“…Elements like copper, iron, zinc and rare earth metals are being depleted in their primary sources and there is an increasing demand on these elements due to the development of the standard of living (Jani, Marchand, & Hogland, 2014). As showed by previous studies (Quaghebeur et al, 2013), the fine fractions from landfill-mined waste might contain high concentrations of certain metals, offering attractiveness for feasible material recovery.…”

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.

“…Serious discussions regarding scarcity of important natural resources have been carried out throughout the world (European Commission, 2010). Natural constituents like copper, iron, zinc and the earth rare metals are depleted in their primary sources, while there is a huge increasing demand owing to the development of the standard of living (Jani et al, 2014). As an example, about 50% of the primary mined iron and copper are unusable now owing to landfilling and dumping in other waste streams (Krook and Baas, 2013).…”

The present research studies the characterisation and the physico-chemical properties of an excavated fine fraction (<10 mm) from a Swedish landfill, the Högbytorp. The results showed that the fine fraction represents 38% by mass of the total excavated wastes and it contains mainly soil-type materials and minerals. Higher concentrations of zinc, copper, barium and chromium were found with concentrations higher than the Swedish Environmental Protection Agency (EPA) for contaminated soil. The found moisture and organic contents of the fine fraction were 23.5% and 16.6%, respectively. The analysed calorific value (1.7 MJ kg), the potential of CH (4.74 m t dry matter) and Total Organic Carbon (TOC) (5.6%) were low and offer low potential of energy. Sieving the fine fraction further showed that 80% was smaller than 2 mm. The fine represents a major fraction at any landfill (40%-70%), therefore, characterising the properties of this fraction is essential to find the potential of reusing/recycling or safely redisposing.

“…Soil fraction from landfill is estimated to contain high heavy metals which can affect revegetation. To determine the quality of the landfill soil fraction and improve soil quality, it is necessary to conduct research on the effect of soil type and landfill soil fraction on plant growth [6], which in this study used mung bean (Vigna radiata L.).…”

One of the efforts to overcome the critical problem of land usage for landfill and regenerate waste is to reuse the expired landfill after managing them. The purpose of this study is to determine the potential utilization of waste from landfill mining activities. At 15 sample depth points in zone 1 of Sumur Batu Landfill from 2004-2007 waste, the composition of mining landfill waste consists of 29% soil/organic fraction; 25% other waste; 23% plastic; 11% overburden; 5% diaper waste; 2% cloth; 2% wood; 1% glass; 1% rubber; and 1% metal. The particle size of the landfill waste has a diameter distribution of >38.1 mm to <2mm which is almost evenly distributed with values ranging from 9-20%. The calorific value of combustible waste is 3, 569.47 kcal/kg. The chemical characteristics of the landfill soil mining fraction consisted of C-Organic 29.55%, NTK 0.65%, C/N 29.59, and Total-P 22.84%. Dosage variation of landfill mining soil fraction as a planting medium with soil used for research, respectively 1:4, 1:5, and 1:6, and soil with Bokham compost as control. The use of landfill soil fraction as a planting medium with 3 types of soil, namely clay, laterite, and acid clay causes a decrease in the growth of mung beans (Vignaradiata L.). However, the 1:4 landfill soil fraction dose gave a positive response to the physiological observations of plants compared to the other two doses of variation. The potential for landfill waste is 100, 000 tons, the total cost of landfill mining activities is Rp. 25, 829, 996, 775, and the total benefits of landfill mining activities are Rp.26, 347, 223, 544, with the use of combustible waste to produce electricity and/or heat using an incinerator, the benefit ratio value is 1.02 which is means that the activities of the Zone 1 of Sumur Batu Landfill is feasible to carry out. Based on these data, with organic waste as the dominant waste in the Sumur Batu Landfill, the best possibility in utilizing waste is to use the waste as soil fertilizer.
