“…In previous reports, we observed an increase in translocation for Mn, Fe, As, Zn, Ti, Cr, Cu, Rb, Sr., Al, Ba, K, and Ca when the MAP system based on the arbuscular mycorrhizal (AM) symbiosis established between the sunflower Helianthus annuus and the AM fungal species Rhizophagus intraradices (GA5 strain, https://bgiv.com.ar/strains/ Rhizophagus-intraradices/ga5). The MAP system was applied for the recovery of critical and secondary raw material in sunflower plant biomass, and bioremediation of contaminated mining substrate [34,35].…”

This chapter analyzes the costs-benefits of a particular phytomining methodology named mycorrhizal-assisted phytoremediation (MAP). This MAP system is responsible for phytostabilization and/or phytoextraction of secondary and critical raw materials from contaminated soil or mining wastes. To this aim, we evaluated the application of MAP in a modified constructed wetland, the vegetable depuration module (VDM), which permits the calibration of physical-chemical-biological variables in a contaminated substrate, as well as the partition of chemical elements within the liquid phase due to leaching and solid phases (biomass and soil). This successful methodology allows to scale-up from a Technology Readiness Level (TRL) 6 (demonstration in a relevant environment) toward TRL 7 (demonstration in an operational environment), which implies the transfer to the territory.

“…A successful economy minimizes the production of waste and reuses it as a raw material. Resource constraints and environmental pressures will accelerate the transition from a linear "extraction-use-throw away" model of production and consumption to a circular one: moving towards a near-zero waste society has an environmental rationale and it represents a factor of competitiveness at the same time [1].…”

“…An integrated multidisciplinary approach for characterization and analysis of ironand manganese-rich mine residues in Joda West (State of Odisha, India), and their valorization as a resource, was recently proposed by Guglietta et al [1]. Such an approach would simultaneously promote both economic development and environmental protection.…”

“…The synergy between points 1 and 3 is of particular interest, since it couples low-cost, highly efficient remote sensing and bioremediation technologies. As to remote sensing classification (i.e., point 1), it highlighted mining deposits rich in Fe and Mn in a mine area and all different data were stored in a geodatabase [1], which is a powerful tool for mine waste management and for the selection of samples containing valuable minerals and metals to treat by phytoremediation technique. As to phytoremediation, it is widely recognized as an environmentally friendly technique that uses plants and beneficial microorganisms to remove pollution at greatly reduced costs and minimum adverse side effects [3].…”

“…As to phytoremediation, it is widely recognized as an environmentally friendly technique that uses plants and beneficial microorganisms to remove pollution at greatly reduced costs and minimum adverse side effects [3]. Regarding the bioaccumulation of SRMs by using metal hyperaccumulator plants, it was widely reported that Helianthus annuus (Asteraceae family) can accumulate large amounts of Ni, Mn, Zn, Cu, Pb, As, and Cd [4][5][6] and CRMs such as Ga, Sr, Ti [1,7,8]. This capacity of accumulation in their biomass can be enhanced by association in their roots with the arbuscular mycorrhizal (AM) fungi belonging to the Phylum Glomeromycota [9].…”

In this work, mycorrhizal-assisted phytoextraction (MAP, Helianthus annuus–arbuscular mycorrhizal fungus Rhizophagus intraradices–Zn-volcanic ashes) was applied for the recovery of secondary and critical raw materials (SRMs and CRMs, respectively) from Joda West (Odisha, India) mine residues, within a novel multidisciplinary management strategy. Mine residues were preliminarily characterized by using advanced analytical techniques, and subsequently mapped, classified and selected using multispectral satellite Sentinel-2A images and cluster analysis. Selected mine residues were treated by MAP at laboratory scale, and the fate of several SRMs (e.g., Zn, Cr, As, Ni, Cu, Ca, Al, K, S, Rb, Fe, Mn) and CRMs (such as Ga, Ti, P, Ba and Sr) was investigated. Bioconcentration factors in shoots (BCS) and roots (BCR) and translocation factors (TF) were: 5.34(P) > BCS > 0.00(Al); 15.0(S) > BCR > 0.038(Ba); 9.28(Rb) > TF > 0.02(Ti). Results were used to predict MAP performance at larger scale, simulating a Vegetable Depuration Module (VDM) containing mine residues (1 m3). Estimated bio-extracting potential (BP) was in the range 2417 g/m3 (K) > BP> 0.14 g/m3 (As), suggesting the eventual subsequent recovery of SRMs and CRMs by hydrometallurgical techniques, with final purification by selective electrodeposition, as a viable and cost-effective option. The results are promising for MAP application at larger scale, within a circular economy-based approach.

In recent years, critical and secondary raw materials (CRMs and SRMs, respectively) have received great interest within the circular economy model. In this work, the mycorrhizal-assisted phytomining (MAP) system, composed of Helianthus annuus–arbuscular mycorrhizal fungus Rhizophagus intraradices–Zn-volcanic ashes, was applied in bioreactors for the recovery of CRMs (Sr, P) and SRMs (Cr, Zn, Cu, Mn, Rb, Ni) from mining wastes of the Los Cóndores mine (Argentina). Our results showed high bioaccumulation of Sr, P, Mn, and Zn in the aerial tissues, and a high root-to-shoot translocation for Mn (4.02) > Sr > P > Rb > Zn (0.84). Mycorrhization treatment increased the root-to-leaf translocation for Cr and P and prevented translocation towards flower tissues in most elements. The estimated bioextracting potential of the MAP system (290 plants) in a vegetable depuration module (VDM) ranged from 158 mg/m3 P > Zn > Mn > 15.1 mg/m3 Sr. We demonstrated a promising and cost-effective biotechnology applicable in agronomical practices, given the exclusion of toxic elements in flower parts, as well as for the recovery of CRMs and SRMs by hydrometallurgy from plant biomass.
