Processes 
Lignocellulose can be freed from lignin and hemicellulose by chemical treatment to yield cellulose. This can be done by two methods:
1 . Sulphite process. The chopped wood is cooked seven to fifteen hours at 145 C under pressure in an acid solution of calcium bisulphite. After cooking, the chips are free of lignin and hemicellulose and consist of fairly pure cellulose.
2. Sulphate process. The wood is cooked three to six hours at 175 C under pressure in a solution of sodium hydroxide, sodium sulphide, sodium carbonate and sodium sulphate. The wood contains some lignin after cooking.
Nutritional aspects
Ruminants 
Cellulose has long been known to have a high energy value for ruminants. During the Second World War large amounts were used in the Scandinavian countries. When the war ended and cheap energy-rich feeds became available, the use of cellulose as feed ceased despite attempts to lower the cost by producing cheap fodder cellulose from forest waste. The physical form of the cellulose is also important. Ground cellulose is 90% digestible by sheep, but cellulose in the form of torn sheets is only 79% digestible.
Pigs 
It is digestible by adult pigs. The digestibility of the organic matter in average cellulose is 53% for adult pigs and only 37% for small pigs.
Horses and donkeys 
Horses digest it very well.
