The circular economy represents an alternative to the traditional linear economy model, which allows the use of resources as long as possible, and the ability to restore and regenerate products and materials at the end of their life. Thus, the circular economy is the main driver of the concept of sustainable development, because this type of economy aims to optimize resource consumption, prevent and reduce resource waste. Methodology. In order to achieve the assumed objective, we proceeded to the following sequence of scientific research methods specific to the socio-human field: monographic analysis, empirical data analysis, studying the experience of foreign states for the implementation of the best practices in the national economy. Scientific results refer to the development of the concept of Sharing platforms. Sharing platforms is a circular business model, which is based on exchanges or joint use of assets or goods. It is of interest to producers who have large and unused production capacities, or a low production utilization rate. This model can be classified into several diversities. (B2B (business to business) - allows potential competitors to collaborate in order to optimize expenses, increase the degree of use of assets, actual efficiency. As an example, the 3D Hubs platform that unites industrial designers with 3D printer owners can serve as a B2B model. Another diversity is the B2C model - business to consumer, as an example we bring the Tool Library case study - a library, which, in fact, does not have any books, instead there is a wide variety of tools and instruments, which can be leased. C2C – consumer to consumer represents a platform for consumers. As an example, the C2C online platform is transport, rental, etc.
