Battery recycling is a challenging process and urgent development is needed in Europe to scale up technology to meet the recycled content demands stipulated by regulation. Shredding to battery black mass is becoming more common, but to be commercially viable need to be operating at large scale eg >70kT per year. These processes are highly optimised and automated at scale. Most black mass is sent to Asia for processing back to metal precursors. Development of European technology at scale is critical to provide security through urban mining and support a growing battery supply chain. How do you get to this scale? First of all, you need to find the right process to scale up. CPI excel in automation of battery processes to accelerate R&D, by using lessons from automation in production to enhance the development of early stage processes. This talk will describe development of processes in recycling with a variety of materials and alternative extraction techniques such as deep eutectic solvents. Aspects of projects at CPI in battery and WEEE waste recycling will be described, to recover metals from cathode materials, mine tailings and circuit waste, using automation and small pilot facilities to demonstrate effectiveness of the technology. Lessons from the automation process that can be utilised by anyone will be described.
