The aim of the present paper was to study the effect of some particle recovery parameters on the quality of hydrothermally recycled particleboards. The research was carried out in two phases: rough evaluation of various recovery parameters and determination of the recycled particleboard properties. It was concluded that the optimum group of hydrothermal recovery parameters (among those tested in this investigation) were 45% water retention/150°C temperature/10 min duration. This conclusion relies on the below-mentioned facts: the conditions of recovery parameters 45%/150°C/10 min resulted in the lowest agglomeration ratio in the recovered material in relation to the other recovery parameters examined in the first and second phases. Concerning the properties of the recycled particleboards, it was observed that the boards that were produced utilising the above-mentioned recovery parameters showed the best internal bond, surface soundness, modulus of elasticity in bending, hygroscopic properties and free formaldehyde content values.
