Rice Husk Particle Board : Alternative to wood and wood-based panel materials

Ajay0 · Jul 1, 2022

Scientists and researchers in India have developed an alternative to wood and wood-based panel products, using discarded agricultural wastes of rice husks processed to create boards with similar properties of wood. This is especially important in the face of shrinking forests and global warming trends.

Forest resources alone will not be able to meet the growing demand for wood and wood-based panel materials. Rice Husk Particle Board, made from readily available rice husk, can effectively replace the demand for panel materials. Additionally, these boards allow for the reuse of waste materials and can be made at a minimal cost. The Indian Plywood Industries Research & Training Institute (IPIR&TI), Bangalore, India, has developed a unique method for manufacturing boards from rice husk using suitable binding agents. This method is unique in terms of value addition and completes utilization of the husk without strict chemical composition requirements. In 1985, IPIRTI’s RHPB technology was transferred to the National Research Development Corporation (NRDC) of New Delhi, India, a Government of India enterprise, for further development and commercialization. In 1987, NRDC licensed the technology to M/S Padmavathy Panel Boards Pvt. Ltd (PPBL), Bangalore, Karnataka, and cooperated with PPBL to solve the difficulty of moving technology from the lab to the factory.

The Corporation and the entrepreneur worked together to supervise the project. In a world record time of 18 months, the unit was put into production. The company is currently in regular production and has produced several goods to fulfill a variety of needs. As a substitute for wood-based panel boards, the product is well-received on the market.

Rice-growing countries around the world have enormous challenges in disposing of rice husk trash, which poses a major environmental concern if burned. Rice Husk Particle Board manufacturing method developed at the Indian Plywood Industries Research Institute in Bangalore has emerged as one of the finest answers to this problem because it helps to maintain eco-balance and conserve the eco-system. In India, as well as many other rice-growing countries, patents have been submitted.

This board has shown to be a viable alternative to wood in a variety of applications. Furthermore, these boards can be created to be decorative. Several Indian companies have been granted licenses, and a turnkey facility has been established in Malaysia. The company has also created floor tiles (made of rice husk), fire-resistant doors, and other products with a granite-like finish. Furthermore, during the Gujarat earthquake, the technology’s licensee assisted in the construction of a huge number of low-cost houses.

Rice husk is the most readily available of all agricultural wastes. It is a by-product of the country’s most major agro-based sector, paddy milling. Rice husk is produced in the country in quantities of 2 million tonnes per year.

Using modified phenol cardanol formaldehyde resins, IPIR&TI has perfected a process for producing multilayered particleboard. The panels’ strength qualities meet the applicable specifications’ requirements. The boards have a strong termite resistance and are fire-resistant. The proposed method has a large environmental impact because it uses rice husk to avoid deforestation in one way.

This shows that research and technology can be used to change seemingly useless waste materials into useful products at minimal costs and which will aid conservation of forests and trees.
