Crude oil and bioproducts of castor bean (Ricinus communis L.) plants established naturally on metal mine tailings

Abstract: Previous research suggested that Ricinus communis may be used for soil remediation and oil production. However, the quality of the oil and bioproducts under polluted conditions need to be tested to be assured of their potential use in biofuel production with environmentally friendly bioproducts (cake, seed coats and biomass). Oil characteristics and metal concentrations in oil, cake (deoiled seeds) and seed coats, as well as the shoot carbon content were analyzed. The oil contents of palmitic and oleic acids f… Show more

“…Castor bean cake has also shown great potential for biogas production and was found to be a very interesting feedstock for the production of pyrolysis bio-oil [124,125]. According to Gonzalez-Chavez et al [46], castor bean cake derived from plants naturally established on polluted mine-tailings can be utilized as organic fertilizer due to the lower levels (e.g., Pb in cake: 2.6-8.8 mg•kg −1 ) of metal contamination allowed by EU regulations (e.g., maximum limit values of Pb in organic fertilizer: 120 mg•kg −1 of dry matter) [126].…”

“…India produces about 90% of the castor oil in the world (33). R. communis bioproducts like seed cake and seed coats are used as fertilizer to improve soil quality (34). The detoxified or refined seed protein would be used as fish feed, farm animals, poultry, pig rearing and seed cake is used as good fertilizer (35).…”

“…Ricinus communis L. is observed grown naturally on mine tailings and also found a potential source for phytoremediation and produces good quantity of oil [7]. Similarly, good content of linoleic acid in oil produced from R. communis grown on mine tailings which enriches its fuel properties [82]. Phytoextracting plants such as Sesamum indicum and Cyamopsis tetragonoloba are used for bioremediation of Cu-contaminated soil [83].…”
