Sustainability is currently one of the major priorities of tourism all over the world. This paper deals with applying elements of green management in accommodation facilities in the city of Sofia, Bulgaria. It analyses the implementation of green management elements and the principles of sustainable development in accommodation services. It focuses on accommodation facilities and their use, and environmental measures. The primary survey was conducted from May until June 2018 and we used a questionnaire survey to obtain primary data. We used the methods of scientific work; and, i.e., the analysis method, a generalization method, mathematical, and statistical methods. A total of 96 accommodation facilities participated in this research and they reached the best results with sorting containers, dual flush toilets, compact fluorescent lamps, and LED lamps. We state that the surveyed accommodation facilities should invest more funds in green initiatives and acquaint employees and guests with this philosophy.

The research in textiles is being driven by ecology, economy, and functionality. Therefore, the present research is focused on the development of multifunctional textiles that consume minimum energy during their processing, eco-friendly chemicals for functionalization, and use short processing steps. Eco-friendly cross-linkers such as butanetetracarboxylic acid and zinc oxide nanoparticles are used to impart wrinkle recovery, antibacterial activity, ultraviolet (UV) protection, bending rigidity, and antistatic properties to cotton fabric just in one step. The treated fabric has been characterized with Fourier-transform infrared spectrophotometer, scanning electron microscope, and X-ray diffractometer. Wrinkle recovery, tear strength, antibacterial activity, UV protection, and antistatic properties were tested with AATCC 66-1990, ASTM D 1224, AATCC 147, AATCC 183, and UNI EN 1149, respectively. The treated fabric shows excellent functional properties up to 20 washing cycles.

The paper is devoted to the applications possibilities of heat pipe in heat recovery installations. It was presented selection of optimal working fluid which can work at wide range of temperature, showed the threats arising with used flammable, toxic and harmful to the environment substances. In the paper showed the possibilities of use a new generation of environmental friendly fluids. At the end the article shows the structure and principle of operation a test right which will be use to research at effectiveness of heat pipe work with some selected fluids.

Artykuł poświęcony jest możliwością aplikacyjnym rurki ciepła w instalacjach odzysku ciepła. Zaprezentowano dobór optymalnego czynnika roboczego mającego pracować w szerokim zakresie temperatur roboczych. Scharakteryzowano zagrożenia wynikające z wykorzystywania substancji łatwopalnych i toksycznych oraz szkodliwych dla środowiska naturalnego. Pokazano możliwości jakie niesie ze sobą pojawienie się nowych proekologicznych substancji roboczych, dedykowanych aplikacjom energetycznym. Przedstawiono budowę oraz zasadę działania układu pomiarowego mającego służyć badaniom efektywności rurki ciepła pracującej z różnymi czynnikami roboczymi.
