Unsustainable food supply chains are negatively affecting the environment. As a result, this topic has been debated worldwide, and several actors came to the same conclusions: intervention and actions are a must. Nonetheless, this approach was not standardized, and countries and companies are implementing circular economies differently. This chapter aims to outline the current circular economy approach taken internationally and discuss the barriers of this last. A qualitative analysis was conducted by collecting several case studies and understanding the identified practices and challenges. In the findings, the authors discovered that countries’ policies remain weak globally, though the demand is increasing. Drawbacks and limitations such as economic resources, technological innovation, and incentives are evidenced.
