Oils of a significant value both as fuels as well as for cosmetic applications can be extracted from the fruits of the jojoba plant. After extracting the oil, the remains of the fruit can still be further utilized as a solid fuel in furnaces or feedstock to animals. In the present work, the solid waste jojoba remains have been processed chemically to extract more biodiesel oil. The physical and chemical properties of jojoba solid waste, before and after extracting the biofuel have been measured and presented. Also the properties of raw biofuel extracted from the solid and its methyl ester have been measured and presented. It has been shown that 10% by mass of oil can be extracted from the solid waste. The biofuel produced has been tested in a diesel engine and the solid waste has been also burnt in a furnace for more energy production.
