Pulp and Paper Making Process - Assignment Point

Pulp is the fibrous cellulosic material used in the production of paper. Wood is the principal raw material for the production of pulp; but bamboo, cotton, linen, rags, straw, bagasse, etc are also used. Chemical pulp production is the cooking of the wood raw material with chemicals.Cooking is necessary to remove the binding agents from the wood.
