There was presented a new approach based on the use of biotechnology in the process of enzymatic depolymerizing of polysaccharides of waste drilling mud (WDM). There was carrying out an experimental study of the possibility of enzymatic depolymerizing of WDM using spent grains and enzymatic preparation. For experimental study was selected the most popular in the preparation of drilling fluids polysaccharides: carboxymethylcellulose, guar gum and xanthan gum. There were estimated on the velocity of its the influence of pH and different components of WDM on velocity of depolymerizing, founded the optimal quantity od spent grains and enzymatic preparation for separation of WDM. As a result was found a significant speed increase of biological destruction of carboxymethylcellulose drilling fluids and guar gum in comparison with decomposition in natural conditions. Drilling fluid from xanthan gum was not biodegradable. Reducing the time of separation of WDM will intensify the process of its recycling.

During the construction of solid municipal waste landfill-sites one of the main objectives is to secure establishment of watertight landfill bottom of the screen, to prevent contamination of groundwatersd by leachate. It was offered to perform such screen from ash concrete produced from hardening high calc ash of Kansk-Achinsk coal basin. After considering the results of the test series of samples from ash concrete was set its brand M100. Concrete class Bf 7.5 strength, brand by density D1100. Such strength in combination with the previously studied low permeability is sufficient for estyablishment of watertight screen. This technology is based on joint storage of bottom ash waste (BAW) and solid municipal waste (SMW). For substantiation the stability of ermbarkment slope from BAW and SMW at various of its founding were calculated stability analysis by the method of flat sliding surfaces. There was found that the shelf life of SMW and its gradual seal has a popsitive effect on the stability of embarkment. The stability of layered embarkment erected on the proposed technology encures even when founding the slope 1:1.

Utility pipes of centralized water supply and sanitation are among the most important elements of these systems, and how operating practice shows, the most vulnerable. Research of JSC “MosvodokanalNIIproekt” and operating experience from high duty cast iron with spheroidal graphite (HDCISG) abroad and in Russia confirmed the high performance and reliability of p[pesd from HDCISG and determined the possibility of their use on the weak and subsiding soils and karsted hardgrounds. There were presented data on reliability properties and criteria for the selection of pipes from high duty cast iron with spheroidal graphite for laying on karsted areas. There was presented an example of strength calculation of the pipeline of HDCISG on a dangerous karsted solid mass.

There was considered spatial physicochemical model of secondary gas substances of gas emissions, which allows two parallel processes: the wind carrying of the primary substance and its transformation into a secondary substance. The proposed model allows us to predict the spread in the lower atmosphere layers of the secondary gas emissions of anthropogenic origin, in particular, secondary emissions of continuous running metallurgical complexes. There was presented the solution of spatial model of the source in an analytical of chemical kinetics method. As a result become available an analytical function of the distribution of secondary substances taking into account its formation, wind transport and “destruction” of secondary substances in the atmosphere. To confirm the adequacy of kinetic model there were compared calculation results obtained by numerical and analytical method for the same conditions of the task. Both proposed models give the same results, and which of them can be used to build the fields concentration of substances of secondary emissions in the outer zone of influence of large industrial enterprises.

Escaped in the production of coke hydrogen cyanide is toxic dangerous substance. And control of its content during the process is very difficult. There were considered urgent tasdks associated with a reduction in the negative impact of hydrogen cyanide emissions generated in the production of coke-chemical production that are solved with the help of mathematical modelling. There was offered sert of effective measures to ensure the reduction of hydrogen cyanide emissions by chimneys of coke battareis. There was elaborated mathematical model of formation of hydrogen cyanide, which provides the relationship of vhemical kinetics and thermodynamics of the process, wehich allows to identify ways to ensure stable operation of coke battareis.

The connection between global and local environmental issues to energy has been shown. Global criteria for these relationships have been established. They are the amount of resources consumed and greenhouse gases emitted. The quantitative characteristics of the types of energy materials types have been given as regards these key indicators. A qualitative and quantitative evaluation of the environmental performance of various types of energy sources has been given, including alternative and renewable energy sources. It has been shown that the nuclear power has the greatest benefits in terms of solving global environmental problems.

Article is devoted to the problems arising during intensive development of hydrocarbonic raw materials. Industrial development of oil fields and gas in the Komi Republic began in the 30th years of the last century, lately in the republic more than 160 oil fields and gas are opened, plants on processing of hydrocarbonic raw materials are constructed. But for the expired period the considerable number of the problems demanding the urgent decision also collected. The environmental problems connected with emergency oil spills on transport systems, questions of rational use of the dissolved gas, and also the risks caused by existence of a large number of "ownerless" old wells are considered. Examples of violation of natural complexes are given, the analysis of the reasons which led to environmental problems is carried out, mechanisms of minimization of negative impact are offered.

Dependence of the degree of violation of the complex soil micromycetes on the level of soil contamination to be found on the example of leftbank part of Voronezh. The violation of the structure of complex is reversible and correspond the "stress" adaptive range in the recreation and residential zones of the city; an irreversible conversion to "resistance" adaptive range occur in the soil of transport and industrial zones. Microbiological parameters (indicatory species of micromycetes) must be used to monitoring of urban soils.

Modern environmental regulation in Russia creates more contradictions in legislation and administrative barriers in the industry. In this case the Constitution right to a healthy environment is not provided, the state of environment is not controlled. There were presented a basis for a new environmental regulation and proposed the approach to environmental reform, designed using the methodology of conceptual analysis and design. This approach allows design, create and support the integrity of consistent system of environmental regulation. 

This paper considers the relationship between the essence of the regulatory concepts of waste management and statistical information on waste. It is shown, that ambiguity interpretation can influence accounting system of the waste management.
