Section Seven INDUSTRIAL WASTES A. ELECTRONIC MFG. WASTES 57 USING A WASTE AUDIT APPROACH TO DETERMINE WASTE MANAGEMENT ALTERNATIVES AT A PRINTED CIRCUIT BOARD MANUFACTURING PLANT Robert C. Harries, Project Manager CANVIRO Consultants Waterloo, Ontario Canada N2J 1P8 Ken C. Bradley, Manager Waste Reduction Ontario Waste Management Corporation Toronto, Ontario Canada M1W 3E2 David Gardiner, General Manager Graphico Space Circuits Waterloo, Ontario Canada N2J 3Z9 INTRODUCTION The implementation of increasingly complex and stringent environmental regulations have forced industries in North America to reconsider their approaches towards waste management and to reevaluate the impact of environmental issues on their company's ability to survive in the market place. The emphasis is now on improving process efficiency, minimizing wastes and optimizing waste treatment and disposal practices to ensure compliance with discharge and disposal regulations. But how does a company go about assessing the status of their operations with respect to waste management? The best way to start is to conduct an in-plant survey or waste audit. To date, there has been little guidance available on how to go about conducting a waste audit but in 1987, CANVIRO Consultants (A Division of CH2M HILL Engineering Ltd.) developed an Industrial Waste Audit and Reduction Manual for the Ontario Waste Management Corporation (OWMC)1 which was designed as a practical guide to conducting an in-plant survey. This chapter describes the application of the waste audit approach to determine the waste management alternatives available at a printed circuit board manufacturing plant, Graphico Space Circuits, in Waterloo, Ontario. PRINTED CIRCUIT BOARD MANUFACTURING The wastewaters generated from printed circuit board manufacturing operations certainly present a challenge with respect to optimization of treatment processes. The manufacturing operations involve a complex series of physical and chemical processing stages, including deburring, electroless plating, electroplating and etching, and as a result, the wastewaters are complex, of variable composition and difficult to treat. To compound the treatment problems, many of the operations involve proprietary process chemicals, including chelators, whose formulations are not available to end user. A systematic approach to determine the major sources of waste and develop a sound strategy with respect to waste minimization and wastewater treatment is therefore essential. 43rd Purdue Industrial Waste Conference Proceedings, © 1989 Lewis Publishers, Inc., Chelsea, Michigan 48118.
