ABSTRACT

As a result of concerning food vs. fuel debates, current biofuel development has focused on non-edible feedstock sources. Presently, a large number of non-edible vegetable oils are available, which do not compete with the food industry, so they can provide a source for bio-jet fuel production. In general, non-edible vegetable oil sources are classified into three categories: non-edible plant oils (e.g. Camelina sativa, Jatropha curcas, Nicotiana tabacum and tamanu), recycled oils derived from edible oilseed processing waste, and waste cooking oils. For example, genetically modified canola grown on margin lands has been identified as a sustainable bio-

fuel source because it doesn’t occupy arable land. These margin lands are largely unproductive, or located in degraded forests and poverty-stricken areas. However, the canola plants are well adapted to arid and semi-arid conditions as they can grow on lands with low fertility and moisture, such as fallow lands, cultivators’ field boundaries and old mining lands [1] [2]. Canola seeds contain about 40% oil and they are marketed worldwide [3] . Another non-edible vegetable oil producer is Camelina sativa seed, which is a non-edible oilseed that can be grown on marginal lands with a low input cost. One advantage of this oilseed is its resistance to blackleg, a disease that infects sunflowers, safflowers and many other crops. In Montana State of the United States, camelina is expected to have seed yield of 1800 to 2000 pounds per acre under dry land conditions [4] . Due to the widespread production, the camelina and canola seeds are considered important renewable energy sources.
