Covestro's Dr Christoph Gurtler and Prof Walter Leitner from Max Planck Institute for Chemical Energy Conversion and RWTH Aachen University have been nominated by the European Patent Office (EPO) as finalists in the ‘Industry’ category of the 2021 European Inventor Award for their role in developing a new technology for using carbon dioxide (CO₂).

The new technology enables climate gas CO₂ to be used as a raw material for sustainable plastics and forms the basis for a large number of marketable products. The process involves deploying chemical catalysts to drive reactions between CO₂ and a conventional raw material, resulting in creation of polymers in a more sustainable and economically viable way while firmly incorporating CO₂ in the process.

Gurtler, who is responsible for the development of new processes and products at Covestro, said, "This nomination is an important confirmation of our efforts towards making chemistry more sustainable. It shows how crucial patents are for the development process of a technology. It is a tremendous honour to be part of the award ceremony on behalf of the interdisciplinary team from product research, process development, marketing and the many other minds driving our invention."

Covestro and RWTH Aachen University founded the CAT Catalytic Center in 2007. "The scientific community has long had the desire to be able to use carbon dioxide as a supplier of carbon for plastics. Experts have been working on this issue for nearly half a century," explains Leitner.

The main roadblock for Gurtler and Leitner's team was that CO₂ forms chemical compounds only with great difficulty. The team combined industrial and academic expertise and finally achieved success by experimenting with different catalysts. The breakthrough was achieved by precisely controlling the reaction between CO₂ and petroleum-based propylene oxide in the presence of a customised catalyst system. "We collaborated closely to develop the right catalyst that led us to success," explains Gurtler.

The resulting product, which was introduced to the market by Covestro under the name cardyon, is already being used to produce soft foam for mattresses, for adhesives in sports floors, padding in shoes and in car interiors. Research projects have successfully demonstrated that CO₂ can also be deployed for insulating materials made of rigid foam and for surfactants.

Dr Markus Steilemann, CEO of Covestro, said, "The plastics industry can make a significant contribution to combating climate change by switching to greenhouse gas-neutral production. To achieve this, we need to break away from petroleum and use alternative raw materials such as CO₂. The nomination for the European Inventor Award is an endorsement of our company as a pioneer in this field. I would like to extend my sincere congratulations to the many colleagues, including those at our partners, who contributed to the development of the innovative CO₂ technology – a genuine sustainability highlight."

Gurtler and Leitner's team will compete with two other teams in the category at an online award ceremony scheduled for June 17. (TT)

The Yokohama Rubber Co., Ltd. developed a proprietary tyre mould design support system in April 2026, integrating finite element method (FEM) simulations and the company’s own artificial intelligence technology. This new tool is designed to augment the expertise of development personnel, enabling even less experienced staff to efficiently design moulds. It achieves this by providing data derived from numerous virtual experiments, which clarify how different mould design factors influence tyre characteristics.

The system accelerates mould development, lowers costs and minimises the rework typically associated with realising new designs. Furthermore, by fostering a multi-perspective understanding of the links between mould design elements and tyre performance, the tool equips Yokohama Rubber’s developers with fresh insights. These discoveries are expected to aid in creating tyres capable of achieving higher performance levels.

Developed under Yokohama Rubber’s HAICoLab AI concept launched in October 2020, the system addresses longstanding challenges. Mould design critically affects tyre traits, but traditionally understanding this relationship required expensive, time-consuming trial production and evaluations. The process also depended heavily on the tacit know-how of highly experienced staff, leading to variations in accuracy and development time based on individual expertise.

The support system resolves these issues through automated simulations and AI-based prediction and visualisation. It first generates numerous tyre FEM models with varied mould shapes and calculates their characteristics in a virtual space. These results train an AI surrogate model that instantly predicts design factor-performance relationships. By applying explainable AI technologies like SHAP and Partial Dependence Plots, the company’s developers can quantitatively visualise each factor’s impact, easily determining necessary adjustments to achieve targeted tyre characteristics.
