The results of studies on the development of the composition of the charge based on low-plasticity clay using waste products from the consumption of products made of unplasticized polyvinyl chloride are presented. In addition, boric acid as a flux and titanium dioxide as a source of the vitreous phase are introduced into the composition of the charge to obtain the effects of vitrification of the surface of ceramic particles and self-glazing of the surface of the samples. The dependences of the main properties of ceramics veneer on the ratio between the amounts of polymer waste and titanium dioxide with the introduction of 5% by weight of boric acid have been established. The quantities of charge components that ensure the energy efficiency of the developed ceramics while ensuring strength, water absorption and frost resistance at a level corresponding to the requirements for products for brick cladding of buildings and structures have been determined. The use of this composition expands the range and raw material base for the production of ceramics veneer, allow you to dispose of polymer waste at any degree of purity and destruction in sufficiently large quantities.

The results of field and laboratory studies of the component and fractional composition of solid municipal waste (MSW), humidity and ash content of MSW components, which made it possible to evaluate the properties of individual fractions and waste in general, are presented. The fractional composition of MSW was determined by the method of separating waste into five fractions of different sizes: more than 250 mm, 100-250 mm, 50–100 mm, 15–50 mm and less than 15 mm. An assessment of the energy and biological potentials of MSW of various sizes has been carried out. In each fraction, the main biogenic components have been identified, which form the biological potential. The calculation of thermal properties (moisture content, ash, combustible substances, as well as the heat of combustion) for the fractions under consideration has been performed. The dependence of the heat of combustion of MSW on the particle size has been established.

The results of studies of the effect of biocoal (biochar) from sewage sludge and sawdust on the physicochemical and biological properties of soil treated with herbicides are presented. Biocoals were obtained by pyrolysis in the absence of oxygen at a temperature of 500 ° C. It was found that the combined bio-charms from sewage sludge and wood waste stimulate the vital activity of soil microorganisms, increasing their population days after 15 days by 13.5 times, increase the biodegradation of the herbicide in the soil by 5 times in comparison with the soil without biochar treatment. The introduction of the combined biochar at a dose of 5% into the soil contaminated with herbicide increased the growth rate of tomatoes by 5 times. The proposed method of using sewage sludge and sawdust makes it possible to solve not only the problems associated with their utilization, but also to effectively restore soil from pollution.

The results of research on the ecological and economic justification of the choice of technologies for the reclamation of oil-contaminated land are proposed. Economic and environmental criteria for the selection of technologies for the treatment of land contaminated with petroleum products are proposed. The algorithm of implementation of the project of recultivation of the lands polluted by oil is considered, which includes an assessment of environmental damage, compensation of losses to landowners, determination of the cost of work on recultivation of the polluted lands, justification of technology and assessment of efficiency of its application. Based on a comparative assessment of the use of various technologies for cleaning up oil-contaminated land according to the proposed criteria, the economic feasibility of using biotechnologies are shown on the example of the elimination of an emergency oil spill in the Niger Delta.

An automated system for monitoring emissions of pollutants at the sources of industrial enterprises is presented, capable of performing the functions of continuous monitoring in real time of the composition and volumes of emissions of pollutants into the atmosphere from stationary sources of pollution of industrial enterprises. The system is able to predict the possible onset of unfavorable environmental situations in residential areas adjacent to polluting enterprises and transmit the values of the volumes and composition of emitted pollutants to the State Fund for State Environmental Monitoring Data.

The results of the study of the possibility of degradation of complexones, derivatives of succinic acid (CDSA), iminodisuccinic acid (IDSA), ethylenediaminedisuccinic acid (EDCSA), trans-1, 2-diaminocyclohexanedisuccinic acid (DCHDSA) and complexones taken for comparison, derivatives of iminodiacetic acid (IDSA) and ethylenediaminetetraacetic acid (EDTAA) under the influence of microbiological preparations “Baikal EM-1” and “Rhizoplane L”, as well as borate complexes of CDSA: B-IDSA, B-EDCSA and B-DCHDSA under the influence of the preparation Rhizoplane L at a temperature 22±1^oC in an aqueous medium. It was found that within 4.5 months of the compounds taken for research under the action of Rhizoplane L preparation, B-IDSA was degraded to greatest extent (by 88%), and under the action of Baikal EM-1 preparation more than other degraded CDSA (by 86%) and EDTAA. Simultaneous destruction of DCHDSA and B-DCHDSA when exposed to the preparation taken for the experiment was not noted.

The main tendencies in the nature air pollution in Moscow from thermal power plants are considered. Emission reductions from CHP high rates are determined by a change of the main factors balance from the fuel mix capacity utilization to upgrading facilities equipment utilization optimization. On the Ochakovskaya CHP example was shown that by reducing emissions the concentration of contaminants decreased. However, the spatial structure of the pollution area has remained. Here, the low concentration zone, which is associated with the wind shadow effect, characterized of high sources, is replaced by a zone of maximum concentration, that in dangerous wind conditions velocity increases to more than 6 times. In addition, there is one zone of pollutants accumulation, within which their concentration increases by more than 7 times. For more rapidly settling suspended particles, there is the maximum concentration near the source (0.8–1.5 km). For well-scattering nitrogen oxides, sulfur dioxide and carbon monoxide are reached the maximum concentration farther from the source of emissions (5.5–6.5 km).

A brief description of the industrial and logistics center operating in the city of Novorossiysk on the coast of the Tsemesskaya Bay in the Black Sea is presented. According to remote sensing data, the area of open pit mining of rock dumps dumped during the development of three marl deposits for use at four cement plants was determined. According to the results of satellite imagery and analytical calculations, downward trends in changes in the density of vegetation cover in territories with natural landscapes adjacent to the territory of industrial facilities located on the coast of the Tsemesskaya Bay were revealed.

The results of a study of the state of soil cover in the sphere of influence of an industrial city in the conditions of Eastern Siberia are presented. In the town of Usolye-Sibirskoye (Irkutsk region), industrial nature use dominates. The acid-alkaline conditions of the soils of the city were transformed relative to the background soils. An assessment of the biochemical activity of soils is given as an integral indicator, which was assessed by the express method. Three groups of soils were identified according to the level of their activity. The diversity of soil microbiocenosis has been established. A tendency towards a decrease in the qualitative composition of microscopic fungi in industrial zones has been noted. It is recommended to increase the planting area of woody vegetation (poplar, birch, Siberian pine, fir, bird cherry, wild rose) and sowing herbs (clover, sweet clover, timothy grass, and bluegrass) to improve the environment.
