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. It forms a matted or felted sheet on a screen when moisture is removed.
The Pulp & Paper Market has grown signiﬁcantly in recent years, with an upward trend driven by escalating consumer demand and technical developments. The Paper Pulp Market has experienced a spike in product offers, catering to a variety of demands and interests as sectors embrace innovation.
