Logs processing produce large quantity of waste, ca. 60% related to original solid volume. This material is usually employed in power generation with the production of ash and soot, or improperly deposed, causing environmental problems. In this context, the present study aims to produce and evaluate the physical and mechanical performance of particleboards produced with waste from the processing of Dipteryx odorata, a tropical wood species whose chemical and physical characterization was also performed. The production of particleboards was based on a factorial design (2(2) +1), in which the quantities of waste and resin were analyzed. For the physical and mechanical analysis, twenty-four panels were produced, using different amount of residues (1000, 1300, 1500 g) and resin content (10, 12.5 and 15%). Specimens were obtained from the panels in order to determine their: density; compaction ratio, thickness swelling and water absorption (2 and 24 h); modulus of rupture and modulus of elasticity in static bending; internal adhesion; and screw pullout. Panels with 1500g (10 and 15% of resin) were those with the best mechanical results, higher than the minimum specified by the NBR 14810-3 (2006), confirming their potential in producing particleboards.
