The increase in the amount of waste due to industrial growth and the potentially harmful impact of waste on the environment require a comprehensive approach aligned with the principles of sustainable development, which not only aims to preserve natural resources but also to encourage innovation in a sustainable direction. The main idea of this project is to propose an innovative, dual solution for selected waste streams in the Republic of Serbia: on the one hand, they can be a resource for the return/extraction of strategic elements, and on the other hand, adsorbents for the removal of selected organic and inorganic pollutants from wastewater.This approach is directed towards a circular economy, with the intention of establishing a sustainable use of waste.
