Rice Husk Ash to highly dispersible silica

Technology Description

Rice husk is used as fuel in industries as its calorific value is very high. Rice husk ash is a waste generated after utilization of rice husk as fuel. Every year more than 2-3 million tons of rice husk ash is generated in India. As it doesn’t have any commercial application, it is generally landfilled or thrown in open grounds. Open dumping of rice husk ash affects the environment negatively as this ash has high pH value and affects fertility of the land. This technology uses this ash as raw material and extracts highly dispersible silica from it. Silica is a chemical compound with application in various industries including rubber, tire, food, dental etc. This technology produces an advance grade of silica which has an application in tire industry. This grade is used as filler in tires and it improves the performance of tires. It reduces the rolling resistance of tire, which results in reduction in fuel consumption of vehicle and reduction in emission of green house gases from the vehicle.
