“…For comparison, the EC of oceans is 56 mS cm -1 , and that of the rainwater used to irrigate the column leaching experiment was 290.4 μS cm -1 . The pH values found in this study approximated the values measured by Bilibio et al (2021b) for the drainage water of different technogenic substrates after three experimental years in a lysimeter experiment (7.2). However, the low pH measured in the same study (Bilibio et al, 2021b) in the first experimental year after saturation (average 5.3) was not confirmed in the current column leaching experiment.…”

“…Frontiers in Environmental Science frontiersin.org static covers, such as residue of aluminium recycling (Niessing, 2005). Currently, the focus has been on revegetation through an evapotranspiration cover made of municipal solid waste incineration bottom ash and coal combustion residues (CCRs), due to their high availability and affordability (Bilibio et al, 2017a;2021a;2021b;Bilibio and Hensel, 2021). Germany produces 49.570 million tons of municipal solid waste annually (Nelles et al, 2016), which must be recycled, composted, or incinerated.…”

Technosols are characterized by a substantial quantity of artifacts or industrial wastes in the upper 100 cm. They can be used as cover caps in mining rehabilitation, in which vegetation cover is subsequently established. However, prolific vegetation growth can be limited by the chemical and physical properties of technogenic substrates. As further studies need to be conducted to evaluate the suitability of municipal solid waste incineration bottom ash and coal combustion residues as cover caps, the pH, electrical conductivity, total porosity, and bulk density of these substrates were measured. Furthermore, the seepage pH and electrical conductivity of the covered and uncovered technosols after saturation were determined. The municipal solid waste incineration bottom ash, 4–10 mm in diameter, showed the highest bulk density (1.16 g cm-3) and lowest total porosity by saturation (24.7%). In contrast, the coal combustion residues registered the highest total porosity (57.2%). The coal combustion residues also revealed a higher pH of 12.5 and electrical conductivity values of 7.8 mS cm-1. Furthermore, no differences were observed between the treatments for pH seepage (8.2–8.3) and its electrical conductivity (14.3–16.0 mS cm-1) in the covered and uncovered columns, when using a technosol. This study provides information on the use of municipal solid waste incineration bottom ash and coal combustion residues as evapotranspiration covers during mining rehabilitation. The management of municipal solid waste residues is a global challenge and the use of this resource is valuable not only for the mining industry but potentially also in other fields, such as construction. The heavy metal content of the bottom ash from municipal solid waste incineration and coal combustion residues should be studied before implementing these waste residues on a large scale.

“…The condition of substrate moisture over time is also thought to be influenced by the type of vegetation habitus in each area, while the pH of the substrate decreases over time (Figure 6). This is thought to be related to the presence of heavy metals in the overburden (Table 5), which are oxidized with air and water, resulting in acid mine drainage (AMD) (Bilibio et al, 2021). The decrease in substrate pH is also driven by the physicochemical properties of Warukin Formation overburden, which tends to be sandy, high in sulfide elements, and has the potential to turn the material into acid or PAF (potential acidforming) (Pratama, 2015;Agustin et al, 2020).…”

Overburden (the dumping of mine tailings and other reject materials) from the Warukin geological formation is one of the potential acid-forming (PAF) of 33.17%. Mining can cause overburden to be exposed and affect biotic and abiotic conditions. The study aimed to analyze the biotic and abiotic factors of three different age overburdens from the Warukin Formation, South Kalimantan. Biotic factor measurements included vegetation sampling using line transect, soil insects using pitfall traps, and microbial using total plate count. Abiotic factor measurements included air temperature and humidity, light intensity, temperature, moisture, and pH of the substrate (n=3), and chemical overburden. Identification of plants and insect species using information from locals, identification books, and websites. Plant species diversity was analyzed using the Shannon-Wiener Index. Dominance species were analyzed using the Important Value Index (IVI). The relation of overburden age on biotic and abiotic factors was analyzed multivariate with Non-Metric Multidimensional Scaling (NMDS). The results showed that there are 102 species of plants and 11 species of soil insects. The numbers of fungi and bacteria are 10-4 CFU g-1 and 10-3 CFU g-1, respectively. Plant species diversity is classified as medium (H'= 2.34; 2.50 and 2.82). Changes in plant composition occurred as the microclimate and substrate nutrition improved. The organic matter increased over time. Humidity and light intensity influence the presence and composition of organisms, while pH values affect the adaptability of plants, insects, and microbes. Heavy metal concentrations have increased due to the physicochemical properties of the Warukin formation overburden.
