The goal of this work is to develop, carpentry residues which are sawdust of teak, and agricultural, the African locust bean pod (Parkia biglobosa), for the manufacture of particleboards. So we research a palliative to environmental problems caused by sawdust and the use of conventional binders. Teak sawdust particleboards were manufactured by varying the content of tannin powder of African locust bean pod. The mechanical, thermal and physical properties of these panels were determined using three-point bending test, tensile test, internal bond, swelling in water and thermal conductivity measurement. The bending test was used to determine the modulus of elasticity (MOE) and the modulus of rupture (MOR). The tensile test leads to the determination of the Young modulus (E) and the modulus of rupture (MOT). The immersion in water allows determining the rate of thickness swelling and water absorption after two and twenty-four hours. The thermal property evaluated is the thermal conductivity coefficient. This shows that the tannic powders can validly replace the conventional binders in the manufacture of particle board.
