N2 - Within the framework of the “EU Training Network for Resource Recovery through Enhanced Landfill Mining – NEW-MINE”, around 371 Mg of waste were excavated from a landfill site in Mont-Saint-Guibert, Belgium. Parameters such as bulk density, water content, particle size distribution and material composition of the fine fractions (material <90 mm) were determined and analyzed. The variations of bulk density and water content with particle size were studied as well and grouped material fractions were employed for the classification of the material composition. The present article has the main objective to document and disseminate the findings on the material characterization of the fine fractions obtained in this case study, since such information is of critical relevance for the design of an effective and efficient mechanical processing in (enhanced) landfill mining projects. Additionally, the potential of fine fractions for material and energy recovery is discussed. The fine fractions accounted for about 77 wt.% of the total amount of excavated material in raw state. These fractions presented an overall bulk density range of 720-1000 kg/m3 (raw state) and a total water content range of 25-30 wt.%. Results on the material composition in dry state reveal that amounts of 2.1-19.7 wt.% “Combustibles”, 31.1-35.4 wt.% “Inert” and 0.6-1.8 wt.% “Total metals” could be recovered from fine fractions 90-10 mm, while 37.8-55.6 wt.% “Fine fractions <10 mm” could be processed further in order to increase the recovery amounts of the previous fractions and produce a soil substitute material.
