Performance of Particleboards Made from Forest and Agricultural Wastes

Wood-based panels have been widely used around the world replacing solid wood in various segments of the industry such as furniture panels structures and other building components. The large volume of waste generated by agro industry enables the development of alternative and sustainable materials highlighting the particleboard. This paper presents a study about production and evaluation of particleboard of Eucalyptus grandis and oat hulls bonded under pressure with two types of resins (polyurethane based on castor oil and urea formaldehyde). Physical-mechanical performance of the panels produced was evaluated based on ABNT NBR 14810:2006 ANSI 1999 BS EN 312: 2003 and CS 236-66: 1968. A variance analysis (ANOVA) evaluated the factors Eucalyptus grandis with mass ratios of 70 85 and 100%; oat hulls in proportions of 15 30 and 100%; adhesives in proportions of 10 12 and 14% and the combination of both in each of the response variables (physical and mechanical properties) evaluated. Results showed good physical-mechanical properties in some cases much higher than national and international codes requirements.
