The data on the formation volume of microsilica and the results of experimental studies of effective technical and manufacturing solutions for the utilization of dust
of dry gas purifications and waste of processing the slags of high-carbon ferrochromium through the agglomeration process are presented. Substantiated arguments
in favor of using the sintering process as the most acceptable utilization technology of ferroalloy production waste and particularly at the Aksu Ferroalloy
Plant are presented. The results of laboratory and industrial tests showed that the use of microsilica positively affects the preliminary granulation of the agglomeration
mixture and provides the mechanical strength of the agglomerate comparable with the strength of agglomerates prepared by the standard technology; in
addition, experimental agglomerates corresponded to requirements in regards to the chemical composition. The complete substitution of the flux by microsilica
led to an increase in agglomachine by 10% on average. It is shown in general that the microsilica additive into the agglomeration charge composition improves the
technical-and-economy characteristics of agglomachine operation and simultaneously makes it possible to lower environmental payments for the formation and
storage of anthropogenic waste.

Based on the analysis of modern purification technologies of sewage water of OJSC "NIPIEP", an apparatus type of the manufacturing process in a sewage purification
complex was implemented. An apparatus type of the manufacturing process includes the application of modern manufacturing and design solutions of
OJSC "NIPIEP", which make it possible to reduce specific power consumption to aeration, create and hold stable high concentrations of destructor microorganisms
in bioreactors, increase the stability of the system to a nonuniform sewage supply mode to purification and nonuniformity of the qualitative composition of
the sewage, and reduce the contamination characteristics with respect to suspended substances and total biological oxygen demand (BODtot) to 3 mg/L.

A method of obtaining the sorption-catalytic material based on basalt fiber modified with manganese oxides is considered and its sorption characteristics are
determined in static and dynamic conditions. A comparative analysis of the prepared sorbent with materials often used for demanganation of water-clinoptylolite
and "Birm" catalytic material-is performed. The variation in pressure losses across the fibrous sorbent is investigated depending on the filtration rate and load specific
weight is investigated. A flowchart of demanganation of underground water using "Maranosorb" is presented and efficiency of using investments from its
implementation is evaluated.

A method of complex solving the problem of environmental pollution caused by the manufacturing activity of two different types of enterprises—copper–nickel and mining combines arranged at the territory of the Murmansk oblast. It is shown that the mining waste of LLP “Kovdorslyuda” can be used in detoxification technologies of water and soil objects arranged in the impact zone of OJSC “Kola Mining Company”. Based on the results of mineralogy and manufacturing studies of phlogopite mining waste, a gravity-magnetic concentration flowchart simple by the used equipment and maintenance is developed. In addition to the production of materials intended for phytoremediation of anthropogenic ground and immobilization of heavy metals, expanded vermiculite and product with the composition satisfying the normative requirements foreseen for building sand are isolated into separate products.

In the fuel-energy complex of Russia, 30% electric energy and 100% thermal energy are produced at thermal power stations. When combusting the steam coal, 10% ash and slag, which are arranged in storages, are formed. Volumes of works on building of a levee at storages are calculated in less detail for thermal power stations of Russia as well as negative environmental consequences in a form of emission of pollutants into the natural environment and the area of lands withdrawn to obtain the ground for building the levees are determined. The problems associated with the integrity violation of storages and environmental consequences appearing with the emergence of deformation processes in the body of levees are considered.

Coal generation of electric power is developed in Russia in the largest scale in the Krasnoyarsk krai. A problem associated with the further arrangement of ash and slag occurs at all thermal power stations. The main directions of using the ash foresee the ash arrangement at a territory of old ownerless dumps and high-temperature heating. Vertical profile planning of emptied opencast mines using ash-and-slag materials is considered ineffective. The substantiation of building the levees on the surface of storages of ash-and-slag materials is presented.

A problem of the further maintenance of ash-and-slag storages is sharply standing in the coal power generation in the fuel-energy complex of the Russian
Federation. In connection with this, the search of new engineering solutions in the field of permissible and environmentally safe preparation technologies of a storage
to reception of ash-and-slag pulps and levee building. The author's technologies propose trench boring by hydraulic excavators of the "reverse spade" type
with the simultaneous formation of levees. The developed technologies of maintenance of ash-and-slag storages provide a twentyfold reduction of expenses and
thirtyfold reduction of emission of pollutants when building the storage levees.

To reduce expenses and economize resources in production of nonwovens, investigations directed to the possibility of processing the textile waste and their
repeated use in producing new textile goods with the simultaneous solution of environmental problems are urgent. The results of studying the safety of experimental
needle-punched nonwovens of different fibrous structures made of secondary raw materials to use them as packaging for horticultural products. The basic
sanitary-chemical, toxicological, and radiological characteristics are investigated in order to prevent possible adverse effects of products from polymeric materials
for quality of food products and human health.

A considerable negative influence of harmful substances, which are emitted in premises of prolonged residence, on the human organism leads to the necessity of
a careful analysis of efficiency of foreseen methods for organizing the air exchange. A simple increase in the ventilation rate not always leads to a considerable
increase in quality of the internal air. This can be explained by the formation of dead zones inside the premise. In connection with this fact, it is reasonable to propose
new and analyze existing procedures and methods of calculation of air flows allowing for environmental and sanitary demands made to modern public, living,
and industrial premises. It is possible to avoid the pernicious influence of harmful substances on the human organism by means of organizing the air distribution
by the principle of displacing ventilation. It is also reasonable to apply mathematical modeling based on analytical methods of solution, which make it possible
to increase the exactness of results of calculation, for the preliminary evaluation of the air-exchange efficiency at the design stage.

The dynamics of the results of processing sugar beet in the region from 2010 to 2013 is presented. It is shown that four sugar plants successfully operate in the
Orel oblast according to the Agriculture Department: CJSC "Sugar Combine "Kolpyanskii"", CJSC "Sugar Combine "Otradninskii"", LLP "Livny Sakhar", and LLP
"Zalegoshchenskii Sugar Plant" with the total processing volume of sugar beet of about 2 million tons in 2012. The annual volume of formed marc by the state to
January 1, 2013, was 424.68 thousand tons of pressed marc (with humidity of 30%) and 416.72 thousand tons of wet marc (with humidity of 80%).

Opportunity and the practical importance of the continuation of developing the oil and natural gas resources on a shelf of the Barents and Kara seas and in adjacent
water areas are substantiated. Concrete areas of modern and planned sea activity associated with the production of hydrocarbon fuel and features of special
objects of the sea equipment intended for developing mineral resources of a shelf of Arctic seas are considered. The main hydrometeorological and environmental
problems arising on the way of implementing the development of mineral resources of the Arctic are analyzed. These are the iceberg danger and its relation
with atmospheric circulation over Northern Atlantic, the increased complexity of localization and elimination of oil pollution in difficult ice conditions; and the
need of detoxification and recycling the boring solutions. It is shown that the creation of scientific and reasonable system of spatial planning of water areas and
coastal territories that takes into account the climatic, oceanologic, ecological and bioproduction indicators, as well as resistance of marine ecosystems to climatic
and anthropogenic effects, will provide the solution of a series of arising problems on the way of developing mineral resources of the Arctic.

The results of the investigation into the possibility of neutralization of concentration waste of sulfide-tungsten deposit (anthropogenic sands), which contain; in
addition to hubnerite and molybdenite remained after the partial recovery, sulfides of copper, lead, zinc, and iron; and are currently liable to secondary processing;
are presented. The pH of the aqueous extract of sands varies from 3 to 4.6 while that of recycle water participating in the production process reaches 2.5.
Natural neutralizing materials such as limestone, dolomite, volcanic and zeolite-containing tuff, and clay are investigated as reagents. The experiments on the neutralization
of sands are performed in static and dynamic conditions. When determining pH of aqueous extracts of mixtures of sand and limestone in static conditions,
it is revealed that as the volume ratio of limestone to sand increases to 1 : 30, pH increases from 4.30 to 5.75. The variation in the solution pH when passing
distilled water through a column with a mixture of anthropogenic sand with limestone or dolomite was investigated in dynamic conditions. The experimental results
revealed that acid accumulated in sands is more effectively neutralized with limestone, and the acid-basic equilibrium is attained in a range of 6.5-7.5 depending
on the component ratio. Clay and volcanic and zeolite-containing tuffs have no long-term neutralizing properties compared with limestone and dolomite. It is
revealed experimentally that it is more effective to neutralize acidic anthropogenic sands with limestone.

An approximate mathematical model is considered and the computational expression for the fluid circulation velocity over the layer height in a bubble apparatus
(concentration blender) is derived. The mathematical model is constructed using the pulse balance in a boundary layer of the gas-liquid medium and pulse transfer
coefficients. Pulse transfer coefficients are found applying the Prandtl and Levich models of the boundary layer. A criterion diameter of the particles is determined
for mixing the fluid with a dispersed phase, upon increasing which, the particles will precipitate on the mixer bottom. The found expressions make it possible
to select the operational mode of the apparatus, i.e., the velocity (flow rate) of air supply for mixing; they are applied to calculate industrial mixers at various
enterprises of the oil-and-gas chemistry complex and power engineering.
