Restoration of the ecosystem of the Yavoriv State Mining and Chemical Enterprise "Sirka" tailings storage facility

The article addresses the problem of ecosystem restoration of the Yavoriv Mining and Chemical Enterprise "Sirka" tailings storage facility, which is one of the largest sources of anthropogenic environmental impact in western Ukraine.The work highlights the main environmental risks associated with the presence of sulfide waste, which causes the formation of acid drainage and migration of heavy metals into the soil-water environment.A comprehensive approach to land reclamation was proposed, including geotechnical preparation, formation of a fertile layer, use of microbial inoculants, sowing of pioneer grasses, and phased planting of tree species.Special attention was paid to the selection of phytoremediation plants capable of soil stabilization and reduction of toxicant content.The results of pilot work were presented, which confirmed the effectiveness of combining engineering and biological methods in forming sustainable plant communities and reducing environmental risks.It was proven that successful ecosystem restoration depends on adapting technologies to local conditions, applying systematic monitoring, and regulatory support.The obtained results can be used as a model for developing longterm reclamation strategies for other technogenically disturbed territories.
