“…Synthetic chelates, such as ethylenediaminetetraacetic acid (EDTA) or ethylenediamine disuccinic acid (EDDS), can increase the plant's ability to uptake cadmium [181]. EDDS was shown to be the most suitable chelate for phytoremediation of Cd in soil [182]. In addition to chelates, the application of water-soluble chitosan also enhances Cd uptake [36].…”

Biofuel Production with Castor Bean: A Win–Win Strategy for Marginal Land

The urgency to reduce resource depletion and waste production is expected to lead to an economy based on renewable resources. Biofuels, for instance, are a great green alternative to fossil fuel, but they are currently derived from edible vegetable oils such as soybean, palm, and sunflower. Concerns have been raised about the social–economic implication and ecological impacts of biodiesel production. Cultivating new lands as biodiesel feedstock rather than food supply, with the consequent increase in food prices, leads to so-called indirect land-use change (ILUC). Establishing bioenergy crops with phytoremediation ability on contaminated soils offers multiple benefits such as improving soil properties and ecosystem services, decreasing soil erosion, and diminishing the dispersion of potentially toxic elements (PTEs) into the environment. Castor bean is an unpalatable, high-biomass plant, and it has been widely demonstrated to possess phytoremediation capability for several PTEs. Castor bean can grow on marginal lands not suitable for food crops, has multiple uses as a raw material, and is already used in biodiesel production. These characteristics make it perfect for sustainable biodiesel production. Linking biofuel production with environmental remediation can be considered a win–win strategy.

“…Chelator is one type of bonding ion, which involves in the formation of two or more separate coordinate bonds. Citric acid (CA), ethylenediamine disuccinic acid (EDDS) chelates effect the growth, heavy metal accumulation, metal bioavailability in the rhizhosphere and the non-rhizosphere on metal accumulation and enhance the phytoremediation efficacy in castor bean of Cd and Pb contaminated soils (54). Ethylene diamine tetra acetic acid (EDTA), nitriloacetic acid (NTA), ammonium citrate have accelerated Cd uptake in R. communis in Cd contaminated soils (55).…”

Phytoremediation is a plant based environmental cleanup technology to contain (rendering less toxic), sequester and degrade contaminated susbtrates. As can be seen from data metrics, it is gaining cosiderable importance globally. Phytoremediation approach is being applied for cleanup of inorganic (potentially toxic metals), organic (persistent, emergent, poly-acromatic hydrocarbons and crude oil etc.) and co-contaminated (mixture of inorganic and organic) and/or polluted sites globally. Recently new approaches of utilizing abundantly available natural organic amendments have yielded significant results. Ricinus communis L. (Castor bean) is an important multipurpose crop viz., Agricultural, Energy, Environmental and Industrial crop. The current status of knowledge is abundant but scattered which need to be exploited for sustainable development. This review collates and evaluates all the scattered information and provides a critical view on the possible options for exploiting its potential as follows: 1. Origin and distribution, 2. Lead toxicity bioassays, 3. Progress in arbuscular mycorrhizal fungi-assisted phytoremediation, 4. Promising bioenergy crop that can be linked to pytoremediation, 5. A renewable source for many bioproducts with rich chemical diversity, 6. It is a good biomonitor and bioindicator of atmospheric pollution in urban areas, 7. Enhanced chelate aided remediation, 8. Its rhizospheric processes accelerate natural attenuation, 9. It is suitable for remediation of crude oil contaminated soil, 10. It is an ideal candidate for aided phytostabilization, 11. Castor bean is a wizard for phytoremediation and 12. Its use in combined phytoextraction and ecocatalysis. Further, the knowledge gaps and scope for future research on sustainable co-generation of value chain and value addition biobased products for sustainable circular economy and environmental security are described in this paper.

“…Jatropha curcas (jatropha), for example, is a potential plant for phytoremediation of land or soil polluted with various heavy metals (Edao 2017). Ricinus communis (castor bean) has also been known to have the ability to stabilize residues and lower metal levels (Olivares et al 2013), as well as to grow well in the presence of lead (Zhang et al 2015). Reutealis trisperma (candlenut), a tree species, has good adaptability to grow in marginal lands such as posttin mining soil, very dry land, and acidic soils (Pranowo et al 2015), and was able to adapt to the gold mine's liquid waste (Hamim et al 2017).…”

Abstract. Andriya NN, Hamim H, Sulistijorini, Triadiati. 2019. The phytoremediation potential of non-edible oil-producing plants for gold mine tailings. Biodiversitas 20: 2949-2957. Plants can be used as phytoremediation agents to reduce environmental pollutants including heavy metal contaminants produced due to industrial activities. The objective of this study was to analyze the morphological, anatomical, and physiological responses of four non-edible oil-producing plants namely Jatropha curcas, Ricinus communis, Reutealis trisperma, and Melia azedarach and their ability to absorb and accumulate lead (Pb) when grown in different concentrations of gold mine tailings. The study was conducted using a completely randomized design involving two factors, four different species of plants and three different concentrations of tailings (0%, 50%, and 100%). Gold mine tailings caused a decrease in the growth of all species indicated by a significant reduction in plant height, leaf number, leaf area, shoot as well as root dry weight, while it significantly increased green RGB values of leaves. Pb accumulation was detected in the root as well as leaf tissues of the plant-based on histochemical analysis. The treatment with tailings also caused an increase in lipid peroxidation levels as indicated by increased malondialdehyde content in the roots and leaves. On the other hand, chlorophyll and carotenoid content decreased due to tailings treatment, along with the relative water content. Among the four species investigated, R. trisperma was found to be the most resistant species to gold mine tailings based on its ability to maintain growth even during gold tailing stress, which is also supported by principal component analysis.
