“…One of them is landfill mining, which includes the recovery of buried resources from a landfill with upgrading of the existing landfill to mitigate the environmental problems (Hogland et al, 2004; Kurian et al, 2003). Prior research has demonstrated that landfilled waste can be categorized as coarse and fine fractions (Hogland et al, 2004; Kurian et al, 2003; Quaghebeur et al, 2013; Rong et al, 2017). The coarse fraction consists of material that can be categorized into different streams such as paper/cardboard, plastic, textile, wood and others, whereas the fine fraction generally represents a mix of degraded materials, inorganics and cover soil.…”

“…However, for the viability of a landfill mining project, a possible application of the fine fraction also needs to be identified. The fine fraction is also referred to as soil fraction, soil-like fraction and soil type fraction in the literature (Rong et al, 2017; Zhou et al, 2015). This fraction exhibits heterogeneity from place to place and is, moreover, contaminated by components like microplastic, glass, organics and heavy metals (Bhatnagar et al, 2017; Kaartinen et al, 2013).…”

Improper municipal solid waste management in the past has landed most of this waste in open dumps of India. This dumped waste has a negative effect on the environment and human health and needs to be reclaimed either for material/energy recovery or to create space for future waste management. Since nearly half of the waste in dumpsites can be classified as fine fraction, in-depth knowledge of its characteristics is required to reclaim these dumpsites successfully. In this study, we characterize fine fraction, <4 mm, aged 1–10 years old, obtained from Mulund dumpsite in Mumbai, using physicochemical and spectroscopic analysis. The study also highlights different valorization routes to reclaim the fine fraction. The fine fraction was ~45% in the dumpsite and increased with the age of the waste. Visual inspection revealed that fine fraction older than five years was relatively homogeneous compared with younger fine fraction. Furthermore, pH (7.4–7.8) and electrical conductivity (0.70–1.92 mS cm−1) of the fine fraction met the Indian MSW compost standards; however, heavy metal levels were higher than the proposed standards. The fine fraction also had a high concentration of metals like aluminium (11 g kg−1) and iron (78 g kg−1), indicating metal recovery potential. Furthermore, Fourier Transform Infrared Spectroscopy results show that the fine fraction had dominant inorganic peaks and became relatively homogeneous with age. The study proposes fine fraction use as a secondary resource; however, some prior treatment would be required based on the application.

Utilisation of industrial solid wastes to prepare products with high added value is an effective way that could relieve environmental pollution and create huge economic benefits. In this work, steel slag based permeable brick (SSPB) was successfully prepared by liquid phase sintering. The BSE-EDS results indicate that the microstructure of the SSPB becomes dense because of the formation of a small amount of glass-liquid phase (Na-K-Ca-Fe-Si-O glass system). The effect of sintering temperature on various properties of the SSPB was systematically studied. It is found that as the sintering temperature increases from 1210 to 1300°C, the permeability deceases gradually, as well as the apparent porosity, water retention and water absorption.In contrast, the bulk density and mechanical strengths show gradually increasing trends. Most important of all, the SSPB sintered at 1270°C for 1 hour shows an excellent permeability (5.70 × 10 −2 cm/s) and high mechanical strengths (compressive strength, 36.6 MPa; bending strength, 6.8 MPa). The prepared SSPB is not only likely to be a new type of permeable brick for sidewalk construction, but also relieve greatly environmental pollution from steel slag because of the high utilisation rate of steel slag (as high as 90%).

“…Oliveira et al (2015) observed that the applications of organic material, by means of swine manure, did not influence the soil structure and Barbosa et al (2015) observed in experiment of eight years duration in a Red Latosol (Oxisol), that the aviary manure improves the soil structure in the first 15 days after the application. As for the LL, the information is commonly directed to the works that evaluate the phyto-extraction of heavy metals through the development of plants and processes of sorption and desorption in clays, in areas of landfill, already infected, as in Coelho et al (2016), Salam et al (2016) and Rong et al (2017).…”

The organic carbon present in the landfill leachate (LL) can improve the physical quality of the soil when applied in agricultural areas, minimizing the problem of disposal of this waste. The objective of this work was to evaluate the effect of the application of different doses of LL on the physical quality of the LATOSSOLO VERMELHO (Oxisol) after five years of applications. The treatment consisted of applications of LL in doses of 32, 65, 98 and 130 m 3 ha -1 crop -1 and the treatment that receives mineral fertilizer. The physical quality of the soil was evaluated in soil samples collected in the layers 0.00-0.10 and 0.10-0.20 m, through the analysis of stability and diameter of the aggregates, soil density, total aeration capacity, field capacity and available water content. After five years of application of LL, at doses of 65, 98 and 130 m 3 ha -1 crop -1 have promoted a linear increase of the aggregates with diameter greater than 2.00 mm, of the weighted average and geometric diameters and of the soil density, with a consequent reduction of the ratio between macro and micropores and the aeration capacity of the layers 0.00-0.10 and 0.10-0.20 m. After five years of these applications, the soils that received the dose of 32 m 3 ha -1 crop -1 presented the best physical quality in relation to the other doses, since this dose did not promote an increase of the aggregates larger than 2 mm in the superficial layer (0.00-0.10 m) and was the dose with lower effect in the reduction of aeration of the soil, in relation to the others (65, 98 and 130 m 3 ha -1 crop -1 ) in the layers 0.00-0.10 and 0.10 -0.20 m.

Após cinco anos de aplicações de LAS, nas doses de 65, 98 e 130 m 3 ha -1 safra -1 promoveram aumento linear dos agregados com diâmetro maior que 2,00 mm, dos diâmetros médio ponderado e geométrico e da densidade do solo, com consequente redução da razão entre macro e microporos e da capacidade de aeração das camadas 0,00-0,10 e 0,10-0,20 m. Após cinco anos de aplicações de LAS, os solos que receberam a dose de 32 m 3 ha -1 safra -1 apresentaram a melhor qualidade física em relação às demais doses, pois, essa dose não promoveu aumento dos agregados maiores que 2 mm na cama...
