A sustainable alternative for wood waste is turning them into structural panels since it adds value to the raw material and contributes to the sector's circular economy. Strand-based composites such as oriented strand board is a natural fit for these wood wastes. A molded core composite with sandwich geometry with trapezoidal core guarantees significant increases in the stiffness of the panel, enabling its use as structural components in civil construction. Therefore, in this study, the mechanical properties of OSB sandwich panel with trapezoidal core produced with Balsa wood (Ochroma Pyramidale) waste agglomerated with bicomponent castor oil polyurethane resin (phenol free) were evaluated. The results indicate that the panel under study presented properties in the longitudinal direction that enable its use as a structural component.
