To people in the renewable fuels industry, Arundo donax — also known as “giant reed” — is nothing short of a miracle plant. An Oregon power plant is looking at it as a potential substitute for coal, and North Carolina boosters are salivating over the prospect of an ethanol bio-refinery that would bring millions of dollars in investment and dozens of high-paying jobs to hog country.
But to many scientists and environmentalists, Arundo looks less like a miracle than a nightmare waiting to happen. Officials in at least three states have banned the bamboo-like grass as a “noxious weed”; California has spent more than $70 million trying to eradicate it. The federal government has labeled it a “high risk” for invasiveness.
