Investigation on possibility of utilization of MDF residues in its manufacturing process

In this study, possibility of using MDF wastes in MDF reproduction has been studied. Kinds of MDF wastes (HPL laminated, Melamine laminated and none laminated MDF wastes) and combination percent of MDF waste fibers with virgin fibers from MDF factory are assumed as variable factors in this research. After fabricating of MDF samples in laboratory conditions, the physical and mechanical properties of samples measured on the basis of the international standards. On the whole, results show that with increasing of average combination percent of waste MDF fibers, physical properties of MDF panels (especially thickness swelling) increase also. On the other hand, increasing of average combination percent of waste MDF fibers has definite effect on mechanical properties at 40 percent only. Based on the results, use of melamine laminated waste MDF and none laminated waste MDF is a most applied method in order to recycling of the MDF wastes.
