Relatively large drying collapse has restricted the utilization of low-density oil palm wood (OPW), an agricultural waste in the palm oil industry, for several decades. This work reports a simple pretreatment that allows OPW from all sections of the trunk having a thickness of up to 0.2 m to be severely kiln-dried up to the temperature of 200 °C without any drying defects and with relatively low drying shrinkage. Lightweight characteristics and mechanical, thermal and acoustic properties of the dried OPW are maintained. The pretreatment process involves water impregnation of fresh OPW followed by freezing the OPW below the eutectic temperature of sap (water–sugar) of about −10 °C before kiln drying. This strategy creates localized microcracks at the pit cavities that connect between the parenchyma cells. These microcracks allow the short-range flow of intercellular liquid at atmospheric pressure to compensate for the negative capillary pressure of the intracellular liquid inside the parenchyma cell cavity during drying. A fraction of the intercellular liquid plays a crucial role in the formation of microcracks during freezing and the reduction of cell collapse during drying. The technique is also found to be applicable to the drying of the porous trunk of other palm species.
