Given the role of the agricultural sector in the development of the Ukrainian economy, it is important to find methods to improve the efficiency of its operation. Since one of them is the introduction of a circular economy, the study of cases of its application in the country is relevant. The purpose of the study was to show an example of the implementation of this concept in Ukraine, depicting the advantages and disadvantages of its application. The main research methods were analysis, comparison, and forecasting. The most significant example of implementing the principles of circular economics at the enterprise, namely the company Myronivsky Hliboproduct, was evaluated. It was shown that the company's approach is based on processing waste into biogas and using it as energy. This process not only helps to avoid increasing CO2 emissions into the atmosphere, but also makes much more efficient use of the available resources. In addition, the features water recycling and existing trends in this area were described. Special attention was paid to the difficulties that the company faced during the start of the full-scale Russian invasion in 2022, and what actions were taken to improve the situation. Conclusions were also drawn about the likely opportunities for the company to achieve its goals in the context of the circular economy, considering current trends in the development of Ukraine. The practical value of the study lies in its usefulness for developing recommendations for enterprises to implement the concept of a circular economy. In addition, data from the study can be used by state representatives to improve the effectiveness of policy implementation in the agricultural sector
