Analysis of the use of buriti and wood waste in the production of multilayer panels

Resumen

Agro-industrial residues are generated in large quantities and have the potential to be repurposed for the development of materials. Currently, there are few studies on the use of residues from the oil extraction process of buriti (Mauritia flexuosa) in the development of sustainable panels. Therefore, this study aimed to evaluate and characterize the addition of buriti residue in panels produced with wood and polyurethane resin. The buriti residue has a high extractive content (72%), while the wood residue has an extractive content of 10.14%. Multilayer panels with the addition of buriti residue showed a reduction in the Modulus of Rupture (MOR) value (2.17 MPa) compared to wood panels (9.11 MPa). Despite the reduction in mechanical properties, the panels exhibited low thickness swelling (~5%), demonstrating their potential for use in non-structural humid conditions, interior design, or furniture for outdoor areas.
