“…According to previous investigations (Kaartinen et al, 2013;Mönkäre et al, 2016;Wolfsberger et al, 2015) the amount of fines to be obtained in a LFM project mostly depends on the excavation procedure, the age of the waste and the selected cut-off diameter to define a certain particle size as upper limit for the fine fractions. For example: (i) the implementation of borehole sampling via drilling activities can increase the amount of fine fractions in the samples, (ii) the amount of fine fractions has been found to raise with age in some investigations and (iii) the amount of material passing the screen tends to increase with the increase in size of the cut-off diameter of the screen.…”

“…Additionally, the characteristics of the fine fractions of landfill-mined material can be influenced by the chosen processing, e. g. sieve size affects utilization and disposal methods of the sieved materials, as it has been observed that the methane potential rises with the increase of particle size (Mönkäre et al, 2016). Moreover, the amount of fine fractions increases with time due to the decomposition processes (Jani et al, 2016).…”

“…Because of the lack of economic value, the characterization properties of the fine fractions have not been thoroughly investigated (Mönkäre et al, 2016). Nonetheless, in order to evaluate the specific recycling potential of a landfill, adequate and proper quantitative and qualitative characterizations of the disposed waste are to be performed (Prechthai et al, 2008).…”

“…Fine fractions (frequently defined as material with a particle size < 60 mm to < 10 mm) account for 40-80 wt.% of the mined material in previous studies (Hogland, 2002;Masi, Caniani, Grieco, Lioi, & Mancini, 2014;Kaartinen et al, 2013;Kurian, Esakku, Palanivelu, & Selvam, 2003;Rettenberger, 2009;Hull et al, 2005;Mönkäre, Palmroth, & Rintala, 2016;Quaghebeur et al, 2013;Maul & Pretz, 2016;Van Vossen & Prent, 2011;Wiemer, Bartsch, & Schmeisky, 2009;Wolfsberger et al, 2015). Therefore, regardless of the particle size used to define the fine fractions, its quantity will always be an important factor to be considered in LFM and ELFM projects.…”

Characterization of Fine Fractions From Landfill Mining: A Review of Previous Investigations

Several landfill mining (LFM) studies have been carried out in recent years all around the world. From these studies qualitative and quantitative information regarding the composition and characteristics of the different fractions excavated from landfills has been obtained. This information comprises data from various landfill sites around the globe from which useful correlations for future LFM projects can be identified. Of particular interest to this paper is the information regarding the fine fractions, which represent to this day a crucial obstacle in the implementation of LFM and enhanced landfill mining (ELFM). The fine fractions make up a considerable portion of the total amount of waste disposed of in landfills. Depending on the particle size chosen as upper limit to define the fines fraction, the portion of this fraction can be as high as 40-80 wt.% of the total excavated waste. These fractions consist of decomposed organic substances, e.g. humic substances, partly weathered mineral waste, e.g. sand, brick fragments, concrete, but also of fine metal particles, especially non-ferrous metals, and still a significant amount of plastics, paper and other calorific fractions. However, although calorific fractions might be used for energy recovery and inorganic fractions for material (especially metal) recovery, current LFM studies are discarding the fine fraction due to lacking or too expensive processing routes. Therefore, it is of critical interest to LFM and ELFM projects to reduce the particle size down to which the excavated material can be processed. This paper, which was elaborated within the framework of the EU Training Network for Resource Recovery through Enhanced Landfill Mining -NEW-MINE, aims to review the obtained data from different LFM studies from municipal solid waste (MSW) landfills, concerning the fines fraction, in order to identify key aspects to be taken into consideration while designing the processing approach in future LFM and ELFM investigations.

“…Mining does not only enable the recovery of valuable materials but also allows for the recovery of land area, The excavation of landfills is supposed to take place after the end of the aftercare period, taking into account the desirable aeration. Excavated materials are sieved to fine (<20 mm) [22] and coarse (>20 mm) fractions. The fine fraction is backfilled.…”

Proposal for Feasibility Assessment Model for Landfill Mining and Its Implementation for Energy Generation Scenarios

New approaches to waste management and requirements of a circular economy have changed landfill management. Therefore, the updating on these subjects is required. To benefit from landfill mining, information about composition and properties of disposed waste should be gathered. Decay of landfilled waste over time primarily determines the amount of recyclable and combustible matter as well as the amount of landfill gas formation. In this paper, we propose scenarios for landfill management and we create a conceptual model on their basis. A conceptual model is formulated and theoretical calculations are performed and compared with field research results in order to understand changes in the composition of landfilled waste. Correlations between theoretical and actual results were determined. Correlations of theoretical and actual results for the Torma (EE) and Alytus (LT) landfills were 0.68 and 0.78, respectively. In addition, the changes of refuse-derived fuel resources in Alytus landfill during the previous 10-year period were calculated. Finally, four different landfill closure and aftercare scenarios with respect to energy generation were created, assessed, and compared.
