Revolutionizing Silica Production: Bio-Silica from Rice Husk Ash (RHA)

Silica, nature’s most essential building block, forms the very foundation of our planet—present in rocks, sand, and countless industrial applications. From ancient glassmaking to cutting-edge energy storage solutions, silica’s versatility has made it indispensable across industries. It serves as a dispersing agent, filler, and dehumidifier in sectors like rubber, tires, food, and pharmaceuticals. As long as human civilization thrives, the demand for silica will never cease.

However, traditional silica production comes at a cost. Extracted from silica ores through energy-intensive processes at extreme temperatures, conventional methods contribute to environmental degradation, hazardous silica dust, and unsustainable mining practices. The world is now shifting its focus to renewable, eco-friendly alternatives.

Enter Rice Husk Ash (RHA)—a game-changing, sustainable source of silica.

The Rice Husk Advantage

In rice-cultivating nations, rice husk is an abundant byproduct of rice harvesting. Often discarded as waste, this husk is a treasure trove of energy and silica. When combusted in boilers, the husk releases energy, leaving behind Rice Husk Ash (RHA)—a material containing 70% to 95% silica and residual burnt carbon.

This innovative approach not only addresses the global demand for silica but also transforms agricultural waste into a valuable resource, promoting a circular economy.

Pioneering Sustainable Silica Production

CPS, in collaboration with the Government of India and its Public Sector companies, is leading the charge in sustainable silica production. Leveraging proprietary technology, we are piloting the production of high-purity bio-silica from RHA.

Our first commercial plant, located at the CPS campus, is set to produce 6 Metric Tons Per Day (MTPD) of bio-silica. Rigorously tested in government laboratories, our bio-silica boasts:

– 99% purity

– Zero heavy metal content

– High surface area of 500 m²/g—making it ideal for a wide range of industrial applications.

Why Choose Bio-Silica from RHA?

1. Eco-Friendly Process:

Our production method operates at mild temperatures (up to 150°C), significantly lower than the 500°C+ required in conventional processes. This reduces energy consumption and minimizes environmental impact.

2. Heavy Metal-Free:

Unlike traditional silica, our bio-silica requires no additional purification for food-grade applications, ensuring safety and compliance with stringent industry standards.

3. Future-Proof Solution:

With global sanctions on silica mining on the horizon, RHA-derived bio-silica is poised to become the industry standard.
