Here we present a study of the potential use of agro-industry residues (sugar cane bagasse) in order to add value to these materials through the manufacture of particle boards and evaluation of the physical and mechanical performance. For this, we used polyurethane monocomponent and bicomponent resin based on castor oil. The quality of the products was evaluated based on the requirements of normative documents NBR 14810 (ABNT, 2006b), with determination of the density, swelling, absorption, elasticity modulus (MOE) and strength in static bending (MOR). After analyzing the results, the panels presented average density 0.93 g cm-3, average MOR and MOE 24.4 and 2432 MPa, respectively, being classified according to the indicative of the ANSI A208.1 (1993), as material of high density, recommended for industrial use. The resin based on castor oil was efficient as a matrix polymer for making composites based on sugar cane bagasse.
