In most settlements of Ukraine there are no existing programs for municipal solid waste management (MSW) and schemes for sanitary cleaning of settlements, there are no registers of waste generation, treatment and disposal and disposal sites, which leads to the formation of landfills, deteriorating sanitation settlements and increase the level of environmental danger in the region. The article presents the results of research that indicate that the existing structure of the MSW management system in Ukraine at the regional level (on the example of Zhytomyr region) is imperfect. It is characterized by fragmentation, disunity and heterogeneity. The peculiarity of the system is the lack of interaction between government agencies, environmental services and the local community, which does not provide a sufficient level of control over the sanitary condition of territories, as well as collection, transportation, disposal and disposal of solid waste. The aim of the study is to strategically analyze the preconditions for the implementation of municipal solid waste management systems to increase the level of environmental safety in the united territorial communities through the introduction of environmental logistics and crowdsourcing mechanisms. The methodological basis for assessing and selecting methods and ways to improve the environmental safety of the study region by improving the waste management system (hereinafter - waste management) is a systematic approach that allows analysis of the problem and ensures search efficiency for management decisions. The SWOT and PEST analysis identified the strengths and weaknesses of the existing waste management system and the prerequisites for the implementation of a modern system of solid waste management. The increase in the number of business structures that are ready and able to implement modern methods of waste disposal and identified the availability of modern innovative management methods in public authorities and local governments. However, the low efficiency of the existing waste management system, the lack of communication and coordination of actions between stakeholders in solving the problem pose a threat to maintaining the environmental security of the region.

The chemical and hydrobiological analyses of water quality of the Uzh river of Korosten district and the city of Korosten of the Zhytomyr region were conducted. The influence of anthropogenic loads on the river eutrophication processes was estimated. The peculiarities of the course of eutrophic processes in the reservoirs of the Uzh river basin within the Korosten district and the city of Korosten were established. As a result of research, it was found that the phytoplankton in the surface waters of the Uzh river of Korosten district was represented by diatoms, as well as green, blue-green, euglenophytic, golden and dinophytic algae. Periods of their intensive reproduction were revealed for all departments of algae. Seasonal fluctuations in the content of biogenic elements of phosphorus and nitrogen dissolved in oxygen water, as well as their influence on the development of certain departments of algae were revealed. Statistical modelling of the processes of development of blue-green, and green algae as well as diatoms in the river Uzh of Korosten district on the average values of their content for less than three years was conducted. Changes in the qualitative and quantitative composition of algae during the year were used to build the models. The obtained experimental data and their revealed features were generalized in the form of linear and nonlinear statistical mathematical models of eutrophication processes. The general appearances of the functions that describe these processes; numerical values of the coefficients of the function and graphs were constructed as well as modeling errors were defined.

The water resources are the main component of technological processes occurring in industry; therefore, increasing the level of environmental safety, in particular, wastewater treatment without adverse impact on the environment and human health is relevant. The preliminary environmental analysis of the motor transport enterprise (MTE) activity has been carried out. It has been established that about twenty environmental aspects identified in the departments of technical inspection and repair and service have an adverse impact on the state of the environment. A substantial impact on the environment occurs when the sewage containing petroleum products, washing liquids, waste lubricants and contaminated by the products of tissue origin enters the soil and water objects and their resources. On the basis of the preliminary analysis, the authors have identified the environmental aspects of the company’s activity and proposed an environmental policy as an essential element for the implementation of the environmental management system. The studies conducted with the aim of determining the motor transport enterprise sewage composition revealed an excessive content of polluting chemical substances, namely: suspended substances, phosphates, iron, fats, oil products and synthetic detergents. The expediency of using carbonaceous sorbents of vegetable origin, which were obtained from the waste wood industry for wastewater treatment of the enterprise, was investigated. It was revealed that the process of sorption purification improved the quality of wastewater of the motor transport enterprise to the standard values. The proposed recommendations for the implementation of the environmental management system will gradually reduce the impact of the company on the main components of the biosphere. Effective implementation of the environmental management system will help to increase the competitiveness of the enterprise and lead to an economic effect by saving raw materials, materials, energy resources, reducing the environmental fees and penalties.
