Subject. The article updates the scientific view of the environmental protection greening and the special land use regime as a special city planning means of passive sanitary protection of people from the adverse aerial and technological impact and the recovery of the environment we live in. Objectives. I identify the specifics of designing and efficient operation of environmental protection greening as an inseparable part of the urban ecosystem. The article justifies the technique for strategic positioning of respective infrastructure projects in order to ensure the protective effect. Methods. The study relies upon general methods of analysis, systematization of existing viewpoints and published findings, graphic and logic analysis, matrix-based tools to choose an administrative strategy. Results. I analyzed the air-holding capacity of economic activity in regions and the outcome of air quality monitoring as a risk factor for public health. The article pinpoints operational difficulties in the environmental protection greening facilities and strategic approaches to addressing the issues in order to improve the environmental security of industrial zones. I determine new aspects of public relations and groups of criteria to assess the effectiveness of green infrastructure projects. The article provides the rationale for fiscal incentives for investors and public-private partnership of stakeholders. Conclusions and Relevance. Considering national projects, such as Ecology, Demography, Convenient Urban Environment, I emphasize the relevance of recovering and rehabilitating obsolete environmental protection greening facilities situated in industrial zones of industrially developed cities. Green projects should indeed comply with a set of progressive results of fundamental studies carried in various scientific areas. There should be fiscal incentives in terms of taxes and depreciation on special assets as the basis for the private-municipal partnership in green assets management in order to enhance the environmental security of industrial zones.

Current Asset

Working capital management refers to a company's managerial accounting strategy designed to monitor and utilize the two components of working capital, current assets and current liabilities, to ensure the most financially efficient operation of the company. The goal of working capital management is to manage the firm’s current asset and current liabilities in such a way that satisfactory level of working capital is maintained. A study on comparison in working capital management with State Bank of India and Industrial Credit and Investment Corporation of India is analyzed to know the liquidity and current ratio. The interaction between current asset and current liabilities is therefore is the main theme of the theory of working capital management.

Gas Supply

There are investigated the influence of operating pressures in the gas supply system on the level of such energy indicators as efficiency, gas flow and gas overrun by gas equipment in residential buildings. There is established a relationship between the values of operating pressures in the gas supply system and the gas consumption level of household appliances. The causes of insufficient pressure in the gas networks of settlements are analyzed in the article. There is also developed an algorithm for calculating the change in the efficiency of gas appliances depending on the operational parameters of the gas network. It has been found that the most efficient operation of gas appliances is observed at an overpressure at the inlet of gas appliances of about 1200 Pa.To ensure the required quality of natural gas combustion among consumers and minimize gas consumption there are justified the following measures in the article: coordinating a domestic regulatory framework for assessing the quality of natural gas with international norms and standards; improving the preparation of gas coming from local wells before supplying it to gas distribution networks; auditing low pressure gas pipelines and reconstructing areas affected by corrosion; ensuring standard gas pressure in the network for the normal operation of domestic gas appliances; stating quality indicators of natural gas combustion by gas sales organizations.
