Method for the production of artificial wood board

A method for the production of artificial wood board without the addition of a binder, wherein the method comprises the following steps:

• a) milling of lignin containing plant material to obtain a milled mixture comprising particles with a particle size of less than 5 mm, wherein said lignin containing plant material comprises coconut husk pith;
• b) conditioning said milled mixture at a RH of between 50%-65%, at a temperature of between 20-24° C. for a period of between 5 to 12 days to obtain a conditioned milled mixture having an equilibrium moisture content of between 16% to 25%;
• c) homogenising said conditioned milled mixture to produce a homogenous mixture having a density of between 0.1-0.25 g/cm3;
• d) cold-pressing the homogenous mixture obtained in step c to obtain a brittle board having a density of between 0.3-0.6 g/cm3;
• and
• e) hot-pressing said brittle board to reach a density of between 1.2 to 1.4 g/cm3 to obtain an artificial wood board.
