Our ProfileOur Profile

ANTS searches and analyses in research and teaching for solutions and methods to make anthropogenic material flows recyclable. Thus, we aim to develop a raw material management at the product and material level as well as to demonstrate and to implement it by means of practical examples. With its previous expertise, the department is one of the leading research institutions in Europe in the field of mechanical and sensor-based processing technology. The ANTS combines the modelling and evaluation of processing and recycling processes with a view to entire product systems and life cycles in the sense of a circular economy and complements this expertise by technical implementation and demonstration.

Your ProfileYour Profile

We are seeking a motivated student assistant current studying at a university or university of applied sciences to support the FSC² research project focused on the development of a detailed model of different sorting and recycling processes for plastic waste. The project aims to model various sorting and recycling processes considering the composition of the input material, i.e. plastic waste, with regard to its type, quality, and quantity. Based on the modeled material quality, the resulting recyclates will be linked to potential reuse options. The project includes both the development and implementation of suitable modeling approaches as well as the systematic analysis of process and material parameters.

To be successful in this role, you should possess the following:

  • Interest in material cycles and life cycle analysis
  • High motivation and strong communication skills
  • Analytical thinking and attention to detail
  • Interest in plastic recycling and material flow analysis
  • Ability to work independently and willingness to collaborate in a team
  • Good English skills
  • Basic knowledge of material flow analysis, life cycle assessment, and Python is an advantage
