In economics, new theoretical approaches have often emerged when our traditional paradigms surpassed their limits. Heterodox economic theories have gained increasing attention, responding to shifting contextual factors and challenging traditional, infinite, and unidirectional models of resource use. Since the seminal works of Stahel and Reday (1976), the Circular Economy (CE), has emerged as a central economic concept for a sustainable economic transition in academic and political discussions, gaining significant traction over the past decade. However, much of the outcome of its discussions remains theoretical, with policymakers and institutions often overlooking the fact that successful implementation must occur at the company level. To address this gap, a social empirical research approach was conducted to identify and analyse 18 national and international strategy papers from governmental bodies, industry associations (e.g., Acatech, VDI), and standardization organizations (e.g., DIN). Across over 1,000 pages of documentation, 14 Action Areas for implementing CE principles were condensed. The Action Areas are linked to 55 Operational Implications for industrial implementation, which were further assigned to nine corporate responsibilities to ensure pragmatic and actionable recommendations.
