Abstract [en]
The ‘Glasriket’ of Sweden’s Småland region is characterized by an array of landfillsand dumpsites of glass and other raw material wastes from old glassworks. Most ofthe dumpsites contain heavy metals with leaching capabilities to soil and groundwater. As these metals could be potential resources that could be recovered into theresource loop, the characterization of these wastes can provide necessary informationabout the resource recovery potential. The current investigation focuses on the firststages by quantifying the amounts of selected metals (Ba, Cr and Zn) in the glassdeposit at Madesjö dumpsite as a case. The dump was sampled at nine different pointsand two levels per point. The samples were subjected to X-ray Fluorescence scanning(XRF) and leaching tests with further analyses of metals using ICP. According to theinvestigation, the highest metal contents in the solid phase were observed in Zn(average of 4515 mg/kg) while the lowest were observed in Cr (average of 72 mg/kg).In the liquid phase, the average metal concentrations were observed to be 0.37 mg/kg,0.02 mg/kg and 0.23 mg/kg for Ba, Cr and Zn respectively. These, however, are not inreadily available form, and so further investigations need to be done in order to findcost-effective techniques for their extraction. On the other hand, further investigationsneed to be done to ascertain the leaching potential by altering such leachingparameters as contact time and liquid to solid ratio.
