    AbstractHere we proposed clean and acceptable pretreatment methods for the pretreatment of lignlicellulosic biomass. To prove the feasibility of it, we compared three modes of mills such as ball, attrition and planetary mills. Among the mill modes, attrition and planetary mills are more effective to reduce biomass size.
