“…In contrast, this phenomenon is unfavorable for phytoextraction, which depends on Cu uptake and translocation into the shoot. The lower Cu availability in the soil solution is attributed to the high affinity of Cu for the vermicompost organic compounds and to the formation of lesssoluble complexes in the soil (Jordão et al, 2011;Li et al, 2014). In addition, the increase in soil pH due to vermicompost application resulted in higher Cu complexation by the organic residues added to the soil, thus decreasing Cu bioavailability.…”

“…Vermicompost microbial activities have resulted in reductions in concentrations of various herbicides and heavy metals present in the soils. Vermicompost application decreased the concentration of cadmium ion (1+) (Cd + ) and copper ion (1+) (Cu + ) in tropical soils (Jordão et al., ). Vermicompost contributes in the polarity weakening of polyaromatic hydrocarbons (PAHs) by reducing their thermodynamic tendencies.…”

“…The degradation of the PCP was made possible through the presence of the humic fraction of the vermicomposts and the formation of a PCP-humus complex, which was then decomposed by neutralizing the pH of the soils(Lin et al, 2016).Vermicompost microbial activities have resulted in reductions in concentrations of various herbicides and heavy metals present in the soils.

Improperly managed organic waste constitutes a serious environment threat across the globe. This has led to a worldwide struggle to strike a balance between the rapid generation of such wastes and protection of the environment. With the unique advantages of lower operational and maintenance costs compared with other waste management technologies, the use of vermicomposting to manage organic wastes has been increasing rapidly in recent years. Still, some factors (e.g., characteristics of substrate composition before and after treatment) are in need of additional, specific studies so that researchers can better understand the metabolism involved in the process. Vermicomposting provides employment opportunities as it protects the environment, augmenting crop productivity when it is used as a fertilizer supplement and helping to maintain ecological balance. Thus, vermicompost plays an important role in the circular economy. This article provides an overview of the research activities that have been conducted on the use of vermicomposts to remove pollutants from the soil, in wastewater treatment, and in organic waste recycling throughout the world. Circular economic assessment has revealed that vermicomposting technology is usually feasible except in certain cases. Most other methods of waste disposal lead to soil deterioration, toxic effects, and increased pollution affecting land, air, water, and living beings, in addition to the sometimes considerable expense of their implementation. Thus, an eco‐friendly method that removes waste in one step is needed. Determining the long‐term performance and sustainable operation of vermicomposting systems still poses a challenge, however, as treatment performance is affected by design parameters, operational conditions, and environmental factors. This article summarizes the factors influencing pollutant removal through the vermicomposting process. Finally, this article highlights additional research that should be conducted on these issues to improve the performance of vermicomposting.

“…In order to minimize the pollution of soils by heavy metals, Jordão et al [ 57 ] added vermicompost to tropical soils with the intention of decreasing the mobility of Cd 2+ and Cu 2+ . The authors achieved satisfactory results, which can be explained by accentuated spontaneity related to adsorptive processes (ΔG around −14,000 kJ mol −1 ).…”

“…The authors achieved satisfactory results, which can be explained by accentuated spontaneity related to adsorptive processes (ΔG around −14,000 kJ mol −1 ). The work of Jordão et al [ 57 ] shows that vermicompost is able to bioremediate soils containing metallic species and this ability is also extended to other organic substrates [ 58 ]. According to Park et al [ 59 ], bioremediation of metals by organic substrates is a consequence of the following mechanisms: (1) immobilization, (2) reduction, (3) volatilization, and/or (4) modification of the rhizosphere.…”

The use of vermicompost (humified material) for treating wastewaters, remediating polluted soils, improving agricultural productivity, protecting crop production, and developing sensitive analytical methods is reviewed here, covering the past 17 years. The main advantages of vermicompost, considering all applications covered in this paper, comprise (i) easy acquisition, (ii) low costs, (iii) structural, chemical, and biological characteristics responsible for exceptional adsorptive capacities as well as pollutant degradation, and (iv) the promotion of biocontrol. Specifically, for wastewater decontamination, a considerable number of works have verified the adsorption of toxic metals, but the application of vermicompost is still scarce for the retention of organic compounds. Problems related to the final disposal of enriched vermicompost (after treatment steps) are often found, in spite of some successful destinations such as organic fertilizer. For decontaminating soils, the use of vermicompost is quite scarce, mainly for inorganic pollutants. In agricultural productivity and biocontrol, vermicompost imparts remarkable benefits regarding soil aggregation, plant nutrition, and the development of beneficial microorganisms against phytopathogens. Finally, the use of vermicompost in sensitive analytical methods for quantifying toxic metals is the newest application of this adsorbent.
