    Environmentally safe reclamation of solid waste landfills
    (Видавництво Львівської політехніки, 2023-02-28) Grechanik, Ruslan; Malovanyy, Myroslav; Korbut, Mariia; Petrushka, Kateryna; Luchyt, Liubov; Boyko, Ruslan; Synelnikov, Serhiy; Bordun, Ihor; Ministry of Environmental Protection and Natural Resources of Ukraine; Lviv Polytechnic National University; Zhytomyr Polytechnic State University; Armed Forces of Ukraine; Czestochowa University of Technology
    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.

    Obtaining Environmentally Friendly Encapsulated Mineral Fertilizers Using Encapsulated Modified Pet
    (Видавництво Львівської політехніки, 2022-03-01) Grechanik, Ruslan; Lutek, Wojciech; Malovanyy, Myroslav; Nagursky, Oleg; Tymchuk, Ivan; Petrushka, Kateryna; Luchyt, Liubov; Storoshchuk, Uliana; Lviv Regional State Administration; Maria Curie Sklodowska University; Lviv Polytechnic National University
    The article deals with the study of the prospects for the use of mineral fertilizers encapsulated in PET for bioremediation. This increases efficiency, prevents environmental pollution from undigested plants with plant nutrients, and minimizes the number of application operations. In addition, it disposes of a significant portion of PET waste, the uncontrolled accumulation of which poses a threat to the environment. The basic technological schemes of preparation of a film-forming composition and encapsulation of fertilizers are offered. The kinetic parameters of the process of release of batteries of granulated ammonium nitrate encapsulated with a film based on modified PET are determined.
