There are presented the results of studies on thermal recycling polymer car parts made of polycarbonate and polypropylene to produce activated
carbons (AC) similar by sorption characteristics to the AC being used in the practice of wastewater treatment. On the base of studies carried out, there are developed technical solutions for processing car-parts polymers with obtaining nano-sorption materials.

It is considered the creation of highly filled polymer systems based on polyethylene with optimal technological and biodegradable properties.
Obtaining highly-filled-by-starch polyethylene is found to be more cost effective than obtaining aliphatic polyesters. There are investigated by-products and concomitants of oil-and-fat industry i.e. Fusan and soap-stock as multifunctional additives in obtaining highly-filled-by-starch polyethylene. Application of additives enables to reduce viscosity, to control the degree of water absorption and promotes biodegradation of composites. The composites developed can be used in manufacture of short-term items i.e. disposable tableware, containers and other wares.

It is described the experience of using drum dryer of rotary calciner type for preparation of liquid radioactive waste to conditioning. Depending on the assortment of recyclables and the method of their final conditioning, there are proposed quantitative indexes of calcinated products quality: moisture content, granulometric composition, hygroscopicity.

It is investigated the possibility of cost-effective utilization of associated gases at remote oil fields. As a commercial product, it is proposed to synthesize eco-friendly gasoline and diesel fuel. For synthesis of these products, it is used synthesis-gas i.e. the mixture of carbon oxides and hydrogen; to produce this mixture, it is used catalytic conversion of hydrocarbons in the heated pipes. It is offered to fill the pipes with alternating inhibitory and catalytic nozzles. Pipes are heated by direct passage of electric current. Associated gases as high-energy and tech fuels can be used to generate electric power for heat conversion pipes. It is shown the complete closed, compact technological scheme of associated gases utilization at remote oil fields.

It is developed the technology of cleaning and washing of hard surfaces from contaminations of organic and inorganic nature. The technology is based on selection of an aqueous composition of detergent and testing regime of supplying detergent on contaminated equipment. Application of this technology is efficient for cleaning boilers of municipal and household equipment, aggregates of all shapes and volumes, as well as for removing contaminations from oil-loading equipment, rail and road tankers, marine tankers, ground and nderground tanks (gas stations), metal-structure surfaces, etc.

It is carried out investigation of the sorption material made of thermoplastics waste for purification of sewage and wash waters; its properties were studied as well. Manufacture of granular polymeric sorption materials is considered. Application of these sorbents is possible in industry for after-purification of sewage and wash waters from organic compounds.

It is considered the possibility of using mining waste in the form of ultramafic rocks (dunites and wehrlites) as an additive in manufacture of building ceramics. The materials obtained are shown to have good physical and mechanical properties. The addition of fine fractions of dunite and wehrlite into the mixture enables to reduce the firing temperature of ceramic materials. Using plastic molding of bricks at 11000C and with amount of additives up to 50%, the samples meet requirements of GOST. It is confirmed the possibility of manufacturing facing ceramic bricks and facade ceramics of high quality and low cost when using mining wastes

Studies have shown that heat-insulating material with high physical-mechanical properties is obtained of oil shale waste i.e. burnt rock and intershale clay without use of natural traditional materials. Application of technogenic raw materials in producing bricks promotes recycling of industrial waste, environmental protection and increase raw materials sources for ceramic materials.

Industrial activity of the timber industry complex of Primorsky Territory is analyzed. It is considered industrial activities of lumbering, woodworking and pulp-and-paper mills. The problems of timber industry waste recycling are discussed as well.

Deficiencies of the existing system of rationing of pollutants emissions into the air are analyzed. On the base of investigations and practical experience in rationing of emission, there are suggested the ways of its improving in order to obtain more reliable data on the allowable emissions standards that will promote health standards for ambient air quality in industrial areas.

It is carried out a comprehensive study of lead ions adsorption from natural waters by modified waste of caprolactam production. The main adsorption parameters required for engineering calculations of the adsorption column are determined.

It is considered the problem of recycling reticulated polymers waste i.e. spent synthetic ion-exchange pitches, which processing technology has     not yet been developed. The patterns of thermo-chemical decomposition of ion-exchange pitches waste are investigated; the composition and     properties of liquid and gaseous products is determined. The possibilities of using the products obtained as a valuable chemical raw material and     fuel components are substantiated.

It is characterized acoustic environment on the workplaces of specialists exposed to airplane and traffic noise; hygienic assessment of their labor  conditions is carried out. The results of analysis of morbidity and employment losses of professionals exposed to combined effects of noise and  infrasound are presented. Combined effect of noise and infrasound is found to reduce the perception of sounds practically the whole range of  investigated frequencies. Recommendations for protection from noise and infrasound are given.

There are considered the causes and the evaluation of arsenic contamination of natural objects in vicinity of the "Tuvakobalt" industrial complex.  It is considered also the processing of arsenide-arsenate cobalt ores at the "Tuvakobalt" industrial complex. It is offered their complex processing  using moldboardless, environmentally sound technologies with simultaneous liquidation of them as the source of pollution in the region. The cre-  ation of new chemical-metallurgical industries on the basis of ammonia hydrometallurgy technological processes is promising for processing of  technogenic and secondary raw materials in connection with low levels of capital investment and high profitability.

There are presented the results of calculation of concentration distribution of pollutants emitted by the chimneys of gas boilers in the space  between individual dwelling houses.

There are presented quantitative data on calculation of surface concentrations of contaminants formed at different stages of processing at the  "East Kamys" (Karaganda region, Kazakhstan).
