Indonesia has abundant renewable resources, including agro-industrial residues and wood wastes. Using this biomass as alternative raw materials in particleboard production can potentially respond to the increased global demand for wood-based products. This research was conducted to investigate the properties of particleboard from agro-industrial residues bonded with natural rubber latex (NRL)-based adhesive. Particleboards with the dimension of 40 ´ 40 ´ 1 cm3 and a target density of 0.7 g/cm3 were made using different compositions of agro-industrial residues (cassava stem, sengon wood waste, and rice husk) and NRL adhesive (10%, 15%, and 20%). The physical and mechanical properties were evaluated following the Japanese Industrial Standard A 5908 (2003) standard for particleboard. The results showed no remarkable differences in the physical properties of the PB panel, such as density, moisture content, water absorption, and thickness swelling, with different agro-industrial residues formulations and NRL adhesive content. By contrast, the mechanical properties of the board significantly increased with the increase in adhesive content. The optimum mechanical properties of the particleboard were obtained using 20% NRL adhesive and a composition of 40% cassava stem, 30% sengon wood waste, and 30% rice husk. The results showed that cassava stem waste, sengon powder, and rice husks have the potential to be used as a substitute for wood-based composite products, especially for non-structural applications.
