I was just thinking that, myself.
The article is inaccurate in saying that eating kudzu back to the root will kill it. It can come back from an apparently dead root after 10 years, or even longer. You have to dig up the root (after eradicating every bit of vine and spreading creepers), and the root can weigh 400 pounds and be as big as a horse.
Can kudzu be made into a bio fuel? It seems as if it has great regenerative abilities.
Kudzu, the scourge of the South.
At our old house, the City of Atlanta had a kudzu-covered abandoned right of way adjoining ours and 3 neighbors' house lots that they never bothered with. Naturally it spread and kept spreading. I dug up roots until I was tired . . . then we got goats.
The trick is that they keep it eaten back continuously -- the roots don't get any nourishment and they die. Took two seasons to get rid of it completely, but we got rid of it.
