Jatropha curcas L. is cultivated for its oil utilization as fuel feedstock. This main purpose is achieved with the biomass waste after oil extraction. The biomass wastes are leaf and stem from pruning, fruit hull, seed husk, and oily-cake. This paper discusses the utilization of the waste in order to achieve zero waste of jatropha and develop the jatropha utilizations. Jatropha waste is also utilized as fertilizer, briquettes, adsorbent, resin, and bioactive compost. It can also be utilized as feedstock for production of polymer composite, combustion for gasifier, biogas, liquid oil, and dye. These wide utilizations make jatropha very suitable for biofuel proposes.
