In the field of process engineering we identify that in order to integrate recycling alongside the state-of-the-art battery process, multilevel modeling and control-based modeling will be key players to enable an early detection of scrap and thus enhance resource efficiency. Furthermore, the consideration of recycling under inside a single facility, or at least inside the same company, will lead to more effective recycling, since battery chemistry of own scrap and/or EoL batteries is understood, and resources can be shared between the different steps and machinery.
