<br/><br/> Undoubtedly, solid waste became evident in the growing global population and increasing<br/>industrial activities. By executing some enactments, formulating different alternatives, and<br/>focusing on having sustainable yet eco-friendly cities and communities, solid waste<br/>material and other industrial waste can be used in a way that proper disposals are being<br/>highlighted. Thus, by the use of Mahogany seed pod, researchers have utilized its<br/>practicality to create a new type of construction material focusing on a wood-based<br/>product. Due to that reason, researchers investigated the compatibility of Mahogany Seed<br/>Pod and Isocyanate Resin as binders for particleboard. Through study, researchers have<br/>developed a Particle Board using Mahogany Seed Pod and Isocyanate Resin as binders to<br/>produce an alternative material for construction use. The researchers created five mix<br/>designs with MSP: isocyanate 97:3, 95:5, 93:7, 91:9, and 89:11. Each board was replicated<br/>3 times for a more accurate result. The board dimensions of 40cm x 40cm x 1.2cm with a<br/>target density of 0.80g/cc. The board underwent Density Variation (DV), Water Absorption<br/>(WA), and Thickness swelling Test (TS) for Physical properties and Inter Bond strength<br/>(IB), and Modulus of Rupture (MOR) for Mechanical properties. Results under different<br/>tests showed that Thickness Swelling (TS), Face Screw Withdrawal (FS), and Internal<br/>Bond Strength (IB) passed the requirements under PNS standard 230: 1989 for IB and FS<br/>and PNS ISO 16893:2017 for IB; Highlighting MD4 as the best mix design with its 91:9<br/>mix ratio.<br/>Keywords: Mahogany seed pod, alternative materials, isocyanate, particle board
