Model-based control systems considering both battery production and recycling as consequence of production are currently scarcely addressed in research. Making the link from recycling back to production can provide helpful insight of the interrelations between both process chains adding more complexity to the overall system but also including decisions that have to be made in when passing material between the process chains . An example would be exclusion of highly contaminated material that cannot be handled by an in-house recycling route. Scenarios like these can be very facility-dependent and individual but are necessary to be considered long-term due to the growing importance of a high secondary materials share driven by demand and politics. Additionally, the concept of circulation factories combines both process chains under one roof offering the advantage of independence from recyclers, while also providing rejected parts of known chemistry for recycling. The extension of control systems to include recycling is therefore favorable since the material passed on between the process chains highly influences the product quality, especially considering the imperfect or unknown process quality of the recycling processes.
