With the rapid development of the electric vehicle (EV) industry, the large-scale retirement of batteries poses significant environmental risks and challenges to industrial sustainability. Circular business models based on the 10R circular strategies offer a promising solution. However, their successful implementation largely depends on policies and regulations, which serve as th ecore enabling factor. This study combines a review of regulatory frameworks with semi-structured interviews in the Swedish EV battery ecosystem to explore the interrelated pillars and policy pathways shaping the implementation of the 10R strategies under the Battery Regulation. The analysis identifies four interrelated pillars: policies and regulations, digital technologies, business models and economics, and organizational and behavioral management. These pillars demonstrate how different dimensions intersect to influence the adoption of 10R strategies for EV batteries. The study contributes to both theory and practice by proposing a conceptual policy pathway for translating the 10Rs into actionable strategies. It provides guidance for policymakers and industry actors in building a digitally enabled, regulation-supported, and standardized circular battery ecosystem.
