Eco-friendly Biofuel

Diverse mixtures of native prairie plant species have emerged as a leader in the quest to identify the best source of biomass for producing sustainable, bio-based fuel to replace petroleum.

A new study, published in the Dec. 8, issue of the journal Science, shows that mixtures of native perennial grasses and other flowering plants provide more usable energy per acre than corn grain ethanol or soybean biodiesel and are far better for the environment.
“Biofuels made from high-diversity mixtures of prairie plants can reduce global warming by removing carbon dioxide from the atmosphere,” said David Tilman, an ecologist at the University of Minnesota. “Even when grown on infertile soils, they can provide a substantial portion of global energy needs, and leave fertile land for food production.”
