Waste physico-chemical characteristics and the presence and availability of three metals (As, Cu and Pb) in a glassworks dumpsite were investigated to assess excavated waste handling and storage requirements pre-valorisation. Eight 2 m deep test pits (TPs) were excavated and sampled at 0.5 m depth intervals. The excavated waste was hand-sorted, followed by X-Ray Fluorescence (XRF) scanning, leaching and HNO₃ digestion of the fine fraction (< 10 mm), and assessing results against Swedish EPA regulations. The waste composition was glass > inert > organic > “other” waste, whereas the total metal concentrations (XRF) were Pb > As > Cu. Pb (all TPs) and As (four TPs) were in hazardous levels whereas Cu was not. TDS (2856 ± 467 mg kg^-1) and DOC (56.4 ± 21.8 mg kg^-1) were lower than the inert, non-hazardous and hazardous waste storage thresholds, whereas F^- (10.8 ± 2 mg kg^-1) was higher than the inert waste storage threshold. Moisture content was 24.4 ± 11.4% while pH was 7.3 ± 0.8. Leached metal concentrations were Pb > As > Cu, with low metal leachability (0.02% - 0.2%), and the leached amounts were lower than the non-hazardous and hazardous waste storage thresholds, but higher than the inert waste storage thresholds. HNO₃ digestion yielded As and Cu concentrations higher than the thresholds for sensitive and less sensitive land uses, and Pb concentrations higher than the non-hazardous waste storage threshold. Metal recovery was 49.3%, 44.2% and 17.9% for Cu, Pb and As respectively. Although the waste was hazardous in nature based on total metal concentrations and Pb concentrations from acid digestion, the leaching was not in hazardous levels due to strongly bound metals in the waste material.
