SAWDUST FOR ANIMAL FEEDS
Sawdust contains 50 to 60% cellulose and about 30% lignin. Cellulose is an important component in animal feeds as a source of energy while lignin acts as a barrier to the digestibility of cellulose. Thus, the animals can hardly digest the sawdust. The lignin can be removed or reduced by first treating the sawdust before it is fed to the animals.
Raw materials:
Sawdust, nitric acid, sodium hydroxide
