We believe that we are one of the leading environmental service providers to the U.S. steel industry, having recycled 12.1 million tons of EAF dust since 1990, which is the equivalent of approximately 2.5 million tons of zinc to date representing the dust generated in the production of over 620 million tons of steel. Our recycling and conversion of this EAF dust reduces a steel mini-mill's exposure to environmental liabilities which may arise when the EAF dust is sent to a landfill. Our predecessor company developed this proprietary process during the 1980s and have been a leading EAF dust processor ever since. We use the recycled material as low cost feedstock for our metal production operations, yielding a competitive cost advantage.
