Abstract |
In the States of Oregon, Washington, Idaho, Montana, and California, 158 plywood plants generate an estimated 6.2 million gallons of waste per day from the cleanup of glue mixing equipment and glue spreaders. The waste is toxic and high in pollutional strength. Treatment of these glue wastes varies from plant to plant but generally consists only of solids separation or the removal of suspended matter. The objective of the study is to determine the magnitude and extent of the problem created by the disposal of glue wastes, review the characteristics of plywood glue wastes, and recommend methods of treatment for these wastes. |
