Carbonized panels were prepared from waste phenol-formaldehyde resin and magazine paper by gas phase activation method. The bending properties and specific surface area of these carbonized panels were investigated. The modules of elasticity (MOE) was increased with carbonized treatment for raw panels. However, the MOE and modules of rupture (MOR) were decreased with carbon dioxide gas activation. Thus, decomposition of organic substance including waste phenol-formaldehyde resin through the carbon dioxide activation process influenced the decrease of MOE and MOR. The specific surface area of carbonized panel correlated with the yield of activate treatment, and the ash contents of waste phenol-formaldehyde resin influenced the specific surface area.
