  Insights in Mining Science & Technology Abstract The proximity principle is one of the main obligations in European regulations regarding waste management. However, this principle is not really implemented because it is not well defined in the law. Proximity is also linked to the new consensual concept of the circular economy, which highlights the local scale. The objective of this text is to understand the implementation of the proximity principle in the concept of the circular economy depending on waste management channels. The methodology is based on an analysis of the urban metabolism of three French cities and in-person interviews with stakeholders of waste management. The result of this research shows that the implementation of proximity is quite complex and affected by the principle of “variable geometry” depending on the types of waste. Some are managed at the local scale, such as putrescible and fermentable waste, bulky refuse, and final waste. Others, h...

  Insights in Mining Science & Technology Abstract The attention of most scholars and stakeholders is far drawn from the devastation of the environmental consequences caused by dredging related activities, which has necessitated sand filling and pilling including skewed national government policies, which has resulted to fundamental concern to halt species extinction, a situation which ecologist are not at ease with. Emphasis has been focused on alterations in the chemistry of the environment. They are worried with the numerous vanished creatures and saddened, often angered by their extinction. Man has directly or indirectly been the cause of the extinction, including the issues of depletion and degradation impact on the environment, thereby, leading to restrictions in the size, density, and distribution of organisms that threaten the biodiversity, resilience, or provision of ecosystem services. As soon as the functionally significant components of an ecosystem are...

  Insights in Mining Science & Technology   Abstract The article justifies the necessity to disclose information about the company’s intellectual capital in addition to traditional financial statements in order to provide investors and creditors of the company with an opportunity to adequately assess the company’s financial position and prospects for its future development. At the same time, the analysis of the works of Russian and foreign scientists examining the tasks solved in the report on intellectual capital, its composition and structure, their dependence on the company’s industry, its scope and specificity of activities, as well as the impact of the report on the perception of the company users of the report. Recommendations are formulated on the content of the report on intellectual capital, which most closely corresponds to the information needs of users of reporting and determines the favorable perception of the company’s prospects as a whole Key...

  Insights in Mining Science & Technology Abstract The method of physical modeling was used to study the effect of superheat temperature, cooling intensity, and vibration on the formation of the cast billets structure. It was established that, using the different combinations of the considered methods of influencing the melt, it is possible to neutralize the negative effect of large overheating on the dispersion of the structure. It is clearly shown that, regardless of the level of melt overheating and the cooling intensity, vibration processing of hardened alloys with high efficiency ensures the formation of a favorable structure of the cast billets. Keywords: Vibration; Melt; Overheat; Cooling intensity; Hypothermia; Crystallization; Billet; Structure Introduction An urgent problem of modern engineering is increasing the technical level of the machines and the aggregates, which imposes increasingly stringent requirements on the quality ...
