Abstract
The main objectives of this study were to evaluate the biodegradation behaviour of experimental particleboard bonded with modified 30 % of PVOH, 70 % of Oil palm starch and 3 % of nano silicon dioxide (SiO2). Boric acid at 2 % was also added as a cross-linker to PVOH in modified oil palm starch to enhance ...

The main objectives of this study were to evaluate the biodegradation behaviour of experimental particleboard bonded with modified 30 % of PVOH, 70 % of Oil palm starch and 3 % of nano silicon dioxide (SiO2). Boric acid at 2 % was also added as a cross-linker to PVOH in modified oil palm starch to enhance decay resistant for the samples. All the particleboards were evaluated by soil burial, borer and fungal strains tests. The samples were then compared with particleboard bonded with native oil palm starch and commercial urea formaldehyde (UF). The results indicated that particleboards bonded with modified PVOH/Oil palm starch were more resistant than particleboard bonded with their native starch and thus can be used as a potential binder for green particleboard in future. The SiO2 also showed a significant effect towards modified oil palm starch as compared to their native oil palm starch and commercial binder.

In this study, physical, mechanical and flame retardant properties of oil palm trunk particleboards were evaluated. The properties of oil palm trunk particleboards were compared with polylactic acid (PLA) added board, where PLA was added as a function of natural binder, and PLA added board with calcium sulfate (CaSO4) and magnesium oxide (MgO), where CaSO4 and MgO was added as a function of flame retardant additives. The thickness swelling, modulus of rupture and internal bond strength properties improved as addition of PLA. In comparison to addition of additives, PLA added board with CaSO4 exhibited higher physical and mechanical properties than PLA added boards. The flame retardant properties of PLA added oil palm trunk board with CaSO4 showed higher value of LOI compared to others. Overall results revealed addition PLA improved the physical and mechanical properties of oil palm trunk particleboard and the flame retardant properties increased with addition of additives namely MgO and CaSO4.
