“…For example, a high-Zn biomass content could be searched in the case of the emerging eco-catalysis valorization chain [20]. The produced biomass on a TE-contaminated site could be used in the energy sector [17,19,[21][22][23] and as a feedstock to create high-value products [24][25][26][27]. Among the value chains currently studied on contaminated sites in northern Europe, the energy sector seems prominent, as shown by the numerous field experiments set up with, notably, Miscanthus giganteus, Salix sp., Populus sp., or Zea mays [3,4,19,24,28].…”

Phytoattenuation combines phytoextraction or phytostabilization with the economic valorization of the biomass produced on the contaminated soil. Sorghum bicolor is a suitable crop for this strategy, as it is known to be metal-tolerant and can be used for biogas or bioethanol production or in strategies toward biofortification. In the current investigation, two cultivars, Biomass 133 and Trudan Headless (HL), were studied in a metal-contaminated (Cd, Pb, Zn) field site located in northern France to assess their potential use in a phytoattenuation strategy. The biomass yield and the metal transfer in the produced biomass were monitored in three plots with different pollution levels. Both cultivars were tolerant to high levels of metal pollution in field conditions, with yields similar to that obtained on uncontaminated sites. Neither of the cultivars changed the metal mobility of the soil and both exhibited a metal-excluder behavior. Nevertheless, Cd concentration in the aboveground part of Trudan HL, and of Biomass 133 to a lesser extent, could restrict their use in some valorization options. However, biogas production was possible with the produced biomass, indicating anaerobic digestion to be a possible valorization route for sorghum grown on contaminated sites.

“…For comparison purposes, soil pH was neutral at the Bettwiesen site (7.1) but 0.1M NaNO 3 -extractable concentrations (in mg kg −1 ) were 0.15–55 for Zn and 0.003–0.01 for Cd (Herzig et al 2014 ), therefore of the same magnitude order as compared to the Borifer soil (Table 1 ). Indeed, such bioavailable Zn and Cd stripping and its potential influence on pollutant linkages (e.g., herbivory, Grignet et al 2020 ) must be in situ investigated at the Borifer site to get a better assessment. In such sandy soil, it is also possible to harvest the root systems of tobacco, which generally display high Pb and Cu concentrations (Kolbas et al 2020 ).…”

“…The resupply of the phytoavailable soil fraction will be regulated by the metal(loid)-bearing solid phases and the soil properties, including the soil pH and Eh. Other Zn/Cd-phytoextraction options are reported in Europe: e.g., Salix viminalis L. and Arabidopsis halleri (L.) O’Kane & Al-Shehbaz alone and in inter-row co-cropping at the urban Montataire site, Oise County, France (Grignet et al 2020 ), Noccaea caerulescens (J. Presl & C. Presl) F. K. Mey (Jacobs et al, 2019 ), short rotation coppice of poplars and willow, and sunflower (Thijs et al 2018 ) . However, the growth of these plant species would be likely limited by the hot and dry summer weather conditions in southwest France.…”

“…In addition, foliar Zn and Cd concentrations can decrease with growth and successive cuts. Therefore, the selection of the harvested shoot parts and their age are an important factor (Grignet et al, 2020;Grzegórska et al, 2020). Trees growing at brownfield and landfill sites can exhibit higher lignin content than those cultivated in uncontaminated soils due to abiotic stresses, e.g., drought-stress, leading to lower glucose yield (Edgar et al, 2021).…”

“…On the other hand, TE accumulation in willow can differ between the plant parts (roots, twigs, leaves, etc.). The ability of willow trees to recover contaminated sites has successfully been tested in field trials (e.g., Van Ginneken et al, 2007;Vangronsveld et al, 2009;Mench et al, 2010;Kacálková et al, 2015;Kidd et al, 2015;Enell et al, 2016;Courchesne et al, 2017;Thijs et al, 2018;Xue et al, 2018;Grignet et al, 2020) and some examples are given in Table 2.…”

The growing loss of soil functionality due to contamination by metal(loid)s, alone or in combination with organic pollutants, is a global environmental issue that entails major risks to ecosystems and human health. Consequently, the management and restructuring of large metal(loid)-polluted areas through sustainable nature-based solutions is currently a priority in research programs and legislation worldwide. Over the last few years, phytomanagement has emerged as a promising phytotechnology, focused on the use of plants and associated microorganisms, together with ad hoc site management practices, for an economically viable and ecologically sustainable recovery of contaminated sites. It promotes simultaneously the recovery of soil ecological functions and the decrease of pollutant linkages, while providing economic revenues, e.g. by producing non-food crops for biomass-processing technologies (biofuel and bioenergy sector, ecomaterials, biosourced-chemistry, etc.), thus contributing to the international demand for sustainable and renewable sources of energy and raw materials for the bioeconomy. Potential environmental benefits also include the provision of valuable ecosystem services such as water drainage management, soil erosion deterrence, C sequestration, regulation of nutrient cycles, xenobiotic biodegradation, and metal(loid) stabilization. Phytomanagement relies on the proper selection of (i) plants and (ii) microbial inoculants with the capacity to behave as powerful plant allies, e.g., PGPB: plant growth-promoting bacteria and AMF: arbuscular mycorrhizal fungi. This review gives an up-to-date overview of the main annual, perennial, and woody crops, as well as the most adequate cropping systems, presently used to phytomanage metal(loid)-contaminated soils, and the relevant products and ecosystems services provided by the various phytomanagement options. Suitable bioaugmentation practices with PGPB and AMF are also discussed. Furthermore, we identify the potential interest of phytomanagement for stakeholders and end-users and highlight future opportunities boosted by an effective engagement between environmental protection and economic development. We conclude by presenting the legal and regulatory framework of soil remediation and by discussing prospects for phytotechnologies applications in the future.
