Corning Develops Emissions Filter

Corning Inc. said it has developed a catalytic converter filter to reduce auto emissions as much as 70% from current levels and that will help auto makers meet new pollution limits. The honeycombed filter is known as a substrate and will let auto makers avoid using bigger converters. It will go on sale this year for installation in model year 2000 vehicles; Corning would not disclose sales estimates for the filter. Auto makers must meet federal “Super Ultra-Low Emissions” standards in a majority of their passenger cars by 2004. Stock in the Corning, N.Y.-based company closed down 69 cents at $55.81 on the New York Stock Exchange.
