Opis:
Customers are more and more deciding to use various types of services via Internet. They make very often different types of purchases. E-commerce is becoming more and more popular and developed. Unfortunately, according to customers, online shopping is not free from problems. Customers are afraid that the ordered goods will not be sent to them, will not meet their expectations, or will be destroyed during transport. An important aspect is also the payment method for this type of shopping. Customers often prefer to pay more to use the option of payment on delivery to avoid losing money if the ordered goods do not be delivered to them. The purpose of the paper is to analyze the safety of services offered via Internet. In the research the customers of different e-shops expressed their opinion on problems that may affect the safety of the offered services. Thanks to the research, it was possible to identify risk areas in accordance with the opinion of customers.

Opis:
Steel is currently main structural material in the world. Pig iron, which is the basic product of blast furnace process, is the semi-product used in steel-making processes. It is an alloy of iron with carbon containing above 2% C and other elements with limited content, intended for further processing. Chemical composition of pig iron is its basic quality factor, it defines its class and meeting requirements set by steel plant department. It is important that this chemical composition is as stable as possible. In addition, the temperature of pig iron is also very important quality parameter. The paper presents statistical analysis of quality parameters of pig iron produced in one of Polish steelworks. The content of alloying elements and temperature of tapping of pig iron from blast furnace were examined. The amount of non-conforming production and the losses related to the low quality were assessed.

Opis:
The enrichment of the society and the consumptive lifestyle caused that customers buy more and more, having different, often very high requirements as to the purchased products and services. They often do not realize that production of such products requires more and more materials, energy and other means of production. All this leads to high exploitation of the environment. Even if the resources of the natural environment are not exhaustible, they do not keep up with their rebuilding at this pace of exploitation. That is why social awareness and responsibility both of producers and customers play such an important role. They are one of the instruments needed to operate in accordance with the concept of sustainable development. The aim of the research was to examine social awareness and responsibility among customers of service enterprises. The research was conducted with the use of an online survey, which allowed to show whether the customers of such enterprises are interested in the concept of the sustainable development, if they take it into account when using various services. The need for environmental education was indicated, which could strengthen the social awareness and responsibility among Polish customers.

Opis:
The manuscript explores the feasibility of recovering zinc and iron from waste galvanic sludge generated during galvanic plating processes. Galvanic sludge, characterized by elevated concentrations of heavy metals, represents a suitable candidate for hydrometallurgical recycling. The primary objective of the experimental and practical phases was to extract zinc and iron through the leaching of galvanic sludge. Leaching procedures were conducted using sulfuric acid at varying temperatures and time durations, augmented by the introduction of oxidizing agents such as hydrogen peroxide or ozone. Subsequent separation of the leach and filtrate was achieved through filtration. The leachate underwent additional processing involving the precipitation of iron and other metals, employing diverse agents. Following further filtration, electrolysis was employed to attain pure zinc on the cathode, utilizing an electrical voltage of approximately 3 V. Comprehensive chemical analyses were conducted on all intermediate products, including the leachate, leach liquor, filtrate, solid precipitate, and the separated metal on the cathode. The outcomes of these analyses are meticulously presented in tables and graphs.
