Abstract
In the context of the need to transition to sustainable models of production and consumption, the development of a circular economy becomes a key factor in the sustainable growth of small businesses in Kazakhstan. The purpose of the study is to substantiate the conceptual framework and develop proposals for the implementation of circular economy principles in small business management. The methodology is based on the analysis of regulatory and analytical sources, international experience, as well as the use of system and comparative approaches. The research identifies key elements of the circular economy model adapted to the conditions of small businesses in Kazakhstan, reveals barriers and drivers for the implementation of circular practices, and proposes recommendations for their integration into business models. The practical significance of the study lies in the possibility of applying the proposed approaches in developing state policy to support small businesses and in implementing corporate strategies for sustainable development.
