Belgian chemical company Syensqo has announced the development of a proprietary chemical recycling technology based on depolymerization to recover sulfone-based engineering polymers—PSU, PPSU and PESU—from both industrial scraps and post-consumer waste.

The new process enables the recovery of purified monomers that can be reused to produce new polyarylethersulfone (PAES) from the Echo range, which Syensqo markets under the Udel PSU, Radel PPSU and Veradel PESU brands.
These regenerated monomers can also be used in other thermoplastics or epoxy-based formulations, with no loss in performance.

“In times where circularity is increasingly crucial, we are leading the way to transform the industry with breakthrough sustainable solutions,” says Floryan De Campo, vice president of life solutions at Syensqo Specialty Polymers global business unit. “Our new circular PAES technology is a step forward for customers seeking to advance their sustainability goals. By enabling the recycling of sulfone polymers from both production scrap and end-of-life products, we help reduce carbon footprint and increase recycled content in a wide range of applications, from hemodialysis and water filtration to aerospace.”
