German chemicals and materials firm BASF revealed plans Wednesday for a “double-digit millions” expansion project at its Platinum Group Metals (PGM) refining facility in Seneca, SC to boost the site’s refining capacity for recycled precious metals from spent catalysts.

“This investment further strengthens our global leadership position in the spent automotive catalyst recycling market,” Tim Ingle, vice president, BASF Precious Metals Refining, Chemicals & Battery Recycling, said in a company release. “We are proud to enable the circular economy and to support our customers’, and our own, sustainability goals.”

The CO2 emissions from recycled metal are 90% lower compared to metal sourced from primary mines, according to the company.

BASF’s site in Seneca manufactures chemicals and precious metal catalysts, which are used to produce an array of goods like fertilizers, pharmaceuticals, and automotive emission catalysts.

No information was included in the release on when the project is expected to reach completion.

Earlier this month, BASF announced it entered into an agreement to invest in an expansion of its production capabilities for bacterial enzymes and other biotechnology products at Sandoz GmbH’s Kundl/Schaftenau campus in Austria. Production is slated to commence at the company’s new site in 2024.
