The objectives of this master thesis are the implementation of a simulation software, the subsequent development of a process model and a simulation framework. This should simplify the roll-out and implementation of the in-house recycling plant for copper and hydrochloric acid in other AT&S plants. Extensive literature research introduces the topics of copper as a raw material, industrial wastewater and wastewater treatment. Moreover, the AT&S in-house recycling plant is also explained in detail, which is then modeled. The theory of process modeling and simulation is also briefly discussed. The practical part starts with the definition of requirements, the selection of the software and following implementation of ITHACA. By collecting process data from the existing recycling plant in AT&S Hinterberg (Austria), a model and a simulation framework can be created to complement future tests of the applicability of the recycling concept. The model development, validation, verification and creation of a simulation framework are also documented.
