Answer 2

Answer:

(a) Sulfite waste liquor

Sulfite waste liquor is a dilute sugar solution with about 2% sugar content.

Explanation:

• The spent sulfite liquor from the pulp and paper industry is known as sulfite waste liquor.

• Each tonne of paper pulp generates eight to ten tonnes of sulfite waste liquor.
• Sulfite waste liquor contains dissolved non-pulp wood components, primarily hemicelluloses, as well as the product of lignin sulfonation—lignin sulfonic acid.
• The sulfite waste liquor is converted into alcohol and nutrient yeast.
