The automotive industry faces challenges because of the electrification of vehicles and the rapidly increasing need for electric vehicle batteries (EVBs). Raw materials availability is limited; however, there will also be a significant number of end-of-life (EOL) batteries. This creates various circular economy (CE) business opportunities for EVB manufacturers, third-party providers, and other stakeholders. However, not all CE solutions are sustainable or economically feasible. In this study, through the use of case studies, expert interviews, and a survey, we determined the current state of the EVB CE in Finland, the possible options for utilizing EOL vehicle batteries, and the greatest barriers for the EVB CE. We found that some EVB-related CE applications are not supported by the government and legislation, for example environmental regulations and building standards. CE opportunities include a shorter lead time for some components, which makes them attractive for EOL applications.
