The dynamics of economic development determines the need to develop technologies for waste recycling especially the acquisition of condensed fuels for the needs of the local diversification of energy sources. In a short time, Poland will probably lack its own produced electricity. To apply the process of diversification of energy sources, by developing methods of generating energy from waste, it becomes crucial to protect the environment. The use of cogeneration technology based on fuels derived from waste, in particular concentrated oil and gas fuels, is becoming more common and provides the basis for securing the energy supply in the preferred diversification process. Plastic waste processing in the controlled depolymerization process, which is the reverse of the polymerization process for hydrocarbon recovery – uses petroleum derivatives its production. At present, the greatest interest arises in the material recovery of plastics and rubber in the process of anaerobic thermal decomposition (thermolysis/pyrolysis), which is used on an industrial scale and consists in the degradation of polymer bonds into low molecular weight. The imperative of a modern economy is to obtain energy from fuels from waste treatment, including hazardous waste, preferably in the cogeneration process. The fuel obtained from waste may be used to obtain thermal or electric energy in order to diversify energy sources. The article presents innovative Polish technologies of obtaining fuel in processes of anaerobic thermal decomposition mainly of elastomeric and polymeric waste (including hazardous ones) for direct application in power generators of various power.

The problem of regional diversity is the subject of a broad scientific discourse. The dynamics of territory development is connected with many factors. Among them, the so-called spaces for development opportunities of individual units and resiliance issues for external factors of regions. The author discusses the diversity of individuals from the point of view of these two factors. It indicates future directions of regional research, which will show why regions at the start with potentially the same structure are developing completely differently and why in most cases resistance is associated with innovation and in the case of Polish regions it is not.

Following G. Bellmann, the article divides the German loanwords in Czech and Slovak roughly into two groups, namely those lexical units that represent a basic code extension (= type A) and those that are used immediately after adoption as (approximately) synonymous lexical duplicates of already existing designations (= type B). While type A words have the best chances of lasting integration, type B words elicit a competitive situation between old and new designations, which can result in substitution, negative integration or semantic diversification. Furthermore, the paper deals with idiosyncrasies of German loanword integration such as the expressiveness of German loanwords in Czech and Slovak and the emotional attitude towards German loanwords in those languages. The article also discusses the causality of displacement and substitution of German loanwords, subsequently elaborates on the loss of terms and realities, the change in domain-specific language use, the role of language awareness and language culture, the loss of immediate contact areas as well as the question of prestige, and concludes with an outlook on future developments.
