Abstract: Wood accounts for more than 40% of the production cost of clad of aglomerates panels and to meet industry demand and reduces the production costs of panels, the use of agro-industrial waste is an alternative. In this sense, the objective of this work was to evaluate the effect of the substitution of wood by soybean hull on the physical and mechanical properties of the panels. The panels were produced with a nominal density of 0.60 g cm-3. It replaced the percentages of 0, 25, 50, 75 and 100% of soybean hulls in relation to the eucalyptus particles. The particles were glued with 12% of the urea-formaldehyde. The pressing cycle comprised a pressure of 4.0 MPa and a temperature of 180 ° C for 15 minutes. The results showed that the conventional agglomerated panels produced with soybean residue showed an increase in their physical properties and a reduction of the mechanics as the replacement of the wood by residue was increased. It is concluded that, from the technical point of view, the physical and mechanical properties are met with a maximum substitution of the wood per soybean residue in the proportion of 28.9%.
