The circular economy implementation at the European Union level. Past, present and future

Shifting from a traditional linear to an alternative circular paradigm can foster economic growth and support sustainable capital renewal in the European Union. This topic has attracted growing academic interest in recent years. However, the evaluation of case studies regarding Circular Economy implementation, strategies, and practices (at all levels) is still in its infancy. With the aim of bridging this gap, this paper analyses, through a systematic review of case studies, the implementation of circular practices in all economic sectors and industries of the European Union (from 2015 until April 2023). To this end, this research uses a framework of circular strategies built considering the European Union political framework. Based on this analysis, it can be deduced that recycling was the most used circular strategy (24.2%) to reintegrate materials into the economic system and reduce the use of raw materials (18.9%), demonstrating the existence of virtuous circles in the European Union’s economic sectors. The results show that the best performing industry, in terms of circular strategies, is Food and Beverage (17.92%), within the Agri-food economic sector. While the economic sector with the least number of circular strategies (7.86%) is Capital Equipment. This paper proposes several tools for Circular Economy implementation that could lead to future research and support business, policymakers, and the scientific community.
