Solvay has converted its highly dispersible silica (HDS) production in Asia into circular raw materials. From 2026, the company’s plants in Qingdao in China and Gunsan in South Korea will adopt ISCC+ certified waste sand. This shift, Solvay says, could enable over half of Solvay’s regional HDS capacity to become circular.
By replacing virgin raw materials with industrial waste, Solvay develops technologies to reduce resource consumption. It offers tire manufacturers circular Zeosil silica, which does not require reformulation.
“Solvay’s circular silica helps improve fuel efficiency and EV range, offers long-lasting wear benefits and improves safety while advancing sustainability,” said An Nuyttens, president of Solvay’s Silica business unit.
