German silica producer Evonik has broken ground on what it says is a “significant” expansion at its Charleston site in South Carolina’s Berkeley County. This new development will boost the production capacity of precipitated silica by 50%, catering to the increasing demand from the tyre industry, particularly for green tyres in the US, it adds.
Evonik further adds that the expansion is a strategic move to solidify its presence in the region and demonstrate its long-term commitment to the silica business.
The expansion at the Charleston site will enhance local supply chains for the tyre industry and introduce circular raw materials to manufacture Ultrasil Silica, aligning with the sustainability goals of the tyre sector, the company claims.
Silica is essential for producing fuel-efficient tyres, which can reduce fuel consumption by up to 8% compared to conventional tyres. The demand for such tyres in North America is growing rapidly, driven by the need for improved fuel efficiency and reduced rolling resistance.
Evonik has consistently invested in modernising its silica production and making strategic acquisitions globally to strengthen its business. The Charleston facilities are part of a network of 18 precipitated silica production sites worldwide.
“With this expansion, our Charleston site will become a key hub for sustainable silica products in North America,” says Lauren Kjeldsen, Head of the Smart Materials Division, which includes the silica business. “The site’s strategic location, dedicated workforce, and advanced silica processing capabilities make it ideal for this expansion.”
Evonik has received investment incentives from the South Carolina Department of Commerce and Berkeley County Economic Development to expand its precipitated silica production at the Charleston location.
“Berkeley County is proud of its diverse industrial sector—one that is thriving and growing. Evonik’s expansion at Bushy Park in Goose Creek is a prime example of that success. We look forward to the company’s continued production in our community and the quality jobs that this project continues to create,” said Berkeley County Supervisor Johnny Cribb.
Evonik adds its focus on sustainability is a core aspect of this expansion.
“Our teams have worked diligently over the years to develop a comprehensive expansion plan,” says Emmanuel Auer, Head of the Silica Business Line. “This project will help us achieve our sustainability targets by combining the positive impact of our silica technologies with a low carbon footprint. It highlights our commitment to the Science Based Targets initiative.”
