Project report for Rice husk

India alone has produced around 31 million tons of rice husk and thus generated 4.65 – 5.58 million tons. India has a major agribusiness sector which has achieved remarkable successes over the last three and a half decades. Agricultural waste or residue is made up of organic compounds from organic sources such as rice straw, oil palm empty fruit bunch, sugar cane bagasse, coconut shell, and others. Rice husk from paddy (Oryza sativa) is one example of alternative material that has a great potential. Rice husk a major by-product of the rice milling industry, is one of the most commonly available lignocellulosic materials that can be converted to different types of fuels and chemical feedstocks through a variety of thermochemical conversion processes. Complete burning of Rice husk produces rice husk ash which further utilized for different applications like power generation, fuel in boilers and so on.

Rice husk is an agricultural residue abundantly available in rice producing countries. The husk surrounds the paddy grain. This husk is used as fuel in the rice mills to generate steam for the parboiling process. This husk contains about 75 % organic volatile matter and the balance 25 % of the weight of this husk is converted into ash during the firing process, is known as rice husk ash. Rice hulls or rice husks is the hard-protecting coverings of grains of rice. In addition to protecting rice during the growing season, rice hulls can be put to use as building material, fertilizer, insulation material, or fuel. Rice hulls are part of the chaff of the rice. Rice hulls are the coatings of seeds, or grains, of rice. The husk protects the seed during the growing season and is formed from hard materials, including opaline silica and lignin. The hull is hard to eat or swallow and mostly indigestible to humans because of its enriched fiber components.

The global rice husk ash market is projected to reach INR 1900 Crores by 2021, at a CAGR of 5.4% from 2016 to 2021. The rice husk ash market is expected to witness market growth at a rate of 4.7% in the forecast period of 2021 to 2028. The rice husk ash market provides analysis and insights regarding the various factors expected to be prevalent throughout the forecast period while providing their impacts on the market’s growth. The increase in demand for the product from various industries is escalating the growth of rice husk ash market.

The increase in demand for the product from the Asia-Pacific and the Middle East regions especially acts as one of the major factors driving the growth of rice husk ash market. The increase in demand for rice husk ash in ceramics and refractory, steel industry, rubber industries, building and construction and high use of RHA to produce high purity silica accelerate the market growth. The increase in the preference for rice husk ash instead of silica fume and fly ash in the cement and construction industry and rise in adoption because of low manufacturing and raw material cost, further influence the market. Additionally, high use in various processes, urbanization and industrialization, and expansion of end-use industries positively affect the rice husk ash market. Furthermore, increase in demand from the emerging economies extends profitable opportunities to the market players in the forecast period of 2021 to 2028.
