The project focuses on supporting the transition of companies to the circular economy (CE). The aim is to create innovative models to help companies implement circular principles. This transition from the traditional linear model, which operates on a make-use-dispose principle, towards a circular model, where materials and resources are reused, has the potential to address global environmental issues such as climate change, biodiversity loss, and resource scarcity. The project results are expected to provide new insights into how companies implement circularity principles, what barriers they are overcoming in doing so, and what economic and non-economic effects result. The project's findings will support the design of public policies aimed at increasing resource efficiency, reducing dependence on primary raw materials, and improving the competitiveness of firms and entire economies. The project outputs will be published in reputable scientific journals, and the results will be disseminated through conferences and collaboration with international institutions.
