Modern socio-economic development faces critical global challenges, among which climate change, depletion of natural resources, ecosystem degradation, and increasing volumes of waste play a leading role. In this context, the inefficiency of the traditional linear economic model – based on single-use resource consumption and waste accumulation – has become increasingly evident. A response to these challenges is the transition to a circular economy, an innovative model focused on preserving material value and enabling their repeated use within closed-loop systems. This approach minimizes resource loss, reduces environmental pressure, and contributes to the development of more resilient supply chains. In the era of digitalization, digital platforms are beginning to play a pivotal role in implementing circular economy principles. They facilitate the optimization of exchange, repair, reuse, rental, and resale of goods – particularly in resource-intensive sectors such as the textile and electronics industries. Digital tools enhance transparency, enable efficient coordination among market participants, support data integration, and foster the emergence of new consumption models. This article explores the potential of digital platforms as a foundational infrastructure for scaling the circular economy and shaping a sustainable development model on a global scale.
