Composite production is one of the most attractive alternatives for the recycling of chromated copper arsenate (CCA) treated wood. In this study, wettability, vvater absorbance, and thickness svvelling of particleboard samples made from untreated, CCA-treated, oxaiic acid (OA) extracted, and bioremediated vvood particles were investigated. Wettability, water absorption and thickness swelling decreased in particleboard samples containing CCA-treated particles. However bioremediation of CCA-treated wood particles using Bacillus licheniformis has negative effect on board surface in terms of these properties.
