In a recent article called Fractional characteristics of jatrooha, neem, moringa, trisperma, castor and candlenut seeds as potential feedstocks for biodiesel production in Cuba. Carlos Martin et. al are trying to find another solution to the question plaguing biofuel production- What is a viable fuel source that does not interfer with food production? All of the above mentioned seeds are not used right now in agricultural production and seem to provide an answer to fuel debate. In analyzing the composition of the remains they determined the viability of all parts for biodiesel production.
The study found the following conclusions:
– Trisperma and jatropha are believed to be the highest potential source of energy as they show the highest combination of proportion of kernal to seed and percent oil of the kernel.
– Jatropha’s fatty acid profile indicating a 74.4% content of oleic and linoleic acids both useful in biofuel production.
– Jatropha is the most promising seed candidate for biofuel production in Cuba.
– Trisperma and castor press cakes, what is left over after a seed has had the oil pressed out, could be potential feed stocks due to their high carbohydrate content.
– Neem, moringa, and jatropha husks show the most promise as feedstocks for biofuel production.
In trying to find a oil seed that can be used to maximize oil production I feel like Jatropha comes out on top. The article does a good job in pointing out that characteristics of these seeds can depend on the location they are grow in, but for Cuba I feel Jatropha is the smart choice as all portions of the seed ( oil, husk, and press cake) can be used in the biofuel process.
