Solvay S.A. (Brussels, Belgium) is investing at its Livorno site, in Italy, to launch the company’s first unit of circular highly dispersible silica (HDS), made with bio-based sodium silicate derived from rice husk ash. This new breakthrough silicate process provides a circular solution as it gives a second life to rice husk in a local value chain. Coupled with renewable energy integration at the plant, it will allow Solvay to achieve a 50% reduction in CO2 per ton of silica. This will make the Livorno site Europe’s best in class silica production site in terms of CO2 footprint. Production is expected to start by the end of 2024.
The Group will gradually replace its existing Zeosil portfolio with circular HDS, providing a circular solution for tires that will contribute both to increasing the use of sustainable raw materials and reducing the tire industry’s CO2 footprint. This new generation of precipitated silica will also address the needs of the home & personal care and the feed & food industries.
