In the article, the authors describe, using the example of a selected class of technical means, their concept of replacing the “classical” linear management (exploitation) model with a circular economy (CE) model. An example of an object for which the authors plan to test the feasibility of the concept presented above is a household washing machine driven by a DC motor. The description of this object included in the article considers its complexity and multiplicity of assemblies, sub-assemblies, and elements. The DC electric motor driving the washing machine was considered the most important from the point of view of the created model, especially in terms of the possibility of maintenance and repair. For such an engine, the article presents the maintenance and disposal model as elements of the concept of building a ‘circular’ business model. The authors assumed that the formal basis for such a model would be the so-called circular model. The methodology and plan of the research carried out at Super Asia washing machine company in Pakistan were introduced, and the research results were shown. With the use of these results, an attempt was made to assess the requirements that the application of the CE business model places on manufacturers of a selected class of devices, both in their manufacture, repair, sharing and dematerialization. The concept of further research is described at the end of the article.

The aim of the following research it to provide assumptions for creating workflow efficiency model that can be implemented in repeatable production workstations. One of the main components of this model are human activities and their interactions with other elements of working environment: human and artefacts. Recognition of patterns of human behaviours within working processes gives the opportunity to find critical points that influence workflow efficiency. The subject of research is a working process existing in meat producing plant. The main method used for recognizing human activity patterns was observation and qualitative and quantitative assessments of operational activities based on video registration. Particularly, human activities were analyzed under ergonomics criteria in order to proof dependencies between process efficiency and specific ergonomic factors forming working conditions at meat plant.

The progress of digitization and the development of new technologies undoubtedly bring many benefits. However, they can also create or deepen problems related to the social exclusion of certain groups of people, such as the elderly, for whom modern technology is still largely unavailable, and even arouses a sense of uncertainty and fear (the so-called technophobia). The consequences of such a phenomenon become particularly evident in the situation of social isolation, whose unprecedented dimension is currently observed in the so-called COVID-19 pandemic era. In particular, the occurrence of the phenomenon of social exclusion combined with a pandemic situation has contributed to the development of the assumptions of the project entitled “Developing the cognitive capabilities of older people through information technology.” This project was developed by the INNOVATOR Student Science Club at the Faculty of Organization and Management of the Silesian University of Technology, and its goal is to develop a tool to support the acquisition of competences by seniors in the field of technological content, operation of electronic devices and the implementation of daily and routine activities using the Internet, e.g. shopping via the Internet or using tele advice services. The proposed tool is also to support the stimulation of the development of cognitive abilities of seniors using e.g. logical games. In the course of project implementation, a survey will be conducted in selected Nursing Homes, Retirement Homes, online forums for the elderly and through direct contact, the results of which will allow to learn the needs and possibilities of developing the abilities of the examined people, and assess the effectiveness of the designed tool in the process of transferring content and shaping competences. An element encouraging seniors to participate in the planned research will be their active participation in lectures and/or talks, workshops and discussions. The assumed result of the project will be to reduce the negative effects of isolation of seniors, improve their communication with their loved ones and reduce the generation gap. A complementary research task will be to develop a way to assess project results in qualitative and, where possible, quantitative dimensions.

Today’s world is facing the necessity of reducing air pollution. One of the alternatives is to limit pollution related to road transport by using CNG fuel. The European Union is imposing increasingly strict requirements regarding the cleanness of car fumes, and the Polish government is endeavouring to take actions aimed at reducing the pollution related to car use by planning the development of transport electromobility. In this article, the authors want to draw attention to methane as an alternative to traditional fuels. The article presents the results of a survey conducted among drivers, which regarded their readiness to use CNG-powered cars. The results indicate that while respondents appreciate the ecological value of this fuel, they are also worried about safety, which is contradicted by the analysis of CNG advantages and disadvantages.

The implementation of a new product in serial production is a very important element in the company’s functioning. Manufacturers of cars and complex subassemblies have been working for years according to the established standards of designing and implementing new products for serial production. A great emphasis is placed here on the formal side. In addition, the supplier must prove that has sufficient resources to achieve these objectives. And this is what customers verify during system, product, process and potential audits. However, despite formal approval of parts from the supplier, as well as confirmation of design and production capabilities, defective parts or components are sometimes assembled in cars and distributed to the market. Why does this happen? The answer can often be found not in the forms, manuals or procedures, but in the way the project teams communicate and cooperate with each other and with other organizations. This is confirmed by the research results presented in this paper, which show that one of the key issues requiring improvement during production implementations is not the knowledge of specialists, problems with the machine park or plant equipment, but increasing the ability of specialists and managers to effectively communicate and cooperate. It shows how important is the problem of risk assessment related to the project team for the project within the quality planning. According to the authors, the new model of project plan should be enriched with the risk assessment related to communication in the project team, as a part of the feasibility assessment of the whole project.
