Non-Edible Plant Oils as New Sources for Biodiesel Production

Abstract The yellow fever mosquito, Aedes aegypti (Diptera: Culicidae) transmits several devastating arboviruses, including dengue, chikungunya, and Zika virus, making development of inexpensive and eco-friendly strategies for its control an urgent priority. We evaluated the lethality of 13 commonly used plant-derived edible oils against late-third instar Ae. aegypti and then tested the three most lethal oils for stage-specific differences in lethality. We also examined the effects of the most lethal (hempseed), moderately lethal (sunflower and peanut), and least lethal (olive) oils on survival to adulthood and oviposition behavior of gravid females. We hypothesized that the insecticidal activity of edible oils is a function of the content of their linoleic acid, a key fatty acid component with film-forming properties. Among the 13 oils tested, hempseed oil was the most lethal, with an LC50 of 348.25 ppm, followed by sesame (670.44 ppm) and pumpkinseed (826.91 ppm) oils. Oils with higher linoleic acid content were more lethal to larvae than those with low linoleic acid content. Furthermore, pure concentrated linoleic acid was more lethal to larvae compared to any edible oil. In comparison to early instars, late instars were more susceptible to hempseed, sunflower, peanut, and olive oils; these oils also acted as oviposition deterrents, with effective repellency ≥63%. The proportion of larvae surviving to adulthood was significantly reduced in hempseed, sunflower, peanut, and olive oil treatments relative to controls. Our results suggest that some edible plant oils have potential as effective, eco-friendly larvicides, and oviposition deterrents for controlling container-dwelling mosquitoes, especially in resource-limited settings.

The problem of fossil fuel increases by time around the world, Biodiesel is an environmentally friend renewable diesel fuel alternative. The present work aims to determine the possibility for biofuel production from non-edible plant (Water hyacinth) and waste cooking oils in addition to potential uses as source for glycerol, pigments and antioxidant compound sources. this study aimed to investigate the feasibility of biodiesel production from water hyacinth using two solvent systems (chloroform: methanol, 2:1v/v and Hexane), Moreover, WCO applying one steps alkaline transesterification process using methanol, NaOH (0.25) and KOH (0.25, 0.5 and 1g) as a catalyst and hot distilled water for purification. both produced biodiesel (from Eichhornia and WCO) was characterized using FTIR and some chemical constant such as IV, SV and AV. The highest biodiesel produced from Eichhornia recorded with chloroform: methanol system when compared with Hexane. However, the highest biodiesel produced from WCO was recorded when using KOH (0.25g). Also, the obtained results reported the possibility for use glycerol produced from the both biofuel sources in body butter (makhmaria) production, Authors concluded that, the produced biodiesel from both sources was within the recommended standards of biodiesel fuel. Also, water hyacinth became useful in antioxidant compounds production, the contained pigments may be used as natural coloring substances in different fields.

Biodiesel Feedstocks

Biodiesel is one of the most important types of sustainable alternate bioenergy sources. In developing countries like India, where edible oils are in short supply non-edible plant oils are used as biodiesel feedstocks. In the present work an attempt was made to produce biodiesel from crude neem oil. Due to its high FFA content, neem oil was processed in two steps: acid pretreatment followed by base catalyzed transesterification. The optimum combination for reducing the FFA of crude neem oil to less than 1% after pretreatment was found to be 1.58%v/v H2SO4 acid catalyst, 0.63v/v methanol to oil ratio and 90 min reaction time at a reaction temperature of 60oC as compared to 0.23 v/v methanol to pretreated oil ratio and 23 min reaction time for transesterification. The maximum yield of biodiesel was 90.5%. The properties of produced biodiesel were found quite comparable to diesel and also met the ASTM standards.
