Circular economy is a system that minimizes the generation of waste and ensures that materials and resources are returned to the product cycle at the end of their life cycle, thus aiming to preserve the value of products for a long time. While interest in the "Circular Economy" is increasing in our country and in the world, studies investigating the extent to which the concept is adopted by businesses are quite limited. In this study, in order to contribute to filling this gap in the literature, a systematic review of the sustainability reports of enterprises listed on Borsa Istanbul was conducted to determine how enterprises incorporate the circular economy concept into their sustainability agenda. The study reveals (i) the level of disclosure of circular economy, (ii) the relationship between circular economy and sustainability, and (iii) the circular economy practices presented. The results of the analysis show that circular economy has started to be integrated into the sustainability agenda by companies.
