The impact of TOURISM and seasonality on different types of municipal solid waste (MSW) generation: The case of Ibiza

Most studies analysing waste generation consider the impact on the resident population; however, in the case of tourist destinations, it is important to differentiate the impact between the local population and tourists. This research separates these two population groups using the stochastic impacts by regression on population, affluence and technology (STIRPAT) model for the case of Ibiza. The results confirm different waste generation patterns in tourist and non-tourist populations depending on the waste type (non-sorted and sorted). Moreover, our analysis found that the amount of waste generated per person decreased over time, demonstrating the growth of circular economy practices in the destination. Furthermore, the STIRPAT model highlights the development of a circular economy, showing a downward trend in the generation of non-sorted waste and a positive trend towards collecting recyclable materials. Finally, the results confirm that waste generation patterns vary by season, population, and waste type. Additionally, for both populations, there is a reduction in per capita non-sorted waste generation (this is more significant for the non-tourist population). In contrast, per capita sorted waste generation has increased for both types of population.
