Lignocellulosic feedstock
Wood primary (native) plantation primary forest waste secondary processing waste
Agricultural residues straws (wheat, barley, rice) bagasse (sugarcane, sweet sorghum) stover (corn, milo)

- complexity of the raw material -
cellulose(35 – 50%)
hemicellulose(20 - 35%)
lignin(10 – 25 %)
composition:
target:
to separate the lignin and the hemicellulose from the cellulose and to break up the protective skin of the cellulose to make it predisposed for enzymes
