The Chinese tallow tree is potentially the best source of plant oil for biodiesel since it is large, very robust, and very fast growing. Moreover, it is extremely fertile and will quickly take over a tract of land with no assistance from the cultivator. But these strengths are also its drawbacks. The tallow tree is considered extremely invasive, and has already become a scourge in a number of Southern States. Many local governments are attempting, unsuccessfully, to exterminate it, and would scarcely welcome enormous plantations of the trees whose seeds could be dispersed far and wide by birds. We are frankly uncertain as to the near and midterm prospects of the tallow tree, and, in any case, we see methyl ester biodiesel as ultimately losing ground to other alternative fuels, and thus the prospects of a cheap though problematic source of plant oil diminishing.
