Global potential bioethanol production from wasted crops and crop residues

The global annual potential bioethanol production from the major crops, corn, barley, oat, rice, wheat, sorghum, and sugar cane, is estimated. To avoid con/icts between human food use and industrial use of crops, only the wasted crop, which is de0ned as crop lost in distribution, is considered as feedstock. Lignocellulosic biomass such as crop residues and sugar cane bagasse are included in feedstock for producing bioethanol as well. There are about 73:9 Tg ofdry wasted crops in the world that could potentially produce 49:1 GL year−1 ofbioethanol. About 1:5 Pg year−1 ofdry lignocellulosic biomass from these seven crops is also available for conversion to bioethanol....
