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.

In the era of global market and internationalization of enterprises, an extremely important element influencing the competitiveness of companies is ensuring high quality of manufactured products, taking into account the requirements and expectations of buyers. At the moment when defects appear in the manufactured product, the production plant ceases to meet the expectations of customers. Not only is this related to the costs of production or complaints, but above all to the loss of credibility and good customer opinion. It is extremely important to identify and analyze the causes of this phenomenon as soon as possible, without allowing it to repeat itself. The problem of manufacturing defects becomes even more important when it poses a threat to the health or life of the customer. This also applies to products manufactured for the purposes of food protection. This article presents the results of the research that enabled the development of a method to reduce the production defects of a selected product in a glass factory. In order to achieve the goal, an analysis of the production process of the selected glass packaging was carried out, which allowed to identify defects and determine the causes and effects of their formation. Based on the presented research results, improvement measures have been proposed, consisting in developing a new organization of work in the area of quality control.

Statistics from the Central Statistical Office (CSO) state that the total number of motor vehicles and mopeds in Poland in 2019 was 31,989,313 units. According to the Central Register of Vehicles (CEPiK) maintained by the Ministry of Digitalisation, the number of motor vehicles registered in Poland in 2019 was 23,878.8 thousand units. Among them, 18,302.4 thousand passenger cars were registered. The constantly increasing number of vehicles on the road has a significant impact on the deterioration of road capacity and drivers’ frustration with parking, especially during rush hours in the centres of large cities. Hence, urban logistics, including the country’s parking policy, is extremely important to a significant proportion of citizens. Unfortunately, citizens have different perspectives on parking issues. Most drivers expect to be able to leave their car as close as possible to their destination, while some residents, especially non-motorised ones, are against the conversion of free city space into car parks. In response to the presented issues, a comparative analysis of selected types of car parks was carried out. This analysis was one of the stages of the 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.

Losses of drilling mud and other fluids is the one of the major types of drilling troubles. Annual time losses for their elimination by oil and gas companies are huge. The factors, influencing the mud losses and regulating the direction of the further works, can be divided into two groups: geological and technological. Conducted studies on the use of an insulating composition based on chromium acetate made it possible to identify: the use of the insulation composition on the chrome acetate base allows considerable reduction of time required to eliminate disastrous circulation loss without installation of cement plugs; avoiding BHA replacement; avoiding drilling-in after bullheading and overlapping of lost-circulation layer; low cost, possibility of fast preparation, as it does not entail the delivery of additional chemicals, which also contributes to reduction of time required to eliminate disastrous circulation loss; the use with every type of drilling mud. Basing on the positive experience of the use of this composition in the neighboring regions and considering its economic side, the technique can be used in regions of the Udmurt Republic.

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.

Competitiveness and innovation are indicators of the strength of the circular economy (CE). Eco-innovations are highly important because they lead to the reduction of energy consumption and to lowered CO2 emissions. They also contribute to effective waste management and the use of materials that are less polluting or dangerous to the environment. These investments will increase Europe's economic competitiveness through environmental protection, the creation of new jobs and the promotion of entrepreneurship. The article indicates the scope and directions of changes in the implementation of eco-innovations in Poland and the obstacles that slow down the process of their activation. The presented ecological innovations were divided into: process, product, organizational and marketing. The data analysis was based on reports from the European Union (Eurostat), the Central Statistical Office (Polish: GUS) and the Polish Agency for Enterprise Development (Polish: PARP). In the summary, attention was drawn to the biggest barriers to the putting into place eco-innovations. Among these are the lack of financial resources, too high costs of eco-innovation implementation, legal obstacles and bureaucracy. The benefits for the environment are obvious, but investment costs often outweigh the financial possibilities of manufacturing or service, and, therefore, they are a factor slowing down the introduction of CE in Poland.

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.
