Pulp
Pulp is a lignocellulosic fibrous material prepared by chemically or mechanically separating cellulose fibers from wood, fiber crops, waste paper, or rags. Mixed with water and other chemical or plant-based additives, pulp is the major raw material used in papermaking and the industrial production of other paper products.

Pulping
There are a number of different processes that can be used to separate the wood fiber:

-Mechanical pulp
-Mechanical pulping process
-Chemi-thermomechanical pulp
-Chemical pulp
-Recycled pulp
-Organosolv pulping
-Alternative pulping methods
-Bleaching
