Efficient strategies for reducing, reusing, and recycling waste generated by the hospitality industry activities [Articol]
(Universitatea de Stat din Moldova, 2024) Hămuraru, Maria; Perri, Antonella
The hospitality industry, as a rapidly growing sector, significantly contributes to global waste production, including organic materials, plastics, and construction waste. Addressing this environmental challenge requires effective strategies for reducing, reusing, and recycling waste. This paper explores innovative approaches to minimize waste production, such as sourcing sustainable materials, optimizing processes, and educating stakeholders. Reuse practices, including the adoption of reusable packaging, donation of surplus food, and water recirculation systems, are highlighted as key sustainable solutions. Additionally, recycling initiatives like composting organic waste, selective sorting, and collaborating with recycling firms are essential components of a circular economy model. Despite challenges such as high initial investments and the lack of clear regulations, integrating sustainable practices can enhance operational efficiency, reduce costs, and improve brand reputation. The study emphasizes that implementing green strategies not only mitigates environmental impact but also strengthens the competitive edge of hospitality businesses.
Particularitățile procesului logistic în serviciile ospitaliere [Articol]
(Universitatea de Stat din Moldova, 2024) Nazar, Nadejda
The paper describes the characteristic features of the development of the logistics process in hospitality companies. These features include the overall revitalization of business and the development of tourism. Due to the emerging need for people to satisfy their interests in understanding rural culture, a third feature, agritourism, has emerged. The logistics system of a hospitality company represents an essential component of its success and competitiveness. The logistics system operates on two levels—internal and external—and managing these is crucial for any tourism company. For these reasons, it is important to consider the logistics process activities in hotels and guesthouses to control the provision of services and monitor the effectiveness of their operations. In the activities of any tourism services, special attention is given to current legislation, international standards, and classifications from tourism organizations, which are also implemented in the tourism sector of the Republic of Moldova. In any activity, various problems or difficulties may arise (e.g., lack of professionalism among employees, requirements for service quality, absence of a communication system, etc.), and addressing these issues in a timely manner helps improve the services provided. To resolve challenges encountered in the logistics process of hospitality services, various methods are employed, such as administrative, organizational, economic, social-psychological methods, and others. In the activities of any operator, special attention is given to consumers, specifically tourists. It is worth noting that in recent years (2019–2023), the number of tourists visiting the Republic of Moldova has grown considerably. The logistics perspective allows for the reidentification of various hospitality services, ensuring the formation of their distinctive qualities and proposing advantageous characteristics compared to competitors.
Sustainable architecture and design in the hotel industry: combining aesthetics and energy efficiency [Articol]
(Universitatea de Stat din Moldova, 2024) Trifonova, Larisa
The latest trends in the hotel industry emphasize the importance of sustainability through the integration of aesthetics and energy efficiency into hotel architecture and design. This article explores modern methods and approaches to creating sustainable hotel facilities that not only impress with their design, but also minimize their negative environmental impact. It is noted that the efficient use of natural resources and the use of environmentally friendly materials are becoming increasingly priorities for architects and designers. The article examines examples of successful implementation of the concept of sustainability in the hotel industry around the world, and also discusses the benefits of such an approach for business, the environment and society as a whole. It also highlights the importance of collaboration between the hospitality industry, architects, designers and environmental experts to develop innovative solutions that contribute to the creation of sustainable and attractive hotel properties. The continued development of sustainable architecture and design in the hotel industry has the potential to change the landscape of the hotel industry, making it more environmentally responsible and socially conscious. Guests increasingly prioritize environmentally friendly hotels, driving up demand for sustainable accommodations. Such objects, in turn, receive competitive advantages and increase their attractiveness in the eyes of consumers.
Optimization of mass rearing technology of the entomophagous Bracon hebetor Say. under controlled laboratory conditions [Articol]
(Technical University of Moldova, 2026) Glibciuc, Corina; Nastas, Tudor
Background: The entomophagous Bracon hebetor Say (Hymenoptera: Braconidae) is a larval ectoparasitoid used as a biological control agent against lepidopteran pests of the Pyralidae family. Due to its high reproductive capacity and short ontogenetic development cycle, B. hebetor can be successfully multiplied under controlled laboratory conditions. Its mass rearing requires a viable susceptible host, such as Plodia interpunctella, which supports completion of the parasitoid life cycle. The larvae of P. interpunctella also allow evaluation of the biological and reproductive parameters of the entomophagous species. The aim of the present study was to optimize the multiplication technology of the entomophagous Bracon hebetor Say under controlled laboratory conditions, by estimating the influence of the host Plodia interpunctella on the biological and reproductive parameters of the parasitoid. Materials and methods: Larvae of the species Plodia interpunctella were reared on a nutrient medium of cornmeal, dried apple, glycerin and yeast. Controlled laboratory conditions of 27 ± 1°C and 65 ± 5% humidity ensured uniform development and reduced physiological variability. 24-hour-old adults of the entomophagous insect Bracon hebetor were used for infestation. 25 pairs were introduced into 1 L boxes with 25 host larvae, respecting the optimal parasitism density. The containers were covered with gauze and maintained in a 12:12 photoperiod environment. Monitoring was performed daily for parasitism. The experiment included three independent replicates, each with 10 experimental units. After 10–12 days, emerging imagoes were evaluated, determining the parasitism rate, development duration, and sex ratio (♀: ♂). Results: It was demonstrated that Plodia interpunctella larvae of III–V instars are optimal for the complete development of the entomophagous Bracon hebetor. The high parasitism rate indicates strong acceptability and trophic compatibility between parasitoid and host. Females of B. hebetor showed high reproductive potential, achieving on average up to 7 successive infestations during their life cycle. Total fecundity reached about 128 eggs per female, of which 122 larvae hatched (≈95.3%) and 115 reached the pupal stage (≈89.8%), reflecting high biological efficiency and offspring viability. Sex ratio analysis showed a predominance of males, with approximately 60.7% males and 39.3% females. The development cycle from egg to adult remained within species-specific limits and was strongly influenced by temperature (27 ± 1°C) and humidity (65 ± 5%). Maintaining these conditions ensured synchronized development and reduced mortality in immature stages, favoring the production of viable new generations. Conclusion: The species Plodia interpunctella represents a suitable and efficient host for the multiplication of the entomophagous Bracon hebetor under controlled laboratory conditions, ensuring complete development and major viability of the offspring.
