Poland’s management of municipal waste, which amounts to over 13 million tons/year, is not efficient—about 60% of the waste is subjected to recovery processes, about 20% of all municipal waste is converted into energy, and almost 40% is landfilled. The authors of this article recognize the potential of pyrolysis as a method of the thermal processing of waste allowing the potential of the energy contained in the waste to be utilized. Pyrolysis is an economically attractive alternative to incineration, with a significantly lower environmental impact, allowing efficient waste management and the use of pyrolysis by-products in the energy sector (pyrolysis gas), or in the building materials sector (biochar). Despite so many advantages, this method is not employed in Poland. The aim of the paper is to indicate a recommended strategy for the application of pyrolysis in Poland as a method of the thermal processing of municipal solid waste. SWOT (strengths, weaknesses, opportunities, threats) analysis was used as a research method. In the first step, on the basis of the literature review, the factors which may affect the use of pyrolysis in Poland were identified. In the second step, five experts evaluated the weights of those factors and the interactions between them. The products of the weights and interactions allowed, in accordance with SWOT analysis methodology, the most desirable strategy of pyrolysis application in Poland to be determined, which turned out to be an aggressive one. This means that pyrolysis as a thermal waste processing method should be implemented on a large scale in Poland to improve the indicators of municipal waste management.

Social media-especially for young generation Z-have become an essential tool for establishing private, professional and consumer relations. People from generation Z constitute an increasingly demanding group of customers. The aim of the paper is to find out how representatives of generation Z assess the creation of a company profile by an enterprise on social media, and to indicate the actions taken by an enterprise on its social media company profile that had the biggest impact on representatives of generation Z's decisions to make a purchase. As well as literature review, a survey was conducted among 233 students-representatives of generation Z. Analysis of the gathered empirical data gave grounds for verifying the research hypotheses formulated in the paper and concluding that most of the surveyed representatives of generation Z consider a company profile to be a valuable source of information about the company and its offer. Moreover, actions taken by entrepreneurs on their company profiles impact purchasing decisions of representatives of generation Z. Actions with the biggest impact on their purchasing decisions include: publishing information about promotion and receipt of a discount coupon. Additionally, the strength of the relationships between the analysed variables and the respondent's gender and place of residence was verified.

Building relationships with Generation Z on social media is becoming a challenge for present-day enterprises. The aim of the paper is to indicate the features of the activity of the representatives of generation Z in social media that enable the company to build relationships in order to achieve benefits.The study of Generation Z behaviour towards brands on social media is part of broader research conducted by the authors among students in Poland and Great Britain in 2020. The method used in the study was a survey, as part of which the CATI surveying technique was used. For analysis of the study material, descriptive statistics measures were used. The findings show which social networking portals are most often used by respondents of Generation Z, what benefits they then expect and what actions they perform most often when communicating with businesses on social media. Additionally, the strength of the relationships between the analysed variables and the respondent's gender was verified.

Streszczenie: Zmiany demogra czne skutkujące starzeniem się ludności powodują poszukiwanie rozwiązań, które zaowocują przedłużaniem aktywności zawodowej człowieka. Celem niniejszego opracowania jest przedstawienie procesu starzenia się zasobów pracy w Polsce oraz wskazanie roli strategii zarządzania wiekiem dla łagodzenia jego skutków. Autorzy postawili tezę badawczą, iż zarządzanie wiekiem w organizacjach może być narzędziem pozwalającym upowszechniać wiedzę na temat zagadnień związanych ze starzeniem się pracowników w kontekście pogłębiającego się Zeszyty Naukowe Wyższej Szkoły Humanitas. Zarządzanie 424 procesu starzenia się populacji Polski. Analiza danych empirycznych ukazuje narastający kryzys demogra czny w Polsce. Starzenie się ludności to proces nieuchronny, a sprostanie mu wymaga podjęcia działań o charakterze systemowym w zakresie działań aktywizacyjnych na rynku pracy.
