Landfills have been identified as potential sources of heavy metal pollution of the environment. The municipal solid waste Łubna landfill is one of the largest landfills in Poland. Its impact on heavy metal pollution (Cd, Pb, Zn, Cu, and Cr) of groundwater, soil and plants has been thoroughly evaluated. Elevated levels of contamination have not been recorded in the vicinity of the landfill. The concentrations of heavy metals in soil from the vicinity of the landfill were similar to the geochemical background levels for the forest and farming soils of central Poland. The concentrations of heavy metals in European goldenrod (Solidago virgaurea L.) and grasses (Poaceae) did not exceed the baseline concentrations and did not indicate environmental pollution by heavy metals. The levels of the metal concentration in groundwater did not exceed the standards established for water intended for consumption.

“…Thus, landfills are increasingly seen as 'local mines' where valuable products were accumulated over time and thus excluded from further processing. When metal-containing waste is landfilled on a heap, metal mobility is limited (Jain et al 2005). In case of metallurgical slags, a pH is ca 11 restricts the mobility and leaching of elements (Bozkurt et al 1999).…”

Abstract. The recovery of valuable metals from metallurgical slag disposals is a promising option to protect natural resources, limited due to technology development and increased consumption. The Ad-hoc Working Group on Defining Critical Raw Materials within the Raw Materials Supply Group has proposed a list of critical elements which have the greatest economic importance and meet the requirements of sustainable development in Europe. The goal of this study was to examine steelmaking-and blast-furnace slags from metallurgical processes to determine concentrations of elements of the greatest criticality for Poland, e.g. Nb, Ta and REE, and to discuss the viability of their recovery. Slag analyses indicate enrichment of REE relative to UCC, NASC and average chondrite compositions in blast-furnace slags and Nb and Ta in steelmaking slags. To make recovery of these critical elements reasonable and profitable, it is recommended that they be recovered together with other useful raw materials.

“…Different landfill mining characterization studies havefocused on the screening of the waste to different particle sizes followed by hand sorting of the coarse fraction [7,8,11,12]. Hogland [7] studied the characterization of the Måsalycke landfill which is located in the southeastern part of Sweden.…”

“…The results showed that 50% of the coarse fraction (>50 mm) was wood and paper, the medium size fraction (18-50 mm) contained stones and soil like material, and the fine fraction (<18 mm) contained peat like material. Hull et al [11] studied the characterization of excavated waste materials from the Burlington County landfill in New Jersey in the northeastern USA. The waste material was screened to two fractions: a fine fraction and coarser oversized fraction (>25.4 mm).…”

A B S T R A C TLandfills represent a continuous environmental threat due to the emission of different greenhouse gases, which are mainly responsible for the climate changes, and the contaminated leachate that affects the surface and ground water recipients. The circular economy approach appeared as a useful solution to reduce the depletion of the Earth's natural resources and the environmental risk effects by considering all of the lost resources like wastes including the landfills as potential secondary resources. It is well known that characterizing the composition of landfill waste is an essential step in specifying the recycling methods. In the current research the waste composition at one of the first EU regulationscompliant sanitary landfills (the Torma landfill in Estonia) was studied. The results showed that the fine fraction (<20 mm) represented 53% of the total excavated waste materials while the waste to energy fraction (plastics, woods etc.) was the highest within the coarse fraction (>20 mm). The present work emphasized that mining landfills can be a good solution either for extracting primary raw materials like metals, as a source for recovering energy, or for acquiring landfill space.
