Renewable-fuel feedstock can come from a variety of sources, and each has numerous benefits. Gevo looks at innovative ways that each feedstock could be used to reduce carbon output in the process of producing energy-dense liquids. We also are looking for feedstocks that help to sequester carbon in the soil through the growing process.
Different methods of making biofuel use different feedstock types. Some use the sugar or starch of the plant seed or root of the plant to feed the fermentation process, consuming the plant biomass we generally consider to be a ready source of carbohydrate energy. Still others us lignocellulosic biomass, which feeds the fermentation process with the hydrocarbons stored in the stems and leaves of the plant.
