“…Wastewater is an alternative water source being recently exploited to irrigate biofuel crops without depleting the already scarce water resources. A study by Tsoutsos et al [102] investigated the use of wastewater on the quality of castor bean oil and biodiesel production. Oil samples derived from wastewater irrigation provided a lower concentration of free fatty acids and a slight reduction in viscosity.…”

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.

“…In addition, wastewater can also be a source of other macro-and micronutrients such as Ca, Mg, B, Mg, Fe, Mn or Zn (Henze and Comeau, 2008). Indeed, irrigation with wastewater has been shown to significantly increase the yields of non-edible crops such as lemon grass or rosebushes (Lal et al, 2013;Marinho et al, 2013), and to have a positive impact on oil's quality recovered from sunflower and castor crops (Tsoutous et al, 2013).…”

The reuse of treated wastewater, in particular for irrigation, is an increasingly common practice, encouraged by governments and official entities worldwide. Irrigation with wastewater may have implications at two different levels: alter the physicochemical and microbiological properties of the soil and/or introduce and contribute to the accumulation of chemical and biological contaminants in soil. The first may affect soil productivity and fertility; the second may pose serious risks to the human and environmental health. The sustainable wastewater reuse in agriculture should prevent both types of effects, requiring a holistic and integrated risk assessment. In this article we critically review possible effects of irrigation with treated wastewater, with special emphasis on soil microbiota. The maintenance of a rich and diversified autochthonous soil microbiota and the use of treated wastewater with minimal levels of potential soil contaminants are proposed as sine qua non conditions to achieve a sustainable wastewater reuse for irrigation.

“…In fact, it should be considered that cultivation of non-edible oil crop may be associated with using arable land and consequently increasing load on soil, water and biodiversity (Antizar-Ladislao and Turrion-Gomez, 2008). However, some of the non-edible plants, e.g., castor oil plant, can be cultivated in the wastelands irrigated by wastewater which can suppress the aforementioned challenges (Chakrabarti and Ahmad, 2008;Tsoutsos et al, 2013). Ethanol is industrially produced from sugar and starch based materials; however, it can be produced from inexpensive and abundant lignocellulosic substrates such as agricultural residue, forest residue, and municipal solid wastes Karimi et al, 2013;Misailidis et al, 2009).…”
