsehead Resource Development Company, Inc. (HRD) Flame Reactor technology for evaluation by demonstration which took place in March 1991. A series of test runs was conducted at the HRD facility in Monaca, Pennsylvania, using 72 tons of secondary lead smelter slag (SLSS) from a Superfund site in Atlanta, Georgia. The SLSS contained zinc, iron, cadmium, and many other metals and inorganic compounds. The HRD Flame Reactor technology is a patented high-temperature thermal process designed to safely treat wastes containing metals. During processing, the waste is introduced to the hottest portion of the HRD Flame Reactor, where it is subjected to greater than 2000 C reducing gas. The waste material reacts rapidly, producing a nonhazardous vitrified effluent slag and gases, including steam and metal vapors. The metal vapors react in the combustion chamber to produce the metal-enriched oxides that are collected in a baghouse. The SITE program evaluated the HRD Flame Reactor for its effectiveness in treating a Superfund site waste, which is hazardous (by Toxicity Characteristic) for cadmium and lead, to form a recyclable metal oxide and a vitrified slag that is nonleachable.
