Used lubricating oils constitute hazardous waste with a high pollution potential, making their organized collection and treatment essential within the framework of the circular economy. This paper examines the management of waste lubricating oils and the institutional and regulatory framework governing their management in the European Union, with a particular focus on Greece. The methodology is based on an extensive literature review of scientific articles, technical studies, and institutional documents, as well as an analysis of European and national legislative provisions related to waste lubricating oils. The institutional framework for waste lubricating oil management in the Greek context is analyzed in depth, along with the role of the collective alternative management system. Greece emerges as a best-practice example at the European level. In 2023, a regeneration rate of 100% of the collected waste lubricating oils was achieved, significantly exceeding the European Union average. These results are attributed to the combination of clear regulatory direction, effective control mechanisms, and the organized operation of the collection and regeneration system. The regeneration of waste lubricating oils represents the environmentally and energetically optimal management option, contributing to the conservation of natural resources, the reduction of emissions, and the implementation of the circular economy. The study highlights the need for continuous strengthening of traceability, monitoring, and quality collection mechanisms in order to ensure the long-term sustainability of the system and the maintenance of high environmental performance in the future
