This article is devoted to researching, from the economic point of view, the effectiveness of the use of rush as a sorbent to absorb oil pollution. This work belongs to the fundamental and exploratory research. The influence of physical modification (grinding) on the process of oil and petroleum products absorption was evaluated. The cost of the product obtaining and the main technical and economic indicators as well as the cost of research work was identified.

The technique of definition of grains tops on a working surface of a tool is considered in the paper. Under the action of various processes of wear, the distribution of grains tops forming the relief of the working surface of abrasive tool is constantly changing. Features of formation of a working surface of circles of various characteristics are shown at grinding on various depths. Also the quantity of the grains, which have left a trace on the processed surface is defined, law of their distribution for the first time is established. The results of the research of a working surface are resulted at flat grinding of stainless steel Р6М5. Efficiency increase of production is proved.

Now in the field of chemistry of high-molecular connections the surge in interest in natural polymers which are ecologically net is observed, don't require non-renewable sources of hydrocarbonic raw materials, and also large numbers of energy resources for the production. This article is devoted to a research from the economic point of view of efficiency of use of melanin as antiagers of rubber mixes on the basis of rubbers of general purpose (on the example of SKI-3). This work concerns to group of fundamental exploratory researches. The impact assessment of antioxidants on process of thermooxidizing destruction of synthetic SKI-3 rubber by the DTA methods and researches of kinetics of absorption of oxygen was for this purpose carried out. Costs for product receipt and the main technical and economic indicators, and also costs for accomplishment of research work are shown and determined.

In article need of development of the corresponding methods and mechanisms of ensuring economically sustainable development of the entities on the basis of use of achievements of scientific and technical progress is proved. Work can be referred as in fundamental, and exploratory researches. Provisions of an economic case of efficiency of the project are calculated. The project is considered economically reasonable on the basis from these calculations.

The work proves the need of development the corresponding methods and mechanisms of ensuring economically sustainable development of the enterprises based on scientific and technical achievements. The work is both fundamental, and exploratory research. Provisions of an economic case of efficiency of the project are calculated.
