Paper presents results of qualitative part of a broader research conducted in the field of municipal solid waste management in South Moravian Region in the Czech Republic. Preliminary efficiencies of municipalities in solid waste management were calculated using Data Envelopment Analysis with data about solid waste generation, municipal population and relevant municipal expenditures. Interviews regarding municipal waste management attributes were conducted with relevant responsible municipal authorities from selected sample of municipalities. Acquired data were compared with results of calculated municipal efficiencies in a set of correlation analyses. Results from examined sample show that more efficient municipalities are likely to be smaller in terms of population, have less frequent solid waste collection, use landfills for solid waste treatment, and have lower amount of "separation nests". On the other hand, having larger share of people living in flats, and using incinerator for solid waste treatment is more common among less efficient municipalities. Presence of more competitive environment, public or private ownership of company providing municipal solid waste management, or the level of fee per capita for waste collection and treatment in examined sample does not seem to be connected with either higher or lower efficiency of municipalities in this field.
