PPG WASTE REDUCED 49,000 TONS IN 1991

 PPG WASTE REDUCED 49,000 TONS IN 1991
 PITTSBURGH, June 23 /PRNewswire/ -- PPG Industries (NYSE: PPG)


today reported that its North American facilities generated 49,000 fewer tons of waste -- trash to process residues -- last year than in 1990.
 "The 15 percent waste volume reduction is substantial," said Paul M. King, corporate director of environment, health and safety. "However, an 8 percent lower rate of waste per ton of product fell short of our 11 percent goal."
 Of the volume decrease, 6,300 tons -- about 13 percent -- was in hazardous wastes.
 "We're aiming for a greater overall rate reduction of 12 percent in 1992," King said.
 He noted that through 1991, the company has lowered total wastes 29 percent, or 110,000 tons, and hazardous wastes 17 percent, or 23,000 tons, since initiating a formal North American accounting system in 1988.
 In addition to total volume, PPG measures waste minimization progress by rate of wastes generated per ton of product for meaningful comparison regardless of variable production levels, according to King.
 "Although technology remains a barrier to zero waste and makes annual improvement increasingly difficult, we strive to advance technology and our people work hard to improve processes and find new or better ways to minimize waste," he said.
 "Waste reduction has many benefits -- for the environment, energy conservation, the cost of doing business, productivity and competitiveness."
 As an example of continuing improvement efforts, he noted that PPG's Cleveland automotive coatings plant recently completed a recycling facility, financed in part with a federal Department of Energy and Environmental Protection Agency grant, designed to reduce a major production unit's annual water consumption from 400,000 gallons to 20,000 gallons.
 PPG's Glass Group reduced wastes in 1991 compared with 1990 by about 32,000 tons, for 19 percent volume and 9 percent waste per production rate improvements. However, its hazardous wastes increased about 7,000 tons -- three times those of 1990 -- in large part because revised EPA tests reclassified certain materials. King said the unit is evaluating non-hazardous substitutes.
 The Chemicals Group reduced total wastes about 9,200 tons and hazardous wastes about 8,600 tons, lowering volumes and rates about 12 percent in both categories.
 The Coatings and Resins Group generated about 7,400 tons less total waste, for 14 percent volume and five percent rate improvements. Hazardous wastes declined 4,700 tons, down 13 percent in volume and a four percent rate improvement.
 King noted that most unrecycled hazardous wastes from chemicals and coatings operations are safely eliminated through incineration.
