AT&T WINS AWARD FOR WORK IN HELPING PROTECT STRATOSPHEREIC OZONE LAYER

AT&T WINS AWARD FOR WORK IN HELPING PROTECT STRATOSPHEREIC OZONE LAYER
 BASKING RIDGE, N.J., Sept. 30 /PRNewswire/ -- AT&T has won an award from the U.S. Environmental Protection Agency (EPA) for developing technologies that reduce the use of chlorofluorocarbons (CFCs) during manufacturing. CFCs are blamed for damaging the stratospheric ozone layer.
 The 1992 EPA Stratospheric Ozone Protection Awards were presented last night at the 1992 International CFC and Halon Alternatives Conference in Washington, D.C. AT&T was among 10 corporations that received the award. The company won for its global elimination of CFCs. To date, AT&T has reduced its CFC emissions by 76 percent. The company's goal is to eliminate those emissions by year-end 1994.
 Depletion of the ozone layer -- which allows excess ultraviolet radiation to reach Earth -- has been linked with increased skin cancer, cataracts and immune deficiencies in humans. It also affects the growth of phytoplankton, which is at the base of the marine food chain.
 "Our CFC alternative technologies go beyond traditional approaches, such as substituting one ozone depleter for a less harmful depleter, and instead introduce technologies that eliminate the use of CFCs in certain manufacturing processes," said David R. Chittick, environment and safety engineering vice president, AT&T. "These technologies are being used in manufacturing operations around the world."
 "This year's awards honor technical and managerial excellence," said Stephen Andersen, director of Technology Transfer, Global Change Division, EPA.
 Since there is no single replacement for CFCs, AT&T Bell Laboratories scientists developed an array of alternatives, including:
 -- Water-soluble flux, which makes it possible to clean certain types of circuit boards with water instead of with CFCs.
 -- BIOACT-EC7, an orange-rind-based, biodegradable cleaning solution for circuit boards that cannot be cleaned with water alone. The solvent can be safely handled by a conventional sanitary waste treatment facility.
 -- Low-Solids Fluxer, which eliminates the need to clean electronic circuitary after soldering. This technology produces high quality products, while lowering costs by reducing manufacturing steps and conserving materials.
 AT&T's environmental program also includes goals to cut toxic air emissions and manufacturing waste, increase paper recycling, and reduce paper use.
