University of Minnesota Scientists and Master Gardeners Analyze Biofuel Feedstock Production and Potential to Improve Land Use | BioFuels Journal

A process called pyrolysis makes bio-oil and biochar from biomass such as perennial grasses. The bio-oil may be refined into various biofuels, while the biochar may be used as a fertilizer. If this fertilizer proves useful, it could be an important part of making the pyrolysis process profitable and sustainable.
