"The primary object of the present invention is to invent a board which is high strength and low cost. The board shall compose of agricultural wastes which need not be ground into particles and hence eliminate the use of a grinder. Even though without grinding the waste materials, the board can still have high strength due to original material particle size at its maximum and this reduces the use of more expensive material such as binder and hardener.
Another object of the present invention is to invent a board produced from various organic agricultural wastes which are abundant, biodegradable, reusable and inexpensive. As a result, the amount of wastes disposal into the environment can be reduced.
At least one of the preceding objects is met, in whole or in part, by the present invention, in which the embodiment of the present invention describes a method of producing board comprising mixing agricultural wastes of rice husks, rice straws, bagasses, banana leaves and the like with a binder and a hardener and compressing said mixture at a temperature ranging from 100??C to 200??C under pressure of 120 kg/cm2 to 200 kg/cm2 in a time period of 10 minutes to 40 minutes.
