Carbon-Based Products from Sustainable Materials
Our mission is to produce all carbon-based products sustainably from renewable resources. To achieve this, we integrate advanced process simulation, innovative biorefinery concepts, thermochemical conversion, and cutting-edge biotechnological approaches to redesign carbon value chains from the molecular to the industrial scale. By converting biomass, biogenic residues, and captured CO₂ into fuels, chemicals, materials, and high-value bioproducts, we develop efficient, low-carbon production routes that follow green chemical engineering principles and process intensification strategies. Our research spans catalyst development, multi-omics-driven strain engineering, whole-cell biocatalysis, and circular process design, supported by rigorous modeling, experimental validation, and pilot-scale demonstration. Through this holistic framework, we enable a renewable, circular carbon economy that replaces fossil feedstocks with sustainable alternatives across all applications.

| Abstract | Understanding how materials move through cities, countries and industries is key to creating sustainable systems. We use advanced material flow analysis (MFA) to model and map resource cycles and identify recovery potentials in urban and rural environments. By establishing and linking data on production, consumption, and waste generation, we help decision-makers design circular strategies that reduce losses and increase material efficiency. Our models are based on large-scale recycling experiments. They support evidence-based policymaking, infrastructure planning, and resource management. This systemic approach provides the foundation for a more sustainable metabolism of urban and rural areas in which waste becomes a resource. |
