What is the trees pulp?

Pulp is a fibrous material obtained by mechanically or chemically separating the cellulose fibers from wood or other materials, such as agricultural fibers, waste paper, or cotton. Trees are a major source of pulp, and the type of tree used for pulp can affect the properties of the resulting paper. Softwood trees, such as pine or spruce, are commonly used for pulp because they have long fibers that produce stronger paper. Hardwood trees, such as eucalyptus or birch, have shorter fibers and produce smoother and more opaque paper.

Pulp can be produced by mechanical methods, such as grinding wood chips or pulp logs, or by chemical methods, such as the Kraft process or sulfite process. Mechanical pulp is often used for newsprint and other low-grade papers, while chemical pulp is used for higher quality papers and paperboard.

Pulp can also be bleached to remove impurities and improve the brightness and whiteness of the resulting paper. Bleaching can be done with chlorine, chlorine dioxide, or hydrogen peroxide, among other chemicals.

The use of trees for pulp can have environmental impacts, such as deforestation and habitat loss. Sustainable forestry practices and the use of recycled materials can help reduce these impacts.
