Assessment of the negative impact on the components of the natural environment during the scheduled and repair outages of gas-compressor units in transportation the process of the natural gas was the purpose of the performed scientific work. The results of the monitoring studies, in which the methane concentrations were measured in the atmospheric air near the source of pollution and on the border of the sanitary protection zone during volley emissions of natural gas into the atmosphere, are presented in the article. In addition, a method that eliminates the release of the natural gas into the atmosphere during the scheduled and repair outages of gas-compressor units are suggested in the article. The method is based on the redistribution of gas flows and the direction of natural gas to the gas distribution station. Volley emissions of methane into the atmosphere will completely eliminated as a result of implementing this method. The proposed technical solution is aimed at reducing the negative impact on atmospheric air near gas compressor stations. Moreover, the proposed method is able to minimize the economic damage to gas companies because of the loss of marketable products.

At present, monitoring of air pollution near industrial facilities is one of the most urgent tasks. Its implementation is a requirement of Article 42 of the Constitution of the Russian Federation and the basis for the ecological well-being of the population. This problem is especially critical for the production facilities located within residential areas or in close proximity to them. The scientific article presents the results of a monitoring study of the air pollution in a residential area exposed to the negative impact of the storage of primary oil refining waste. Within the frames of the scientific research, the analysis of the stock materials of the enterprise was conducted; field observation was performed on the territory of the considered enterprise and the construction of ecological cartographic models was carried out, reflecting the level of the air pollution in the territory under consideration. The study also carried out a literary review and presented a list of the main existing technologies for the utilization of oil sludge to improve the quality of the air in the region under consideration.

At present, the development and optimization of methods to eliminate the consequences of soil contamination with hydrocarbons is gaining increasing economic and social importance; it is the basis for sustainable development of the oil industry. Within the frames of the scientific research, a review of literature was carried out in the sphere of utilization of organic wastes from the food industry in reclamation of oil-contaminated soils; an experimental study of efficiency of the use of wastes from the brewing industry in the process of bioremediation of oil-contaminated soils was conducted and phytotoxicity of these wastes was determined. Experimental research was conducted at different initial concentrations of oil in the soil, which allowed to establish the optimal range of oil pollution level at which the efficiency of brewing waste use is the highest. Thus, at low concentrations (1000–2000 mg/kg), the dynamics of oil concentration decrease in the soil remained preserved throughout the whole duration of the experiment, and the efficiency of oil destruction in the soil exceeded 98%, which confirmed the overall efficiency of application of brewing waste for reclamation of oil-contaminated soils.

The Paris Agreement came into force in 2016. Now, there are 196 parties to this Agreement, including Russia. The purpose of the accommodation is to hold the increase in the global average temperature below 2°C and to make efforts to limit the temperature increase to 1.5°C. Another important goal of this Agreement is to reduce greenhouse gas emissions, according to UNFCCC-2015. Each participating country at the national level plans special activities that will help to achieve these goals. In general, this should reduce the rate of global warming. The goals of the Paris Agreement can be achieved either by introduction of new technologies that exclude the formation of a large amount of carbon footprint or termination of the usage of fossil fuels for electricity production. The formation of a carbon footprint is observed at all mining enterprises, regardless of the extracted raw materials. In this case, the amount of carbon footprint depends only on the extraction technologies and the success of ecological measures.

The research is devoted to assessing the negative impact of the amber-succinite deposit in the Kaliningrad region as one of the sources of complex pollution of the Baltic Sea waters. The Baltic Sea is one of the most polluted water bodies in Europe today. There are many natural and anthropogenic factors that cause this ecological situation. Industry is one of the significant contributors to the pollution of the waters of the Baltic Sea. The industrial wastewater discharged into the Baltic Sea often does not comply with the state ecological standards. The wastewater disposal system modernization by creating a recycled water supply is one of the most effective ways to reduce the negative impact of industrial wastewater on the Baltic Sea ecosystem nowadays. This technological solution allows to significantly reduce or to completely prevent the discharge of wastewater into the Baltic Sea.
