Circular procurement: A systematic literature review

In recent years, there has been a phenomenal growth in procurement research towards a circular economy (CE). However, to date, there is a lack of systematic synthesis of this body of knowledge hindering theoretical development. This work aims to investigate the current state of circular procurement (CP) in both the public and private sectors through a systematic literature review. To this end, this paper reviews the relevant studies published between 1998 and 2021 and identifies three themes: antecedents, practices, and performance (outcomes). New subcategories for the themes are also presented. Based on the structured analysis, we propose a conceptual theoretical model of CP and future research directions.
