Abstract

This study presents the results of investigation of the fine waste fraction from the Alytus Regional Landfill. The fine fraction was analysed with the aim of characterization of the chemical elements content using scanning electron microscopy, coupled with energy-dispersive spectroscopy (EDS), SEM and X-ray diffraction (XRD) analysis. Quartz SiO₂, calcite CaCO₃, anhydrite CaSO₄, albite NaAlSi₃O₈, dolomite CaMg(CO₃)₂, microcline KAlSi₃O₈, periclase MgO and muscovite KNa(Al, Mg, Fe)₂(Si_3.1, Al_0.9)O₁₀(OH)₂ minerals were identified. The quantity of C, O, Na, Mg, Al, Si, K, Ca, Fe, P, S, Cl and Ti chemical elements was determined and their percentage change after heating was calculated.
