Utilisation of non edible Seed Oils as Potential feedstocks for Biodiesel Production: A Review

Biodiesel is a promising renewable alternative fuel for diesel engines. Currently edible resources constitute 95% of biodiesel production feedstock. The continuous and large scale production of biodiesel from edible oils has recently been of great concern because they compete with food materials- the food versus fuel dispute. This paper reviewed the prospect of making biodiesel from some non-edible seed oils of Castor, Jatropha curcas, Neem and Yelllow oleander. The review gave physicochemical properties, torque outputs and specific fuel consumptions that are close to those of fossil fuel diesel thus confirming that they can be used as alternative fuels in diesel engines.
