  • Particleboard(PB) is one of the most commonly used wood-based composite materials, which can be prepared by utilizing any kind of low grade wooden materials like waste wood which contains formaldehyde itself. Therefore, PB have been of considerable interest, in issues regarding the formaldehyde emission problems. Wood wastes are carbonized by the carbonization kiln at $800^{\circ}C$. Charcoal has been known as a formaldehyde adsorber. Thus, in this study, we fabricated PBs with carbonized waste particles cores, to examine the possibility of developing less formaldehyde emitting boards. The physical and mechanical properties were evaluated by Korean Standard (KS F 3104). The moisture content of PBs ranged from 6.76 to 8.36%. Internal bond strengths decreased with the increase in the content of carbonized core particles. Formaldehyde emission showed minimum value at 25% of carbonized core particles, but the emission values increased when the amount of carbonized cote particles increased. When 25% of carbonized core particles was used, PBs met KS F 3104 standard properties.
