Rice husk is a waste product from the rice mills and it is a headache to dispose it off. Now, National Physical Laboratories has a solution that kills two birds with one stone. With its technology you can dispose off the husk by making a valuable product—particle board.
The disposal of paddy harvest residue is a major problem, since both wheat and rice are long-duration crops, with a short period available between rice harvesting and wheat plantation.
India is the second largest producer of rice with the grain to straw ratio varying from 1:1.3 to 1:3, while Rice husk constitutes about 20% of the weight of rice. However, only a fraction of this residue is used as feed for ruminants and for other uses like manure, in brick kilns etc. The rest is mostly burned in the field that causes severe environmental hazards.
NPL has developed an eco-friendly solution for the management of the paddy harvest waste by converting it into particle board.
The particle board can be used for Furniture, False Ceilings, designer blocks to divide up rooms or outdoor areas & packaging material, Support structures of rooms, wall decorations, benches etc.
The know-how offers a simple process of production of particle boards from rice husk. It not only promises an additional support living for the people involved in farming, but also converts waste, which is otherwise a huge problem for farmers into a useful product and saves the environment.
