NATO plants biofuel-grass to clean contaminated military sites

Miscanthus, a fast-growing grass often grown as a biofuel, is now planted on six military sites, from Kansas to Kazakhstan, in a three-year NATO-run effort to clean up contaminated soil. At a conference earlier this month at Kansas State University, researchers reported that the grass stabilizes contaminants in the soil, preventing them from escaping into the air and water, and then gradually absorbs them.
