Stable Catalysts for Green Chemical Manufacturing

Olefin metathesis is a Nobel Prize-winning reaction that holds great promise for more sustainable chemical manufacturing. It enables the efficient transformation of molecules and is already used to produce everything from pharmaceuticals to plastics. However, the catalysts that power this reaction have long struggled with stability issues. Under real-world industrial conditions, they tend to break down, making processes inefficient and costly. This has slowed the broader adoption of olefin metathesis in large-scale green manufacturing. Researchers at the University of Bergen and the University of Ottawa have achieved a major breakthrough. Building on years of research into how these catalysts degrade, they have developed a new generation of ruthenium-based catalysts that are significantly more robust. As part of this project, several new catalysts have been synthesized and tested. All tested variants have shown far greater resistance to the key decomposition pathways that previously limited industrial use. In several benchmark reactions, they delivered significantly higher yields than today’s commercial alternatives. The results have been so promising that a patent application has already been filed to protect the innovation. The team has also initiated dialogue with major industry players, and as a direct follow-up, a Proof of Concept (PoC) project has been applied for and granted, ensuring continued momentum toward commercialization. This innovation, supported by the results from the qualification project, paves the way for greener and more cost-effective chemical manufacturing. It supports the transition to a more sustainable industry and aligns with global goals for cleaner production and climate-friendly technologies.

The project has strengthened competence within research and industry by developing stable ruthenium-based olefin metathesis catalysts, supporting more efficient and sustainable chemical processes. A patent has been filed, and collaboration with industry has been initiated, paving the way for commercialization. The project has also contributed to training in sustainable chemistry. In the longer term, the results support green chemical manufacturing, promote the use of renewable feedstocks, and contribute to enhanced industrial competitiveness and green growth.
