Innovation in Silicone Recycling
Elkem ASA has successfully validated a proof of concept for a new mechanical recycling process for High Consistency Rubbers (HCR). This innovation allows for the recycling of crosslinked HCR waste, with reintegration rates exceeding 50%, while maintaining excellent mechanical properties. This development supports scalable circular approaches for high-performance silicone elastomers, aiming to reduce waste and carbon footprint.
Project RENOV
The innovation is part of the RENOV project, which focuses on the recycling and reincorporation of elastomer materials. Launched in 2023, the project involves collaboration between Elkem, Hutchinson, Nexans, and CNRS-affiliated laboratories IMP, CP2M, and ISA, with support from the French environment agency ADEME. The goal is to develop technologies for recycling crosslinked elastomer waste and reintegrating it into formulations with virgin elastomers for identical applications.
Market and Application
The project also aims to evaluate market acceptance for new materials like mechanically recycled HCR, identifying applications that offer the most environmental and commercial benefits. This development expands Elkem's silicone recycling strategy, which now includes both chemical and mechanical recycling routes, allowing for tailored solutions based on waste type, carbon footprint goals, and desired product performance.
Upcoming Presentation
Elkem will showcase samples of the recycled material and discuss their mechanical recycling technology at K 2025, the leading trade fair for plastics and rubbers, scheduled from October 7 to 14, 2025, in Düsseldorf, Germany. Attendees can meet Elkem's technical and sustainability experts at Hall 7A, stand B16.
