This study investigated the utilization of resin impregnated decorative and overlay paper wastes obtained from the edge trimming of partially cured, dried papers as a binder in the manufacture of the light medium density fiberboard (MDF). The light MDF panels were prepared from various mixtures of the softwood fiber and hammer-milled impregnated paper waste, 95/5, 90/10, and 80/20 wt%. The results of the experiments showed that the dimensional stability and mechanical properties of the light MDF panels were improved by adding hammer-milled melamine impregnated paper waste. The resin impregnated paper waste could be evaluated as a binder for the manufacturing of the light MDF panels having better dimensional stability and mechanical properties than standard light MDF panels used in interior applications.
