&description=The extraction, production and characterization of biodiesel from cashew nut and shell were done using standard procedures. Solvent extraction method was used in the extraction with a percentage yield of 35.5% and 51.60 % for the shell and nut oil respectively, the extracted oils were characterized and subsequently used in the production of biodiesel. Upon characterization of the oil, (the nut and the shell oil), it was observed that the nut/shell oil have these values (173.91/189.34mgKOH), (23.76/36.76mg/I2/g), (0.29%/4.6%), for saponification value, peroxide value, and % free fatty acid respectively. The biodiesel produced was also characterized and shown to have a viscosity of 10.75 at 40oC, acid number (3.079mgKOH), flash point (204.6oC), pour point (7.8oC) and cloud point (12oC). Some of the above properties of the biodiesel met the standard as specified by the American Standard Test Method (ASTM) for biodiesel, with few modification required where variations were observed. The required result obtained show the viability of producing biodiesel from cashew nut oil and the inability of the shell oil to yield biodiesel because it is not a triglyceride.&picture=http://www.aascit.org/aascit/decorators/img/journal/902.jpg)
