Due to the growing demand for wood and wood-based products, the industry, and researchers are focusing on using wood leftovers, such as agricultural waste and wood residues as alternatives to typical wood, as raw materials for composite manufacture. This study examined wood leftovers from Ceiba and Afzelia as a substitute raw material for particleboard production. Particleboard of Afzelia and Ceiba and the mixture of both wood species: (Afzelia at 100%, Ceiba at 100% and Afzelia and Ceiba at 50/50%) was manufactured in the laboratory target density 1000 kgmm-3. and mixing ratio was used (3.0:1.0 and 2.0:1.0). The physical properties (water absorption and thickness swelling after 24 and 48 hrs) and mechanical properties (modulus of rupture and elasticity) were evaluated following the European standards. The study found that there are variations in every factor used. For example, the mixture of Ceiba and Afzelia particles at 50/50% had the lowest water absorption value of 19.85%, followed by Ceiba particles at 100% and Afzelia at 100%. This suggests that boards made with this mixture of particles are more resistant to moisture intake than other types, but they swelled on average at 23.86%. For mechanical properties all main factors, and two factors interaction except wood species in modulus of elasticity were significantly different at 5 % probability level. This suggests that while variables such as wood species and mixing ratio were found to have no discernible effect on the modulus of elasticity, only the wood particle boards from Ceiba & Afzelia at 50/50% had the highest strength. They were also more rigid than the rest in terms of modulus of rupture. Additionally, the board composed of 3.0:1.0 and 2.0:1.0 mixing ratios. It was discovered that boards built of 3.0:1.0 were stronger than those made of 2.0:1.0.
