Solvay brings rice husk silica plant online

February 2, 2026 |

In Italy, Solvay has inaugurated a bio-circular silica facility at its Livorno, site. The new unit produces highly dispersible silica using biobased 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 and creates a local circular value chain.

The new facility will also meet widely expected rules for tires in the European Union and supports customers’ sustainability goals.

“By acting now, Solvay is helping tire manufacturers prepare for future EU requirements and meet their own sustainability goals,” Philippe Kehren, CEO of Solvay, said in a press statement. “Livorno is a tangible example of how we turn circular economy principles into industrial reality, enabling progress for generations.”

Jana Striezel, Head of Purchasing at Continental Tires, said the company is looking forward to integrating more rice husk ash silica as a recycled material in its tire production. “We are keen on innovative, renewable and recycled materials because they support our ambitious sustainability roadmap.”
