Covestro and Allmed Collaborate to Explore Recycling of Polycarbonate from Artificial Kidney Filters

December 25, 2025 - Covestro, a leading global supplier of high-performance polymer materials, and Allmed, an international specialist in blood purification, have announced a partnership to jointly research the recycling of discarded artificial kidney filters.

The study will explore the potential for recovering polycarbonate from medical devices and using it in new products containing recycled materials. This collaboration aims to develop a circular economic model for medical devices by validating both technical feasibility and economic benefits, while also navigating the complex regulatory environment of medical waste management. Allmed and Covestro are working with other UK partners—including Allmed's distribution partner Kimal, a leading regional hospital trust, and a specialized recycling company—to prepare for the first recycling trials.

"Circular economy in the healthcare sector is still in its infancy but holds enormous potential," said Wang Li, Global President of Covestro's Engineering Plastics segment. "Through this feasibility study, we aim to demonstrate that even complex medical devices like artificial kidney filters can be recycled and become an important source of high-quality polycarbonate recyclate, rather than being incinerated or landfilled."

Allmed is equally committed to achieving ambitious sustainability goals. "Blood purification devices are crucial for life-saving treatments but also require significant resources," said Ahmed Sorour, CEO of Allmed. "Our goal is to prove that excellent medical performance and ecological responsibility can go hand in hand."

Matt Press, CEO of the Kimal Group, added: "We are extremely proud that Allmed has chosen Kimal and the UK market as the pioneer for this exceptional and groundbreaking project."
