Abstract

This work seeks to produce wood-based panels with Amazon wood sawing residues and castor oil-based polyurethane resin as binder. Three types of panels were produced, with the following resin proportions: 25%, 30%, and 35%. Physical and chemical tests were performed to assess the potential for using this residue, and physical and mechanical properties of the panels were evaluated. Tukey test was performed with a 5% probability to verify the significance between the means for the different types of panels. The results show that the produced panels have a high density (~800 kg/m³), modulus of rupture (~11 N/mm²), which meet the physical properties and modulus of rupture (Non-structural) required by Brazilian particleboard standards, demonstrating its potential in the use of non-structural panels in furniture or finishing. However, the panels did not meet the modulus of elasticity (~900 N/mm²) property, indicating the need to propose ways to improve this property in such panels in future research
