Cellulosic Feedstock

Plant life consists of cellulosic resources, cellulose and hemicellulose. Cellulose withstands being separated into its component sugars. Hemicellulose is simpler to break down, however the produced sugars are complicated to ferment. The plant substance lignin also withstands a biochemical alteration. These resources or advanced polymers build and give structure to branches, husks, leaves, plant stalks and trunks. The polymers in paper that are made from these plants. Cellulosic feedstock consists of sugars inside of their cellulose and hemicellulose. The focus from the U.S. Department of energy and other groups of developing a process to break down the parts of biomass as mentioned above has made substantial progress.  With these combined efforts these methods could open the possibilities of cellulosic feedstock for ethanol manufacturing.

Cellulosic feedstock designed ethanol manufacturing range from agricultural crop deposits like corn stalks, wheat straw and husks; forest logging and mill deposits that consists of wood chips and sawdust; rapidly growing grasses like switchgrass; wastes like household garbage, paper products and food handling waste; rapidly growing trees like poplar and willow.

Cellulosic feedstock has numerous benefits over starch and sugar based feedstock. Cellulosic feedstock is much more plentiful that helps generate more significant amounts of ethanol to help provide the U.S with its demand. There are some restrictions or limitations on cellulosic feedstock amounts to be aware of. There is a certain amount of crop residue that can be taken out to help protect and safeguard lands from eroding, but
