Gasoline-like fuels can be made from cellulosic materials such as farm and forestry waste using a new process. The process could open up new markets for plant-based fuels, beyond existing diesel substitutes.

Traditional diesel fuel is made up of long, straight chains of carbon atoms, while the molecules that make up gasoline are shorter and branched. That means gasoline and diesel evaporate at different temperatures and pressures, reflected in the different design of diesel and gasoline engines. Biodiesel, refined from plant-based oils, is already commercially available to run modified diesel engines. A plant-based gasoline replacement would open up a much bigger market for renewable fuels. The feedstock for the new process is levulinic acid, which can be produced by chemical processing of materials such as straw, corn stalks or even municipal green waste. It‘s a cheap and practical starting point that can be produced from raw biomass with high yield.

Essentially it could be any cellulosic material, because the process does not rely on fermentation, the cellulose does not have to be converted to sugars first.
