    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.

    Prospects of using PET waste for environmentally friendly mineral fertilizers
    (Publishing House of Lviv Polytechnic National University, 2016) Nagurskyy, Oleg; Malovanyy, Myroslav; Synelnikov, Sergij; Vahchuk, Viktorija
    The article presents the technological possibility of using PET wastes for encapsulation of granulated mineral fertilizers. The schematic flowsheet is proposed to obtain film-forming composition. An encapsulated ammonium nitrate with predictable kinetics of fertilizer components release was obtained.
