Energy Constituents of Jatropha curcas

The energy constituents of J. curcas are wood, fruit as whole and parts of fruit such as shells, seed husks, and kernel (Singh et al. 2008) which are direct sources of fuel. All these products have different energy values. The energy value of these products increases upon processing, but unless a use for by-products is found a decrease in overall energy availability occurs. A schematic illustration of these energy components is shown in Fig. 17.1.
