Abstract
Biomass (e.g., plant biomass, animal biomass, and municipal waste biomass) is processed to produce useful products, such as fuels. For example, systems can use feedstock materials, such as cellulosic and/or lignocellulosic materials and/or starchy or sugary materials, to produce ethanol and/or butanol, e.g., by fermentation.
Claims10
A method comprising:
- processing a treated feedstock to produce a product,
- the treated feedstock having been prepared by pretreating a biomass feedstock comprising at least about 10 percent by weight of a starchy material using a pretreatment method that changes the molecular structure and/or supramolecular structure of the starchy material,
- wherein the pretreatment method is selected from radiation, sonication, pyrolysis, and oxidation.
