University of Georgia Biorefinery (IMAGE) University of Georgia Caption UGA's biorefinery subjects biomass to high-temperature processes, such as pyrolysis and gasification, to produce biochar, or bio-oil gases that can be processed into fuels. The biochar can be used as a soil amendment, returning carbon to the earth, thus promoting the growth of another biomass feedstock and completing the carbon cycle.
