Considering the future scenario of non-edible oil seeds utilization for biodiesel production   there is need for efficient utilization of their cakes. The cake neither can be used for animal feeding nor directly be used in agricultural farming due to its toxic nature. The generation of biogas from these cakes would be a best solution for its efficient utilization. Biogas from cake provides energy for heating, cooking, lighting and engine operation. The digested cake slurry can  directly be  put for agricultural farming.   Anaerobic digestion of non-edible oil seed cakes is a good way of cake disposal which provide a better quality renewable gaseous fuel (biogas) than cattle dung generated biogas.
