Lower Silesia

The Lower Silesia area in SW Poland is characterized by a geological structure that is conducive to mining activity. The exploitation of rock raw materials plays an important role in this sector of the economy. By the end of 2017, there were in total approximately 400 current concessions for the exploitation of rock raw materials in the analysed area (Polish Geological Institute, MIDAS database—Management and Protection System of Polish Mineral Resources). The conducted mining activity results in waste, which in the greatest amount occurs in the process of obtaining crushed road and construction aggregates, natural aggregates, carbonate raw materials for the cement and lime industry, as well as stone elements for construction and road engineering. At the end of 2016, the mining plants accumulated 26,569,600 Mg of waste. As part of the European Regions Toward Circular Economy (CircE) project, research was conducted on the volume and composition of the mining waste of rock raw materials in the years 2010–2016 within Lower Silesia. This research used the methods of statistical, descriptive and spatial analysis to identify mining plants with the highest potential for using their wastes. In the course of this study, 6 mining plants with the highest potential of using their waste for industrial production purposes were selected. In order to objectively select these plants, the methodology of qualitative multi-criteria analysis was developed, and 7 criteria were selected for assessing the economic potential of using waste from the mining of rock raw materials. An additional result of this research is a database and graphical presentation of changes in the spatial distribution of generated waste in the Lower Silesia region in the years ranging from 2010 to 2016.

Iron Ore Deposit

Components of constantly renewed cycle of formation the investment on maintaining of productivity fixed assets of production and a mechanism of ensuring the environmental and economic efficiency during exploitation of iron ore deposit is substantiated. The methodic fundamentals in investing of expanded reproduction of fixed assets on the mining enterprise for increasing the completeness of using the operational stocks of ore raw materials have been developed. The possibility and advisability of investing in reproduction of fixed assets due to additional revenue from the sale of products made from rich ore are proved, which creates a profitable conditions for processing low-grade ore stocks. It is achieved through the expanded reproduction of fixed assets, that is able to maintain the pit capacity depending on the degree and time of its deepening. On the example of Poltava MPP it is estimated the possibility of industrial complexes to accumulate profits from operations for the extended reproduction of fixed assets. It is proved that the plant will be able to allocate the necessary investment funds if mineral ore reserves is processed with a reduction of its quality.

The paper considers some ecological problems of the gold-mining enterprise in Amurskaya Oblast’. The investigations have revealed the technogenic pollution of the soil-grounds, air basin, and vegetation under the action of the processing wastes. High concentrations of heavy metals were found in the soils and vegetation in the zone of influence of the plant processing heavy concentrates at a distance of 100 and more meters. They are 2 to 90 times higher than the background values practically in all directions from the technogenic object. High TM concentrations were found also in the soils of building zone. Using the innovation approach we have elaborated the measures for decreasing the pollution negative effect on the habitat. We propose a new way of reclamation of the lands disturbed by the wastes of the mineral raw material processing with the use of the mixed bark-compost of the forest industry wastes.

In order to form methodical principles of internal strategic audit of activity the development of homogeneous well-known principles of economic audit through adaptation of specific principles is offered. The research was based on the functional-vector orientation of the objects of strategic audit, highlighting two levels of differentiation: 1 - level - types of economic activity of the granite mining enterprise (production and administrative activities); Level 2 - vectors within each of the above activities (strategic environment, development strategy, strategic gaps). This approach will allow covering as much as possible all the important provisions of the strategy for the development of granite mining companies, which will contribute to a more thorough study and support the likelihood of the latter or its refutation. The article forms a descriptive model of specific methodological tools for strategic audit of granite mining enterprises, which provides segmentation of the latter in terms of the 2nd level of differentiation of internal strategic audit of granite mining enterprises. In order to identify the risks of internal strategic audit of granite mining enterprises, their classification is formed. For the final formalization of the developed organizational and methodological provisions of the internal strategic audit of the granite mining enterprise, the structure of the Standard of the internal strategic audit of the granite mining enterprise has been developed.

Significant part of not cultivated area of Hungary is not suitable for agricultural utilization because of industrialpollution. Technologies of biorefinery make reutilization of contaminated areas possible. Biomass of plantsproduced on polluted soils can be raw material of valuable products. Applicability of biorefinery was tested on aheavy metal polluted soil, where the contamination originated from previous mining activity. Complete biomassutilization was aimed to obtain cosmetic ingredients, pharmaceutical agents, and precursors. During our researchwork 88 plant species and varieties were produced and tested for potential utilizable components. Levels ofpossible contaminants in these plants were monitored, and amounts of carbohydrates, protein, organic acid andcellulose were determined as well. Different plant extracts were tested as potential sources of biologically effectivecomponents or as raw materials for lactic acid fermentation. Our results show that biorefinery is a real possibilityfor utilization of polluted areas. Numerous plants could be cultivated on contaminated areas without increasedlevels of contaminants in their tissues, thus they can be sources of valuable compounds.

The Impact

The continuous increase in production, lack of flexibility of organizations, and lack of knowledge on sustainability have led to the depletion of raw materials and increased waste generation. Industrial symbiosis now has become a very effective solution and an essential strategy for responsible consumption and waste utilization. This strategy helps different organizations to blend their resources, share information, logistics, and waste materials to solve their problems by forming a network to increase profits. This study was directed towards identifying the barriers towards applying Industrial Symbiosis in an organization with probable solutions to them. ISM modeling and MICMAC analysis were used to visualize the impact of different barriers for implementing Industrial symbiosis in an organization and improve efficiency in terms of eco-innovation. The results of this study give experiences and rules to practicing managers in medium and small-scale industries to effectively execute Industrial Symbiosis. The study also adds to the improvement of a basic model for examining the barriers affecting IS with regards to eco-innovation and sustainable frameworks and contributes to ongoing researches on this eco-friendly idea of Industrial Symbiosis.
