“…Comparing hotels and guesthouses found similar values for waste separation (89% vs. 88%). However, it should be noted that more hotels and guesthouses should have separated waste as it is a legal obligation, see also [ 76 , 82 , 89 ]. Roughly every fifth hotel and guest house separated biological waste.…”

The economic recovery of the tourism industry after the Covid-19 pandemic to find modern and efficient trends to increase profitability is accompanied by the adoption of comprehensive accommodation approaches towards resilience and environmental sustainability. The research aims at the application of environmental management elements and measures in all types of accommodation facilities in the Czech Republic (n1 = 1,016). A qualitative focus group method complemented the quantitative research using correspondence analysis, Levene’s, Kruskal-Wallis, and Tukey’s HSD tests (n2 = 9 + moderator). The results indicate that the differences in the number of environmental measures implemented were minimal for the monitored hotels and guesthouses. On the other hand, the star rating of accommodation facilities is not a key parameter in the environmental impact assessment. The most used environmental measures were devices reducing electricity consumption (hotels 94%, guesthouses 94%), separating waste (hotels 88%, guesthouses 89%), and water consumption reduction (hotels 85%, guesthouses 86%). At the same time, the most minor used were measures reducing chemical consumption (hotels 23%, guesthouses 22%) communication and environmental education of employees and guests (hotels 32%, guesthouses 18%).

In recent years, the importance of sustainability and circularity in waste management systems has become increasingly evident. As the world grapples with the environmental consequences of excessive waste generation, it has become crucial to find innovative and sustainable solutions. Universities, as centres of knowledge and research, play a vital role in achieving sustainability and circularity in waste management. The key contribution of this study is to provide: 1) a systematic review of the existing literature concerning sustainable waste management systems (SWMS) implemented in universities; 2) an analysis of the studies presented in this paper identifying applicable approaches and sustainable practices to provide novel guidelines by including waste management system in a circular and sustainable model within universities. Through research, collaboration, education, implementation of sustainable practices, and support for entrepreneurship, universities can strongly contribute to the development and implementation of sustainable waste management practices. As the world continues to face the challenges of waste generation, universities will continue to be at the forefront of finding innovative, sustainable, and circular solutions.

The concept of the circular economy represents the most relevant mainstream approach to reducing the negative environmental impact of waste. Anaerobic digestion has proved to be one of the leading and widely adopted techniques for sewage sludge treatment under the principles of the circular economy. The purpose of this study is to forecast environmental and economic indicators through modeling the extensive utilization of biogas technologies with a case study of an administrative territorial unit. The proposed methodological framework involves the use of averaged specific indicators and is based on the relationship between inhabitants, waste generation rates, biogas yield, greenhouse gas emission mitigation and biogas energy potential. The widespread use of anaerobic digestion techniques according to the proposed methodology in the instant scenario will ensure the biogas yield of 10 million Nm3 within the considered administrative territory unit with a population of 4.2 million P.E., which ultimately can be expressed in electricity and thermal generation potential of 20.8 and 24.8 million kWh*y, respectively, annual greenhouse gas elimination of 119.6 thousand tons of CO2 equivalent and capital investment attraction of EUR 65.18 million. Furthermore, all sewage sludge will be subjected to disinfection and stabilization procedures to ensure its safe utilization. The findings of this study offer an opportunity for a wide range of stakeholders to assess the environmental and economic benefits of the widespread adoption of biogas technologies. The developed methodology can be utilized to inform management decisions through the use of the instant and scenario forecasts.
