Circular Economy Approach to the Management of Used Cooking Oil for Biofuel Production

Abstract

• The management of used cooking oil (UCO) in the framework of a circular economy presents numerous environmental and economic benefits. This study aims to explore how the implementation of circular economy principles can enhance UCO management for biofuel production.. Methods: The research adopts a mixed-method approach, combining a literature review with empirical data analysis to examine the involvement of key stakeholders, such as households, waste banks, collectors, and biofuel producers. Results: Findings reveal that UCO management not only reduces environmental pollution through waste minimization but also creates economic opportunities across the supply chain. The study highlights the transformation of UCO from waste to a valuable resource, aligning with the concepts of reduction, reuse, recycling, refurbishing, and renewal. Further, policy support, public awareness, and technological innovation are identified as critical factors for effective UCO management. Conclusions suggest that the integration of circular economy practices in UCO management facilitates the transition to renewable energy sources, contributes to carbon emission reductions, and promotes sustainable economic growth. Implications: This research emphasizes the importance of multi-stakeholder collaboration, regulatory frameworks, and continuous evaluation to optimize UCO's role in achieving broader sustainability objectives.
