Process Yields High-Energy-Density Plant-Based Transportation Fuel

A team of University of Wisconsin-Madison engineers has developed a highly efficient, environmentally friendly process that selectively converts gamma-valerolactone - a biomass derivative - into the chemical equivalent of jet fuel. The process preserves about 95 percent of the energy from the original biomass.
