Abstract: This invention relates to a process for making dimensionally stable reconstituted composite products from lignocellulosic material. By treating lignocellulose with high pressure steam to decompose and hydrolyse the hemicellulose, cellulose and lignin fractions of the lignocellulose and using those decomposition products as both a bonding and bulking agent, it converts, under heat and pressure in a moulding operation, the treated lignocellulose into moulded composite products such as panel boards and moulded articles. The composite products thus produced possess good physical and mechanical properties. Specifically, the dimensional stability in terms of the thickness swelling and linear expansion of panel boards such as fibreboards and particleboard, can be minimized to very low levels when the panel boards are made in high density.
