The article presents the author's methodology for the formation of a key indicator system for the evaluation of the ecological and economic potential of the metallurgical cluster. This being the case, special attention was paid to the development of an indicator system for evaluating the second-level potentials uniting the environmental and economic components of the integrated study subject. The study aims to develop a comprehensive methodology for evaluating the ecological and economic potential adapted to unique features of the metallurgical cluster of the Republic of Kazakhstan. In preparing the material, the authors used comparative analysis and integral economic and statistical indicator building methods. Individual assessments of the first and second tiers were integrated by calculating criterion integrated indicators. The study concluded that a balanced evaluation of the ecological and economic potential of the metallurgical cluster can be obtained by integrating estimates of second-tier potentials representing the joint influence of a group of enterprises in the metallurgical industrial cluster. The provisions and conclusions of the described paper can be applied by the management of iron and steel companies to justify corporate development programmes, as well as regional authorities to identify areas of investment attractiveness growth of the region. The empirical basis of the analysis was obtained from the results of studies carried out as part of the research work “Improvement of the state policy regulation for accelerated clustering of the industrial regions”, executed under grant financing of the Ministry of Education and Science of the Republic of Kazakhstan.
Strategic significance of Krasnoyarsk territory as well as Arctic Norilsk metallurgical cluster cannot be in contradiction with social sustainability of the region, what is especially important in the context of serious environmental pollution of the addressed constituent entity of the Russian Federation.Thus, the issue on the building a system of strategic analysis and management of environmental-economic potential of Arctic Norilsk metallurgical cluster (ANMC) remains relevant. In preparation of the article we used the methods of systems analysis and synthesis of available information related to the research. Building on existing economic theories, a model of the conception under consideration was introduced, the term 'system of strategic analysis and management of environmental-economic potential of ANMC' was defined and briefly characterized.The results obtained can be used as a methodological framework for the development of strategic documents on several levels: corporate, regional as well as used by the executive bodies for the purpose of justification of the directions chosen for improving socio-environmental-economic sustainability of Krasnoyarsk territory.
The issue of operated-off alkaline nickel-cadmium batteries recycling is currently relevant due to a number of aspects: economic, environmental and social. It is most acute across the national corporation JSC Russian Railways. The article deals with some technological features of operated-off alkaline nickel-cadmium batteries recycling with valuable components being extracted (from the example of nickel-cadmium storage batteries of JSC "RZD" rolling equipment). The results of leaching in Trilon B synthetic oxides solution, the presence of which is possible in the raw material being processed, are presented in the study. Based on the study of leaching processes of CdO, NiO, FeO, Femet and Fe2O3 in Trilon B solution, the dependence of complexing on the pH of the solution was revealed. The experimental site of the hydrometallurgical processing of the research center (OCGP IC) in the GMO KhMC PJSC "Uralelectromed" was selected as the testing one for the technology proposed. As a raw material for the tests, a lot of negative lamellae packed in alkaline storage batteries of two different types were used. They were obtained as a result of preliminary drying and cutting at OOO Kursk factory "Accumulator". The particle size is 90% - 0.1 mm. The results obtained during the research allowed the author to formulate a hypothesis about the practical use of Trilon B for the processing of operated-off alkaline nickel-cadmium batteries with the extraction of valuable components having greater economic, environmental and social benefits compared to methods based on pyro metallurgy.
