“…But the requirement of land is much less demanding as compared to those for edible biomass feedstocks preparations [10]. The non-edible biomass feedstocks include mainly the oils from non-edible vegetables, such as Jatropha curcas (Jatropha) [11,12], Linum usitatissimum (Linseed) [13], Simmondsia chinesnsis (Jojoba) [14], Hevea brasiliensis (rubber seed) [15], Azadirachta indica (Neem) [16], Cotton seed [17], Calophyllum inophyllum (Polanga) [11], Nicotianna tabacum (tobacco) [18], Pongamia pinnata (karanja) [19] and Maduca indica (mahua) [20].…”

a b s t r a c tBiodiesel is a renewable and sustainable biofuel. There are various production processes to produce biodiesel from different kinds of raw materials. In this study, the environmental impacts of biodiesel production from non-edible Jatropha oil and waste cooking oil (WCO) were investigated and compared using systematic life cycle assessment. The results show that crops growing and cultivation of non-edible Jatropha curcas lead to higher environmental impacts compared to WCO process. However, biodiesel production process from Jatropha oil has better performance because the WCO process needs to consume variety of chemicals and requires a large amount of energy for the pretreatment of raw WCO and further chemical conversion to biodiesel. Results also indicate that the collection mechanism of WCO has significant contributions towards environmental impacts. In general, biodiesel production from Jatropha oil shows higher impacts for damage categories of climate change, human health and ecosystem quality whereas biodiesel production from WCO has more severe environmental impacts for resource category. The total environmental impact is 74% less in case of using WCO as raw material compared to non-edible Jatropha oil.

“…The FT-IR spectra in the midinfrared region are used to identify the functional groups and the bands corresponding to various stretching and bending vibrations in PBD and the spectra are given in Figure 2. Biodiesel kinds are basically esters which have two characteristically strong absorption bands arising from carbonyl (] C=O) around 1750-1730 cm −1 and that of C-O (antisymmetric axial stretching and asymmetric axial stretching) at 1300-1000 cm −1 [25,26]. The position of carbonyl group in FT-IR is sensitive to substituent effects and to the structure of the molecule.…”

The compatibility ofPongamia pinnatabiodiesel (PBD) and its NaCl blends on aluminium, brass, copper, carbon steel, and mild steel has been studied by static mass loss and rotating cage methods. The effects of dissolved oxygen and flow on the metal corrosion in PBD were also observed. This study confirmed that the copper strip test alone is not enough to determine the fuel property since the corrosion of ferrous metal was found to be high in PBD compared to other metals. The least corrosion rate of aluminium was confirmed by surface morphology and elemental analysis.

“…A large variety of diisocyanates might be employed, however the most used disocyanates are 4, 4-methylene diphenyl diisocyanate (MDI), toluene diisocyanate (TDI), 1,6-hexamethylene diisocyanate (HDI), and isophorone diisocyanate (IPDI). [31] Moreover, recent works have reported the use of jojoba oil to generate biofuels, [32] and the possibility of using it in biorefinery process. [6] Bio-polyols could be an alternative to petrobased polyols.…”

Jojoba grows easily in harsh conditions and is the only plant species known to use liquid wax esters as a primary seed storage reserve. Jojoba oil is composed by two mono unsaturated hydrocarbon chains linked by an ester moiety and represents 50% of the weight of seeds. Hence, this atypical oil is, for the first time, dedicated to the synthesis of innovative polymer materials. Novel partially biobased polyurethanes materials are obtained with various structures. New biobased diol is first achieved by addition of mercaptoethanol by thiol‐ene coupling on jojoba oil and characterized by 1H NMR and 13C NMR. The functionalized oil is used to synthesize polyurethane prepolymers by catalyst‐free reaction with various diisocyanates: 1,6‐hexamethylene diisocyanate and 4,4‐methylene diphenyl diisocyanate. After the addition of chain extenders, the obtained polyurethane materials are characterized by 1H NMR, TGA, DSC, and DMA analyses. Various PUs are obtained in terms of flexibility and thermal stability. Practical Applications: The synthesized jojoba oil‐based PUs exhibit a good flexibility. Hence, these biobased PUs could replace petroleum‐based polyurethanes in industry and particularly as coatings, binders or compounds for automotive and aircraft industries. Innovative greener polyurethanes are achieved from jojoba oil with one‐step thiol‐ene reaction and various diisocyanates.
