    Obtaining and Using Substrates with Sewage Sludge
    (Видавництво Львівської політехніки, 2022-03-01) Malovanyy, Myroslav; Storoshchuk, Uliana; Lviv Polytechnic National University
    The article is devoted to the study of the prospects of using compost with sewage sludge in the raw material for the recultivation of disturbed lands. A special installation was used for bio-composting, which allowed controlling of the process parameters. The results of bio-indication of composts obtained under different conditions of compositions of the raw material mixture are given. Based on the analysis of the results of bioindication, the optimal composition of the raw material mixture using “fresh” and “old” sewage sludge is established. An analysis of the parameters of the bio-indication process was carried out for this compost of optimal composition, which makes it possible to develop recommendations for the implementation of the process in industrial conditions.

    Cleaning of Gas Emissions By Biological Method
    (Видавництво Львівської політехніки, 2022-03-01) Dyachok, Vasyl; Venher, Liubov; Huhlych, Serhiy; Svjantko, Iryna; Lviv Polytechnic National University
    The paper shows the possibility of using chlorophyllsynthesizing microalgae of Chlorella Vulgaris to purify biogas from carbon dioxide (CO2), hydrogen sulfide (H2S) and ammonia (NH3). Experimental dependences of the dynamics of CO2 uptake by microalgae under the action of H2S inhibitor and NH3 activator are presented. A mathematical description of the growth of biomass of microalgae Chlorella Vulgaris depending on the concentration of hydrogen sulfide and ammonia was obtained. The optimal values of hydrogen sulfide and ammonia concentration for the efficient process of carbon dioxide uptake by chlorophyll-synthesizing microalgae Chlorella Vulgaris from biomethanization gas have been established.

    Strategic Environmental Assessment – Underestimated Tool for Sustainable Subsoil Use
    (Видавництво Львівської політехніки, 2022-03-01) Karabyn, Vasyl; Shuryhin, Vladyslav; Shutiak, Sofia; Chmiel, Marek; Kulhánek, Rastislav; Lviv State University of Life Safety; Ukrainian National Bar Association; Politechnika Częstochowska; Comenius University Bratislava
    Strategic environmental assessment is an effective tool for improving the level of environmental safety in various areas. The purpose of the article is to identify and classify the main tasks of strategic environmental assessment in subsoil use, taking into account its role and functions in the subsoil management system, and to suggest ways to improve environmental safety in subsoil use by means of strategic environmental assessment. The materials for the article were the results of many years of authors' research on various aspects of the methodology for assessing the environmental safety of subsoil use and scientific source analysis. The main research methods were comparison, deduction, analysis, synthesis, and classification. The authors grouped the tools of the strategic environmental assessment into five main groups: analytical, organisational, scientific and technical, control and procedural, and media. Analysis of the legal framework determines the need to finalise the draft of the Subsoil Code to take into account the requirements of the Law of Ukraine “On Strategic Environmental Assessment” in the context of carrying out state examination and assessment of reserves and resources of minerals and establishing conditions for mineral raw materials, drafting industrial development (technological scheme) of the deposit. The classification of the tools of strategic environmental assessment in subsoil use is carried out. Analysis of draft legislation in the field of subsoil use shows positive changes in achieving sustainable development goals. Simultaneously, the authors identified some inconsistencies between different legislative acts and projects.

    The Influence of the Organization of Society on the State of the Environment
    (Видавництво Львівської політехніки, 2022-03-01) Mykhaylenko, Volodymyr; Antonov, Oleksiy; A. M. Pidgorny Institute of Mechanical Engineering Problems of NAS of Ukraine
    The article is aimed at researching the current problem of socioecology – the causes and consequences of possible resource depletion, as well as establishing the possibility of its averting. There are two classifications of natural resources from the point of view of ecology: according to their renewability and according to the possibility of use. Based on the concept of the Rouche limit, the law of the resource balance of society is formulated, which relates the social productivity of labor to the population density and the depletion of available natural resources. This law is another form of recording the balance of social production and consumption of resources. The consequences of its violation are shown.The effect of abiotic, biotic and anthropogenic factors on the rate of depletion of available natural resources is studied, and the decisive role of scientific and technological progress in the development of the resource base of society is shown. It was determined that scientific and technological progress is a decisive factor in averting a resource catastrophe by humanity and individual nations. The conducted study of the social structure allows us to draw a conclusion about the decisive role of industrial relations in the implementation of new scientific and technical solutions in production.
