“…Indexes such as accumulation capacity (Schickler and Caspi 1999), the bioaccumulation factor (BCF) (Luo et al 2020), the translocation factor (TF) (Goswami and Das 2015), and tolerance capacity (Yang et al 2004), are used to assess whether a speci c plant has robust phytoextraction ability. Several studies have revealed the mechanism of interactions between plants and pollutants and provided important information for selecting plant species with signi cant metal accumulation potential (Lasat 2002;Liu et al 2016).…”

Traditional phytoremediation is one means for remediation of heavy metal pollution. For developing countries, the key factor in promoting the practical application of phytoremediation in polluted soils is selecting suitable plants tolerant to heavy metals and using these to produce products with economic value. A chicory-tobacco-peanut, three-season, rotation field experiment was carried on the utilization and remediation of cadmium (Cd) in contaminated farmlands. The results showed that all three crops had a strong capacity to accumulate Cd, with bioconcentration factors of chicory, tobacco, and peanut 6.61 to 11.97, 3.85 to 21.61, and 1.36 to 7, respectively. The yield of total dry biomass and phytoextraction efficiency for Cd reached 32.4 t ha-1 and 10.3% per year, respectively. The aboveground tissues of the three crops accounted for 83.9–91.2% of the total biomass in this rotation experiment. The content of peanut grain and oil met the National Food Safety Standard of China (0.5 mg kg-1, GB 2762-2017) and the Food Contaminant Limit of the European Union (0.1 mg kg-1, 18812006). Therefore, in addition to being used for phytoremediation in contaminated soils, this crop rotation system can also lead to economic benefits for local farmers.

“…In addition, arid or semi-arid areas with reduced vegetation condition greater pollution due to the dispersion of particles with the wind, since there is no vegetation that retains these residues [7]. However, it is not common for vegetation to develop in the deposits of tailing from washing plants, as the presence of heavy metals has a significant influence on the flora [8][9][10]. They are therefore large deposits of mining waste that change over time by various processes of erosion with associated pollution, destroying the landscape of the area [11][12][13].…”

Mining activity is essential for the social welfare of the population. However, this activity produces a series of mining waste. These mining wastes, if not properly treated, can produce significant environmental pollution. This study develops the incorporation of tailings from washing plants in ceramic materials for bricks in order to retain the contaminating elements in the ceramic matrix. To this end, firstly, a physical and chemical characterisation of the mining waste is carried out and different groups of samples are conformed with clay and mining waste. These conformed samples with mining waste are evaluated through different physical and mechanical tests typical in the ceramic industry, studying the variation of properties by the incorporation of the waste. In turn, the leachates from the groups of conformed samples are analyzed, confirming the retention of the contaminating elements of the mining waste in the ceramic matrix. The results of these tests showed that ceramics can be made for bricks with up to 90% mining waste, obtaining physical and mechanical properties acceptable regarding the regulations and retaining the contaminating elements in the ceramic matrix, as confirmed by the leachate tests.

“…The hypertolerance toward toxic metals can be explained by (I) detoxification by complexation, (II) metal sequestration in cellular compartments, and (III) metal sequestration via exocellular deposition [19]. The capability of hyperaccumulation for Ni 2+ , Co 2+ , and Mn 2+ ions was described for different species, and the application of plants for the detoxification of soils has been demonstrated (phytoremediation) [19][20][21][22][23][24]. This low-cost and green technology constitutes a valuable niche compared to expensive conventional soil remediation approaches.…”

Phytoremediation of Soil Contaminated with Lithium Ion Battery Active Materials—A Proof-of-Concept Study

The lithium-ion battery is the most powerful energy storage technology for portable and mobile devices. The enormous demand for lithium-ion batteries is accompanied by an incomplete recycling loop for used lithium-ion batteries and excessive mining of Li and transition metals. The hyperaccumulation of plants represents a low-cost and green technology to reduce environmental pollution of landfills and disused mining regions with low environmental regulations. To examine the capabilities of these approaches, the hyperaccumulation selectivity of Alyssum murale for metals in electrode materials (Ni, Co, Mn, and Li) was evaluated. Plants were cultivated in a conservatory for 46 days whilst soils were contaminated stepwise with dissolved transition metal species via the irrigation water. Up to 3 wt% of the metals was quantified in the dry matter of different plant tissues (leaf, stem, root) by means of inductively coupled plasma-optical emission spectroscopy after 46 days of exposition time. The lateral distribution was monitored by means of micro X-ray fluorescence spectroscopy and laser ablation-inductively coupled plasma-mass spectrometry, revealing different storage behaviors for low and high metal contamination, as well as varying sequestration mechanisms for the four investigated metals. The proof-of-concept regarding the phytoextraction of metals from LiNi0.33Co0.33Mn0.33O2 cathode particles in the soil was demonstrated.
