Article Fulltext (PDF), pp. 44–53: The environment gives a clear challenge to the inhabitants of the planet that it is necessary to reduce the amount of generated waste. Disposal, separation and processing of waste, or landfilling of produced waste is connected to processes that require additional financial resources. The main goal of the contribution was to analyze the differences in the amount of total produced waste, municipal solid waste, and separated waste in selected Slovak municipalities. The data were obtained by the questionnaire method from 33 municipalities in the Nitra region, which provided data on the amount and type of waste in the period 2015 - 2017. Selected statistical methods, paired t-test, analysis of variance and Bonferroni test were used to analyze the obtained data. The results of the analysis show that there are significant differences in the volume of waste generated by municipalities together between individual years. Similarly, statistically significant differences were demonstrated between the amount of produced waste in relation to the size of the municipality according to the number of inhabitants. In the evaluated period, medium-sized municipalities showed the lowest amount of produced waste per inhabitant.; Keywords: waste management, descriptive statistics, paired T-Test, analysis of variance, Bonferroni test; JEL Classification: C12, Q53
