The need of bioenergy due to the world’s increasing population and the limited fossil energy resources, which by combustion are damaging the environment, leads to the demand of renewable energy resources. Waste biomass, especially from agriculture, is an underestimated, but attractive alternative to food-crops for the sustainable production of ethanol from biomass and able to replace petroleum-based fuels.
The conversion-technology of agricultural waste biomass to bioethanol is already at the demonstration-stage. Compared to first generation bioethanol, the second generation fuel requires a more complex preparation-step of the feedstock. Through its wide range of application is bioethanol already applied worldwide and being produced by waste biomass its future looks promising.
