- The facility uses bio-based sodium silicate from rice husk ash.
- CO₂ emissions are reduced by 35% per ton of silica.
- Solvay aims to convert all silica sites to ISCC® PLUS certified materials by 2026.
- Tire manufacturers can achieve up to 15% recycled materials in tires now, targeting 40% by 2030.
Introduction
Solvay has inaugurated a bio-circular silica facility in Livorno, Italy, marking a significant step in Europe's move towards sustainable industrial practices.
Innovative Process
The facility produces highly dispersible silica using bio-based sodium silicate derived from rice husk ash, an agricultural byproduct. This process reduces CO₂ emissions by 35% per ton of silica compared to traditional methods.
Strategic Goals
This initiative aligns with the European Green Deal and the upcoming Ecodesign for Sustainable Products Regulation (ESPR). It also supports tire manufacturers in meeting future EU sustainability requirements.
Global Strategy
Part of Solvay's global circular silica strategy, the Livorno site is the first to use rice husk ash. By 2026, Solvay plans to convert other silica production sites worldwide to use ISCC® PLUS certified raw materials.
Impact on Tire Manufacturing
By adopting Solvay’s circular silica, tire manufacturers can achieve up to 15% recycled or renewable materials in their tire composition, contributing to a target of 40% by 2030.
Conclusion
The facility strengthens Solvay’s leadership in silica for energy-efficient tires, reducing rolling resistance and fuel consumption, while reinforcing Italy’s role in green innovation.
