Researchers from RWTH Aachen University, the Max Planck Society, and Covestro AG have reached the finals of the 2019 Deutscher Zukunftspreis for their groundbreaking work on the use of carbon dioxide as a raw material.

A large interdisciplinary team led by Professor Walter Leitner, Dr. Christoph Gurtler, and Dr. Berit Stange has developed a process that uses CO2 in the production of plastics, significantly reducing the demand for crude oil.

Yesterday, the nominated research teams presented their innovations at a public event in Berlin. The Munich-based team Celonis won first place and received the high-profile award from German Federal President Frank-Walter Steinmeier.

'It is a great honor to be among the finalists for the Deutscher Zukunftspreis, which provides a further boost to our research at RWTH Aachen University and the Max Planck Institute for Chemical Energy Conversion,' said Leitner on Wednesday evening in Berlin. Leitner is chair of Technical Chemistry and Petrochemistry at RWTH and director of the Max Planck Institute for Chemical Energy Conversion. Fellow nominee Christoph Gurtler is responsible for new processes and products at Covestro AG, while his colleague Berit Stange is in charge of the transition to a circular economy for polyurethane plastics.

RWTH Rector Ulrich Rudiger was also present at the event. 'We are very proud of Professor Leitner and his team. Their achievement demonstrates not only that we at RWTH are particularly successful in investigating the great technological challenges facing the world today, but also in putting our research into practice in collaboration with strong external partners,' said Rudiger.

Vast amounts of carbon dioxide are emitted wherever fossil fuels are burned or processed - whether in the industrial, mobility, or energy sector. The chemical industry, however, requires carbon - a component of the greenhouse gas carbon dioxide - as a building block for a wide range of products, including plastics. It is usually extracted from crude oil, natural gas, or coal. The nominated team has taken the first step towards closing the carbon cycle by using a portion of such carbon dioxide emissions for industrial production.

This use of CO2 is one of the 'dream reactions' being explored at the CAT Catalytic Center in Aachen, a joint facility of RWTH and Covestro. In the process, part of the petroleum-based raw material for chemical production is replaced by carbon dioxide. Up to 5,000 metric tons of polyol can already be produced annually in Covestro's pilot plant. This substance is then further processed into polyurethanes, which are used as foam in mattresses for example. Other fields of application for polyurethanes include soft foam in car seats and rigid foam in insulating materials.

This use of carbon dioxide was made possible by a breakthrough in catalysis research. Since carbon dioxide is chemically inert and reluctant to form chemical compounds with other substances, a tailor-made catalyst was needed to control the reaction for it to be economical and efficient. Catalysts cause reaction partners to form compounds by lowering the activation energy for conversion and steering it in a desired direction. The experts at RWTH and Covestro have found a suitable catalyst for incorporating CO2 into the polyol.

As Walter Leitner explains: 'The new process illustrates how chemistry can contribute to a sustainable future with the help of closed carbon cycles. The cooperation with Covestro in the CAT Catalytic Center at RWTH Aachen University is a prime example of what collaborations between fundamental academic research and industrial innovation could look like. Along with Christoph Gurtler and Berit Stange, we represent many of our colleagues who have contributed to the success of this project with their creativity, competence, and commitment.'
