Brazil has seen a growing number of studies on the use of sawdust from industrial processes for the production of wood panels with added value to minimise forest exploration. In this article, five treatments with mixtures of wood particles from carpentry shops and sugarcane bagasse were examined. For particle homogenisation, granulometric composition studies were conducted; subsequently, three panels were made for each treatment, with the addition of 10% of polyurethane resin from castor oil, and evaluations were performed to determine the physical and mechanical properties of the panels. The physical and mechanical properties obtained with the mixtures with 50% of sawdust and 50% of sugarcane bagasse indicated that the production of panels for indoor use under dry conditions is possible.
