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

Abstract

Urban trees have aesthetic functions and mitigate high temperatures, however their maintenance requires constant pruning. This work aimed to apply the tailings resulting from tree management in particleboard production. Particles from urban tree pruning of Jatobá, Canelinha and mixture of 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 from Jatobá showed better results. Thus, it’s possible employ residues from pruning high density urban tree in particleboard.
