The demographic growth drives agro-industrial production, generating a large amount of organic waste that compromises ecosystems. Among these residues, papaya seeds emerge as a highly interesting resource for manufacturing particleboard panels, offering an alternative to wooden panels and reducing the exploitation of forest resources. This study evaluates some physical and mechanical properties of prismatic samples made from papaya seeds combined with water and a commercial adhesive, in addition to manufacturing and testing a prototype of a structural insulated panel (SIP). The results indicate that, despite their high absorption and swelling, samples with 55% adhesive and pre-moistening showed greater flexural and compressive strength. Thus, papaya seed panels could sustainably reuse this waste, reducing environmental impact and adding value to an agroindustrial residue.
