The paper sets forth a new method for determining emissions of pollutant during the life cycle of wind farms by aggregated data. The rationale for the use of aggregated data is given. Within the framework of method, an algorithm was developed for determining the emissions of CO 2 eq, SO 2 eq and PO 4 eq in the production of elements of wind turbines and wind farms. Classification of elements of wind turbines by parameters and technical characteristics of elements with subsequent division into groups is given. Formulas for calculating emissions of pollutant at the stages of the wind farms life cycle are given and substantiated. Within the framework of the method testing, emissions of CO 2 eq, SO 2 eq and PO 4 eq were calculated during the life cycle of two onshore wind farms with an installed capacity of 70 MW with wind turbines, differing in the parameters and technical characteristics of the elements. Calculated emissions of pollutants, which can be prevented when choosing the wind farms as power sources and determined the environmental effect of their use when comparing with thermal power plants.

The experience of introducing circulating water systems, both in production processes and transportation, was presented. It was shown that circulating systems, for example, using flotation, can be effective when working with several reagents, including coagulants and flocculants. It was concluded that the obtained cleaning results meet the requirements for the quality of recycled water in the paint and varnish and galvanic industries, as well as in car washing. Promising development was highlighted through the introduction of such circulating systems using a modern range of reagents, small doses of which achieve high technological performance.

Catalytically active materials were obtained by processing the red mud of the Bogorodskoye field for the treatement of gas emissions from carbon monoxide. It was found that that the use of acid leaching followed by precipitation of sparingly soluble compounds with ammonium hydroxide leads to the production of materials with an iron content of 55% by weight according to elemental analysis. The samples were found to have higher specific surface area (154.8–155.7 m 2 /g) and porosity (0.275–0.311 cm 3 /g) and higher catalytic activity in the CO oxidation reaction compared to untreated red mud. It was confirmed that impregnation of the surface of refined products with copper oxide in the amount of 5 % by mass in terms of metal significantly increases the catalytic activity.

The actual aspects of environmental financing are considered. A comprehensive assessment of the state of environmental protection activities in the CIS countries based on the results of recent years is presented and an analysis of its financing for various types of natural resources is carried out, as well as changes in relevant environmental indicators are studied. It has been revealed that despite the growing volumes of investments aimed at environmental protection, the environmental indicators of the Commonwealth countries do not always show corresponding positive trends.

The use of mining and metallurgical industry wastes containing calcium, magnesium, and strontium carbonates is described. The initial compositions and transformations occurring during the firing are considered. The best composition was chosen according to the results of laboratory studies, and based on that, ceramic brick was studied in real production conditions. The possibility of using mining and metallurgical industry wastes (dolomite and cake) as coloring pigments in the production of ceramic bricks has been theoretically substantiated and experimentally proven. Magnesium and strontium carbonates, along with calcium carbonates, participate in the formation of multicomponent systems, on the basis of which it is possible to obtain wall ceramics that meet modern requirements.

New ways justified to improve technological nature-convergent principles and schemes for the rational use of resources in water treatment and processing. Main principles for the rational use of resources, nature-convergency and ressources substitution were developped. The impact of ultrasound on the production of highly reactive sodium hypochlorite was revealed. The know-how of an active chlorine-containing reagent from underground mineral waters was studied and its effectiveness in disinfecting natural and waste waters of pulp and paper and fish processing industries was proven. A new formula for fertile soil production based on tap water sediment was developed.

The analysis of heavy metals and arsenic contamination of soils of the urbanized territory of Svirsk (Irkutsk region) is presented. The features of distribution and concentration of mobile forms of elements – toxicants in soils of different functional zones of the city are revealed. It has been established that the main pollutants of the soils of Svirsk are As, Zn, Pb, Cr, Fe and Cd, which have high accumulation rates. Mainly high–contrast polyelement geochemical anomalies Fe–Pb–As–Zn– Cd–Mn and Cu with extremely dangerous pollution levels are formed in the soil cover of industrial zones. The soils of a private residential area are characterized by local contrasting four–element anomalies Zn–As–Cr–Mn with a dangerous and extremely dangerous degree of pollution, multi–storey residential sector – two-element low-contrast anomalies Cr–Cu with a dangerous and moderately dangerous ecological situation.

Biodegradable composites based on a solution of polyvinyl alcohol (PVA) and by-products of plant origin were created. The concentration impact of vegetable fillers on the elastic-strength, moisture-absorbing and biodegradable properties of composites based on PVA solution were studied. The biodegradability of the resulting films was evaluated by instillation and exposure in the ground for 30 weeks. It was concluded that all the developed compositions can be used in the packaging industry.

A method for removing nitrogen oxides from industrial of exhaust gases by catalytic reduction using fibreglass carriers was studied. It was noted that this know-how reduces nitrogen oxides and oxidizes carbon monoxide and hydrocarbons to safe compounds at moderate temperatures without additional reagents (ammonia, urea). It was proven that catalytic blocks structured with corrugated flat metal meshes provide the highest catalyst activity, and the best carrier is macosatin fabric. It was concluded that the described catalysts are characterized by high internal mass exchange rate in combination with low hydraulic resistance, high permeability, and the possibility of being used in dusty flows, which makes them very promising for treating various flue and exhaust gases.
