Resumo. ABSTRACTThis study aimed to evaluate the potential use of plywood, MDF and MDP to manufactureparticleboards. The resin urea formaldehyde (UF) was used in the production of the panels in proportionsof 6% and 10% based on dry weight of wood particles, along with 2% of catalyst, and 1% of paraffin.The experiment comprised 10 treatments with three replicates each, totaling 30 panels. The panelswere manufactured with residues in the proportions of 100%, 50-50% and 33-33-33%. The panels weresubjected to the following tests of physical and mechanical properties: board density, water absorption andthickness swelling - 24 hours, static bending, screw withdraw strength (surface and top) and tensionperpendicular to surface (internal bond).The results were evaluated according to the requirements of ENand ABNT standards. The general evaluation of the results of physical and mechanical properties ofthe panels showed the technical feasibility of the use of residues of MDF, MDP and plywood and theirmixtures for particleboard manufacture. The possibility of the use of these residues contributes interms of economical and environmental issues.
