Zero waste according to the Zero Waste International Alliance is an ethical, economical, effective and forward-thinking concept whereby people can change their lifestyles and habits to one that mimics natural cycles, where all discarded materials are designed to become resources that can benefit others. The aim of the study was to determine the knowledge of the Zero Waste problem (subject of the study) by respondents in selected Central and Eastern European countries, including Poland, Slovakia (EU countries) and Ukraine (EU associated country), as well as to verify whether the Zero Waste rules are known and implemented in sustainable activities of residents in the studied countries. The research was carried out using the CAWI method. The research tool was a structured questionnaire. The analysis of data from the countries covered by the study showed a significant relationship between the basic elements in the daily functioning of households related to the protection of the environment through responsible consumption, reuse and recovery of selected products, packaging and materials and food and the concept of Zero Waste. Research has shown that respondents consciously identify these activities with Zero Waste. According to the authors, the results of the research are the basis for public discussion at the European and global level in the field of creating legal regulations and educational programs in the context of waste management.

The level of agricultural development in European Union countries is characterized by great diversity. This is due to differences in natural conditions, the type of agricultural production, agrarian fragmentation, and the level of economic development. The concept of a circular economy is the latest vision of changing the current economic systems, the assumptions of which constitute an alternative to the linear model of resource use. The implementation of the principles of a circular economy aims to create a system that will contribute to the implementation of sustainable development. This could be a strategy to support agriculture in the absence of agricultural land and water resources. This research aimed to identify and assess the spatial diversification of agricultural production-economic conditions and their links with the circular economy at the level of EU countries. The basis for grouping countries was synthetic measures obtained in the areas of agriculture and the circular economy. The analyses were performed for 2012 and 2020. The obtained results indicate the existence of significant spatial dependencies in the development of agriculture and the circular economy. Countries with a higher level of agricultural development were also higher in the ranking of the advancement of the implementation of the circular economy concept.

The actions, decisions and behavior of consumers in a circular economy are defined as a circular consumption system. The circular economy is an alternative economic model to the linear model of production and consumption. This model is in line with the zero waste concept, which according to the Zero Waste International Alliance, is an ethical, economical, efficient and forward-looking concept in which consumer behavior includes buying products, caring for them and then recycling or reusing them. This is closely linked to adopting and committing to the circular business model of extending and reusing products. The aim of the study was to identify and describe consumer behavior and activities related to the zero waste concept. The analysis was conducted in the context of reusable products. The research was based on the CAWI method. The tool used to obtain the information was a structured questionnaire. The survey included 821 respondents from Poland, Slovakia and Ukraine. The survey shows that consumers are becoming increasingly aware of the consequences of consumption not based on choices with a positive attitude towards the environment. In addition, consumer sensitivity to environmental problems is growing. Growing consumer awareness and the promotion of healthy lifestyles by environmental organizations and movements are reversing unfavorable trends in favor of conscious consumption based on rational consumer choices, which translates into economic effects for households. The study found that the behavior of many respondents fits into the zero waste concept, implementing habits on a daily basis that are in line with sustainable consumption.

Consumers' buying behavior and preferences are affected by many factors such as the product quality, price, labeling and country of origin. The objective of this paper was to examine the opinions of the Slovak consumers about the purchase and consumption of eggs and identify their preferences at egg purchase. The input data were obtained using a questionnaire survey. The method of descriptive statistics and selected methods of measuring dependence or associations were used. The existence of statistically significant relationships was verified by the Pearson chi-square test or by the Fisher's exact test. The statistical proof of relationships was evaluated based on the significance of the test characteristic (p-value). The existence of dependence between the most important factor affecting purchasing of eggs - a price of eggs, and the age of the respondent - was confirmed. Further, the relationship between the preferred place of buying eggs and the classification criterion was also proved, i.e. whether a respondent is a breeder of the egg type of hens or not. The relationship between the preferred place of buying eggs and the gender of a respondent was confirmed as well. There was determined the dependence on the gender of a respondent in the question related to eggs consumption.
