    Composting as one of the prospective methods of recycling the organic component of municipal solid waste
    (Видавництво Львівської політехніки, 2020-02-24) Storoshchuk, Ulana; Malovanyy, Myroslav; Tymchuk, Ivan; Lviv Polytechnic National University
    In the conditions of constant deterioration of the environment, municipal solid waste management (MSW) in Ukraine remains one of the most pressing challenges in environmental safety because of its significant accumulation in landfills and the lack of effective mechanisms for its disposal. Approximately 40–50 % of municipal solid waste is organic, so the removal of this part of waste from landfills through composting and conversion of waste into secondary material resources will significantly reduce the environmental load on existing and potentially planned landfills. Therefore, the choice of promising technologies for the disposal of organic waste is one of the major tasks to ensure environmental safety. One of the effective strategies for dealing with excessive amounts of organic waste and one of the best and most affordable technologies for the waste recycling system is composting.

    Analysis of the environmental impact of construction by assessing the carbon footprint of buildings
    (Видавництво Львівської політехніки, 2020-02-24) Shekhorkina, Svitlana; Savytskyi, Mykola; Yurchenko, Yevhenii; Koval, Olena; Prydniprovska State Academy of Civil Engineering and Architecture
    The paper presents a methodology for carbon footprint assessment of buildings according to the current European standard. The analytical formulas are proposed to assess the carbon footprint through emissions calculation for the building life cycle including extraction, transportation, and processing of raw materials, construction and installation process, operation, maintenance, and repair, as well as liquidation and disposal. Beyond the life cycle boundaries, the possible benefits from recycling and reuse of building components and materials are considered.

    International scientific environmental research on sustainable industrial development. The life path of dr. Heinz Leuenberger
    (Видавництво Львівської політехніки, 2020-02-24) Krusir, Galina; Sagdeeva, Olga; Odessa National Academy of Food Technologies
    The article deals with the main scientific priorities of the development of environmental research on sustainable industrial development under the leadership of the international expert in the field of natural resource efficiency and cleaner industrial production, Dr. Heinz Leuenberger, Professor and Senior Advisor at the University of Applied Sciences, Basel (FHNW). Current priorities of his scientific research are green industry, resource efficiency and cleaner production, environmental impact assessments, wastewater, hazardous waste and chemicals management, material flow analysis. Extensive practical research experience and constant work in international projects in the field of environmental protection are aimed at introducing the results into the manufacturing sector of European countries.

    The application of Trindex to predict harmful algal blooms in lake torment (Nova scotia, Canada)
    (Видавництво Львівської політехніки, 2020-02-24) Hushchyna, Kateryna; Bao, Quoc Vo; Tri, Nguyen-Quang; Dalhousie University
    This paper introduces the Threshold Index (hereafter called TRINDEX) for the Harmful Algal Bloom (HAB) prediction in lake Torment (Nova Scotia province, Canada). TRINDEX was suggested via the logarithmic transformation and then the thresholds of bloom pattern were established by the discrimination test named the Receiver Operating Characteristic curve (ROC). The cohort studies will be also presented to show how accurate the bloom prediction when using TRINDEX in comparing to the real observations.

    An investigation of the climate change impacts on the water resources in Iran
    (Видавництво Львівської політехніки, 2020-02-24) Norouzi, Nima; Amirkabir university of technology
    Climate change may be defined as a change in the timing of weather conditions over a period of time. In this paper, relying on IPCC scenarios to investigate the effects of climate change on water resources.

    Waste management problems in the Ternopil region
    (Видавництво Львівської політехніки, 2020-02-24) Struchok, Volodymyr; Ternopil Technical National University named after Ivan Pulyuy
    The National Strategy and the National Waste Management Plan in Ukraine until 2030, the regional program for solid waste management in the Ternopil region for 2018– 2020 on the reality of conducting key infrastructure measures and achieving the desired result for society are studied. An improved version of the solid waste management scheme in the Ternopil region and a suitable scheme for solid waste management in the city of Ternopil within the regional complexes for the municipal waste recovery are proposed and the sources of their financing are substantiated.

    Estimation of daily runoff coefficient of the pervious surfaces for the climate conditions of the city of Lviv
    (Видавництво Львівської політехніки, 2020-02-24) Zhuk, Volodymyr; Vovk, Lesya; Mysak, Pavlo; Lviv Polytechnic National University
    The method of calculation of daily runoff coefficients based on the SCS USDA curve number method is presented in this paper. The calculated values of daily runoff coefficients for climatic and geological conditions of the city of Lviv for maximum daily rainfall events with a return period of 0.1–5 years are obtained.

    Quality level of surface water at the control points of the western bug river (Lviv region)
    (Видавництво Львівської політехніки, 2020-02-24) Odnorih, Zoryana; Manko, Roman; Malovanyy, Myroslav; Soloviy, Christina; Lviv Polytechnic National University; Department of water cadaster and water monitoring Water basin management of the Western Bug and San rivers
    The article analyzes the negative impact of enterprises and public utilities on the surface water quality of the Western Bug River basin (within the Lviv region). The dynamics of changes of indicators of the main pollutants at six control points (2016–2018) and the assessment of surface water quality for 2018 are presented. It is proposed to replace the control units on the Western Bug River and its tributaries in order to obtain more accurate information and improve the work on the basin water management.

    Ecological aspects of alcohol industry enterprises modernization at present stage of development
    (Видавництво Львівської політехніки, 2020-02-24) Havryshko, Marianna; Popovych, Olena; Yaremko, Halyna; Lviv Polytechnic National University
    At the present stage of development, the entire world industry has faced the problem of rational use of renewable natural resources, in particular the most efficient ways of wastewater treatment and the use of accumulated waste in the production process as secondary raw material. In particular, the alcohol industry, as one of the components of food, medical, chemical and various industries, leads to the formation of a huge amount of waste, including wastewater. The food industry, like any other industry, has a negative impact on the environment. Water bodies are the most affected by the food industry. Almost the first place in terms of water consumption per unit of production is the production of alcohol. Consumption of large amounts of water leads to the formation of wastewater, which is highly polluted and adversely affects the environment. Due to the high chemical and biological consumption of oxygen, specific colour and odor, suspended solids, low pH value, the purification of such waste in the filtration fields, and discharge into water bodies is not possible. The purpose of our work is: 1) the analysis of the alcohol industry potential in Ukraine in recent years, and methods of waste disposal as a potential source for the development of bioenergy. 2) environmental aspects of the alcohol industry modernization at the present stage of development and implementation of modern wastewater treatment technologies.

    Ecological state of the rivers in the Zhovkva district of the Lviv region
    (Видавництво Львівської політехніки, 2020-02-24) Golodovska, Olena; Kokhalevych, Kateryna; Stokalyuk, Oleh; Lviv Polytechnic National University; Lviv State University of Life Safety
    Observation of the surface water state is carried out to determine its quality (contaminant content) based on the results of analytical control. The analysis of surface water was made according to the polluting sources of the object. It resulted in the proposed management decisions on directions and measures to improve the state of surface water.
