Solvay advances worldwide circular silica strategy

-

Asian conversion marks a global shift toward sustainable sourcing, enabling tire makers to adopt circular materials at scale.

Solvay is accelerating its global circularity efforts by converting its highly dispersible silica (HDS) production in Asia to circular raw materials. As of 2026, plants in Qingdao (China) and Gunsan (South Korea) will adopt ISCC+ certified waste sand. This pivotal shift could enable over half of Solvay’s regional HDS capacity to become circular, directly supporting the tire industry's ambitious target of achieving 40%+ circular raw materials by 2030, with a worldwide rollout planned from 2026 onwards.


By replacing virgin raw materials with industrial waste, #Solvay develops technologies to reduce resource consumption and offers #tiremanufacturers a seamless, cost-effective, high-volume, drop-in circular #Zeosil® silica that requires no reformulation. 


This strategic move expands upon the successful conversion of Solvay’s Livorno (Italy) site, which uses rice husk ash, and reflects a coordinated, global approach to circular sourcing. It complements Solvay Silica’s broader sustainability roadmap, which includes implementing #lowemission technologies, such as electric furnaces, to reduce the product carbon footprint of #silica worldwide.

Today's KNOWLEDGE Share What Is Going Wrong in UK Plastics Recycling? Biffa shut its Sunderland plant. Viridor walked away from Avonmouth and Rochester. Yes Recycling Fife collapsed within a year. All three were backed by major investments All three had buyers lined up for recyclate All three are now offline This is not bad luck It is bad structure Over the next four posts I will break down: 1. Why cheap virgin imports are undercutting UK recyclers 2. How weak policy enforcement is fuelling market failure 3. What volatile PRNs and cheap exports are doing to infrastructure 4. Why demand from brands is softer than their promises Let’s start with the first: **Cheap Virgin Resin = Broken Economics** Virgin PE, PP, and PET have been flooding the global market. New capacity in Asia and the US has driven prices down 30 to 40 percent. Meanwhile, recycled plastic costs more to produce in the UK than it can sell for. We are asking UK recyclers to compete with materials made in places with – ...

Today's KNOWLEDGE Share “Robotic 3D printing can compete with traditional boatbuilding”, Simone Barbera and Mattia De Santis, Caracol V2 catamaran was printed in Italy at Caracol’s production center and headquarter in Barlassina, near Milan, with a Heron AM 400, Caracol’s robotic Large Format Additive Manufacturing (LFAM) platform. The lattest was specifically configured with a 7-axis robotic arm mounted on a rail, enabling the printing of parts up to 10 meters in length. How did the collaboration between V2 Group and Caracol come about? Simone Barbera : The collaboration between V2 Group and Caracol originated from a shared vision to revolutionize boat manufacturing through sustainable innovation. V2 Group, a Spanish-company specialized in nautical design and engineering, is seeking to develop electric vessels manufactured sustainably. On the other hand, Caracol, leader in robotic advanced manufacturing technology, had had years of experience working with Large Format Additive Ma...
