Purpose: The purpose of the publication was to present the opportunities offered by the implementation of Cleaner Production projects in terms of improving the efficiency of supply chains, in accordance with the principles of transformation to the circular model, and to review indicators characterizing green supply chains, indicating the direction of further, in-depth research in a given area. Methodology: Fourteen entities that implemented implementation projects under the Cleaner Production Academy were analyzed. On this basis, the degree of adaptation of selected enterprises to functioning in the circular model in such areas as transport, reverse logistics, cooperation, and eco-design was discussed. The economic account related to the above was balanced. implementations, then the results of the projects were summarized in the form of economic, environmental, and social indicators. Findings: Confrontation of the ways of implementing changes in the area of improving the efficiency of the functioning of the supply chains of the analyzed companies with the effects that have been achieved, showed the greatest commitment to projects reducing material losses and reducing the costs of internal logistics. The least involvement was found in the area of activities such as establishing cooperation with other companies or developing the service sphere. Research implications: Further research should focus on an in-depth analysis of examples of good practice in the area of cooperation and development of services for companies taking action to improve the efficiency of supply chains. Enterprises have a chance to significantly reduce costs and improve the environmental effect through activities in this area, which should be confirmed by examples of implementations. Practical implications: The analysis of the indicators suggested in the literature related to the transformation of supply chains towards closing the loops indicates the need to create standards that, on the one hand, will enable verification of the effects of implementations implemented as part of Cleaner Production projects, and on the other hand - will constitute know-how for companies. These activities, so far rarely undertaken by companies, are generally low-cost and probably enable achieving very good economic effects in the long term, which should be checked.Social implications: The development of activities in the social area by companies in the field of development of the service base and cooperation will have an impact on other indicators (economic and environmental), which is indicated by numerous examples of effects in this area in the world literature. Originality: The article takes a very important direction of further research in the area of know-how for taking actions aimed at closing supply chains. The authors look for the most universal indicators and pay attention to the need for their mutual complementation. The collected material is the starting point for further in-depth analyses.

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.

The aim of the research was to answer the question whether the remote work imposed on workers during the COVID-19 epidemic has an impact on their well-being, and if so, how. The research material consisted of the results of a survey conducted among the employees referred to remote work in connection with the announced state of the epidemic in Poland. The research was conducted in the period from July 31 to August 19, 2020. The research was conducted using a questionnaire method, the study was attended by 199 respondents. A survey questionnaire was used in the study and the results obtained were statistically processed. The research carried out allowed us to obtain the results of the self-assessment of employees referred to work in the homme-office in terms of their mental well-being and physical well-being.

A research was conducted among the employees referred to work in the home office in connection with the announced state of the epidemic in Poland. The research was conducted using a questionnaire method, the study was attended by 199 respondents. The research is burdened with an error in the selection of statistical sample units, which resulted from the respondents’ involvement and their truthfulness. The aim of the article is to assess the activities of employers from the private and state sectors in Poland, related to the delegation of employees to work in the home office, and to analyze the skills and possibilities of self-organization of work by employees. An important result of the survey was to demonstrate the differences in the behavior of public and private sector employers. The study shows that the private sector has adapted better to sudden changes than the state sector.

Problems related to work safety have been accompanying humanity since the dawn of time. In times before the Industrial Revolution, human and animal muscle strength was used to work, and "safe work" solutions were developed and introduced individually by the user or supervising the work. Only a change in the way work was done due to the industrial revolution, the introduction of new energy sources, the transformation of manufactories into factories and the birth of the working class brought about greater, concrete changes. It was at that time that various machines and devices began to be introduced into the workplace, which on the one hand improved work and on the other hand created more and more potentially dangerous situations. Security was started holistically and institutionally. With the transformation and return of capitalism, the subject of real work safety returned. Health and safety was to be not only a fashionable slogan, but a value that was supposed to guarantee profit - in accordance with the principle that accidents reduce productivity. It was also connected with the process of adapting Polish law in the field of health and safety to the law of the European Union (EU), which resulted from Poland's pursuit of EU membership. Moreover, an important factor initiating these changes was the interest of enterprises in quality management systems compliant with the ISO 9000 series and environmental management systems compliant with the ISO 14000 series, and related attempts to adapt the system management concept to the area of occupational health and safety, resulting in PN-N standards 18000 series. This publication analyzes the new standard PN-ISO 45001:2018 - "Occupational health and safety management systems - Requirements with guidance for use" comparing it with the standard PN-N 18001:2004 - "Occupational health and safety management. Requirements".
