Abstract Underground mining production is an extremely important process for the economy and carried out in very difficult and complex environmental conditions. The disturbance of the balance of this environment makes it also a very dangerous process. Due to the importance of coal, mainly as an energy raw material, the process of its exploitation is carried out all over the world. The specificity of its production is mainly determined by mining and geological conditions, which determine the method of operation and the selection of machines and devices for this process. One of the most dangerous natural hazards associated with this process are ventilation hazards, including methane hazard. The reason for this threat is methane, an odorless and colorless gas, which becomes a flammable and explosive gas under certain criteria. These features make this gas a huge threat to mining operations. Its huge amounts, contained in coal seams, are released into the mine atmosphere during the exploitation process, causing a very high threat to work safety. Events related to the occurrence of methane are most often the cause of mining disasters, in which people die and the technical and mining infrastructure is destroyed. The reason for the growing methane hazard is the increasingly difficult mining conditions, and mainly the increasing depth of mining, and thus also the increase in methane-bearing capacity of the seams. Taking into account the huge impact of methane hazard on the mining process, the article discusses its impact on the safety and efficiency of this process. The results of the literature review with regard to this risk are presented and the accident statistics are presented. On the basis of actual data, an analysis of interruptions in the exploitation process related to exceeding the permissible methane concentrations was carried out in one of the mines. The problem of limiting the production process due to these exceedances is an important factor reducing the efficiency of this process. The obtained results clearly indicate that the losses resulting from these breaks deteriorate the profitability of the entire process and affect the economic efficiency of the industry. In order to effectively counteract the dangerous phenomena related to the methane hazard and to improve the efficiency of the mining production process, solutions were proposed to improve this state and the directions for further research were proposed.

Abstract The transport industry, and especially aviation and maritime transport, emits significant amounts of CO2, adversely affecting the environment. The Sustainable Development Goals not only indicate the need to reduce CO2 emissions, but also to provide access to information on the amount of emissions, on top of their environmental and financial impacts. The main source of this type of information is found in financial and non-financial statements prepared by entities of the transport sector. CO2 reporting disclosures should be subject to the principle of true and fair view ensuring adequate materiality, transparency and comparability of information. The aim of the article is to assess the scope and method of reporting information on CO2 emissions in the financial and non-financial statements of selected groups of the air and maritime transport sector. By means of content analysis, disclosures on this subject were reviewed and compared against the applicable legal regulations in the field of CO2 emissions reporting for the industry. The results of the research indicate a significant differentiation in the methods of reporting, in particular relating to the valuation and presentation of CO2 emission allowances in reports on the financial position in air transport and the manner and scope of reporting non-financial information in maritime transport. The obtained results indicate insufficient comparability of the reported information and a need for harmonisation of the provisions of law regarding the scope and forms of reporting. The findings also indicate a need to combine financial and non-financial information in single reports in order to properly interpret the effects of emissions.

Abstract Rainwater management is one of the important problems of cities. At very strong downpours, storm sewer systems may not capture the rainwater, which floods pavements and roadways. The water flushes fuel and oil traces after vehicles, fallen debris, and other pollutants, which will be moved to the ground, ponds, rivers, seas, etc. In past, the problems were solved using engineering approaches – a set of rainwater receivers, a duct network, and at best, wastewater treatment plants. Now, the sponge city concept is a better solution that uses a biotechnological way for throttling water flows, drainage, and purifying them. The work aims to improve the design of roads to fully absorb rainwater from them with maximum convenience for road users. We propose a design of roads using special “green structures” – rain-garden bands along the sides of roadways. We tested its ability of water capturing on the example of Kyiv city by matching the ability with the strongest precipitation observed. In addition, the proposed plants can extinguish the energy of bouncing cars during road accidents for the protection of pavements.

Abstract The aim of this study is to analyze the relationship between the sector of the conducted business and the approach to the ownership and rental of real estate used for business purposes, particularly considering the short-term aspect and space sharing. The research uses data obtained from 102 randomly selected Polish enterprises to explore the relationship between the sector and (1) the preferred legal title to real estate (2) acceptance of short-term rental of real estate and (3) acceptance of space sharing. The relationships in all three areas were found. The sectors of production, hotels and restaurants, construction, and transport lean towards ownership. Enterprises operating in the sector of services and trade prefer rental. The sectors of production, hotels and restaurants and transport are skeptical about short-term rental. Services and trade and construction are open to such rental. The sectors of production and hotels and restaurants are skeptical about space sharing. Transport, trade, and construction are clearly open to such an opportunity. The research limitations are as follows: the research is limited to Polish randomly selected enterprises only, and the results cannot be generalized. The originality/value of this paper is revealed in the fact that this paper outlines a short-term rental and ownership perception from an entrepreneurial-managerial view. The novelty of the presented results consists in filling the gap by conducting the research considering the specification of rental and its narrowing down to a short period and space sharing in the context of the sector.

Abstract The purpose of this study was to analyse the relationship between the aspects of ergonomics and economics in the construction industry. Ergonomic cost calculation mainly as a result of down time due to accidents and incidents was evaluated. The impact of ergonomics intervention on construction economic in the logistics network was also determined. This impact was simulated using an annual total of accidents for the year 2021. Organizations, particularly businesses, must implement ergonomics diagnosis measures in order to reduce occupational hazards and accidents in their supply chain. Ergonomics measures are implemented to reduce and eliminate workplace accidents, but most manufacturing companies and employers overlook this aspect because it is seen as an expense. The case study was performed in Hexagon Steel Construction company. This is due to the fact that such a business operative is responsible for a wide range of activities in the logistical network, from manufacturing to warehousing and distribution, and finally to final structure installation on the construction site.

Abstract Waste management is a very important issue for the sustainable development of the modern world. The metallurgical industry is an industry that has been generating and still generates large amounts of waste that may have a negative impact on the natural environment and human health. Metallurgical waste comes from current production and is collected in landfills/heaps. Any research enabling the management of waste, including metallurgical waste, is justified. This study presents the results of research on waste that can be used in the production of aggregates – research related to natural radioactivity and the introduction of hazardous substances into water or soil. The study highlights the diversified chemical composition of metallurgical waste, which requires detailed research of the waste before it is directed to the production of aggregates. Aggregate, as a building material, is subject to specific legal (normative) regulations. Metallurgical waste that meets the requirements for the protection of the natural environment and human health should be used for the production of building materials - it is an environmentally friendly activity that implements the principles of sustainable development.

Abstract Understanding and promoting the CSR is an important societal issue, and circumstances force modern-minded management to abandon the classical model of only the necessary fulfilment of legally set obligations. There has been a lot of study done on employee perceptions of CSR in the workplace, but very little has been done on how employees comprehend CSR and how they received it at their work-place in chosen countries. Research was carried out based on a questionnaire survey with data collection from September 2020 to March 2021, with a total of 1103 respondents. The aim of the article is to describe the CSR concept among employees meaning in selected countries: Zimbwabwe, Czech Republic, Poland. The measuring instrument used in the study was the questionnaire method, in which the research tool is a questionnaire CAWI - Computer Assisted Web Interview. It was shown that enterprises apply CSR activities, but they are not fully aware of the CSR benefits.

Abstract Society, companies and institutions are involved in a digital transformation that can be pervaded in various industries or sectors, and this also applies to communication, sales and distribution channels. The possibilities of e-commerce have also increased and world trade has been further developed. In 2020, more than two billion people bought goods or services over the Internet. Customer satisfaction depends on the solution of the last mile process, the method of picking up shipments as well as the time and place of picking up the shipment. The most common forms of off-premises delivery are automated parcel locker or machine (APM) and pick-up and drop-off delivery (PUDO). The aim of the paper is to analyse the level of the PUDO and APM network in European countries and in the V4 countries with regard to the size of the country and the population. For this purpose, it was necessary to focus on determining the population per 1 PUDO and the number of inhabitants per 1 APM in individual European countries and subsequently in the V4 countries. The obtained data were processed and recalculated in Excel. The results showed that within European countries the best values were achieved by Finland with 526 inhabitants per 1 PUDO and Spain with 188 inhabitants per 1 APM. Regarding the V4 countries, the Czech Republic achieved the best value in the case of inhabitants on PUDO with 729 inhabitants per 1 PUDO and in the case of APM Poland with 3,184 inhabitants per 1 APM.

Abstract A wide range of elastomers allows to manufacture products that meet high demands of consumers. They are prepared from a mixture of several rubbers, rubber chemicals, additives and reinforcing materials (fibres), which allows you to obtain the desired properties of the products. The other components of rubber compounds are fillers, carbon blacks and plasticizers. Rubber chemicals supplement the mixture in small quantities of related products, which affect vulcanization and regulate their properties, so they have an irreplaceable role in the preparation of rubber products. The aim of experimental part is to assess the properties of the degradation environment on samples of rubber composites to change their properties. The result of the performed mechanical tests to evaluate and compare the obtained values of mechanical properties of rubber compounds and to predict the possibility of biological degradation of the tested material.
