On November 24, 2025, the new Christian Doppler Laboratory for Biodegradation of Water-Soluble Polymers will open at the Centre for Microbiology and Environmental Systems Science at the University of Vienna (CeMESS). Under the lead of Michael Zumstein, the chemical and microbiological processes underlying biological polymer degradation will be investigated. In parallel, scientists at BOKU University, led by Teresa Steininger-Mairinger, are working on the development of polymer- and environment-specific analytical methods. BASF SE is the industrial partner in this interdisciplinary collaboration between experts from the fields of chemistry, microbiology, and environmental sciences. The most important public funding body is the Federal Ministry of Economy, Energy and Tourism (BMWET).

Research for sustainable solutions: Focus on the biodegradation of water-soluble polymers
Water-soluble polymers are important high-performance components in many personal care and household products, with a global annual production of more than one million tons. After these products are used, the water-soluble polymers they contain end up in wastewater, which prevents their recollection and recycling. The sustainable management of these polymers at the end of their life cycle is a major challenge. Biodegradable polymers are of particular interest in this context. "However, our understanding of the biodegradation of water-soluble polymers in the affected environmental systems is still very limited," explains Michael Zumstein, head of the new CD laboratory.
Federal Minister Wolfgang Hattmannsdorfer explains the relevance of the research project: "Research is the key to combining competitiveness and sustainability. The field of polymer research in particular shows how scientific findings can lead to practical solutions. With the new Christian Doppler Laboratory, we are laying the foundation for innovation in Austria that generates added value here as well. This is how we combine economic strength and ecological responsibility – through excellent research and targeted location policy."
Ministry of Economy promotes application-oriented basic research
The aim of the new Christian Doppler Laboratory is to understand the chemical and microbiological processes underlying the biodegradation of water-soluble polymers, thereby creating the urgently needed scientific basis for the development and sound regulation of biodegradable high-performance polymers. The research focuses on key factors influencing degradation, interactions between degradation and the environmental microbiome, and specific chemical analysis methods. Michael Zumstein (laboratory head, CeMESS, University of Vienna), Teresa Steininger-Mairinger (module head, BOKU University), and their research groups are working closely with scientists from the industrial partner BASF SE on these endeavors. "The transformative insights required can only be gained through interdisciplinary and intersectoral collaboration, as practiced in our Christian Doppler Laboratory," Michael Zumstein is convinced.
About Christian Doppler Laboratories
Christian Doppler Laboratories conduct high-level application-oriented basic research, with outstanding scientists collaborating with innovative companies. The Christian Doppler Research Association (CDG) is internationally recognized as a best-practice example for promoting this type of collaboration.
Christian Doppler Laboratories are jointly financed by the public sector and the participating companies. The most important public funding body is the Federal Ministry of Economy, Energy and Tourism (BMWET).
About Michael Zumstein
Michael Zumstein is a biochemist and received his doctorate from ETH Zurich (Switzerland) in 2017. He then worked at Cornell University (USA) and the Swiss Federal Institute of Aquatic Science and Technology (Eawag, Switzerland) on enzymatic processes in wastewater. Since 2021, he has been researching and teaching at the Department of Environmental Geosciences at the Centre for Microbiology and Environmental Systems Science (CeMESS) at the University of Vienna. He is a member of the University of Vienna's Research Network for Environment and Climate and the FWF Cluster of Excellence "Microbiomes Drive Planetary Health."
