    The main stages of the reclamation of solid waste landfills have been considered. The processes that limit ensuring the ecological safety of reclamation have been identified. In particular, three stages that may be hazardous for the environment have been highlighted: leachate treatment, preparation of soil or substrate for biological reclamation, and preparation of seeds and planting material. Leachate treatment by the aeration method in an aerated lagoon is recommended. The prospect of using such a process has been investigated in laboratory conditions. To ensure the prolonged release of nutrients in the reclamation layer, it is suggested to use encapsulated fertilizers. The effectiveness of the encapsulated fertilizer covered with a PET shell has been studied. For afforestation using high-quality planting material, the use of in vitro microcloning technology is proposed. The perspective of the method is shown in the example of microcloning of the white mulberry Morus alba L.

    Modeling and forecasting of the state of the environment in the waste management and management system consumption of Kremenchuk urban territorial community in Wartim

    We consider waste management and management as an area of ​​ecological safety. As a result of the study, the ecological aspects of this branch of activity were analyzed on the example of the operation of the operating MSW landfill in the city of Kremenchuk. The prospective direction of the field of waste management in the region, as well as the state of its financing, are taken into account. Such dangerous factors in the operation of the municipal landfill for the environment as: pollution of groundwater and open dumps of the landfill have been identified. The chemical composition of the leachate formed in the body of the landfill was evaluated and the concentrations of pollutants were compared with the permissible values ​​in wastewater discharged to the city sewer. Priority measures for landfill reclamation were proposed. We analyzed solid household waste landfills from the point of view of resource-energy saving, as an alternative source of energy thanks to the use of generated biogas, as well as extracted secondary resources.

    Acquiring practice in environmental and social impact assessment: case study of Lviv city dumpsite, Ukraine

    Municipal Solid Waste Management (MSWM) is a new and fast-growing business area that is becoming widespread in Ukraine. The fire accident at Lviv city landfill “Hrybovychi” forced the local governments to initiate work on its closure and reclamation. The Environmental Impact Assessment (EIA) of the planned activity is the first mandatory step in this direction. The complex nature of EIA procedures requires a similarly integrated approach to identify hazards and develop a shared vision of existing risks. This is demonstrated by the analysis of two published EIA reports on remediation of “Hrybovychi” dump and the dangers that were not identified. Threats of additional groundwater pollution, causes of fire and consequences of negative impact on adjacent areas, the possibility of re-ignition of the landfill, the spreading of microparticles (PM2,5), and formation of toxic compounds classified as persistent organic pollutants (POPs) together with their long-distance migration – these and other dangers were not identified and were not discussed with public organizations. The article aims at showing a scientific approach to identifying environmental hazards in combination with the social component – assessments of problematic activities for public health, which are often ignored in post-Soviet countries. Current and best practices of the Baltic Sea countries in this field are presented by an international team of university scientists. Analysis of critical observations and making recommendations for preventing, minimizing, and mitigating the adverse effects of an accident can help to improve the peer review and development of similar EIA projects.
