Abstract: This study investigated the properties of particle boards produced from composite of renewable lignocelluloses particles of sidaacuta plant, a non-toxic environmental friendly adhesive processed from extracted mucilage of cissuspopulnea stem and a commercial synthetic adhesive poly vinyl acetate. Cissuspopulnea adhesive and poly-vinyl adhesives were used as treatment at percentage mixing ratio of 0 and 20, 5 and 15, 10 and 10, 15 and 5, 20 and 0% by weight of total resin in the binding of processed sida acuta particles for the production of particle boards. 24 samples of dimension 150mm x 50mm x 10mm were produced in processing order of mixing, mat formation, hot pressing, air curing and trimming, thereafter subjected to flexural strength and physical tests to determine the boards Modulus of Rupture (MOR), Modulus of Elasticity (MOE), Internal Bonding strength (IB), Moisture Absorption capacity (MA) and Density of the boards. The mean of the data obtained from the tests conducted on the particle boards were tabulated and statistically analyzed using descriptive charts and ANOVA. Results obtained revealed that the board MOE, MOR, IB, MA and Density range between 18.6N/mm2 – 66.8N/mm2 , 0.135N/mm2 – 0.365N/mm2 , 0.56 X 10-3 N/mm2 – 1.31 X 10- 3N/mm2 , 9.4% – 12.3%, 0.40g/cm3 – 0.50g/cm3 respectively and Analysis of Variance showed no significant difference (P > 0.05) in the physical and mechanical properties of the boards at the percentage levels of treatments used. These results confirmed the suitability of sida acuta particles and cissuspopulnea adhesive as potential materials for the manufacturing of particle board, which implies that sida acuta particles can be used as substitute for non-available or non-renewable lignocelluloses particles while cissuspopulnea can partially or fully replace synthetic (poly vinyl acetate) adhesive to enhance production of low cost particle boards. This work therefore recommend further research on the use of cissuspopulnea adhesive as substitute for other commercial base synthetic adhesives used for particle board production.
