“…The last few years, phytotechnologies have progressively shifted to phytomanagement, a concept which included the valorization of the plant biomass produced on contaminated sites, to generate economic revenue (Evangelou and Deram, 2014). Although some valorization options have been deeply investigated and provided opportunities for such biomass Chalot et al, 2012;Delplanque et al, 2013) phytomanagement is still scarcely applied in European countries and suffer from lack of field experiment feedbacks (Cundy et al, 2013).…”

This study aimed at evaluating the mid-term effect of ecto-and endomycorrhizal inoculation on the reduction of PTE mobility in soils and foliar accumulation by two poplar clones, Skado (Populus trichocarpa x P. maximowiczii) and I-214 (P. deltoides x P. nigra), dedicated to bioenergy purposes. The effects of inoculation were investigated in two large scale trials of 1 ha each. Poplars grown on highly contaminated soils accumulated excessive Cd and Zn in leaves compared with those planted on less contaminated soils, and the I-214 clone generally accumulated less PTEs than the Skado clone. Interestingly, the filtering capacity of mycorrhizal fungi was significant for Zn, Cu, Pb and Cr in Skado leaves only at the most contaminated areas after two growing seasons. These foliar concentrations were not correlated with Ca(NO3)2-extractable concentrations in soils, suggesting that mycorrhizal fungi limited PTE translocation from roots to leaves without impacting PTE mobility in soils. Therefore, the reduction of PTE accumulation in poplar leaves may be optimized by selecting appropriate combinations of cultivars and inocula at specific PTE levels and soil conditions.Because Cd and Zn may pose a risk after leaf abscission and wood harvest, further research is needed to efficiently reduce Cd and Zn concentrations in poplar tissues. Otherwise, the phytomanagement of metal contaminated sites with poplars should include options to safely manage both leaves and wood.

“…Combustion of metal-enriched woody biomass resulting from phytotechnologies was recently explored at pilot scale regarding the fate of metals in emissions and associated regulatory aspects. 4,5 Highest concentrations of Cd and Zn were found in fly ash compared to bottom ash. From these studies, the combustion of metal enriched poplars and willows in boilers equipped with efficient filters is recommended to minimize air pollution and comply with regulatory thresholds.…”

A questionnaire survey was carried out in four European countries to gather end-user's perceptions of using plants from phytotechnologies in combustion and anaerobic digestion (AD). Nine actors of the wood energy sector from France, Germany, and Sweden, and eleven AD platform operators from France, Germany, and Austria were interviewed. Questions related to installation, input materials, performed analyses, phytostabilization, and phytoextraction were asked. Although the majority of respondents did not know phytotechnologies, results suggested that plant biomass from phytomanaged areas could be used in AD and combustion, under certain conditions. As a potential benefit, phytomanaged plants would not compete with plants grown on agricultural lands, contaminated lands being not suitable for agriculture production. Main limitations would be related to additional controls in process' inputs and end-products and installations that might generate additional costs. In most cases, the price of phytotechnologies biomass was mentioned as a driver to potentially use plants from metal-contaminated soils. Plants used in phytostabilization or phytoexclusion were thought to be less risky and, consequently, benefited from a better theoretical acceptance than those issued from phytoextraction. Results were discussed according to national regulations. One issue was related to the regulatory gap concerning the status of the plant biomass produced on contaminated land.

“…(Imada et al 2009;Sebastiani et al 2004;Wu et al 2010), Salix spp. (Lewandowski et al 2006), Liquidambar styraciflua, Platanus occidentalis, Robinia pseudoacacia, Acer saccharinum L. and Eucalyptus can be grown for other uses also such as paper production and the waste can be utilized for energy (Capuana 2011;Claudia et al 2012;Delplanque et al 2013). Hibiscus cannabinus (Kenaf), Brassica juncea (Indian mustard), Helianthus annus (Sunflower), Ricinus communis (Castor), Vetiveria zizanioides (Khus Khus grass) Prosopis juliflora (Velvet Mesquite), are potential candidates for phytoremediation and carbon sequestration.…”

Environmental decontamination is an integral part of sustainable development. In recent years there has been growing interest in using plants for decontamination. On the other hand, water, soil and air are increasingly contaminated. Large amounts of toxic waste have been dispersed in thousands of contaminated sites spread all over the globe. These pollutants belong to two main classes: inorganic and organic. The challenge is to develop innovative and costeffective solutions to decontaminate polluted environment. Phytoremediation is emerging as an invaluable tool for environmental cleanup. Various strategies are being applied to reduce the accumulation of toxic metals in plants. Cultivation of edible crops in contaminated soils is a subject of human health concern if the contaminant concentration in the edible parts of crops plant exceed the permissible level. In such cases non-food crop production viz. value chain and value additions appears profitable. In this review: (1) the contamination due to industrial effluents in peri urban region of greater Hyderabad, and (2) the strategies to use contaminated soil and water for raising phytoremediation crops, and generation of value products. Crops and products include medicinal and aromatic plants, ornamental plants, biofuels, tree crops, fiber crops, dyes, and plants for carbon sequestration.
