The process described herein presents a unique method and means of manufacturing medium density fibreboard (MDF) using agricultural plant stalks. The plant stalks are first depithed. The stalks are then broken down into fiber-like threads and made into fiber bundles. These fiber bundles are then combined with a resin component and a wax component, and the resulting mixture is cured. The MDF is economical to manufacture than prior art fibreboard in that it does not necessitate the use of expensive MDI resin. Further, the fibreboard is environmentally friendly in that it provides a beneficial use for agricultural waste.
