Our technology is to produce highly dispersible silica and precipitated silica from rice husk ash based on zero waste chemical process using rice husk ash as feed and produces precipitated silica and other by-products. The technology can extract upto 70% silica from the ash. The technology has already been commercialized. The technology can produce silica for all major applications, including tires, rubber, footwear, paints, coatings, toothpaste, food & pharmaceuticals. Rice husk ash is a leftover generated after using rice husk as fuel in industrial boiler and power plants. Every year more than 20 million tons of rice husk ash is generated globally which is landfilled or dumped in open grounds, affecting the environment negatively. Our technology will use the ash and extract the advanced grades of precipitated silica, including highly dispersible silica from it. Highly dispersible silica is an advanced grade of precipitated silica which is used in energy efficient green tires to improve the performance of tires. It reduces the rolling resistance of tires while improving the grip. It results in improving the mileage of vehicles while reducing the greenhouse gas emissions from the vehicles. The technology has various advantages over conventional precipitated silica production technologies. The conventional technology uses sand as a base material for silica whereas our process uses rice husk ash as a base material for silica. The technology can produce better quality silica as compared to existing conventional methods. USES/APPLICATION : Tires Toothpaste/Oral care Paints, Coatings & Inks
