The University of Bayreuth is a research-oriented university with internationally competitive and interdisciplinary research and teaching profiles. The following part-time position (TV-L E13, 75 % of full-time equivalent) is available at the Chair of Ecological Resource Technology at the Faculty for Engineering Science, starting as soon as possible and no later than 1 January 2027: Doctoral Researcher (m/f/d) on Process Simulation for Metal Cycles The Chair for Ecological Resource Technology focuses on the modelling, simulation, and evaluation of global material cycles. Our research focuses on the use and processing of resources from mining to recycling. Our goal is to create sustainable technical systems for metals and mineral resources. We use industrial ecology methods, particularly raw material criticality assessment, material flow analysis, and life-cycle assessment. Thereby, we evaluate environmental and techno-economic aspects. The research group values interdisciplinary collaboration and offers you a variety of opportunities to participate actively. The advertised position is embedded in the ERC Starting Grant project "SEMPATHY" , in which a novel modelling approach of global and sustainable metal cycles is being researched. Closing material cycles is the central challenge to limit the environmental impact of using metals in the technosphere. The technical lifespan of metals between mining and dissipative losses is just 10 years for half of the metals in the periodic table. Whether a metal can be kept in the cycle is determined in metallurgical and recycling processes, whose yields depend on the elemental composition of the feed materials and scraps. This position models those process routes using process simulation , building on a composition hierarchy of elements, materials, components, and products that is being developed in parallel within the project team. It quantifies how process and recycling yields depend on composition and makes that knowledge usable for the optimisation of process routes in the circular economy. The results feed into the Material Pathway Analysis , which the project team develops jointly and with which the material flows of technology metals are modelled and visualised across their entire life cycle. Suitable applications lie in energy technology, electronics, and lightweight construction. Your responsibilities: Identification of the core parameters that determine process and recycling yields of technology metals. Setting up and evaluating process simulations of metallurgical and recycling process chains, considering the elemental composition of feed materials, intermediate products, and scraps. Derivation of composition-dependent equations for transfer coefficients as well as process and recycling yields. Optimisation of process routes for a circular economy of technology metals. Collaboration with the other researchers in the ERC project SEMPATHY. Independent research is needed to reach the project goals. Active participation in the research project, coordination and exchange with research partners. Publication of scientific articles and presentation of results at conferences in English. Writing of project reports.
