“…The nutrient contents were low for two observed landfills; especially total phosphorus was below detection limit of 10 mg/kg (dry matter) in most sampling points (Mönkäre et al, 2016 for nitrogen content reported by Riber, Petersen, & Christensen, 2009 were significantly higher than the ones from landfilled material reported by Hogland et al, 2004 andMönkäre et al, 2016. This reflects the consumption and migration of the nutrient content in the fine fractions after disposal.…”

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.

Influence of Income Level and Seasons on Quantity and Composition of Municipal Solid Waste: A Case Study of the Capital City of Pakistan

et al. 2017

Abstract:The current study aims to analyze and compare the quantity and composition of municipal solid waste (MSW) at three socio-economic levels of population during all four seasons of the year (spring, summer, monsoon and winter). In this study, 2164.75 kg of MSW was evaluated, from 1260 samples collected from 45 households. The average waste generation was estimated to be 0.6 kg per capita per day. Waste generation rate for high, middle and low income groups was 0.890, 0.612 and 0.346 kg per capita per day, respectively. Nevertheless, season specific analysis indicated waste generation rates of 0.78, 0.58, 0.48 and 0.75 kg per capita per day in spring, summer, monsoon and winter, respectively. A two way ANOVA statistical analysis further illustrated a significant effect (p = 0.00) of economic level and seasons on the amount and composition of waste generated by the community. Moreover, the collected waste was segregated into 42 categories, where the highest was the organic fraction (57%), then diapers (12%), followed by plastic (8%), cardboard (3%) and paper (2%). The amounts of textile, diapers and plastics were highest in the lowest income group, while tetra packs, metal, paper and yard waste were maximum in the high income group. It is concluded that the high income group generated the highest amount of waste and waste generation rate is higher in the seasons of spring and winter compared to the other two seasons.

“…In EU and the USA it is generally reported that the quantities of HHW arising represent 1% w/w of municipal waste [18][19][20]. Inglezakis and Moustakas [21] collected 36 values of HHW percentage (w/w) in MSW [22][23][24][25][26][27][28][29][30][31][32][33][34][35][36]. The values are presented in Fig.…”
