Revisiting the Jatropha curcas L. as a potential resource of dyes, medicine, biodiesel, bio-pesticide and industrial surfactant.

The plant Jatropha Curvus L. has gained much importance in recent days for the potential biodiesel source but the cost of the biodiesel is not comparable to that of mineral diesel. Therefore the farmers are reluctant to shift towards the farming of Jatropha Curvus L. The present work demonstrates the possibility of multiple product range from the plant and the possibility of processing at farm level. The use of eggshell catalyst for biodiesel production, single pot dying method, and low cost extraction of bio pesticides may open the avenue for farm level production unit making the cultivation of Jatropha Curvus L. profitable. The present work deals with the extraction of dye and production of biodiesel from Jatropha Curvus L. in an eco- friendly way using eggshell based heterogeneous catalyst.
