Corning Inc. recently celebrated the opening of its new clean-air products plant in Erwin, N.Y. New York. Governor George Pataki helped lead the grand opening of the $200 million production facility. Production of large Corning diesel substrates began at the plant in January 2004. By January 2005, the manufacturing facility is expected to employ approximately 250 people. New emission requirements for the diesel vehicle market are estimated to create an approximately $1 billion worldwide market for substrates and filters by 2008. The new facility will help meet this growing global demand, as it is designed and built to meet the specific large-scale manufacturing operations required to produce substrates and filters for medium- and heavy-duty diesel applications, such as trucks and buses. Corning invented an economical, high-performance cellular ceramic substrate in the early 1970s that is now the standard for catalytic converters worldwide. In 1978, Corning developed the cellular ceramic particulate filter to remove soot from diesel emissions.
