 BETHPAGE, N.Y., Oct. 25 /PRNewswire/ -- Grumman Corporation (NYSE: GQ) announced today a 64 percent reduction in its hazardous waste.
 In the Toxics Release Inventory report (TRI) recently submitted to the Environmental Protection Agency, Grumman reported a reduction of over 2.4 million pounds of hazardous waste since 1988.
 Grumman has always worked with customers, suppliers, and with federal, state, and local authorities to use all manufacturing substances safely and dispose of them properly. However, the focus of these efforts has changed.
 "It's a change in philosophy from managing waste to eliminating it in the first place," said Art Gibson, director, environmental affairs and occupational safety and health. "The company is working very hard to make up-front changes in manufacturing processes and to identify chemical substitutions."
 Grumman is one of the charter companies participating in the EPA's Voluntary Industrial Toxics Project. This program is designed to reduce hazardous waste by cutting in half the use of 17 selected chemicals by 1995. Grumman uses nine of the substances and has already reported a 60 percent reduction.
 The company also reported a 73 percent reduction in emissions of ozone depleting substances. Using water soluble coolants and lubricants in manufacturing has significantly contributed to the reduction of chlorofluorocarbon emissions, which have been reduced by 92 percent.
 By 1994, Grumman will have replaced 90 percent of its trichloroethylene vapor degreasing tanks, used in aircraft manufacturing, with water and alkaline-based cleaning solutions. The company has also identified water-based and citrus-blend products as alternatives to certain cleaning solvents. Trichloroethane has already been replaced with a citrus-blend cleaner for use on the paint conveyer belt at the facility where Grumman builds the mail delivery truck for the U.S. Postal Service.
 New emission control equipment recycles 90 percent of perchloroethylene, a chemical used to prepare metal surfaces for etching. As an alternative to methylene chloride, a solvent for stripping paint, the company is using "plastic media blasting." In this process, plastic beads are blasted against a surface, stripping paint without harming the surface. Other potential alternatives include using wheat starch or an environmentally acceptable chemical stripper.
 Grumman expects to achieve significant future reductions in chrome emissions by the first quarter of 1994. Further decreases in trichloroethane are also expected as Grumman phases in new water-based primer and high solid paint products.
 Grumman Corporation is best known as a leading international aircraft and aerospace company. Other businesses range from sophisticated integrated information and electronics systems to aluminum walk-in vans. Headquartered in Bethpage, Grumman employs 19,000 people. Revenues were $3.5 billion in 1992.
