Purpose: The aim of the paper is to assess the ergonomic awareness of employees covered by the integrated ergonomic diagnosis of the working environment in terms of improving technical and psychosocial conditions in selected production and service companies. Design/methodology/approach: The article explains the concept of ergonomic awareness and describes the degree of compliance of assessments of working conditions issued by the employees themselves with the assessments of ergonomic analyses carried out by experts. The ergonomic diagnosis was based on an in-depth interview with the employee, supported by a developed set of questions and employee observation in the workplace. The research has been carried out in 11 companies that are small and medium-sized enterprises in the Silesian Voivodeship. Findings: The ergonomic condition of the work system is improving, but it is still not satisfactory. Conducted research revealed the need to pay attention to employees’ perception of issues related to work ergonomics. Originality/value: The results obtained are important in terms of the proper provision of working conditions.

In a well-organized company, stock levels are precisely planned. In order to optimize inventory, various analyses of inventory usage are carried out in terms of them quantity and status. The work presents research on improving the method of managing inventory in the tire industry using the example of a selected company. The company operates warehouses in which tires for passenger cars and vans are stored. Products stored in warehouses ensure high standards. The company focuses on individuality and has a strong market position. The paper presents the results of the ABC and XYZ analysis that allow grouping tires by demand, value and number. The criteria for choosing the ABC/XYZ method are a simple way of use and low financial outlays, in contrast to such methods as MRP or just in time. Furthermore, calculations of such standards as rotation ratios for individual seasons and optimal inventory were carried out. The rotation indicator allows determine which goods are sold quickly and which goods are selling poorly, and therefore the costs associated with their storage are probably higher than from the sale of profits. As a result of the analysis, improvements were made to the inventory management system. The implementation of the proposed methods and tools for inventory management allowed the company to eliminate unnecessary inventories, reduce storage costs and minimize inventory control.

The aim of the article is to identify problems and public expectations regarding parking and the application of different parking solutions. Based on the results of a CAWI questionnaire survey, an evaluation of selected parking solutions is presented. Among others, vertical parking has been taken into account, the use of which is associated with a reduction in the area required for parking and an improvement in environmental performance characteristics at the use stage. This study is part of the search for sustainable solutions in city logistics. The results of the study serve as an initial insight into the opinions of one group of users in the life cycle of a car park. They can be used as an introduction to the eco-design of parking solutions and to compare different parking systems. The study was carried out as part of a project entitled: “Analysis of the environmental impact of a vertical parking solution using life cycle assessment at the design stage” carried out at the Silesian University of Technology.

Purpose: The aim of this paper is to present the possibilities of using hydrogen buses in urban transport taking into account technological, economic and environmental conditions. Design/methodology/approach: Analysis of international literature, Polish literature and reports related to the development of alternative energy sources in vehicles and urban transport development. Findings: The Polish government to achieve the environmental requirements of the European Union obliges local government units to ensure the share of zero-emission buses in the fleet of vehicles in use. On the basis of the conducted analysis we can say that a significant advantage of hydrogen vehicles is the total lack of emissions, a long range of up to 350-400 km and short charging times. However, a significant problem is insufficient infrastructure - not enough hydrogen stations. Despite this difficulty, more and more manufacturers are interested in producing hydrogen vehicles, and investors are seriously considering the costs and benefits of zero-emission buses. Unfortunately, none of the economic analyses that have been commissioned by Polish companies providing transport services have shown the viability of using hydrogen buses. Originality/value: The paper shows the global trends in the development of city buses with particular attention to hydrogen buses.

The paper addresses application of digitazation of production processes, which is part of organizational digitization, also known as Industry 4.0. It deals with modernization and optimization of production systems by creating models in simulation software via digital engineering. For our analysis, 8 real assembly lines were used, with an average of 15 workplaces, which were integrated into one universal line by means of simulation. The aim of our research was to create a digital twin of the real assambly lien and to analyse effectiveness of the proposed modernization universal assembly line using the generated statistical data.

The aim of European Union policy is to implement the principles of sustainable development, in which particularly important are: environmental protection and rational management of resources. Major role is given to waste management and appropriate prioritization of activities in this area. The main goal of waste management is prevention, minimization and elimination of wastes "at source", as well as encouraging efficient use of natural resources through recovery and recycling of waste. Storage process should be minimalized over the years until the complete elimination. As shown by statistics data, unfortunately in Poland, the process is very slow. The analysis of the data provided by the Central Statistical Office (CSO) over the last thirteen years shows a significant increase in the level of recovery and recycling of municipal waste. All together it was 11.654 million Mg of municipal waste collected in 2016. Wastes selected from municipal waste (paper, glass, plastics, metals) accounted for only 25.2% (2.942 million Mg), and mixed waste accounted for 74.8% (8.712 million Mg). In 2016 the recycling rate was 27.83%, composting or fermentation – 16.22%, 19.44% of municipal wastes are subjected thermal transformation and the storage level is 36.51%. Landfilling is still the most common form of municipal waste disposal.

Presentation of the possibilities of reducing CO2 emissions and the costs of heat generation as a result of the use of solar vacuum collectors. The solar vacuum collector used in the household has been characterized, the efficiency of which has been the subject of the analysis. The control system of the vacuum collector has been described. The graphs showing energy production in different months – seasons have been enclosed. Finally, a comparison of gas consumption in a household before and after installation of the solar vacuum collector has been presented. The comparisons have been made in a meaningful time period. The research results have shown months and seasons when it is profitable to use solar vacuum collectors to generate heat in the household. It has also been indicated what economic effects are obtained as a result of using solar vacuum collectors. The work shows the possibility of reducing the costs of heat energy production in a household as a result of the use of solar collectors for heating water.
