ABSTRACT

The potentiality of rice husk as a good source of high technological materials is the subject of this research. Every year approximately 600 million tones of paddy are produced globally. This gives around 120 million tones of rice husk (RH) and 21 million tones of rice husk ash (RHA) annually. Major four uses of rice husk ash are in the steel, cement, refractory bricks and semiconductor industry. Besides these, it can be utilized in several other applications. In this literature review we have observed a preliminary analysis of the numerous reported utilization of rice husk. The use of rice husk for electricity generation in efficient manner is likely to transform this agricultural waste into a valuable fuel for industries and thus might help in boosting the farm economy and rural development and at the same time, waste disposal of rice husk is addressed while generation of employment will become possible as amorphous silica production from rice husks ashes will be formalized.

Keywords: rice husk, rice husk ash, industrial utilization, temperature, economic savings.
