PROCESSING BIOMASS Abstract5 Biomass (e.g., plant biomass, animal biomass, and municipal wastebiomass) is processed to produce useful products, such as fuels. For example, systems are described that can use feedstock materials, such as cellulosic and/or lignocellulosic materials and/or starchy materials, to produce ethanol and/or butanol, e.g., by fermentation.10Figure 5 |
