In order to choose the most suitable pretreatment is necessary to characterize the cellulosic feedstock adequately. TAPPI and NREL methods have been used widely in recent years. The first one is useful to characterize the pulp and paper feedstock, and the second one is used in the biofuels production. However these methods are not fully accurate for determining lignocellulosic materials composition, such as corncob. Therefore in this work, we improved the characterization method modifying some steps. The stages of extraction and quantification of lignin and hemicellulose were enhanced by implementing separate procedures for each component. This methodology has been used successfully for different types of corncob, municipal solid waste and water hyacinth
