Документ Design and research of eco-friendly coffee grounds filled polymer composites(Національний університет цивільного захисту України, 2020) Lebedev, V. V.; Tykhomyrova, Tetiana Sergiivna; Lozovytskyi, A.; Grigorova, T.; Litvinenko, Ie.; Avina, S. I.; Saimbetova, Zh.Документ Design and Research of Environmentally Friendly Polymeric Materials Modificated by Derivatives of Coal(VÚRUP, 2023) Lebedev, Vladimir Vladimirovich; Miroshnichenko, Denis Viktorovich; Tykhomyrova, Tetiana Sergiivna; Kariev, Artem; Zinchenko, Mariya; Bukatenko, Nataliia; Filenko, OlesiaThe aim of the given work was to design new ecologically friendly polymer materials modified by derivatives of coal. An overview of the current trend in the development, production and application of efficient nvironmentally friendly polymer materials and composites is given. The main ways of hybrid modification of environmentally friendly polymeric composite for obtaining effective products based on them are presented. It is shown that it is promising to obtain environmentally friendly polymeric materials based on coffee waste using hybrid modifiers in the form of humic substances. Optimization studies have been conducted to determine the most effective composition of new environmentally friendly polymeric materials based on bioplastics "OK compost HOME" and coffee waste modified with humic substances. It was found that filling the bioplastic "OK compost HOME" with such coffee waste as coffee husk is more effective as with coffee grounds. It was found that the optimal content is 60 % mass coffee husk, that was modified by humic substances (2 % mass).Документ Environmental management implementation in wastewater treatment at a machine-building enterprise: from theory to practice(EDP Sciences, 2023) Bosiuk, Alona; Filenko, Olesya; Shkop, Andrii; Kulinicn, Serhii; Tykhomyrova, Tetiana Sergiivna; Shestopalov, OleksiiThis study examines environmental management implementation in the context of wastewater treatment at machine-building enterprises. The article aims to assess how effectively environmental management is used in the wastewater treatment system to ensure rational resource use. It is noted that wastewater contains a significant amount of various pollutants that must be removed before disposal. A wastewater samples analysis was carried out to assess the environmental management implementation's effectiveness. The changes in the concentration of the pollutants during three months were found: the hydrogen indicator decreased from 7.83 mg/dm3 to 7.58 mg/dm3. The oil product concentration increased from 22.2 mg/dm3 to 3.4 mg/dm3, while the fat concentration remained stable. The received results provide important information for improving the wastewater treatment system and environmental management implementation. To ensure environmental safety and compliance with environmental standards, it is necessary to implement environmental management in wastewater treatment at machine-building enterprises. The optimal wastewater treatment technology choice and monitoring program development are described. The article contains practical recommendations for the implementation of environmental management at a machine-building enterprise and aperspective on this direction of development. The research is relevant and useful for machine-building complexes that have problems with wastewater treatment and aim to implement environmental management.Документ Sorption characteristics studies of eco-friendly polymer composites(EDP Sciences, 2021) Lebedev, Vladimir; Tykhomyrova, Tetiana Sergiivna; Lytvynenko, Oleksandr; Grekova, Alla; Avina, SvitlanaThis paper presents the results of new composite materials based on polylactide and coffee grounds sorption characteristics study. New material, that include coffee grounds as additive material is cheaper than one of common polylactide. All types of dishes cam be made from new material and they also will be biodegradable, as made from polylactide. The sorption properties and characteristics were tested in different liquid medium. The last was chosen among the most wide spread mediums which are contact with dishes during its operational life. It was found, that optimal content of coffee grounds is 40 wt.% as for level of impact strength also for complex of sorption characteristics
