In many respects, the tallow tree offers the ideal energy crop for biodiesel production along the gulf coast. It thrives in wet areas that cannot be farmed profitably with conventional crops. It has few insect pests and diseases and is tolerant of salt, prolonged flooding and occasional freezing temperatures. It has low nutrient and other management requirements. These characteristics as well as the tallow tree’s exceptional ability to produce high-quality vegetable oil underscore its commercial potential as a low-input, high-return biodiesel crop.
Tallow seeds contain 45-60 percent vegetable oil, about two to three times the amount found in an equivalent weight of soybeans. Yields average 12,500 pounds of seeds per acre containing 2,300 pounds of stillingia oil, 2,500 pounds of wax, 1,400 pounds of protein concentrate, 982 pounds of fibrous coat and 4,000 pounds of shell (endocarp). Per acre, these oil yields are 15 times more than soybeans, 10 times more than sunflower or safflower, seven times more than peanuts and five times more than rape seed. Annual commercial production averages about 645 gallons – the equivalent of 15.4 barrels of oil per acre. Some experts cite figures as high as 970 gallons or 23.1 barrels of oil per acre.
