DSEC's commitment on the construction of Bioethanol plants is based on a very specialized technical knowledge of the Ethanol production processes; in this article you will find a more detailed understanding about the process of Cellulosic biomass. Cellulosic biomass is the structural portion of plants and includes agricultural (e.g. Corn Stover, which is the entire above-ground portion of the corn plant, excluding the grain) and forestry (e.g. sawdust) residues, major fractions of municipal solid waste (waste paper and yard waste), and herbaceous (e.g. switch grass) and woody (e.g. poplar) crops grown as energy resources. Although distinctive in outward appearance, these materials all comprise about 40-50 % cellulose and 20-30 % hemicelluloses, with lesser amounts of lignin and other compounds, such as sugars, oils and minerals. Cellulose is a polymer of cellobiose (glucose-glucose) sugar molecules that are physically linked together in a crystalline structure to provide structural support for plants. Within these micro fibrils cellulose is found in two forms, namely amorphous and crystalline. The crystalline form of cellulose is particularly difficult to degrade and typically makes up the core of a lignocellulosic microfibril.
