Advanced Separation and Environmental Management of Urban and Mining Wastes

Dear Colleagues,

Increasingly, it is recognized that the proper utilization of urban and mining residues represents a key strategy for promoting environmental sustainability and the efficient use of natural resources. Traditionally, large volumes of waste are stored in tailings dams and/or disposed of in ways that may pose risks to society, typically occupying extensive areas and representing significant environmental hazards. When these materials are reused; for example, in cement production, civil construction, or the recovery of remaining metals, risks to society are reduced, while clear contributions are made to environmental preservation.

The reuse of these materials also contributes to energy conservation and the preservation of mineral resources. The extraction, transportation, and processing of ores require substantial amounts of energy. By reusing already available residues, the intensity of these production stages can be reduced, resulting in lower energy consumption and decreased generation of hazardous effluents.

Furthermore, the reuse of wastes helps minimize environmental impacts such as soil and water contamination and the degradation of natural landscapes. By integrating these materials into new production cycles, the concept of a circular economy is promoted, in which materials previously considered waste acquire new economic and environmental value.

Therefore, the efficient utilization of mining residues represents an important approach to balancing economic development, energy conservation, and environmental protection. In this context, the topic editors encourage researchers to share interdisciplinary research and perspectives on the treatment and utilization of urban and/or mining wastes.
