The aim of this study was to examine the issue of waste collection from passenger ships in tourist port cities using the example of Świnoujście, Poland. This is an important issue from the perspective of sustainable development, including that of tourism, because an improperly organized waste collection process may endanger the natural environment and disrupt the life of the local community. After the analysis of the types of waste generated on vessels, the means of transport used for their collection were identified with particular regard to those used at the seaport in Świnoujście, a tourist city. The selected waste quantities collected from ships in 2017–2019 were quantitatively analyzed. In addition, the number of waste collections was analyzed in the context of the number of vehicles involved in this process. The latter element is important in terms of impact on the port city’s transport system, which has a spa and tourist function.
