The implementation of circular business models becomes imperative under the conditions of the energy crisis that appeared at the European level this year. Governments and the business environment are required to look for urgent solutions for the transition to an economy based on alternative energy resources. In this context, taking over successful practices and sharing experience become the fastest methods to adopt circular business models. The purpose of this study was to analyze the experience of other states in the development of successful circular businesses and to identify the possibilities of implementing these practices in the Republic of Moldova. The research analyzed the activity of nine companies from four countries that operate based on circular models, in particular - the Circular Suppliers business model. At the same time, companies from the Republic of Moldova that develop businesses based on renewable, biodegradable or recyclable resources were identified and analyzed. The analyzes allowed establishing the opportunities and challenges existing at the national level in order to carry out a circular business. The areas where the principle of circularity can be implemented in the Republic of Moldova were identified and the resources that can be used in the most efficient way were determined.
