The article presents the history of the development, and the reasons for the creation of the SEVESO Directive, with particular emphasis on the latest Directive 2012/18 / EU of the European Parliament and the Council. The SEVESO III directive imposes detailed requirements on the plant operators regarding their control against major accident hazards related to dangerous substances. Individual countries of the European Union apply various requirements (following SEVESO III or more rigorous ones) for industrial plants. In Poland, the requirements of the SEVESO III Directive have been implemented in the Environmental Protection Act, and its executive acts. The SEVESO III Directive requires that the citizens of a given country have access to information about high and increased-risk establishments. In Poland, this requirement is met through the website www.mapy.geoportal.gov.pl. People can find information on establishments posing a risk of a serious industrial accident. The article presents how to use the portal and what information can be obtained there.

This article presents the methods of processing gold-plated pins from, among others, used computer equipment and discusses the research results on the recovered metal. Due to the relatively small structure of the pins and the fact that the gold layer is only a few microns thick, recovering gold from them constitutes a significant challenge. On the other hand, gold is a precious metal which enables the collective removal of other metals to obtain pure gold. The suggested method involves compacting the gold-plated pins into an anode form and carrying out the electro-refining process. Metals, such as copper, tin and iron, pass into the anode sludge from which they can be extracted or serve as a commercial intermediate sold to smelter plants. The anode sludge was melted in the flame of an oxy-acetylene torch in a graphite crucible by adding borax. As a result of the melting, several metallic precipitates were obtained. Then they were hot-incorporated into a sample with a diameter of 30 mm and a height of 12 mm. Eventually, a pure gold alloy sample was obtained, which contains Cu 40.69%, Sn 9.61% and Au 48.58%.

The current market environment is affected by several fundamental changes. A large number of these affect manufacturing companies the most. They are forced to continuously reduce their costs, improve the quality of service to their customers and adapt to a highly competitive environment. However, environmental requirements for production processes have become increasingly important in recent years. These are underpinned by legislative changes that put enormous pressure on manufacturers. Often, environmental requirements can also determine the economic success of a manufacturer. The areas that have a significant environmental impact include metallurgical technologies. These are currently predominantly based on the use of coke, which is produced from high-quality hard coal. The mining of raw materials also has significant environmental impacts. The article deals with analysing downstream production processes regarding their environmental impact. These are the areas of mining, ore processing and iron and steel production. These areas can be seen as downstream production stages. Iron ore processing and iron and steel production often occur within a single production organisation. Therefore, a possible overall optimisation in handling environmental impacts and treating pollutants can be assumed. The secondary objective of the paper is to analytically assess the potential reuse of the produced waste in production processes. The article is based on the research results carried out in a selected metallurgical enterprise in the Czech Republic.

This article analyses the recycling of secondary waste in Polish recycling companies. An innovative method of processing PCBs is presented and trends that should be followed by plants processing non-ferrous metal waste are indicated. In conclusion, it is emphasised that the Polish WEEE recycling market is still at the early development and growth stage and the most important goals that enterprises should set themselves include cost optimisation, improvement of waste management logistics and increases in the level of recycling.

Iron production is one of the production processes that create a large number of negative externalities towards their surroundings. Iron production is based on the use of a wide range of production operations, which include not only the blast furnace process but also the treatment and processing of ores, sintering, pelletizing and processing of metallurgical waste and its possible storage. All parts of the blast furnace process can have a negative impact on the environment. Within the individual parts of the blast furnace plant, a number of pollutants are produced which negatively affect the environment. They can have both solid and gaseous states. In the case of solid emissions, it is airborne dust, and the gaseous form represents pollutants in the form of sulphur, nitrogen or carbon oxides. From the point of view of the blast furnace plant structure itself, blast furnace, agglomeration processes, palletization processes or the processing of waste from production can be classified as emission points. The article deals with the classification of basic impacts of blast furnace production on the environment. It analyses in detail the negative externalities in ore sintering. It also deals with the analysis of research, which was focused on the degree of reduction of iron oxides ore. The efficiency of the reduction process is crucial in terms of resource use, but also the overall amount of negative externalities. The research was carried out in the environment of a selected iron producer in the Czech Republic.

The aim of the paper was to present the specificity of knowledge management in courier companies as an example of intelligent organizations. Knowledge management is a modern concept that emphasizes using the most valuable resources of enterprises such as employees and it offers conditions for development of knowledge, sharing it, and thinking creatively. The paper presents courier companies as an example of intelligent organizations that use knowledge management in the implementation of courier services. The article presents the results of a survey that identified the use of knowledge in courier companies and analysed the factors that made the surveyed companies become intelligent organizations. The solutions implemented in enterprises that influenced the emergence of a competitive advantage were evaluated. Furthermore, the benefits achieved by the companies surveyed due to knowledge management and the growth of their intelligence were analysed.
