Sažetak
In this study, a functional relationship between the solid particle density (ρs), void ratio (e), and dry density (ρd ) of mechanically and biologically treated (MBT) municipal solid waste (MSW)was examined. In total, 60 waste specimens were tested with an air pycnometer device and corre-sponding triplets (e, ρd, and ρs) of values were obtained. In addition, a long-term oedometer test withan allowed decomposition process was also conducted. Based on the obtained results, the variabilityin the solid particle density caused by heterogeneity and decomposition, as well as its influenceon the corresponding void ratio and dry density values, were critically evaluated. The obtainedresults showed that the variability in the solid particle density caused by waste heterogeneity had asignificant influence on the initial void ratio value. Furthermore, the obtained results also showed thatthe change in the solid particle density, caused by the degradation process, had a significant impacton the final void ratio and dry density values. In addition, an empirical relationship, ρd = f (e), was proposed. The proposed function allows a landfill operator to establish the corresponding drydensity at an arbitrary chosen void ratio, and vice versa, without having the exact knowledge of thecorresponding solid particle density value.
