It was found out that the solvolysis of wood using polyethylene glycol converted wood to some organic solvent soluble products about thirty years ago. It has been expected that this method converts waste wood from woods and factories to useful materials. There is a lot of study about utilization of solvolysis products as raw material of plastics or chemicals. One of the most important problem for utilization of the solvolysis wood is the processing methods is restricted within narrow limits because the solvolysis wood have high viscosity. However, the viscosity could be decreased by the solvolysis wood suspended into water, and the solvolysis wood could be sprayed to wood elements. In this study, wood composite panels were constructed by using the solvolysis wood as adhesives. Further, the solvolysis wood was treated with ozone and the effects of ozone treatment on adhesion properties were investigated. As a result of mechanical properties measurements, it was shown that, the wood composite panels constructed with the solvolysis wood have good bending properties and the mechanical properties improved with increasing the amount, of ozone added to the solvolysis wood.
