Medium density fiberboard (MDF) is a nonstructural fiber-based panel that is composed of wood fibers bonded together with resin under heat and pressure. The fibers (either from rice straw or other woody materials) were refined using defibrated or refiner before mixing it with resin and wax.

Rice straw is produced as a byproduct of rice production at harvest. Rice straw is removed with the rice grains during harvest and it ends up being piled or spread out in the field depending if it was harvested manually or using machines. Ratio of straw to paddy ranges from 0.7-1.4 depending on the variety and growth.
