    Study of the properties of anp fertilizer encapsulated with the use of modified waste of pet
    (Видавництво Львівської політехніки, 2020-02-10) Nahurskyy, Oleh; Malovanyy, Myroslav; Synelnikov, Serhiy; Tymchuk, Ivan; Krylova, Galyna; Lviv Polytechnic National University
    The experimental investigation of the solubility of the prolonged-action nitroamophos obtained with the use of modified polyethylene terephthalate (PET) waste is presented. The kinetic coefficients of the diffusion process of the substances inside the shell are determined. The possibility of applying a theoretical model to predict the agro-ecological properties of encapsulated ammonium nitrate phosphate is demonstrated.

    Environmental and resource evaluation of smelter slag
    (Видавництво Львівської політехніки, 2020-02-10) Malovanyy, Myroslav; Ilyash, Oksana; Povzun, Oleksiy; Stepanets, Oleg; Serga, Tatiana; Gubar, Oksana; Serdyuk, Volodymyr; Lviv Polytechnic National University; Donetsk National Technical University
    The gross emission of harmful substances (dust) while unloading the smelter slag of PJSC “Mariupol Iron and Steel Works” into the waste heaps from the dump truck body and during their storage was calculated. The expediency of restoration of blast furnace slag as a siliceous component in cellular concrete was proved. The optimal compositions of cellular concrete mixtures (including the addition of TLS plasticizer – technical lignosulfonate) were determined based on the following criteria: average density of cellular concrete in the dry state and its compressive strength.
