Research activities

Research into many topics in the context of circular economy is required to realize a FlexiPlant. We present an overview of our previous and current projects and publications in the areas of adaptive process development, sensor development, automation and digitalization, particle-based separation models, process modelling and optimization, life cycle assessment and design-for-recycling.
