Iran is not rich in forest land and only 7.5 per cent of country covered by forest. So Iran has to import wood based panel annually. It is estimated that 100.000.000 Date Palms trees covered an area at about 770.000 ha around world, and Iran has got 220.000 ha. Because of several reasons Date palm trees should be pruned and each tree produce 10-20 kg residues annually. In this study, for making boards Date Palm pruning residues as a raw material and employed two kind of synthetic resin ( UF & MUF ) as the binder. Three boards were manufactured in both Laboratory & Pilot plant sdcale for each combination of variables, and samples of all the boards made were tested by the methods of ASTM to obtain mean values of bending strength, and Internal bond strength (I.B). In addition samples of each type of board were tested for thickness swelling and water absorption after soaking in water for 2 hours and 24 hours respectively. Also all boards were tested for formaldehyde emission and it was the first time which such test is done in Iran. The results of this study show clearly that boards have higher strength than the MDF property requirements which is recommended by ASTM. As the results of this study were satisfactory, a patent based on achieved result under title of, Date Palm ( Phonex dactelifera) pruning residues as a raw material in MDF production, was registered in the patent office in Iran and the project has been chosen as one of the best project among 700 projects and received a gold medal.
