Accumulation of leachate at municipal solid waste (MSW) landfills is a significant environmental problem. The analysis of known technologies of leachate treatment was performed. It was established that it is not effective to use the same technology to treat leachate in two different periods: before the landfill closure and reclamation process as well as afterwards. The application of integrated two-stage aerobic-reagent pre-treatment technology with subsequent full treatment at municipal wastewater treatment plants was proposed for these purposes. The results of laboratory studies of optimal parameters of technology realization for the pre-treatment of Lviv MSW landfill leachate were presented. Recommendations for the practical implementation of the combined two-stage aerobic-reagent technology for the landfill leachate pre-treatment were developed.

Monitoring studies were carried out on the territory of the Lviv wastewater treatment plants. The volumes of accumulated stocks of the sludge site were determined, its qualitative and quantitative indicators were identified, and the presence of limiting factors was established. Based on the obtained data, 2-D models characterizing the vertical and horizontal accumulation of elements were created. Bioindication studies were conducted to determine the feasibility of using sewage sludge as a growth substrate. Modeling was performed to determine the potential area of reclaimed land

The paper presents the results of research to assess the degree of transformation of forest ecosystems in the area of influence of the Zhytomyr landfill (Ukraine) - one of the typical Ukrainian landfills, which is operated with minimal implementation of environmental protection measures. The study was conducted to identify the relationship between the condition of plantations and the functioning of municipal solid waste landfills. In the study of the estimation of the transformation degree of forest ecosystems in the area of influence of the municipal solid waste landfill in Zhytomyr, it was established that in the studied areas there was a decrease in bonitet by I-II classes, completeness by 0.1-0.2 units, growth by 13-35% in comparison with background values. On the basis of the research of the condition of pine plantations by categories of vital activity of trees the integral indicator was calculated – the index of the condition of forest stands, which characterizes the degree of their damage in the event of aerial pollution of soil and groundwater. It was determined that the maximum values of the index of forest stands condition were observed in the area closest to the landfill (2.88 units), ie, these are severely weakened stands, the minimum in the control (1.28). Based on the results of the studies, it was established that Scots pine is a convenient and acceptable bioindicator for assessing the state of the environment in the area of influence of municipal landfills provided that its distribution is uniform on the territory and it is available for research. The sanitary condition of pine plantations deteriorates with the approach to the source of pollution. According to the established indices of the condition of pine plantations, a regression analysis was performed and a mathematical dependence was determined, which most accurately describes the change of these indicators with the distance from the landfill boundary. The approach used for bioindication studies of conifers can be recommended for implementation in practice as a method for assessing the transformation of the environment in the area of influence of municipal solid waste landfills.

The paper presents the results of research on the implementation of monitoring of the landfills influence on the atmospheric air using bioindication methods on the example of the Zhytomyr landfill (Ukraine) - one of the typical Ukrainian landfills, which is operated with minimal environmental protection measures. A comprehensive study of atmospheric air pollution in the landfill area was carried out using a human sensor system and an integral assessment using bioindication (lichens were chosen as bioindicators). The study revealed a reliable exponential dependence for modeling the relationship between the distance from the source of gas formation (solid waste landfill in the city of Zhytomyr) and the intensity of odor. The level of atmospheric air pollution was also determined based on the assessment of the projective coverage of the tree trunk with lichens. The research revealed an exponential dependence for modeling the relationship between the distance from the landfill boundary and the total coverage of the tree trunk with lichens. The results of the analysis confirmed the correctness of the use of the aforementioned method. The relationship between the results obtained by the lichen indication method and the strength of the odor from the landfill was evaluated. Based on the results of calculating the relative values of the assessment of atmospheric air pollution by the method of coverage of the tree trunk with lichens and the strength of the odor, a regression analysis was carried out and mathematical relationships were determined, that most accurately describe the change in these indicators with distance from the landfill boundary. It is proved that both tested methods can be used in Ukrainian realities to monitor the state of atmospheric air in the area of influence of municipal landfills, depending on the purpose of research. The analysis of the research results confirmed the significance of the results of the obtained assessment of the impact of the Zhytomyr solid waste landfill on the state of atmospheric air. The materials of these studies can find further application for the formation of databases of knowledge of landfills, which will allow to develop a strategy for managing them as an object of increased environmental hazard.

An impact of poultry farms on the environment caused by ammonia emission from chicken manure has been studied. A negative impact minimisation method by adding natural sorbents to the bedding composition has been proposed. The optimum natural adsorbents compositions (clinoptilolite and palygorskite) for adding to the bedding as well as the optimum mixture ratio of these adsorbents to chicken manure mass have been determined. The optimum conditions for obtaining granulated organic-mineral fertiliser of prolonged action based on this composition have been studied. In the result of the research data analysis a technological scheme for organic-mineral fertiliser production based on chicken manure and a mixture of natural adsorbents have been proposed.

The study of the composting process is a very urgent task. The rapid growth in food production leads to the formation of waste, which should be safely disposed of in a natural way – composting. Composting the vegetable component of food waste can significantly reduce the proportion of waste falling into landfills and utilize the food waste from the hotel and restaurant industry. Additional enrichment of the compost mixture of food waste with the «Baikal EM» microbiological additive accelerates the maturation process and enhances the efficiency of the finished compost. Such compost does not contain viable weed seeds or pathogenic microflora and can be used as a fertilizer. In contrast to the control, a sufficient level of germination index is observed for the studied samples and they are not phytotoxic. The finished compost can be used as a fertilizer in agriculture for growing crops. The results obtained indicate that the index of germination of radish seeds increases along with the duration of fermentation of the composted mixture. Communities of microorganisms contained in the «Baikal EM» additive accelerate the natural process of composting, taking an active part in the destruction of the components of the vegetable mixture. The pH value of the finished compost, both under thermophilic and mesophilic conditions, is close to neutral indicators. High values of CO2 emissions from reactors were recorded in the second week under thermophilic and for 3 weeks under mesophilic conditions. The finished compost that fermented under thermophilic and mesophilic conditions can be used as fertilizer, but considering that additional energy is required to create thermophilic conditions, it is advisable to compost the food waste mixture with the addition of the microbiological additive «Baikal EM» under mesophilic conditions.

The prospects of using sewage sludge from Lviv wastewater treatment plants for biological reclamation have been assessed.

The study, using a survey, found social attitudes towards the separate collection and problematic issues that may hinder its implementation. It was found that most respondents are not familiar with the possibilities of waste composting at home, and residents of multi-storey buildings generally consider composting at home in the kitchen inexpedient. The paper identified the causes of ignorance of the population on household composting conditions. The paper presents the scientific results of the popularization of composting with microbiological additives at home among the population. The study aimed to develop a practical, effective model for the management of the bioorganic component of municipal solid waste, which minimizes the impact of waste on the environment and maximizes resource potential by organizing composting organic waste at home. Based on the research data, recommendations for the population of Zhytomyr on composting household waste have been developed. They explain in detail the mechanism of composting at home and outline the benefits of such composting. The obtained results are practical, they can be used for explanatory work among the population and the development of recommendations on separate waste collecting and composting of the organic part of household waste in domestic conditions.

The purpose of the research was to rise the level of environmental safety in the coal mining regions by using combustion metamorphic rocks of the spoil banks, which were reinforced with the modified wastes of the polymer production, namely carbonous binders, as a man-made raw material for the base courses of roads. The environmentally friendly technology of the construction of the base course of roads from layers of combustion metamorphic rock mixtures (CMRM) with different largest granule size of crushed stone has been developed. The bulk density and compressive strength in a cylinder on a hydraulic press were used as the criteria for determining the rational granulometric composition. The practicability of reinforcing combustion metamorphic rocks with coal tar, which is a modified waste of the polystyrene production - polystyrene dust has been shown. The technology of preparation of the tar and polystyrene binder (TPB) has been developed. The optimal concentration of polystyrene dust in the organic binder of the coke production and the time of their combination (as the optimal areas of admissible values of variation factors X1, X2, X3) were determined using the method of mathematical planning of the three-factor experiment (5 optimization parameters). The coefficients of the regression equations have been calculated using the least squares method. Regression equations are a second-degree polynomial. The three-dimensional diagrams "parameters of system optimization - variance factors" have been calculated and drawn. In accordance with the obtained regression equations, the response surface has been designed in a three-dimensional space. The areas of admissible values of optimal variance factors correspond to the limit values of the response functions.

The research of physical and chemical properties of landfill leachates and migration of its hazardous components into hydrosphere and biosphere is a current problem in the global context. The object of the research is landscape-changing factors of the Lviv municipal landfill (Ukraine). It was defined that the biggest part of oil products accumulates in the leachates at the south-western side of the landfill (23.6 mg/dm3) and it is 2.36 times higher than the value of the maximum permissible concentration (MPC) (10 mg/ dm3); the most salted leachates with chlorides and sulfites are those accumulating at the foot and at the northwestern side; phosphates content of the investigated samples of the leachates was the highest at the foot of the landfill and it was 12.8 mg/dm3, which exceeds the MPC (10 mg/dm3) by 1.28 times; high concentration of ammonium nitride was discovered in the leachates at the foot (76.1 mg/dm3) and at the northwestern side (46.3 mg/dm3), which exceeds the MPC (30 mg/dm3) by 2.53 and 1.54 times, accordingly; the highest indicators of total iron are typical for basins nearby (at the foot - 68.2 mg/dm3, at the northwestern side – 56.3 mg/dm3) and exceed the MPC norms (2.5 mg/dm3) by 27.28 and 22.52 times, respectively. According to certain indicators, the content of hazardous components in the leachates, which accumulate at the foot and at the northwestern side, exceeds the MPC and is several times higher than in the natural basins at the distance of 800 and 1200 m.

Waste (tailings) of mining and processing plants of Kryvbas were studied by the stages of their magnetic enrichment. The granulometric compositions of the tailings, the amount of iron (total and magnetic) and the mass fraction of solid in them are determined. The expediency of disposing of ferruginous quartzite waste at the first stage of enrichment as a silica component in cellular concretes is proved. Optimal compositions of aerated concrete mixtures are determined based on the following criteria: the average density of cellular concrete in the dry state and its compressive strength.

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.

We studied ways of ensuring of the environmental safety of recreational territories of a mountain ecosystem on the example of "Vizhnytsky" National Nature Park (NNP) in the Pokutsko-Bukovynian Carpathians. Existing approaches to ensuring of the environmental security of nature reserve objects have been analyzed. The characteristic of the study region has been given. We proposed the concept for ensuring of the environmental safety of recreational areas. Its base is analysis of components and identification of components, improvement of which would ensure the appropriate level of environmental safety of NPP. An algorithm has been constructed for theoretical and experimental studies for assessment of the sanitary-microbiological state of the atmosphere, hydrosphere and soils in the study area and their influence on the environmental safety of NPP. We monitored sanitary-microbiological and sanitary-environmental indicators of the hydrosphere, atmosphere and soil and identified environmental threats to analyze the state of recreational territories of the mountain ecosystem. It is proposed to plan measures for intensification of biological natural processes of self-purification of surface water in the area of recreation territories to ensure preservation of the limited values of sanitary-microbiological and sanitary-environmental indicators of the hydrosphere. The results of atmospheric air monitoring in the area of the recreation territories indicated that the air ion content was 2.4 times higher, and the total microbial number was 1.5 times lower than in the territory of traditional farming. Therefore, the atmosphere of the recreation area does not require any technical measures to improve it. A system of engineering measures has been proposed for stabilization of environmental safety in the area of recreational territories (using the "Viya" fibrous carrier) for intensification of purification of surface water and disposal of wood waste by biofuel production. Implementation of the proposed measures would help achieve stabilization of the environmental safety of the recreational territories of the mountain ecosystem

The paper analyzes the advanced technologies of wastewater treatment with a high content of organic pollutants and ammonium ions. Two different bi-stage scenarios for the treatment of such effluents are proposed. The first scenario includes the pretreatment in aerated lagoons and the final stage at the wastewater treatment plants after appropriate dilution with municipal sewages. The second scenario also includes the first stage in aerated lagoons with a tertiary treatment at the plant for cyanobacteria cultivation with the use of obtained biomass for biofuels production. The effects of the aeration periodicity on the leachate treatment efficiency and also on the composition of microbiocenosis in the aerated lagoons were investigated. Leachates of the Lviv landfill of municipal solid waste (MSW) were used in experimental investigations. Lviv landfill of MSW was used for domestic and industrial wastes deposition for almost six decades, since the 1960's. It was found that the highest effect of ammoniacal nitrogen removal was obtained in the mode of periodic aeration, with the cycle duration of two hours including the one-hour aeration. It is found that microorganisms extracted from the leachates of the Lviv MSW landfill are prospective for the new biotechnologies of treatment of the highly concentrated wastewaters, since this microbiocenosis is resistant to the widespread pollutants, in particular to heavy metal ions.

The estimation of ecological danger from uncontrolled accumulation of wood waste in the Pokutsko-Bukovynian Carpathians is given. Specific natural features of the region of research that determine the level of their environmental safety are described. Objects of research are wood residues. Subject of the work is study of conditions for wood residues recycling using wood-pellets production by extrusion method. Authors compare main methods of wood residues granulation used in Ukraine and in foreign countries. Drying of wood residues in a stationary layer is proposed to improve the granulation process. For this purpose, influence of thermal agent's speed, its temperature, thickness of the layer on the process of wood residues drying is studied. Authors find out that increasing of temperature leads to rising of heat losses to the environment as well as to overheating of material upper layers. Optimal conditions for wood residues drying are established to minimize the energy consumption and drying duration. Optimal thickness of the stationary layer of wood residues is 20·10-3 m and optimal temperature of thermal agent is 100 °С. Authors show the benefit of natural lignin-containing compounds usage for the formation of wood pellets. Furthermore, it is found that an increase in the concentration of the binding agent leads to a deterioration of the bonding of wood particles between them, which causes a decrease in their static strength. Technological improvement of equipment for mixing of components in the process of wood pellets obtaining is offered. Equipping the conical part of the casing with a drainage hole ensures the removal of the excess of the binder component, which leads to a reduction in the fragility of wood-pellets. As a result, the optimal correlation between the amount of wood waste and the binder is determined. A framework flow chart is proposed for production of wood-pellet from wood residues using extrusion method. Usage of proposed technological approach will allow successfully solve the problem of wood waste disposal, decrease environmental pressure come from this waste and consequently increase level of mountain regions ecological safety.

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 application of nitrogen fertilizers allows increasing crop yields and partially increase the natural soil fertility. They have a negative influence on the environment due to the significant release of nitrogen. Hence, the technology for decreasing the N-release is proposed in this work. Obtaining of complex organo-mineral NPK fertilizers by encapsulating a carbamide granule with a phosphate-potassium shell with humates is the main aim of this work. The main tasks of this shell is slow release of the nitrogen and phosphate nutrients from the granules into the soil following the agrochemical needs of plants and prevention of soil pollution. The powdered components agglomeration of phosphate and potassium fertilizers with a small amount of liquid phase (plasticizer) allows forming a phosphate-containing coating on a carbamide core by means of the semi-dry method. This innovation allows organizing the production of such a product at the average enterprise with less capital investment. Carbamide prills, phosphate-glauconite concentrate, calcium and potassium ballast humate, and “Avatar” trace-element chelate complex were used in experimental studies. A preliminary assessment of the market prospects for such an innovation shows a high level of market attractiveness for all market participants: producers, consumers, and society

The two-stage technology of treatment of the leachates of the municipal solid waste (MSW) dumps in aerated lagoons and at municipal wastewater treatment plants (WWTP) has been studied. The study objective was to develop a technology that can be implemented at existing MSW dumps and landfills. Static and dynamic modes of implementation of both stages of the technology were investigated on the model units. Static 16-day mode was experimentally studied in the aerated lagoon conditions. As a result, we have managed to achieve almost a 2-fold reduction of COD and more than a 3-fold decrease in concentration of ammonium ions. Dynamic mode studies have established that the optimal time of leachate staying in the reactor was 10 days. Change of the relative concentration of ammonium nitrogen in the leachate largely depends on the process temperature, so in real conditions, it is necessary to adjust the modes of realization of the individual stages depending on the ambient temperature. It has been established that for treatment of leachate at municipal WWTP in a static mode at the value of the ratio of leachate dilution with municipal sewage of 1:1000, the maximum effect of treatment of both from ammonium ions and COD was achieved. The study of leachate treatment at municipal WWTP in a dynamic mode has confirmed stability of maintaining the treatment indicators in time. By implementation of the two-stage technology of leachate treatment, it will be possible to minimize environmental hazard from surface and ground water contamination in the zone of influence of MSW dumps and landfills

The concept of an open-type biological conveyor has been developed that can be used to treat contaminated wastewater. Unlike the closed biological conveyor method, it is characterized by the organized periodic selection of biomass used for biogas production. The typical scheme of an open-type bioconveyor consisting of an anaerobic bioreactor zone, an aerobic bioreactor zone, a biogas reactor zone and a phyto reactor zone is presented. The rational scheme of the biological conveyor of the open type setup for landfill filtrate purification is introduced. Laboratory studies have been conducted to determine the effectiveness of the use of nozzles for the immobilization of microbiocenosis in aerated lagoons used for landfill leachate purification.

The results of long­term research of various ways and methods of collection and processing of blue­green algae that cause “bloom” of the Dnieper reservoirs were presented. The possibility and feasibility of the blue­green algae biomass processing to biogas by methanogenesis were substantiated. It was found experimentally that preliminary mechanical cavitation of the blue­green algae biomass increases the biogas yield by 21.5 %. It was determined that the biogas produced contains up to 72 % of methane and hydrogen, up to 21 % of carbon dioxide, up to 6.5 % of molecular nitrogen. Oxygen, carbon oxide (II), hydrogen sulfide and other impurities constitute up to 2 % of the biogas volume. Biotesting of the spent substrate to determine its toxicity for further use as a biofertilizer in agriculture and forestry was held. Modern methods of electron microscopy found that the average diameter of cells of blue­green algae Microcystis aeruginosa is 3.14 microns. The flow diagram of the blue­green algae biomass complex processing was proposed. It consists in removal of valuable components for medicine, cosmetics, pharmaceuticals, production of technical detergents, mixtures of aliphatic alcohols as biofuels or additives to gasoline. Thus, it is possible to obtain more biogas by involving the spent activated sludge from sewage treatment facilities in methanogenesis. This will improve the treatment quality of wastewater of various productions.
