The seeds have a high oil content and a woody husk, both with high potential as raw material to become valuable biofuels in arid and sem-arid areas. The oil makes a high quality biodiesel, whilst fuel pellets made from the husks have a higher calorific value and a lower ash content when compared with other biomass pellets. As a consequence of the high content of fruit pulp that remains in the husk, there is no need to add binders or other additives for the production of the pellets, showing a high durability value[
