What is wood pulp

Wood pulp is a type of material that is created by processing woods, and serves as the basis for the creation of a wide range of paper-based products. Several different processes are utilized to reduce the wood into a form that is ideal for manufacturing different types of paper goods, including paper used in printing books, magazines, and newspapers. The resulted paper product can also be used to create other paper products, including disposable paper plates, paper towels, and other common household items.

How is wood pulp produced

The process of reducing wood into wood pulp often includes the use of some sort of grinding machinery to create fine chips that can be refined using pressure and steam. This often involves introducing the tiny chips to a steaming process that helps to soften the fibers, making the product more malleable. From there, pressure is exerted to create thin sheets, which are then become ideal paper products.

A slightly different approach to the creation of wood pulp focuses on using a combination of chemicals in the pulp cooking process. This process serves to separate the wood fibers while the material is cooking in the chemical bath. The products produced by this method are more durable than those produced by steaming and pressurizing, and are especially suitable for the manufacture of hardwood based products. For example, sheets made of birch and other hardwood are usually made in this particular way.

Current situation of wood pulp for papermaking

Since the wood pulp is basically wood that has been treated and processed in order to create a usable raw material for different types of paper goods, its range of applications is very broad. This has led to an increased demand for wood pulp over the years. In order to meet the demand, some companies are actively cultivating large areas of land and planting trees that can be harvested. In addition to the felled trees, the pulp waste generated in the manufacturing process is also often recycled to produce new wood pulp. This not only helps reduce the need to cut more trees but also prevents pulp waste from eventually entering landfills.
