Eco-panels Based on Wastes from Urban Trees and Castor Oil Polyurethane Resin

Urban trees have aesthetic functions and mit igate high temperatures, however their maintenance requires constant pruning. This work aimed to apply the tailings resulting fro m tree management in particleboard production. Particles fro m urban tree pruning of Jatoba, Canelinha and mixture o f these species were used, in addition to castor oil resin as adhesive. Particleboard was evaluated according to NBR 14810:3 and results compared with the main standards . Panels presented satisfactory values for water absorption and thickness swelling. For mechanical properties, particleboards made fro m Jatoba showed better results. Thus, it's possible emp loy residues from pruning high density urban tree in particleboard.
