Solvay launches the first ISCC PLUS certified mass balance sulfone polymers

Solvay accelerates carbon footprint reduction of Udel PSU & Radel PPSU at Marietta, Ohio with certified circular feedstock

  • By ICN Bureau | April 19, 2023

Specialty materials leader Solvay has successfully earned independent third-party mass balance (MB) chain of custody accreditation under the widely recognized International Sustainability and Carbon Certification (ISCC-PLUS) scheme for its Marietta, Ohio (USA) site, producing polysulfone (PSU) and polyphenylsulfone (PPSU). The products – Udel PSU ReCycle MB and Radel PPSU ReCycle MB – are the first ISCC-PLUS mass balance compliant sulfone materials in the market and commercially available, world-wide.

“This is a major achievement as we strive to accelerate the transition of our industry towards a more circular economy through the substitution of fossil resources with sustainably and responsibly sourced alternatives,” says Dr. Bianca Shemper, Sustainable Sourcing Manager for Solvay’s Materials global business unit.

“While it aligns with the Solvay One Planet roadmap to mitigate the environmental impact of our operations and reduce our Scopes 1, 2 and 3 emissions2, it also provides a reliable way for our customers to contribute to a circular economy, and meet demanding sustainability targets and decarbonization goals by minimizing their own Scope 3 balance."

Solvay’s mass balance certified sulfone portfolio is based on monomers produced at the company’s Augusta, Georgia (USA) site, which received ISCC PLUS accreditation in 2022. The global availability of certified circular sulfone polymers will be supported by a major investment program at Marietta, significantly expanding Solvay’s overall capacity alone for PSU by 25% until 2024.

“The commercialization of our mass balanced sulfone grades is just another step as we continue to pioneer and innovate the high-performance materials market with responsible sourcing and production,” adds Claire Guerrero, Global Marketing Manager, Sustainability. “Additional certified circular polymers to be introduced soon will include grades of Ryton® polyphenylene sulfide and Amodel® polyphthalamide.”
