Recycled Material

The recycling potential is being actualized due to the trends in the production and use of powder and liquid combustible materials from the waste of a mining enterprise in the production cycle of mining, enrichment and processing (polymer packaging and containers of explosives, large tires and rubber products during the operation of mining vehicles, coal powder and coke breeze during enrichment and coking of coal, waste oil products during the operation of vehicles and mechanization equipment). In the material under consideration, a SWOT analysis of the possibility of using the recycling technology of materials in the manufacture of the simplest explosives in the northern and arctic regions of Russia is carried out, including consideration of geological, natural, climatic, economic-geographical, environmental, technological and technical aspects. On the basis of the presented detailing of the indicators of the considered aspects of the SWOT analysis, their role is shown and the value is highlighted when using the technology of recycling materials for the simplest explosives in the development of medium and small deposits. The possibility of obtaining recycled material used for the manufacture of the simplest explosives at mining enterprises from alternative manufacturers is shown.

Cities with their innovative capacity are key places to address critical climate, environmental and health challenges. Urban experimentations, such as Living Labs, can represent a starting point to reintroduce resources into the production cycle and reduce environmental impacts, embracing the paradigm of the circular economy (CE). According to recent studies, Living Labs at a city scale could generate significant environmental benefits, improvements in quality of life and positive impacts on citizens’ health.1 This paper aims at presenting the case of the Torino Living Lab on Sharing and Circular Economy (LLSC) to point out possible future scenarios of urban sustainable policies. The case study is analysed in five sections: (1) the description of the new permanent laboratory proposed by the City of Turin; (2) the past experiences of Living Labs in Turin; (3) the birth of LLSC and the involvement strategy; (4) the introduction of the eight admitted experimentations. In the light of the results collected, the last paragraph (5) came up with the Strengths, Weaknesses, Opportunities, Treaths (SWOT) analysis in the LLSC. Eventually, it deals with the research question by offering a common ground for global and local policies focused on sustainability and CE.

The intention to preserve a comfort habitat for the mankind finds expression in the attempts to decrease the anthropogenic impact on the environment. A concept “carbon footprint” appeared, which reflects input of some kind of activity to the environment pollution. The desire to influence producers’ behavior and make them decrease their carbon footprint under existing conditions results in elaboration new kinds of taxes and duties, stimulating modernization of technological process and decrease of harmful substances emissions. It is expected that in case of the taxes being implemented by big metal products consumers, such as Western Europe, will result in considerable change of the metal products market. An analysis of various ways of metal producers’ adaptation to operation in conditions of the expected changes presented. It was shown that such organization measures as lobbying of interests and artificial differentiation of business on provisionally “clean” and “dirty” will result in a rather restricted result. Thereupon actuality of a radical modernization of production capacities to decarbonize the technologies of steel production grows. Replacement of the carbon by hydrogen for reducing of iron oxides is the most advanced technological solution. At the same time, the hydrogen metallurgy is not yet implemented anywhere on industrial scale, and the hydrogen application in the production cycle results in a lot of questions, having not yet definite answers. A SWOT-analysis presented, demonstrating advantages and disadvantages of hydrogen technology mastering by metals producers.

To improve the efficiency of the mining industry, it is necessary to coordinate all production processes, which allows reducing unproductive downtime of mining and transport equipment, increasing their productivity, and reducing the cost of operations at all stages of the production cycle. To achieve this result, the article uses a systematic approach to consider the features of planning the work of all departments of the coal mine, starting with drilling and blasting operations on the sites and ending with the shipment of finished products to consumers. Based on the example of JSC “Chernigovets” in the Kemerovo region, the article considers a two-level model for planning the work of all divisions of the enterprise for a month, taking into account the dynamics of resource use of production and transport sections. Taking into account the uneven performance of production operations and the wide variety of mining equipment used at the stages of preparation, excavation, excavation, transportation, processing and shipment of finished products to external rail transport, it is possible to use a hierarchical two-level system with aggregation of processes at the first level and their detail at the second level. Using the dynamic programming method allowed us to solve the problem of planning the activities of all divisions of the enterprise at the first level and identify the boundaries of changes in the planned indicators at the second level, which do not worsen the results achieved at the first level. The proposed method of planning the operation of the mine will allow you to quickly track the achieved indicators, compare them with the planned ones and, if necessary, adjust the work of the enterprise’s divisions in real time to achieve the best performance indicators of the coal mine as a whole.
