Decomposition analyses of the municipal waste generation and management in Croatian and Slovenian regions

The purpose of this study is to analyse how much waste generation activity influenced the amounts of waste which were sent for recovery or landfilling in Croatian and Slovenian regions for the period 2010–2014. The analyses were conducted by applying two variations of logarithmic mean Divisia index analysis model: (1) one covering the economic activity which generates waste (household consumption) and (2) the second one covering the waste generation activity itself. By applying a novelty approach the results of these two models were combined to present the information more clearly. The municipal waste streams analysed were: paper, plastics, metal, glass, bulky waste, textile, bio-waste and mixed municipal waste. The results for both countries show that the waste generation as an activity did not have the dominant effect on the amounts of waste sent for recovery in all of the observed periods. In the case of waste sent for landfilling the results for Slovenia are the same; however, the results for Croatia show that the activity which generates waste had the dominant influence in most of the periods analysed caused by the fact that in average 93% of the municipal waste generated per year was sent to landfill.
