Utilization of waste paper and old corrugated carton (OCC) as a filler of urea formaldehyde resin on plywood manufacturing

The possibility waste paper (writing paper and newsprint) and old corrugated carton (OCC) utilization as a filler of urea formaldehyde resin on plywood manufacturing was investigated. The effect of type of filler as a variable factor on applicable properties i.e. water absorption and swelling after 2 and 24 hours, bending strength parallel and perpendicular to grain and shear strength on the interface was evaluated and the results were analyzed. The results of this study showed that utilization of waste paper and old corrugated carton as the filler decreased the water absorption and swelling and improved their mechanical properties. Since this materials caused to promote adhesion and improved the urea formaldehyde resin bond, it can be inferred that waste paper and old carton can act as an extender on the resin binding process.
