Solvay Inaugurates Europe's First Bio-Circular Silica Facility
Solvay has officially inaugurated its highly anticipated bio-circular silica production facility in Livorno, Italy, establishing the site as the first of its kind in Europe. The new plant represents a significant technological leap in the production of highly dispersible silica (HDS), a critical reinforcing agent used primarily in the automotive tire industry.
A Milestone for Circular Chemistry
The Livorno facility utilizes a proprietary process to produce silica from rice husk ash (RHA), an agricultural by-product that is typically landfilled or incinerated. By valorizing this silicate-rich waste stream, Solvay replaces the traditional energy-intensive method of manufacturing silica, which involves melting sand at high temperatures.
According to Solvay, this bio-circular approach significantly reduces the carbon footprint of the production process. The integration of RHA allows for a substantial decrease in CO2 emissions per ton of silica produced compared to conventional methods, aligning with the growing demand for circular raw materials in the chemical sector.
From Agricultural Waste to High-Performance Tires
The primary application for this bio-circular silica is the manufacturing of high-performance, energy-efficient tires. Highly dispersible silica is essential for reducing the rolling resistance of tires, which in turn improves a vehicle’s fuel economy and reduces battery consumption in electric vehicles.
By sourcing the silica from renewable bio-based feedstocks, Solvay enables tire manufacturers to increase the sustainable content of their products without compromising on performance, durability, or safety.
Advancing Carbon Neutrality
This investment underscores Solvay’s broader sustainability roadmap, which aims to phase out fossil-based raw materials and reduce Scope 3 emissions. The Livorno plant serves as a scalable model for future bio-circular projects, demonstrating that industrial performance and environmental stewardship can coexist within the complex supply chains of the automotive and rubber industries.
